Back in the old days search engines were different creatures. They’ve gradually grown more intelligent, especially to people trying to trick them.

The beast of the link exchange came about because everyone wants to rank higher. The number and quality of incoming links your website has is a very important part of search engine’s ranking algorithm. So naturally millions of website owners across the world went about inflating their incoming link count by participating in link exchanges. Often you’d get an email like this in your inbox:

Dear Webmaster,

My name is Wild Earth Adventures, and I run the web site Wild Earth Adventures: http://www.wildearth-adventures.com/

I recently found your site http://www.cairnsconnect.com and am very interested in exchanging links. I’ve gone ahead and posted a link to your site, on this page:

http://www.wildearth-adventures.com/linkmachine/resources/links_adventure_travel.html

As you know, reciprocal linking benefits both of us by raising our search rankings and generating more traffic to both of our sites. Please post a link to my site as follows:

Title: Wild Earth Adventures
URL: http://www.wildearth-adventures.com/
Description: Adventure Holidays Canada, Wilderness tours and Eco tours

This email is generic, impersonal and somewhat irrelevent to my business. There is an industry theme, travel. So how could it hurt to exchange links with them?

• A link is an endorsement
  By linking to this company on your website you’re saying to your customers that you stand by this company and support it. Consider how embarrassing it might be if this company also links to dodgy sites, or worse, pornographic websites. Not a good look for your business.
• You might end up in a ‘bad neighbourhood’
  The search engines will trust your site less if you appear to be linking to many websites, especially if they’re not related to your business. Having a link to a website who has dodgy outgoing links cause cause your website to receive a penalty from the search engines.
• Customers don’t like it
  Your potential customers come to your website to find out information about you, your products and services. By sending them off to various links of an unrelated nature indicates you don’t really know how to support your product with complementary businesses.

Years ago search engines decided they’d had enough of reciprocal linking monkeys, and removed the value attached to a reciprocal link in terms of your rankings. They now reward you when someone links to your website, without you needing to link back. That’s a real endorsement.
