About The Results
an example search result
How moreofit Searches
Each website has a unique tag signature -- a set of words that users have described the website as. Moreofit searches for websites that have similar tag signatures and displays the results.
1: Similarity
A site's "similarity" is determined by how well its tag signature matches the tag signature that is being searched for. A 100% match means that it has the exact same tags in the exact same order, while a 0% match means it has no tags in common.
2: Popularity
The popularity of a website is, well, pretty much self explanatory.
3: Tag Signature
The tag signatures show how a site is described. The deeper the color of the tag, the more frequently the website is tagged as this. Tags underlined blue denote a tag that is in common with the search's tag signature.
