So beyond ranking your site well, what makes this engine cool? :)
SearchMe has a pretty cool interface that rotates snapshots of webpages on a carousel format. The search results are pretty accurate too. Searchme allows users to share searchme's snapshot of your web page and share the snapshot with other people.
However the snapshot is not necessarily the best page of your site. Their snapshots appear to be ancient. So you could lose traffic if it's showing an outdated or inappropriate page.
