Find out if valid HTML coding has SEO benefits
How to prove HTML Validation provides SEO benefits?
So we do we gather enough insight into the benefits of valid HTML coding?
We've decided to begin by building 2 similar, niche market websites. However, as we all are aware, SEO has so many variables we need to ensure the experiment remains in a somewhat 'controlled' environment.
Our SEO research team has provided us with 5 strict criteria for our 'controlled environment' that must be met.
1) Exact-Match Domains
Our first step is to register an exact-match domain name (for instance, nichemarket1.com.au and nichemarket2.com.au).
Our domains names should included our niche target keywords in order to speed up the SEO indexing and ranking process.
2) Website Hosting
At first, we wanted to give the impression that both sites were completely unrelated and so we were leaning towards using 2 different but similar structured website hosts based in the US.
After numerous discussions, we have decided to proceed with both of the new websites to be hosted on the same web hosting server.
3) PHP, OpenSource
Both websites must use the same common PHP opensource platform. A custom template may or may not be applied however both sites will be quite similar in appearance and presentation.
Once both websites have been setup and completed, we will proceed to optimise the sites with our standard SEO package including 30 x directory submissions. The SEO performed on both sites will be identical in nature in order to highlight the ranking differences between valid HTML coding and invalid HTML coding.
5) HTML Coding
One website will have the HTML coding optimised while the other site will have the stock standard coding which includes at least 20 to 35 invalid HTML errors.
Both sites will be checked and tested using the W3C's HTML Validation service;
We'll keep you posted on our progress once the websites have been completed and we'll upload the ranking reports over the next 3 months so that you keep updated on our experiment and are able to come to your own conclusion...
Is valid HTML coding is beneficial to your website's SEO rankings and/or Google PageRank...?
