With all that’s going on these days in the search engine arena, I believe it’s particularly important to try to optimize sites not just for Google but for other search engines as well (which are, of course, Bing and Yahoo). The good thing is that SEO for all these search engines is rather similar. However, there are some factors that make a difference.
I have conducted a search online to find analysis of SEO for the various search engines. I found several excellent documents. Here’s what I found:
SeoWizz.net has done a conclusive analysis between Bing and Google SEO optimization. My summary is this:
- Google greatly values incoming links, particularly diversity, more than Bing does.
- Bing favors older domains.
- Bing favors links from pages that include your keywords in their title.
Inchoo.net adds that:
- Bing assigns more importance to the title tag than Google does.
- Bing favors older domains (similar conclusion to SeoWizz).
- Bing likes more incoming links than Google (which in fact, contradicts SeoWizz). It is possible to resolve this contradiction by not just looking at the number of backlinks but also factoring link diversity – an element Inchoo did not take into consideration (I believe).
SeoWizz also analyzed the difference between Yahoo and Google.
- Google takes into consideration meta tags whereas Yahoo does not.
- Google places more weight on incoming links than Yahoo does.
- Google assigns more importance to domain age than Yahoo (an interesting observation, considering Bing is even more extreme in that respect).
- SeoWizz’s conclusion is that Google is better at treating a site as a whole (i.e. a collection of pages) than Yahoo, which treats every page individually.
This image shows rankings for several of my websites using various key phrases, for both Google (G), Yahoo (Y) and Bing (B) with a broad search. This was generated using Market Samurai, an excellent keyword research tool that can be used for a huge range of tasks, including keyword research, ranking, monetization, publishing content. Definitely the best tool in its category. It examines the top 200 results, and is sorted according to Google’s results.
When I look into my own site statistics, it becomes obvious the majority of my websites/phrases rank better on Google than either Bing or Yahoo. So the results are generally consistent with the reported above observations. That being said, my own experience – which was not mentioned by either of the above websites – is that Google assigns a lot of value to the site URL, much more than both Yahoo and Bing.
Therefore, I believe the rankings of my websites for the various search engines are currently the way they are because:
First, most of my sites are new to relatively new – thus, they would not be favored by Bing but would be liked by Google.
Second, I believe most of my sites have a rather diverse link portfolio and quite a lot of links. Again, liked by Google.
Third, most of my highly ranked websites are using a domain name that is heavily searched (found using keyword research tools) whereas the sites that are not well ranked are not.
Even this domain, Industry Review, is ranked #5 for Google for the broad key phrase ‘industry review’! And I have not done any backlinking or SEO. I think this heavily supports my conclusion.
That being said, there are the occasional anomalies. I can only explain those by certain Google slaps. These are actually sites that did very well at first, but suddenly drifted into the 200+ position (and have slowly improved over time).
It is going to be interesting to see what the new Binghoo engine is going to bring us, and how the various differences are going to be resolved. Personally, I am quite excited, as I see more opportunities than perils.
