hey guys, i have a good niche which is supposed to get good monthly traffic. good quality original content. wordpress, unique template. i did article submission, social bookmarking, directory submission, rss, blog commenting, and STILL nothing. nada. no traffic. no visits. i have 30 sites like these. they've all been up since march-april. so, should i just keep doing this? at what point should i call it quits? its a huge strain on my budget.
