A new tutorial on DevShed today shows how to work with WordPress (a popular PHP-based blogging tool) to improve the search engine optimization (SEO) of the site you have running it.
I ran into an issue on one of my own Wordpress sites the other day, so I decided to share with you my solution. What happened was I added an SEO modification to my site that finds all external links in my page and adds a rel="nofollow" attribute to them. However, I also like to target my external links to new windows, but the target attribute for the "a" tag has been depreciated and will not validate under XHTML strict.
His method of choice turned out to be a Javascript that would run through the links, looking for outbound ones, and dynamically add in the nofollow attribute when it finds one. Complete code is included ot show you how it's done.
