As part of the process of assisting one of our clients, Hot Chocolates, in the search engine optimisation of their ecommerce website (designed by 39 Steps and built/maintained by Work Interactive) we suggested that they start a Wordpress blog to assist in adding more content to their site and gaining more inbound links.
We therefore designed and built a Wordpress theme for them which was designed to look like their existing website and we think we did a pretty good job of it! We installed various plugins to assist in the search engine optimisation including the All In One SEO Pack (to produce nice search engine friendly URLs) and the Google Sitemap plugin (to ensure that Google knows about all the posts that make up the blog and thinks HC have a great site with lots of juicy content!)
