Will simple HTML markup lead to better search engine placement?
Monday, June 16th, 2008Here’s a relatively new search engine optimization myth: The simpler a page markup, the more likely the page will be indexed and the higher its rank. This myth seems to have grown out of the movement toward valid XHTML and the separation of web content from the actual page layout itself. Instead of laying out pages using complicated table structures, designers are encouraged to use separate style sheets for a cleaner code and (conceivably) better search engine placement.
We tested two page layouts, each with the same target keyword with similar keyword densities, page titles, etc. to see if there was a difference in 1. WHEN the page was indexed and 2. Which page ranked HIGHER once both pages were listed in the major search engines. The first page used a simple, valid XHTML layout while the content on the second page was nested in nasty, redundant, overly complex HTML tables.
On the first point, WHEN a page was indexed, the complex page came out on top, showing up in Google almost a week before our simple page. Over the following weeks there was some jockeying of position but ultimately the complex page has settled in the top spot over the simple page. So for our Google test, it appears the venerable search engine doesn’t have a problem with complex markup and in fact may prefer it on some level.
Yahoo! had the opposite take on our test and placed the simple page layout on top of the complex page in their search results. If you’ve been keeping up with our test results on this blog you’ll know this isn’t the first or even second time that Google and Yahoo! have disagreed on such a seemingly fundamental point. Based on our limited testing it appears Yahoo! tends to reward many of the “traditional” SEO tricks while Google often yields counter-conventional results.
We have one more search engine ranking test result to share with you, then we’re out. If you have an SEO myth you’d like us to test, leave a comment here and we’ll put one in the hopper for ya.
