I add my site in different forum with signature. But when I check my backlink in site popularity only a few link were present from the different sites. Suppose in a form I created 50 post with signature but only 10 back link were present from that forum.
it takes time for search engines to show your backlinks. google takes lot longer than others. besides, just because you have a signature link on a post doesn;t mean that you will get a backlink form it. not all the threads get indexed and even if it does, search engines might not be able to index a single thread page and follow all the links on that thread then assign backlinks to everyone on a single crawl. if it is a popular thread and stays on the front page for a while, the your chances are better
maybe yahoo is the best way to find them, but it doesn't say that google gives any value for those links.
ur generate 50 links with ur post but if pages are not indexed by search engine that will not show when check back lnk in google or yahoo
Google will shows only some post from the same site. But if you check it through webmaster tool can see all Back links. And also some time all the psot will not indexed by google. So this also one possibility of not showing BL
Generally Google dose not show all back links. It’s better to search on Yahoo go there and search you URL https://siteexplorer.search.yahoo.com/ Thanks
Comments on sticky threads are very good if want to be sure the thread gets indexed by search engines.
You can try with Yahoo search because yahoo consider nofollow and dofollow. So you get better result with yahoo back links.
