Top Two Google Factors Defined. Implications for Search Engine Optimisation Discussed

Oct. 5, 2011 - PRLog -- The top factor in the Google algorithm is the PageRank of the HomePage of the website (HPR – G-Factor-1). The second factor is a hidden adjustment boost to the PageRank of HomePages that are competing for a keyword (G-Factor-2).

The PageRanks (PRs) of the top 10 webpages for numerous competitive keywords and their corresponding HPRs were recorded on a spreadsheet. HomePage PageRank was clearly the top factor as far as Google was concerned but it did not explain a few exceptions occurring with some medium difficulty keywords.

Most of the top page positioned webpages with PR0 for medium keyword difficulty were themselves HomePages. Google has been all about "authority" and website popularity as indicated by links from other websites and is assuming that the HomePage of a website has that website's greatest authority. The conclusion is that Google is providing a boost in effective PageRank to Homepages when they are competing for a keyword: This is the second factor in the Google algorithm - G-Factor 2.

Many SEO experts suggest that PageRank is irrelevant in SEO because there are many examples of webpages with PR0 that are on the top page of Google for highly competitive keywords. Their observations have been confirmed but all the internal web pages they quote with PR0 have HomePageRanks of 4 or more.

Confirming the top two factors on Google.
To test the validity of the top two factors as explained above, search for any keyword on Google with either Internet Explorer or Firefox with the Google toolbar active. Check the PageRank of any of the webpages on the top Google search engine results page (SERP) and also the corresponding HomePage PageRank. If one of the top webpages is a HomePage with PR less than 5, add the G-Factor 2 boost so that the effective HPR becomes 5.

From a practical point of view, a newly indexed website has HPR0 for all the indexed pages. If the HomePage is appropriately optimised for a keyword, it will have a chance of reaching the top page on Google only if the averaged adjusted HomePage PageRank keyword difficulty (HPR-KD) for that keyword is less than 4.4. HPR-KD for a keyword is calculated by averaging the HPRs, including the G-Factor 2 adjustment boost, of the webpages on the top Google SERP. Internal pages on a newly indexed website will not be able to reach the top Google SERP for any worthwhile keywords as their associated HPR is 0.

In time, as naturally acquired links from other websites are accumulated, the HPR of websites will increase and keywords of increasing HPR-KDs will come into range. Websites should focus on keywords that are currently in range for top positioning on the SERPs. This will allow the website to be found and for new links to be acquired naturally. A website will receive more targeted traffic from the search engines if it is on the top SERPs for keywords that are in range but with relatively little traffic than if it is invisible on the SERPs for keywords with more attractive search volumes.
