If you are looking for an estimation about a Text Link Ads on your blog, Text Link Ads Calculator is an excellent tool to provide you this information. By simply providing your url, website category, number of links to be sold, and the position of ads in your website the calculator can provide you an estimation of how a link on your blog is worth. Patrick Gavin provided more details about factors that the calculator use to evaluate a link :

* Traffic of your website – the lower the Alexa ranking, the higher the price.
* Link popularity of your website – the more links (and more quality links), the higher the price.
* Theme of your website - there is more demand for some themes than others.
* Number of links to be sold – the fewer the number of links on a page, the higher the price.
* Sitewide or single page placement – “sitewide” vs. on a single page of your website (slightly more value given to links that appear sitewide).
* Location on the page - more value when the links are placed in an area where they have the best chance of being clicked.

There is something that I didn't like with this calculator is that it's making this information public, so your competitor know how much for example you can earn. But remember that Text Link Ads have certainly created this tool to attract more publisher, and I know that publisher are attracted when they see money ! What do you think ?
