Hello, friends I have exchange links with 2 website and I see where they add my website link at, but for some reason google and all the other backlink checker is not showing them. It have been about 2 or 3 weeks now.
Google for one will only show a selection of your websites backlinks - they will not list all those that have been crawled. WebDev
Try to open that page with your link on it with google-bot user-agent. If u see it so it's all okay. If not - the webmaster could use cloaking.
