This is the first step for any new advertising program and usually the hardest. TLA carefully selects which sites can be added to their network so if your blog is brand new, then you should wait at least 6 months before applying. If decide to apply anyways and get denied, I’d send them an email and ask to be manually added.
Their automatic approval system runs some basic calculations on your site (blog age, page rank, popularity, etc) which determine whether you’ll be approved. I’ve actually been rejected for a couple of my blogs but when I emailed them, they manually approved them. Sign up for Text Link Ads and start selling links today!
