Am currently using my forum signature as backlinks. i was asking my self if all them has to point to the main page or diffrent forums forums like www.gamehaxerz.com/maplestory or just www.gamehaxerz.com it self.
It is necessary to use to different links for each signature to get all the inner pages ranked. Perhaps you cannot need to get backlinks for the inner pages and inturn increase its page rank.
You should use the different kind keyword be your anchor,join in the related forums to recommend your site.
You need to put your internal link url in your forum signature and internal linking for your site can help you in getting inner pages for your site/blog. Another thing try promoting your inner pages as well .
If you're going to be creating multiple backlinks to your site from forum signatures, you should alternate the anchors and the URLs. Simply put, it does you no good to have 3 different anchors pointing to the same URL. Likewise, it makes no sense to use the same anchors and point to different URLs; this creates competition within your own site which is unnecessary. The smart way to create backlinks is to use a different keyword and different URL for each backlink. Then, you've got to maintain consistency with those backlinks to see improvement in the SERPs.
Yes it is very important to vary your anchor text. Don't spam the same keywords as it doesn't look natural and could possibly penalize you.
Don't waste time worrying about forum signature link they don't amount to much and you wont see much of a boost from them in the actual serps. You need to venture on down to the link sales category here on dp and start buying some real links from real websites if you ever hope to rank for anything other than your domain name.
Forum sigs won't benefit your site that much. It can't boost your ranking on search results. But it is good to vary your anchor text, in that way, it would not look spammy/ unnatural.
try to avoid repeating keyword in your signature, include also inner page url as well as natural looks. Also change signature url time to time. It will help you also to promote your inner page.
