I am looking for a plug that can internally link my articles to one another, is there anything at all like this or do I have to do manually ??
Here is one plug-in that does that via the tags. http://fairyfish.com/2008/03/21/wordpress-related-posts-plugin/
I did give it a ago but the time to get it loaded up and working I could have done ten articles manully
You can do it manually, but if there's a lot of pages it can get tedious. Two plugins (free) you might want to look at: yet-another-related-posts-plugin http://seoroi.com/specialty-services/new-seo-plugin-for-wordpress-internal-link-building/ One is automatic and the other let's you specify selected keywords that you can link to a page (sitewide), I've seen people selling a similar script, but this is free if you subscribe in your feedreader.
