History and background

What is BlogRank?

BlogRank is a comprehensive system that collects data on thousands of blogs, and ranks them in different categories based on over 20 different factors, using a unique formula. It was launched in May 2009 and took us over 8 months to develop, with over 20,000 blogs and 50 categories. You can learn more about how BlogRank works here.

What inspired you to develop BlogRank?

We have been publishing the Invesp blog regularly for the last three years and wanted to know how to measure its success, reach or influence. With this in mind, we decided to examine different factors to measure each of these elements, such as how many people read a blog, how many people subscribe to the RSS feed, how many other blogs link to your blog and more. Our aim is to help readers find the best blogs possible in the area of their interest.

Ranking Logic & Algorithm (how does blogRank work)

How does BlogRank work?

We use over 20 different factors to rank a blog, such as (but not limited to):

  • RSS membership
  • Yahoo incoming links
  • Yahoo indexed pages
  • Google indexed pages
  • Google PageRank
  • Monthly visitors
  • Pages per visit
  • Link to page ratio
  • Compete, Alexa, and Technorati ranking
  • Social Sites popularity (Digg first page stories, Stumbleupon reviews, Delicious bookmarks, Redditt, Propeller and mixx)

These factors are not all given the same weight. Factors which can be manipulated such as, incoming links and pages indexed by Google or Yahoo, have less weight compared to factors such as, pages per visit or RSS membership. Additionally, each blog receives different weight for the different factors depending on the category it is listed in, because it is measured against all the blogs in that particular category. For example, if a blog is listed under two categories: social media and blogging, it will most likely receive different points for RSS membership, Digg first page stories, Compete Ranking, etc in these two different categories.

How is BlogRank different from Technorati’s Authority ranking or other blog ranking systems?

The most well known system in ranking blogs is Technorati. The biggest differences between BlogRank and Technorati’s Authority ranking are:

1) Technorati’s Authority ranking is not focused on listing the top 100 blogs in specific categories across the blogosphere.
2) Authority ranking relies solely on incoming links to a blog for its ranking. This is only one of the factors we use in ranking blogs.

Most other ranking systems use only 8 or 9 factors to measure a blog’s success, while we use over 20.

Why does my ranking keep changing?

To reflect the most accurate data possible, our rankings are updated on a daily basis. Although the changes are not drastically different from one day to the next, they will continue to fluctuate as more blogs are added to our system and as different blog data changes over time.

Why do the top blogs outrank my blog?

BlogRank uses a proprietary algorithm to come up with the final ultimate rank. We use over 20 factors in coming with our final calculation. Not all the factors are assigned the same value. While your blog might outrank one blog in RSS membership, there might be other factors that give the other blogs more power over yours.

How often do you update the data for my blog?

We retrieve data from blogs on a daily basis. Because data is being collected from over 20 different external systems, there is always the possibility that some of these systems will not respond to our requests. However, we continously strive to improve our systems to ensure that our data is as accurate as possible.

Why do I not see my category listed in BlogRank?

BlogRank is still in beta. In its first release, we only had 50 categories. Every few weeks we continue to release new categories with new blogs. We try to work out most of the application issues before releasing all the different categories. If you have any suggestions for new categories, please open a support ticket to suggest new categories.

Why isn’t my favorite blog listed?

We started with about 20,000 blogs when we first released the application. Although we have collected a lot of blogs, we haven’t collected them all. Visitors continue to add hundreds of blogs every day, so we are hoping to grow the list as much as possible. If you have suggestions for new blogs, please open a support ticket. If you are feeling generous and have few moments, you can add the blog directly to our ranking system.

Incorrect Data

Why is my Compete score listed as 0?

If your blog is hosted on a subdomain (i.e. http://blog.mysite.com) or a subdirectory (http://www.mysite.com/blog), Compete's API does not provide data for your blog. Please note that if your blog is on a subdomain or subdirectory, we are still able to retrieve data from the main site but not for the blog. Our system uses data for the blog and not for the main site in the ranking logic.

Why is my Alexa score listed as 0?

If your blog is hosted on a subdomain (i.e. http://blog.mysite.com) or a subdirectory (http://www.mysite.com/blog), Alexa's API does not provide data for your blog. Please note that if your blog is on a subdomain or subdirectory, we are still able to retrieve data from the main site but not for the blog. Our system uses data for the blog and not for the main site in the ranking logic.

Why is my RSS feed listed as 0?

Our system is currently only able to read data from FeedBurner URLs (i.e. http://feeds2.feedburners.com) and those URLs must have their Awareness API activated. In other words, you must use a FeedBurner URL for subscription to your RSS feeds that has its feed count enabled. We are working on adding a new functionality to estimate RSS membership for non-Feed Burner URLs. We will update this page once the issue has been resolved.

Why is your data inaccurate? I get a lot more visitors a month compared to what you report.

We use Compete to report the total monthly visitors for a blog. While Compete data is not 100% accurate, it is relatively accurate across several blogs. For example if Compete is only reporting 20% of your blog visitors, then you can safely assume that it is also only reporting 20% of the other blogs in the same category. We currently do not have a way to validate the total number of monthly visitors, however future releases of BlogRank will provide that functionality. We will update this page once the issue has been resolved.

Can I send you an image from my analytics/cpanel report to show you the real number of visitors?

We have to find a standard way to report the same data across many blogs. We use Compete to report the total monthly visitors for a blog and will not accept images from analytics to update your monthly visitors.

Why are my Propeller, Mixx, Reditt, and StumbleUpon reviews inaccurate?

Only reviews for the website or the main page of your blog from the above social bookmarking websites are recorded in our database. We are currently working on ways to incorporate reviews from different aspects of the blog or posts.
