In order to test various SEO ideas, I have a number of personal sites that experience (sometimes unfortunate) experiments.
The site I tested for category optimization, as you can see from the WordPress.com Stats graph, was a huge success. Once I’ve completed optimizing all the categories the results will be even more impressive.
I’m going to explain what I did with that WordPress site, but please be cautious if you implement these changes on your own site. Make sure that your redirections are working. If you don’t have Google Webmaster Tools set up for the site, do that first so you can keep an eye on pages that don’t redirect properly.
1. Download and install the WP plugins Category Redirect to Post or Page and List Category Posts.
2. Make a new page for the category. Include a keyword header, a couple of paragraphs of introductory content and a photo or other graphic element. You should also create an SEO title and Meta description.
3. Below your content use the shortcode indicated by the List Category Posts plugin. This will create a list of links to all your posts in that category.
4. Go to Admin >> Settings >> Category Redirect. Click Edit under the desired category, then insert the URL of the new category page.
If you decide to give this a try, please let me know how it worked for you.
