How to Find Reliable Data for Web Scraping

Reliability, validity, and accuracy are some words that come to mind when data is mentioned. While getting data is important to run a business, the data’s reliability, validity, and accuracy are often more important.

Brands want to gain business intelligence and craft insights that will floor their competition, but this cannot be achieved by using inaccurate data from unreliable sources.

And because today, anyone can set up a website and pour whatever data they want on it, it has become very easy for people to run into low-quality data.

Smart brand owners need to evaluate the data they use, and this begins by finding a trustworthy and reliable data source. Perhaps, this is why many prefer to use C# web scraping (web scraping with c# – blog | Oxylabs) or web scraping done with tools built with the most useful programming languages, as they are reliable at identifying good data sources.

What Is The Importance of Reliable Data?

Reliable data is crucial in the battle to win more of the market share and stay ahead of your competition, and very often, the better the quality of data you employ, the better the decisions you make, and the more you dominate your niche.

Below are some of the most common reasons why reliable data is so important:

  • Reliable data helps to make informed decisions so that the higher the data quality, the better the decision
  • It helps to increase profitability for the business
  • Reliable data is the best way to gain a competitive advantage
  • When the data is reliable, it becomes easier to implement, and the company’s efficiency increases
  • Reliable data makes it easier to target the right customers and offer the most satisfying products and services.

Why Is It Important to Carry Out Evaluation Before Picking Data Sources?

Now that we have discussed why it is important to use reliable data, let us see why it is important to evaluate the source you are getting your data from.

1. Relevance

When you search for data, you will need to ensure you are getting data relevant to your business. This means the data needs to meet your business goals and use. Data can be relevant to one business and be irrelevant to another depending on each need.

Therefore, it is paramount to evaluate a data source to ensure its content holds relevance for your digital company.

2. Accuracy

Accurate data describes real-life conditions as they are. They contain facts and figures as they are. Decisions based on accurate data often lead companies to significant progress, while those made from inaccurate data can cause incorrect conclusions.

It is often necessary to determine the accuracy of the data you are scraping by first evaluating the source.

3. Validity

Checking the data source can also help you discover the data validity, which means that the data is in the correct format and meets the set criteria.

4. Currency/Timeliness

It is easy to run into outdated and not current data when you do not first evaluate the source.

Outdated information may be correct, valid, and even relevant for your business but won’t work because it is no longer current.

5. Completeness

The last thing you want is data filled with holes and gaps, missing parts, and incomplete information.

For a decision to lead to a breakthrough, it needs to be backed by whole and complete data. And the only way to check the completeness of data is first to scrutinize the source.

6. Consistency

Data consistency cannot be overlooked. This is because inconsistent data often contain variations and differences between multiple versions.

Such inconsistency can cause different parts of your organization to work with different and sometimes opposing assumptions. This leads the company backward at most.

You can avoid this by running a complete evaluation of the data source before collecting the data.

Suggestions on How to Pick the Best Data Sources

The following suggestions will help you pick the best data source for your next Python or C# web scraping session:

  • As much as possible, avoid servers and websites that disallow scraping bots. This is not only because of the legal implications of scraping those sources but because you could also lose data when you get blocked.
  • Only scrape from sources that contain relevant and fresh data. Websites that regularly update their content will help you make better decisions and grow faster.
  • Avoid sites with broken links. URLs are what bots follow to collect more relevant and useful data, and the process can get taunted when the scraping bot encounters a broken link.
  • Check to confirm that search engines rate the data source. Search engines such as Google usually have algorithms that rank the best websites at the top and eliminate bad or spammy websites.


Data can help you win the type of competitive advantage needed to dominate the market. However, it would be best if you were wary of where that data is coming from.

You are encouraged to properly evaluate any source to find reliable data for C# web scraping or any type of web scraping.

Following the suggestions provided above could help, but most of what you settle for would depend on your needs and niche.
