Advertisement using text-based hyperlinks.
Text-based ads, although common in email, have been dominated on the Web by their graphical-based counterparts.
Affiliate marketing is one area where text ads have flourished. However, many mainstream advertisers are only beginning to discover the power of text. Google has caused a buzz with its text advertising options, generating a self-proclaimed "click-through rate 4-5 times higher than industry standard for banner ads."
While lacking some of the advantages of graphical ads, text-based ads have some powerful advantages of their own. They download almost instantly and are not affected by ad blocking software.
