I would like to offer W3C validation service for your websites and e-commerce systems. I'll analyse and validate all W3C errors of your website and CSS files. W3C validation is a most important task for your web pages and css files.
W3C is an industry standard and that's what the search engines work to. When your web site meets the industry standard, your website will pick up less negative scoring from the search engines than a website that does not comply to W3C. Being W3C compliant won't make a massive difference overnight but if your site is struggling then I recommend it as a must. Let's face it, your site should have been written to be W3C compliant standards anyway!
For Proper SEO of your website, search engines recommend W3C as part of an overall strategy including link building, search engine optimisation and on-going news page interface.
Please note the price is for 1 webpage or css file.
