Came across this on YouTube today, an introduction to Wordpress blogging and comment moderating. Definitely worth a watch if you’re interested in starting a blog of your own - which I’d recommend, especially as part of a larger site. So long as a site’s blog is regularly updated it can really help the overall SEO, providing the search engines with fresh content to gobble up, and if the blog is on topic it’ll usually also provide opportunities for targetted cross linking. For example if your site deals with doll’s houses and you write a blog on the subject of miniature baths, you could link “miniature baths” through to a relevant page. I’ve even seen plugins that will automatically link mentions of specific keywords through to the relevant page on the site, making it even easier to take advantage of blog posting.
