I'm seeing a few people on here with sigs like this: www.xyz.tld - Bob's World of Crap If you want to SEO you signature link, you want the description of the site to be the text for the link, not just after the link: Bob's World of Crap Otherwise, the only people who will know it's Bob's World of Crap are humans who read the actual sig. Google wouldn't know that.
yeah best way would be to put the name in the hyperlink like you have and then the url beside it if you want people to remember seeing the URL so like: Bob's World of Crap - (site url) where the name is linked like you have
After a site gets indexed through a forum signature, does the link still have to remain in the forum signature (in order to continue being indexed)?
Once you're indexed, you're in the system. But you want to keep the links to maintain good backlinks.
sig links dont have much valueas normal but they are still very good they get us huge traffic if we have lot of posts in forums
Signature link have a big value. it helped me a lot when I first launched the site. Through this links I guess Google can find my site easily.
