The question is, "Do comment links from other blogs that have nofollow links on comments count as a backlink to your website?".. and the answer is yes, without a doubt!
One of the arguments I here quite often in the SEO world is the value of commenting on other blogs and if the no-follow backlinks from them carry any SEO backlinks that result in SEO Juice?
For years I have been saying they do, but recently I saw a post that said commenting on blogs with no-follow links did not get indexed, but I am here to put an end to that myth. Your comments on blogs do carry backlink juice, whether they are a no-follow link or not.
The image below is from SEO-MOZ and show indexed backlinks to the SEO-Alien… the first 4 listed are comments that I have made on other blogs that SEO-MOZ says are not only indexed, but also show they are nofollow links.
SEO MOZ Indexed nofollow Blog Comments
Just in case you need more proof that noindex links are indexed, I got it… Using a Google backlink tool checker I found these results.
Furthermore, after doing a little more research, I found this directly from Google;
How does Google handle nofollowed links?
nofollow causes us to drop the target links from our overall graph of the web. However, the target pages may still appear in our index if other sites link to them without using
nofollow, or if the URLs are submitted to Google in a Sitemap. Also, it's important to note that other search engines may handle
nofollow in slightly different ways.
Creating Quality SEO Backlinks
Backlinks, (aka "incoming links") are valuable for your website, but more importantly than the amount of links are the quality of the link.
In the "Old Days", the more inbound links you have, the higher your overall Google Page Rank. But today, Google and the other search engines that matter, reward quality over quantity.
When it comes to creating SEO backlinks, Google prefers natural links, such as blog comments, however, low quality links may hurt you more than help so it is important that if you are commenting for backlinks, you should be doing it from sites that have a great reputation. A simple way to check reputation is using the Google Pagerank tool.
In a nutshell, it is better to have 10 quality backlinks than to have 100 low quality backlinks.
Other ways to create quality SEO backlinks are from creating profiles on Social Media sites and other popular Social bookmarking sites.
