Similar to how a social media aggregator collects social media posts from a number of different social networks, a search aggregator collects the search results for a query from multiple different search engines. They are useful tools for getting a wider breadth of search results, but there is so much more to these search engines.

What Is the Difference Between a Search Aggregator and a Metasearch Engine?

Sometimes the terms search engine aggregator and metasearch engine are used interchangeably, which is understandable because they are similar in many ways. In fact, a search aggregator is actually a specific type of metasearch engine, which gathers results from multiple search engines simultaneously usually using RSS search results.

According to Wikipedia, search aggregators are an increasingly popular way to take advantage of the power of multiple search engines with a flexibility not seen in traditional metasearch engines. To the end-user, a search aggregator may appear to be just a customizable search engine and the use of RSS may be completely hidden. However, the presence of RSS is directly responsible for the existence of search aggregators and a critical component in the behind-the-scenes technology.

What Search Aggregators and Metasearch Engines Are Out There?

While many search aggregators and metasearch engines have either become bankrupt under the crushing weight of Google or were brought up by Google (or one of its many competitors), there are still plenty of uniquely wonderful search aggregators and metasearch engines out there.
