I am looking around for a solution that will allow me to check on and change broken and/or expired affiliate links on my wordpress sites. Is there anything out there that can make this job easier?
There are several search and replace plugins available, all have different strengths and features. Search 'replace' in the plugin directory, you'll find something. DD
Since it's Wordpress if you now the anchor text you could use a plugin like seo smart links when creating the links that way you could just replace the URL. I'm not sure if it'll work now since the links are already created though. http://wordpress.org/extend/plugins/seo-automatic-links/
I actually use gooldencan.com to create php pages for a variety of affilates instead that way it is automated and this is not an issue
Next time route your affiliate links through a tracking system, then you can update links to an offer all at once.
I use viral url plug in...whenever your affiliate links change, all you have to do is log into your viral url account and change the affiliate links, this will automatically make your links now live.
