Last week I mentioned one of the useful guides issued by Google, and a lot of you found that interesting, so here's another – probably the most basic one of all, as it happens. Whilst Google's Webmaster Guidelines page is critical to owners of new websites to ensure they don't make big mistakes, it's also a great checklist for your existing site. When you get on to the technical section, don't worry if it goes over your head, but do forward the items to whoever set up and manages your website to get their confirmation that everything's being done correctly. In the Design and Content Guidelines section there are only nine points, so think about every one and how it relates to your website. Google doesn't publish this stuff for fun – if you want to do well in Google, you need to follow its advice.
