if i submit my link in 200 forums.. is my display name (or user name) same for every forums is good or different name is Good? or you can say if i add same display name (or user name) is google consider as spam?
Hi, Username doesn't do any harm on your site, but anchor text will do. As much as possible try to variate your anchor text so it will look natural to google.
If I were you, I wouldn't go for those kind of links as they're of low quality. Go for a few high quality instead. Saves you lots of time, believe me!
I do not think it matters whether the links are displayed by the same poster or different posters... as long as the forum and the posts are relevant to your niche. Regards, RightMan
I think the best username is your brand or product name, because everyone see your username can see your product name and this makes more people know your brand or product.
what is best link structure for forums my site url | my site subpage1 url | my site subpage2 url or my site url | other1 site url | other2 site url or both are fine?
user name and signature is both different matter, Google see signature and your posts, not use name, yes you are right, some forum admin don't allow spamming use name but they ask for real name.
is forums signature allow 2 signature can i use my onsite url in 4 time with different anchor text? or i have to use 4 different site in signature?
Poster name does not matter SE's will only look at where the link is going and the keywords and other words surrounding it
Any dofollow links will help you but since those links are most likely norank it will have little effect on your serp rank. A PR 0 page would probably trump all your effort.
