I quickly generated a Google Custom Search Engine that only searches SEM forums (or should only search SEM forums)...
It is at http://www.seroundtable.com/googlecse.html
Interested in a Firefox / IE7 search engine plugin? Send me an icon and I'll slap it together.
a 16x16 pixel icon that is displayed for the search pulldown
here it is: http://oy-oy.eu/google/cse/data/ser/
I made one for Firefox 2 / IE 7 (OpenSearch) and one for Firefox 1.5.
You can have the OpenSearch one be auto-discovered by including the following code in your head-section:
Code:<link title="SER's SEO + SEM forums" rel="search" type="application/opensearchdescription+xml" href="http://oy-oy.eu/google/cse/data/ser/ser.xml">
Auto-Discover is available in IE7, I'm not sure about Firefox 2 (I think it is)... When you open the page with IE7, it will highlight the search field and when you open the search dropdown, you'll see the search plugin with a small "star" next to it. It's just a small sign of showing that a site has a search-plugin available for it.
