I am thinking about using a JS script that lazy loads HTML when scrolling ( http://ivorycity.com/blog/2011/04/19/jquery-lazy-loader-load-html-and-images-on-scroll/).

I am not too sure about whether this approach is SEO friendly. As far as I know, search enginges ignore text within comments. Even worse, the site might get degraded because of so many comments. How should I handle this requirement? Are there any alternative approaches?

Since November 2011 The Googlebot has been able to read AJAX/javascript content, facebook, Google+ and twitter content etc. Since Matt Cutts specifically mentioned comments in his tweet I believe your content will get indexed.

Matt Cutts of Google Tweeted yesterday that “Google can now execute AJAX/JavaScript to index some dynamic comments.” which means its web crawlers can now ‘read’ some dynamically generated content previously hidden. Exactly how much of this content is unclear. However, he does specifically mention the word comments rather than all Ajax/JavaScript. This is still fantastic news for our developers who love nothing more than to include complex functionality into their web design whilst maintaining search engine friendliness.

Since Google is also indexing Facebook and Twitter comments and I notice comments on the envato network turn up frequently in search results I don't believe you'll be penalised for having too many comments. But the article I linked to above does state:-

With Google crawling and indexing comments, moderation will become more important than ever. Website owners and administrators should pay close attention to their comment sections to ensure they aren’t in violation of Google’s Webmaster Guidelines. Too many comments left for trolling and spamming purposes will result in a negative PageRank, while hate speech could result in blacklisting.

So best to have a read and keep a close eye on what people are saying on your site.

  • Thanks for your comprehensive answer. Very good to know about this! Unfortunately I was not talking about comments as a reaction to an article. But comments as in commenting HTML code in order to hide it from the browser.

  • @marlene For the same reasons that I address above you should be fine, google is capable of distingushing excessive commenting from code with comments.
