Facebook Comments Robots Block Impacts Website SEO

Recently we added Facebook Comments to this blog thinking they would improve engagement among site visitors. But a robots.txt block spoiled the fun.

Facebook Comments Blocked Resources
Read how our project embedding Facebook comments to this blog is blocking resources needed for good seo and page rank.

Facebook users as a rule stay signed in when going to other places on the net. So having FB Comments installed makes it quick and easy to leave a blog comment on an article. Sounded like a win-win scenario.

Unfortunately we discovered today that FB is putting a robots.txt block on our comments url. We found this out when visiting our Google webmaster tools account. Our Facebook page thumbnail was blocked by their robots.txt file.

We also ran into this situation once before after embedding videos from FB. Everything from the social media giant will cost ya – one way or another.. 😥

Google explicitly says that Blocked Resources will effect a websites indexing in their search.

Googlebot needs access to many resources on your page in order to render and index the page optimally. For example, JavaScript, CSS, and image files should be available to Googlebot so that it can see pages like an average user.

If a site’s robots.txt file disallows crawling these resources, it can affect how well Google renders and indexes the page, which can affect the page’s ranking in Google search.

So if your considering adding Facebook Comments to your external Website Blog or Forums consider this scenario. It will effect your page rank!

Update 04/17/17: There are different opinions on the SEO impact of Facebook comments. One article i read said blocked external resources do not have a negative SEO impact.

Thus considering it’s the Facebook users thumbnail image being blocked, but not the comment url itself, we have enabled our Facebook comments.

Our blocked resources have went from 0 to 10 since enabling comments. Google still is vague on this subject. Will report back if any major SEO changes occur. 😉

Update 03/20/17: Page rank is dropping like a rock, according to Google webmaster tools act.

I'm a Florida-born good ole southern boy hanging out online keeping up with tech. Being a TV technician from the early 70s I felt right at home when the net was released to the public. I blog my opinion about many worthy subjects as a hobbyist. If you find this article's information helpful please comment and share wherever possible!
