Text Link Ads Review
Here’s my quick analysis on what I like and dislike about TLA. It’s certainly not perfect, but a beginning and hopefully goog enough for a short review:
* Pros:
Best and largest selection of publishers
Large advertiser base
Relevant In-content Links
Privacy protected marketplace
Fast payouts
Script or manual link placement
* Cons:
Strong competition for good links
Confusing site usability

]]>Traditional Text Link Brokers Companies like TextLinkAds give you access to 10,000’s of link sources.
The main benefit with such networks is the ease with which you can place ads across a number of websites. The biggest downside with such networks is that since they are large and well known they are targets for search engineers who aim to minimize the ability of paid links to influence their rankings.
Quasi-Link Networks Some ad networks like BuySellAds are not traditional link networks by trade, but may provide some of the ease of buying benefits that you get from traditional text link ads.
Site Reviews Companies like ReviewMe, SponsoredReviews, and Blogsvertise allow you to buy product and/or site reviews from blogs in your field. Some of these networks use rel=nofollow on outbound links, but some of them allow you to get direct links.
Direct Link Purchases Purchasing links directly from publishers is the most time consuming link building strategy on the market, but if you are creative with how and where you look you can find clean link sources that are off the SEO map, which stand a good chance of passing link authority to your site for a long time to come.
Buying Links Through Promotions Buying links indirectly through promotion in some cases can yield cheaper and higher quality links than you can typically buy directly, though it takes some creativity and industry knowledge to create promotions that will take off. Some promotional attempts may fall flat on their face, especially when you are new to the field. But as you gain experience you are more likely to succeed with promotions.
