I just read an interesting article at Search Engine Journal claiming valid source code helps spiders better index your site. I’ve known about the importance of validating, but I had no idea it affected how your site was indexed.
What is Validation?
According to the W3C:
Validation is a process of checking your documents against a formal Standard, such as those published by the World Wide Web Consortium (W3C) for HTML and XML-derived Web document types, or by the WapForum for WML, etc. It serves a similar purpose to spell checking and proofreading for grammar and syntax, but is much more precise and reliable than any of those processes because it is dealing with precisely-specified machine languages, not with nebulously-defined human natural language.
The article gives a few tips including:
- Use W3C to make sure your site is viewable in major browsers, especially Firefox & Safari
- Test your site on mobile browsers
- Check for all errors in HTML coding and fix them when possible
