Little to no engagement

BuzzSumo's index contains more than 5.5 billion posts. That's a lot! 

But consider this - MarketingProfs estimated that about 2 million blogs are posted every day. And that report was from 2015.

BuzzSumo prioritizes content that drives engagement to present the most relevant results for topics. While we try to capture as much content, from as many global sources as we can, we sometimes miss articles that have driven little to no shares.

If you suspect we have missed an article, we recommend using our Chrome Extension to check the share count from the original URL. This will both give you the real-time share counts for the page as well as instruct our crawlers to add the article to our database.

Incorrect published date

BuzzSumo follows a sequence of steps to try and discover the publication date when crawling articles.

If we aren't able to determine the correct date of publication, we will use the date we first crawled the article. This may not line up with the date filter you are using. 

We recommend you or your web developer use one of these meta tags in your source code to ensure we attribute the correct date to the article.

Incorrect canonical URL

BuzzSumo uses an article's canonical URL to attribute shares back to the correct article. If this is incorrect, it can cause issues with the share count and our ability to appropriately crawl the correct article.

To check your canonical URL, right click on the page (Ctrl-Click on a Mac) and select “View Page Source."

Then, search for it using Ctrl-F (Command+F on a Mac) and entering "canonical" in the search box. 

If the canonical and article URLs are not the same, instruct your developers or SEO to address it immediately.

Site has many duplicate titles

If your site has identical titles (e.g. HTML title tags: <title>Your Site</title>) that are identical, then we may automatically remove content that appears to be duplicate. 

We recommend working with your marketing team to ensure you are using unique titles across all of your content assets. This will improve not only the accuracy of our crawl but also improve the overall visibility of your content in search.

Bad social share tags implemented on site

We commonly see social tags, such as Facebook’s OpenGraph og:url tag implemented incorrectly. Please check your source code and ensure that each og:url tag points to the correct, canonical URL for your pages. If it’s pointing to the wrong content or (as we often see) the homepage, your site may not be crawled correctly.

Content has recently moved to a new URL

Large changes to a site’s URL structure (for example, you migrated to a new domain to and have set up many redirects for your older URLs) may results in delays in recrawling your content. We ask that you please allow at least 1-2 months for our crawlers to reindex your content.

As a general rule, URLs shouldn’t change often. If you have a large site and are expecting to make this kind of massive shift, please reach out to our Support team.

Content has been considered to be gaming social shares or is spam

It’s possible that your site has been filtered out because our system thinks that it is spam or gaming shares (purchasing likes, tweets or any other form of social engagement).

We strongly advise against this practice as it may result in action taken by the social networks themselves, up to and including removal of profiles from their systems.


If none of these reasons apply and you are still not seeing the results in BuzzSumo you expect, please let our Support team know so that we may investigate.

Content is gated

Some sites that "gate" content  may prevent our crawlers from indexing articles in our database. Some examples of gated content include:

  • sites that require the reader to log in to view content
  • sites that require a subscription to view content
  • sites that require readers to fill out a form before viewing content

If you think we may not be crawling a site for this reason, drop us a line. We'd be happy to investigate.
