Page rank and other scores factor in the number of broken links on a webpage, on and off site. Test hyperlink lists by entering the URL you want to test. Results will display all links discovered in a clickable list with any errors highlighted. This is a modified version of the Free PHP link checker, an invaluable tool for anyone who's seo conscious. The typical set of results should be ordered; with local addresses first, then outgoing. Another use for this is finding out just how well competitors are keeping house.
What is a hyperlink? The code is simple if you don't add anything fancy: <a href="http://www.insertyourfavorite.com/">link text/image here</a>. Something more elaborate and SEO that can improve your page rank is adding a "title" which describes the destination. This also aids accessibility enabled browsers to offer choices and navigate for their users audibly. Adding that attribute is easy too, it will form like this <a href="http://www.myfirstlink.com/" title="My First Link">My First Link</a>. Keep it Str8!
