When you send a website owner a link request, you should remember that every website owner has to pay domain registration and web hosting expenses and is under no obligation to provide a free link to your website. Most link exchange requests are a waste of time , with very low conversion rates. Bloggers usually have Akismet or some other spam detection software installed on their blog to detect and block spam comments. In such a case, it is advisable to purchase text link advertising by paying the website owner a small monthly, quarterly or year fee. You can also purchase a permanent text link on a specific blog or a number of blogs by paying a one time fee. Along with the text link ad, you can include a description of your website. Unlike PPC advertising, there is no limitation on the number of words in the advertisement. After you pay the one time fee, you do not have to pay anything additional to get more visitors to your website, which is a major advantage compared to Pay Per Click advertising, where you have to pay for every click on your advertisement.
