Text Link Scams To Avoid
Wednesday, September 19th, 2007While banner ads are typically tracked by the impression and rotated with other advertisers, you don’t generally expect to get any SEO benefit from them. Straight text links, however, are a different matter. When swapping or purchasing a text link from another website, you should expect and receive a ‘clean’ link directly back to your site.
Unfortunately, there are some unscrupulous people who sometimes perform dirty tricks when placing text links on thier sites. They will swap or sell you a link to your site, but then set up the links so search engines will never see them. You should always be on the lookout for link partners that might double-deal you.
Some of the most common text linking tricks include:
- Using the rel="nofollow" parameter inside hyperlink text. This essentially tells Google this link is not trusted, and should not be considered when calculating the ranking for the site it leads to.
- Using the "noindex" and/or "nofollow" robot meta-tags in the HTML at the top of the page. This effectively prevents search engine spiders from crawling specific pages (and the links on them).
- Using robots.txt to make search engines never visit certain pages. To find this file, go to http://[domainname]/robots.txt
- JavaScript or Flash-generated links. Search engines generally cannot follow these types of links.
- No redirected links that do not directly link to your website. (Ex: http://www.thierwebsite.com/adserver.pl?http://www.yourwebsite.com) Note that redirected links are typically used for banner serving software, so that impressions and click can be tracked.
Pay close attention to those whom you exchange links. Examine how other links are structured on sites you wish to advertise with, and avoid business with those who do not provide what they advertise.
