Suggested April 2024 Running A Profitable Business: Best Practices For Pricing

Many people run a small business without knowing what makes a successful or profitable business. There are many techniques that successful businesses use to grow and generate revenue, which is why it is beneficial for entrepreneurs to learn these strategies for themselves.

The following write-up has compiled some of the best strategies one can use if they are running a profit-driven company. The full article will go over the ideas in detail and provide effective pricing practices you can implement into their company’s operations.

How Pricing Strategies Help Running A Profitable Business

There are a plethora of ways to increase your revenue. However, the best way to do this is to know how your company maximizes its profits. Revenue is generated by selling your product or service at the right price. It may seem obvious, but the key to maximizing profits is having an idea of what makes a profit and choosing pricing strategies that benefit this goal.

It is important to use a software pricing company that will make a business profitable in order for it to become successful. Below you will find the most popular practices for pricing that increase revenue and overall profitability.

Best Practices For Pricing

The marketing and pricing techniques below are the most common practices business owners use. Some of these techniques are simple, and some require additional price structures, but they all aim to improve profits.

Competition-Based Pricing

Cost-Plus Pricing

Cost-plus pricing is an approach that sets a price high enough to pay all the expenses for setting up and running the business, including wages for each staff member and other costs. Then the remaining profit is divided among the owners.

Dynamic Pricing

Dynamic pricing is the use of changing your price on a regular basis for your product or service. For this strategy, you set prices for different time periods. For example, you may set up a five-day price cycle and offer five discounts over the course of the week. The idea is that there are often various “deals” that can be had over the course of a week because people do not have time to purchase much during certain days, therefore only going to purchase those things they truly need when they know they will have time to purchase them during that time frame.

Hourly Pricing

Hourly pricing is a relatively new form of pricing strategy. It is in vogue for online commerce because it allows businesses to efficiently enter a market with an uncertain amount of time before customers decide to purchase. Most online stores now use hourly pricing for their products and services, much like stores that have items purchased by the hour and therefore must be selected from an inventory rather than ordered and have no price listed.

Skimming Pricing

Penetration Pricing

Penetration pricing is the opposite of skimming. Instead of raising your price to the highest level you can, penetration pricing has you setting your prices at a low amount to entice consumers to buy your product or service.

Project-Based Pricing

The idea of project-based pricing comes in the form of a quote. For every product or service, there is a starting price that you are willing to accept. A quote with a range of charges allows businesses to be flexible to their customer’s needs while maintaining profitability and quality.

Value-Based Pricing

Value-based pricing is another form of pricing strategy that involves acknowledging the value of a product or service while also considering its cost and likability. This requires the use of statistics to properly price products like software.

Bundle Pricing

The Bottom Line

Pricing is a very important area of your business operation. If you are selling a product, you must make sure that you are pricing it at a level that is both high enough to keep profits and low enough to gather interest from the consumer.

There are many different strategies for pricing your products and services and ultimately finding the perfect one for your business or brand will depend on what type of industry you are in and what the needs of the consumers are.

25 Instagram best practices for 2023

Instagram marketing best practices

1. Set clear goals

You’ve heard this from us before and you’ll hear it again. Every great social media marketing strategy begins with a solid set of clear, measurable goals.

Are you planning to use Instagram to build brand awareness? Drive product sales? Engage with your community? Maybe all of the above?

What you want to get out of Instagram will determine what you should put into it. Think about how the platform’s various surfaces – feed posts, Reels, Stories – can contribute to real business goals.

2. Post at the right time

Hootsuite research shows that the best time to post photos on Instagram is 11 a.m. on Wednesdays. For Reels, it’s 9 a.m. and 12 p.m. Monday to Thursday. Keep in mind that the average Instagram business account posts 1.71 main feed posts per day.

That’s a good place for you to start. But to find the most effective time to post for your particular account, you’ll need to understand the Instagram habits of your particular audience.

Hootsuite Analytics provides a heatmap showing when your followers are most likely to be online. It also provides custom suggestions for the best time to post to your followers based on your chosen Instagram goals.

This allows you to create quality content in dedicated blocks of time, which maximizes your creative resources. It also gives you the breathing room to edit and review your content thoroughly before it goes live.

Hootsuite helps you post consistently with no effort. It allows you to schedule your Instagram posts, Reels, and Stories alongside other social posts, so you can see the complete picture of your social posting schedule in one content calendar.

This also gives you a good overview and allows you to ensure you’ve planned the perfect mix of photos, videos, and carousel posts.

4. Engage with your followers

Remember: Instagram is not a broadcasting service. It’s a social network. That means your followers expect two-way communication and a sense of community. If you want people to engage with your Instagram content, you’ve got to get engaged yourself.

Start free 30-day trial

5. Tag your products

Nearly half of Instagram users shop the platform weekly.

Brands that tag their products in feed posts see 37% more sales on average. And brands that tag two or more posts per day see a 117% increase in transactions.

6. Analyze and improve your results

We’ve already mentioned a few times that you’ll need to do some experimentation to learn what works best for your particular audience. That will continue to be an ongoing theme throughout this post.

To learn the results of your experiments, you need to use Instagram analytics. The native Instagram insights tool provides some good information to get you started. To take things up a notch and get a richly detailed picture of your results, it’s a good idea to incorporate professional analytics tools like Hootsuite.

The Instagram analytics within Hootsuite include downloadable and exportable charts and graphs that make it easy to understand what’s working and what’s not. You can also see how your Instagram efforts compare to those on other social media platforms.

Instagram Reels best practices

7. Make (more) Reels

Not using Reels yet? It’s definitely time to start.

Instagram is leaning hard into video in general and Reels in particular. Reels already account for 20% of time spent on the platform. And Hootsuite research shows that Reels get up to 300% more engagement than regular Instagram videos. The Instagram algorithm loves Reels, too.

So, this is a simple but very important Instagram best practice. Just make (more) Reels.

8. Show your human side 9. Make the most of the first 3 seconds

Capture attention right upfront with dynamic motion and teaser titles. (Just make sure you deliver on the promise of your title – watchbait is a big no-no.)

Show (and tell) people in the first three seconds what they’ll get out of your Reel and why they should keep watching. On that note…

10. Add text to your Reels

Adding text to your Reels offers a number of benefits. First and foremost, it makes your content accessible to the deaf and hard-of-hearing community. It’s also important for the 20% of Reels views that happen with the sound turned off.

You can also add timed text to emphasize specific points in your video.

11. Use trending audio

Incorporating trending audio into your Reels is a great way to boost your exposure. You can identify trending audio by the little arrow next to the name of the sound in any reel.

Source: @biabeible

Tap on the audio to see how many reels have already been made with that sound. Your best chance for getting a boost is using trending audio that doesn’t yet have too many other competing Reels. Aim for 30K or fewer.

In this case, the track already has 285K Reels, so you might want to keep looking for one with less competition.

Source: Instagram

If you come across audio you love, you can save it for later by tapping the Save audio button. If you specifically want to use it for that trending boost, just be sure to check that it’s still trending when you’re ready to use it.

12. Try a template

If you want to use multiple photos and/or video clips in your Reel, a template can be a great way to get started. Using a template automatically syncs your clips to the audio in the original Reel.

Instagram Stories best practices

13. Use interactive stickers

Interactive features like the vote button, quiz button, and question button really let you get to know your audience. They also provide a great opportunity for getting your community involved and driving good engagement rates.

Source: @yoga_international

Try asking followers what kind of content they want to see from you. Or use the Question sticker to do a follower Q&A.

14. Save your best Stories to highlights

Instagram Stories are a great way to experiment with new ideas and more casual content because they disappear after 24 hours.

But sometimes you want your Stories to stick around. For those occasions, there are Stories highlights.

Highlights live on your Instagram page above your grid. In addition to saving your best Stories, you can also use them to create space for extra information about your business or products.

Instagram post best practices

15. Develop a consistent style

Your Instagram grid should have a visually consistent style, and viewers should be able to recognize one of your posts instantly when it appears in their feed.

One way to achieve this is to keep the colors you use in line with your brand style guide. Another is to use design tools with pre-built templates, like the Canva integration in Hootsuite Composer.

16. Use the right hashtags

Social SEO may be reducing the importance of hashtags, but that doesn’t mean you can avoid them altogether.

In particular, using specific niche hashtags can help you connect with existing passionate communities on Instagram. And creating a brand hashtag can help you collect user-generated content and social proof.

Here’s everything you need to know about using hashtags on Instagram:

17. Write catchy captions

Yes, it’s the quality of the image that will grab attention and stop the scroll. But you can’t ignore the power of captions on Instagram. Instagram captions help users connect with your brand and learn about what you stand for.

Writing great captions is also one of the best practices for Instagram posts because they help the Instagram algorithm understand what your post is about to help with Instagram SEO. Captions are one of the sources the algorithm checks for relevant keywords when someone searches for content on the platform.

18. Use alt text

This is another quick thing you can do to make your content more accessible while also boosting your Instagram SEO ranking signals.

Alt text on Instagram works just like alt text on the web: it provides a text description of what’s in the image or photo.

Instagram uses artificial intelligence to create auto alt text for all posts, but you can customize the alt text yourself for better results.

Check out our detailed instructions for adding alt text to Instagram posts.

19. Pin your best posts

The first three spots on your Instagram grid are prime real estate. Fortunately, you can now choose what appears there. You can pin up to three posts (or Reels) to the top row of your grid.

Try pinning your most popular posts, or your most timely. Have a promotion going on? Or a new product about to launch? Pinned posts keep users’ eyes on the prize.

You can also get creative with pinned posts, as Rocky Mountain Soap Company did to tease a new product launch:

20. Experiment with ad placements

As with your organic strategy, you’ll need to do some testing to see which placements tend to work best for your audience and your goals. The important thing is not to get locked into one format and rely on it to serve your needs. Instagram is constantly changing, so it’s important to keep testing to see if the effectiveness of various formats ebbs and flows with time.

21. Partner with creators 22. Unify your product catalog

Here’s how to get your product catalog set up:

The Shopify integration in Hootsuite makes this easy if you already have a Shopify store.

Instagram bio best practices

23. Make it complete

You don’t have a ton of real estate in your Instagram bio – just 150 characters to tell users who you are and why they should stick around.

But you can bulk this up by completing all the fields available on your Instagram profile – like your profile picture, address, a link, and an account category. On that note…

24. Choose the right account category

Using the correct category in your Instagram bio makes it easier for people to find you and understand what your brand is all about.

It’s also an important feature for enhanced tagging. If you collaborate with other brands or creators, enhanced tagging shows each account’s contribution to a post, including the account category.

25. Get verified

To give more credibility to your account, think about getting that blue check and applying for Instagram verification. Instagram verification goes a long way in helping your business account look more professional while preventing impostors from stealing your thunder.

Top 5 Mlops Best Practices For Organizations In 2023

MLOps is defined as certain practices that ensure the deployment and longevity of ML systems by performing the necessary maintenance for updated versions. Due to its potential benefits MLOps market has grown rapidly: According to Deloitte, the market will be worth $4 billion in 2025, predicting a nearly 12-fold increase in MLOps market size since 2023.

Despite all the benefits ML brings to various business processes, companies are struggling to deploy ML techniques to enhance their efficiency. According to McKinsey, 64% of respondents cannot deploy ML algorithms beyond the pilot stage.

Therefore, we list some of the best practices for implementing MLOps to your business problems.

Defining the business problem

A clear business objective is critical to the deployment of successful MLOps. What is your business goal? Increasing production efficiency or profitability, improving sales, etc. With this decision, the company determines the KPI that the ML algorithm should maximize.

Promoting team-work

Coming up with successful ML practices is something like making a movie. The stars of the movies are actors but their accomplishment depends on many invisible heroes. The same rule applies to deploying MLOps.

Let’s say your business goal is to increase revenue by 5% without impacting profitability metrics. To achieve this goal, the IT team needs to know the key parameter values that impact revenue. Therefore, they need to communicate with the sales and marketing departments.

The IT team also needs to know the components of fixed and variable costs to protect profitability metrics. Therefore, the finance department must be asked. Otherwise, it would be impossible to write suitable algorithms. Such a task requires teamwork, where the departments can communicate with each other.

However, as a challange to teamwork Deloitte’s study highlights 68% of managers believe that the differences in qualifications between employees are at least moderate. The greater standard deviation of qualifications could mean further difficulties for the communication process. In addition, it means that at least some companies will have to rely on a small portion of their workforce to accomplish a difficult task such as implementing MLOps.

Make a cost benefit analysis

Be clear about what features your business needs from MLOps. This approach is the key to the optimal processing of any transaction. Imagine you are a customer who wants to buy a car. You have many options, of course. For example, there are sports cars, SUVs, compact cars and luxury cars. For a cost-optimal purchase, you need to understand which category suits your needs and then compare the different segments and models according to your budget.

The same rule applies when deciding on the optimal MLOps tool for your business. Different MLOps have weaknesses and strengths in accomplishing certain tasks, such as sports cars and SUVs. Therefore, to make a strategic decision, you need to consider several factors, such as your business goals and budget, the MLOps tasks you want to undertake, the format and source of the datasets you want to work with, the capabilities of your team, etc.

Validating datasets

The more extensive the data is, the better the reality is represented. Creating a dataset for analysis requires cleaning the data from biases and combining data from different sources (both external and internal).

Batching is another important technique for interpreting data based on changing the frequency basis for a given set of data extractions. In this way, efficient ML training becomes more likely. Also, to ensure data reliability, data pipelines should be automated to control the orchestration of the various data collections. Finally, it is important to consider that development, testing, and production processes may require the use of different data sets.

Finding optimal outcome by experimenting

The great British philosopher John Lock viewed the human brain as a white board waiting to be filled with information that is the result of a process of trial and error.

Machines also use a very similar method for learning. Thanks to protocols that guarantee the reproducibility and analysis of the tests or experiments, ML systems gain experience from their mistakes, which eventually lead to better predictive capabilities. The goal of the method is to shorten the life cycle of analysis development and enhance model stability by automating reputations in the workflows of software experts.

Etl Testing Best Practices In 2023

Extract, Transform, and Load (ETL) is a crucial process in data warehousing, where data is extracted from multiple sources, transformed to fit the target schema, and then loaded into a data warehouse. ETL testing is a critical step in ensuring the quality and accuracy of the data loaded into a specific location.

ETL testing is a complex and challenging task that requires a deep understanding of data and the ETL process. In this article, we will discuss some of the best practices for ETL testing that can help you improve the quality of your data and minimize errors during the ETL process. ETL testing can be helpful for sectors that handle a lot of data, frequently from different sources.

1- Automate your testing

Automation in testing is essential to ETL testing best practices. Automating your ETL testing processes helps you save time, reduce errors, and increase efficiency. You can use ETL testing tools to automate repetitive testing tasks and generate detailed reports.

2- Understand the data

To perform ETL testing effectively, it’s crucial to thoroughly understand the data being processed, including its


Format Structure,

Expected output.

This knowledge will help you identify potential issues and anomalies in the data, ensuring that the final output meets the business requirements.

3- Plan your testing strategy 

Develop a comprehensive ETL testing plan that covers all aspects of the ETL process, including data extraction, transformation, and loading. This plan should define the testing scope, methodology, expected outcomes, and tools &resources required to execute the plan.

An example of a testing strategy could be in the following order:

Data Extraction Testing: Verify that the data is being extracted from the correct source system

Data Transformation Testing: Verify that data is being transformed correctly and consistently

Data Loading Testing: Verify that the data is loaded into the correct target system

Data Reconciliation Testing: Compare the data in the source system to the data in the target system to ensure that the data has been accurately transformed and loaded

Regression Testing: Conduct regression testing to ensure that changes to the ETL process do not impact existing functionality. Verify that the ETL process works correctly after system upgrades or changes.

Performance Testing: Test the performance of the ETL process for both small and large data sets. Verify that the ETL process performs within acceptable time and resource constraints. Investigate and resolve any performance issues.

Error Handling Testing: Test error handling for different scenarios, such as invalid data, network failures, and system errors

Security Testing: Test the security of the ETL process, including data encryption, authentication, and access controls. Verify that the ETL process complies with regulatory and security requirements.

4- Use test data wisely

The quality of your test data is critical to the success of your ETL testing efforts. Use representative data sets that simulate real-world scenarios and edge cases and cover various data types and formats.

Real-world scenario data:

Patient demographic data, such as: name, age, gender, and contact information

Medical history data, such as: diagnoses, medications, procedures, and allergies

Claims data, such as: billing codes, dates of service, and insurance information

Provider data, such as: physician names, practice locations, and credentials

Edge case data:

Patients with unusual or rare medical conditions that require special handling

Patients with multiple or overlapping medical conditions that require complex data transformations

Claims with incorrect or incomplete billing codes

Invalid or missing patient and provider information

5-Verify data integrity

As part of your ETL testing efforts, you should verify the integrity of the data being processed. This includes checking for data accuracy, completeness, consistency, and conformity to data standards and rules.

Here are two ways to verify data integrity for ETL testing:

Data profiling: Profiling the data before and after the ETL process can help you identify data quality issues, such as missing or duplicate data, and validate the accuracy of the data. Data profiling tools can help you compare source data to target data, identify patterns and anomalies, and highlight discrepancies.

Data reconciliation: Comparing the data in the source system to the data in the target system is an effective way to verify data integrity. You can identify missing, duplicated, or inconsistent data by comparing the source and target systems data. You can also use data reconciliation tools to automate this process and generate reports highlighting discrepancies.

The ETL process transforms data from its source to the target format. It’s essential to validate these transformations to ensure the data is transformed correctly and consistently. You can use two crucial aspects of software testing to complement ETL testing and strengthen the ETL process:

Unit testing: This testing is typically done using mock data and test cases that cover various data scenarios. By testing each transformation individually, you can identify and fix any issues early in the ETL process.

Integration testing: Integration testing involves testing the entire ETL process to ensure that the data is transformed accurately and consistently. This testing typically uses real-world data and test cases covering various data scenarios. You can identify and fix data transformations and flow issues by testing the ETL process.

7-)Test data loading 

The final step in the ETL process is to load the data into the target system. It’s essential to test the data loading process to ensure that the data is loaded correctly and that there are no data loss or corruption issues.
