I just want to promote the jewelry shopping website.BUt someone said it is not useful to post here in the seo forums like digitalpoint .Because it is not relevant to the jewelry shopping.so i am wondering whether or not it is useful to keywords ranking by posting here with signature for seo purpose.Thanks for your help.
It will help you in SEO but the keyword targetted forums are given more importance than any other forums. and you get targetted traffic and thats the need of your business. Here peoples look for website related problems they are not going to buy any jewellerys, but if you join a forum (find one by "keyword"+forum) that is related to your market. you will get traffic and sales. However if you are only looking for SEO yes it will help you by posting as many link as possbile (but only on authority websites like DP, WF etc.) -Ashish Patel affiliate marketer & blogger
