Hi. I work as a link builder for an SEO agency. We have a client who works with a lot of vendors, and I'm trying to see if I can garner a link from those vendors back to my client's site.
However, the vendors tend to link using banner logos. I was taught that Google cannot read these "images". But when you thinki about it, a banner has an image URL as well as a location URL.
So I right-clicked on one of the banner logos, copied link location, opened up the view source page, Control F'd to find the link, pasted into the find box, and there it was.
So that tells me the location URL within a Banner Logo is indexible and can be crawled by the search engines.
