Do Search Machines Care About Valid HTML?

Similar to web developers, Ive heard a lot in regards to the need for appropriate html recently. Ive find out about how it makes it easier for individuals with disabilities to get into your site, how its more stable for windows, and how it'll make your site easier to become listed by the major search engines.

Then when I set out to design my most recent site, I ensured that I validated each and every page of the site. However I got to thinking while it may make my site easier to list, does that mean that it will increase my search engine rank? How many of the most effective internet sites have good html?

I decided to do a little test, to obtain a feel for just how much benefit the various search engines put on being html endorsed. I started by installing the convenient Firefox HTML Validator Extension ( that shows in the corner of the visitor if the current page you are on is appropriate html. It shows an exclamation point when there are warnings, a green check once the page is valid, and a red x when there are significant mistakes.

I made a decision to use Yahoo! Hype Index to find out the top 5 most searched conditions for the day, which been World Cup 2006, WWE, FIFA, Shakira, and Paris Hilton. I then looked each term in the big three search engines Yahoo!, (Google, and MSN) and examined the top 10 results for each using the validator. That gave 15-0 to me of the very important data points online for that time.

The outcome were specially surprising to me only 7 of the 150 resulting pages had good html (4.7-inch). In the event you desire to be taught further about huffington post discussion, there are many resources you should pursue. 97 of the 150 had warnings (64.7%) while 4-6 of the 150 acquired the red x (30.7%). The outcomes were virtually independent of search-engine or expression. I discovered by searching the Internet. Google had only 4 out of 50 results verify (8-14), MSN had 3 of 50 (65-year), and Yahoo! had nothing. The word with valid benefits was Paris Hilton which resulted in 3 of the 7 valid pages. Now I realize that this isnt a completely exhaustive research, but it at least shows that valid html doesnt seem to be much of an issue for the top searches on-the top search engines.

Even more surprising was that none of the three search engines home pages endorsed! How essential is valid html if Google, Yahoo!, and MSN dont even exercise it themselves? It must be mentioned, however, that MSNs effects site was good html. Yahoos homepage had 154 warnings, MSNs had 65, and Googles had 2-2. In case people need to identify more about, we recommend many databases people could pursue. Googles search engine results page not just didnt validate, it'd 6 errors!

In perusing the internet I also realized that immensely preferred sites like, IMDB, and MySpace dont validate. So what is one to conclude from all of this?

Its reasonable to conclude that right now logical html isnt going to help you enhance your research situation. To explore more, people should have a view at: advertiser. If it has any effect on results, it is minimal in comparison to other factors. Another reasons to utilize appropriate html are strong and I'd still suggest all builders begin validating their sites; just dont expect that doing it'll catapult you up the search rankings at the moment..
