My site's been online since 2004, and I've been actively seeking links the whole time. In the last year or two, though, it's become much harder. I'm trying to get links to interior pages to help their rankings, but I feel like I've hit a wall.
I have links in my signature on forums, but I've reached the limit on the forums for the number of links.
I have links on all sorts of quality sites in my niche, but they're not willing to list my site twice.
I've done all sorts of articles, but the payback from that is decreasing, as many here already know.
I've done blog posts where I can, but the link value to me would seem short-lived.
The niche I'm in doesn't lend itself to the younger audiences found on Digg or Stumbleupon, nor does the content of my site.
Mine is an informational site in a sports-related niche. The information is pages of photos and spec's on models of niche-related widgets. I also have a small online store selling related widgets.
I've been reading the Link Development forum for years, and it seems to me I've exhausted the ideas I've seen here that would work for my site.
Have any of you hit a wall with links? Do you just keep getting more from small sites, blogs, etc, or do you do something radically different?
