A tool that measures a site’s relative popularity on the web using metrics that are used by standard search engines.

Pros: For any given website (or URL) SitePopularity measures the most important ranking criteria such as its PageRank value, Alexa Traffic Rank, or DMOZ listing. These are standard measures that are used in standard search engines (for example Google uses PageRank) and therefore indicates the relative popularity of a web-site. It also takes into account the actual results (number of pages returned for the given website when it is queried on the search engine) from a number of search engines including Google, Yahoo, and AltaVista. The combination of ranking criteria and actual results is used to indicate the site’s popularity, and this can be used to compare it with a number of different websites. The fact that each result (PageRank, number of Yahoo search results etc) is indicated separately means that a user can decide to compare rank by a specific measure.

The interface is simple and visually easy to gather information from. This is a good tool to start measuring the initial popularity for a website or blog that you setup.

Cons: There is some overkill in that Google search uses PageRank so ranking taking both into account seems to be biasing the results partially in Google searches favor. Either one of these measures would have been enough. It is not clear who exactly would benefit from this kind of information in the long term. User’s beware that there is always some subjectivity in any search measure or metric, although if there is widespread agreement (across search engines) that usually indicates good results.

Overall: 4 stars. It works well and gives a good sense of a web site’s popularity. However, it is of limited use in the sense that not many people have a need for this, not even experts.
