The Wessels Co-op is a Mozilla add-on that adds a Mark to Google Search. It helps users to identify organic search results by marking them with a distinctive icon, making it easier to differentiate between paid and organic search results.
As someone who frequently contributes to a custom search engine using Google Co-op, the Marker button has been a great tool when annotating viewed webpages. However, with Wessels Co-op, users can simply right-click on a link and submit it directly to their Custom Search Engine. This feature comes in particularly handy when annotating online PDF files, as it allows users to focus solely on that one file.
Overall, I found Wessels Co-op to be a helpful software. The only requirement is the use of Firefox, but it's definitely worth giving a try for those needing a more efficient way to contribute to their custom search engine.
