I own a website coded by PHP language. When I check html errors at the website: validator.w3c.com, I found above 200 errors. I don't know whether these errors have much effects in doing SEO.
some people believe that site validation effects your SEO score. I personally think it may well have a very small impact as generally your site will be considered "better" on a technical level. This of course does not mean that your actual content will be any good, and that's why i think Google puts only a minimal emphasis on this.
Does not make any effect on SEO.HTML errors does not make any effect on SERP.its better to fix them for better usability
You are wrong. eg: What will say google when u have the same color for text and background? Do u think that google doesn't care...
Does not make any effect on SEO.HTML errors does not make any effect on SERP.its better You should fix all errors.
just out of interest - the ones who are stating "does not effect SEO" as a FACT - how many of you have personally tested this? i'd be very keen to know where you're getting this information!
i will suggest you to solve all the errors as it will be easy for google to update your site and it will also be easy to visit it again...and you can also use W3c standards and thats a great benefit...
