3. Choose your price
Only two steps
1. Paste the line below into a news or blog post on a site you run and publish it. A new post or an addition to an old post — both are fine.
Just paste the whole line — the URL becomes a link automatically (no HTML is needed). The wording is only a sample: feel free to rewrite it to fit your site (any wording passes as long as the link is there). Placing it on another page of your site, or embedding one of our diagrams, also counts (we find it automatically).
2. Enter the URL of the site where you posted it. The top page URL of the site or blog is enough.
4. Start your placement
