However, since the search engines do not publish their formulas, any statistics provided in the Page Critic are only approximations or estimates based on our research of how the search engines score a page. For additional help, study the statistics in the Page Analysis table. Your goal is to try and make your page have similar statistics to those pages that already rank well. You can do this by comparing your page to specific page, a group of TOP ranking pages, or to the TOP Averages for that engine. The comparison options may be set on the second tab of the Page Critic screen.
Most engines rank pages well that appear within acceptable ranges.
If you exceed their limits, you can actually hurt your ranking, rather than helping it.
