The average blogger probably doesn’t care about SEO but what if I told you that blogging too much may actually hurt your blog? And that having too many webpages may cause your website to drop in rankings or even disappear from search engine results? Apparently, Google takes the sum of all the inbound PageRank to your domain (larrylim.net in my case) and divide it by the number of pages to obtain an average. And if that average Google PageRank is below a certain number or threshold, your webpages will fall into Google’s Supplemental Index. This theory is consistent with what Matt Cutts said at SMX: “If you got 60,000 pages, and you only got “this much” PageRank, and you divide it […he mumbles], some of them are going to be in the supplemental index. Given “this many people” who link to you, we’re willing to include “this many” pages in the main index.” Consider this from Google’s point of view that they prefer you to write useful content and which will usually attract natural backlinks, it makes perfect sense. In other words, it’s better to write 1 high-quality blog post than 100 low-quality ones. And if you already have a bloated 10,000-page website, consider reducing them by blocking less desireable webpages using robot.txt. Bottomline? Think twice before writting unnecessary blog posts or webpages for the sake of adding fresh content to your website for SEO reasons. Remember that Google has over 200 checks when ranking results so it’s not that easy to game them. ;)
