Although website tools and tests aren’t always 100% accurate they can provide a quick way of finding out some genuinely useful information about how well a site is built and it’s effectiveness in search engines.

These are 3 of my personal favourites -

SEO Analyzer

SEO Analyzer tests how well a site has been built by taking into account factors including whether a page has a semantic structure, download time and use of obsolete & deprecated HTML. These are combined to give a score out of 100, although it is implied that this tool rates the SEO of a site, I think it’s a more useful indicator of if a site has been built to web standards.

Web Page Analyzer

Web Page Analyzer gives a report on the amount of time it would take for your website to load on different connection speeds. It also lists all images, code and scripts used on a page by size.

My only criticism of this tool is that it’s a few years old now and some of the advice given seems to reflect this - “Consider reducing total page size to less than 30K” I think a more realistic page size to aim for is around 100k.

Page Strength

Page Strength gives an overview of the visibility and importance of a page in search engines. It does this by ranking a page on factors such as links from sites including DMOZ & Technorati and domain name visibility in Google, these are combined (along with other factors) to give a web page a score out of 10 along with a brief summary.
