I'm a firm believer that adhering to Web Standards helps to improve the search engine friendliness of your website. The on-page content is better organized, making it easier to index individual pages There's an improved use of semantic elements such as anchor text and headings, and Navigation is more likely to be text-based which assists spiders in crawling the site Does anyone else have any thoughts on the impact of web standards on SEO?
If your site is W3C compliant at w3c.org I have heard the spiders crawl it easier, so I ensure all my pages are easy to read!
