Как Чистота HTML код воздействию SEO

How clean is your HTML coding? Place your link into the W3C Validator right now to check…

If you have passed the W3C validation then well done! If you have failed then perhaps you don’t need to worry as much as you think… keep reading.

Let’s look at the number of validation errors for the top 10 results in Bing for the keyword “slippers”, we have no experience in “slipper” websites so it will be an un-biased keyword. Also included is Google’s top 10 results for “lava lamp” and Yahoo’s top 10 results for “ice cream”:
Number of validation errors for top 10 ranking websitesPosition Bing Google Yahoo
1 135 151 4
2 54 2 14
3 139 8 887
4 0 6 0
5 22 41 374
6 140 21 2
7 135 319 8
8 1313 3 66
9 87 380 63
10 18 6 55

There are no significant results from this small sample, if W3C validation were a ranking factor then it may only be a very small one. This applies to all the major search engines, Matt Cutts from Google said in one of his Youtube videos that validation was a slippery slope for providing the best search results from content.

If validation were a big ranking factor then many small websites would be at a dis-advantage as they are usually created by people with little knowledge of HTML. If you were searching for “the perfect way to sew on a button” for example then you may not find the golden advice displayed on sewing blog for example.

Also the world’s programmers would have a constant worry that their site didn’t validate, imagine the amount of man hours wasted worldwide every day if validation were a ranking factor!

The job of the web browser is to spot missing tags and try and re-build the website from what’s left intelligently. Most coding errors don’t show up when viewed in advanced web browsers such as FireFox, Chrome and Internet Explorer.

Too much badly written code can confuse web spiders though, this is why it’s best to veer away from multi-table design sites in HTML as one missing tag can ruin an entire site. Using content managed systems such as WordPress or Joomla means that it’s near impossible to break the site layout which is why we recommend it for any client.

So the overall line is that clean HTML code does little (if nothing) to effect your search engine position; if your website looks alright in all the major browsers then it’s probably alright and you can concentrate on optimising it whilst adding valuable content.
