Here is an example of a letter you could write to other webmasters to invite them to swap links with you.

eMail Subject:
Trade Links with us and get more hits!

eMail Body Text

Hi,
I visited your excellent website and would like to suggest we exchange links.

As you may know, the more links you have coming back to your web site from other sites of a similar theme, the better your ranking will be on the top search engines and directories and the more visitors you will get to your site.

We do not compete with each other, so we thought that it would be mutually beneficial to trade links.

If you would like to accept our offer, please reply to this email with your confirmation and the details you would like for your link. Sorry no images.

Here are the details we would like you to put on your links page:

URL : http://www.yourdomain.com

TITLE : You can use the title you have in your index page meta tags here

DESCRIPTION : Put a short description of your website here

OUR LOGO : ( Insert your logo image here )
If you would like to use an image, please copy this logo to your hard drive and addit to your links page

Thanks
Your Name
