Note that if I'm working in chunks of 10 sites at a sitting, I suspend site checking given 10 candidates. I then create 10 links and upload the page, making note of where on the page the link can be found. Then I send a message. Work in mention of what I found on the site that I liked, which may mean some editing to make it fit. Where to find the link I have added.
People are busy.
And they are not really interested in your pet project unless there is something in it for them. I point out that I have a link that hopefully is generating more hits right now. I wrap with an invitation to link to my site, but again stress the benefits in doing so. I make no mention of the benefits to me, for they are obvious. I attach an ad-sized icon that draws well, include a brief description of my site as might be appropriate in an annotated listing and the HTML for the link.
