Lately, in the past few weeks, we had to configure some wordpress blogs and to design some themes for them, they were a requirement for some clients as a easy-to-use script to complete the content of their page and to improve it's ranking on the internet.
Wordpress is one of the most used tools for blogs and some presentation websites, some people even say that Wordpress rules and the are about right. If you know what you want and you don't need complicated stuff (like online stores with lots and lots of products and online payment or some good looking moving or flying things in flash, CSS or jQuery), than Wordpress is one of the best options for you. It's great for blogging (that's why it's so well known - everybody can create a blog and start writing now) and for pages that has to present several things and that don't need something very expensive. If you know what you want you can have a good result in less than a day: the installation of the script, its configuration and the installation of the plugins, even the theme if you use one of the several existing tools on the market.
For the search engine optimization part, this specific plugin is a great tool. The Wordpress scripts come with some SEO facilities but their beauty is that they can always be improved by using plugins, and everyone can create his/her own plugin and to install in on his/her blog (unless it's on wordpress domain - it's their domain, they make the rules, you can't just any kind of plugins).
They say here about the HeadSpace (the subject of this article) that:
HeadSpace is a powerful all-in-one plugin to manage meta-data and to handle a wide range of SEO tasks. With it you can tag your posts, create custom titles and descriptions that improve your page ranking, change the theme or run disabled plugins on specific pages, and a whole lot more.
I am not going copy to from them the information they are offering about the plugin or to repeat the most important parts of the text, they explain everything you need to know about it and how to start using it.
Consider my recommendation about this excellent script and use it. It's a tool that you (almost) need and if you configure it in the right way it will improve the seo and the rank of your blog for sure.
