What is a meta search engine?

As good old Wikipedia says:
"A metasearch engine (or search aggregator) is an online Information retrieval tool that uses the data of a web search engine to produce its own results.[1][2] Metasearch engines take input from a user and immediately query search engines for results. Sufficient data is gathered, ranked, and presented to the users."
Put more simply we fine-tune our search engine systems to only gather information from trusted sources that a relevant to your profession. No scam sites,  No misinformation. Only the honest and true facts that you need from your search.
We only add the websites that have been checked and verified by our team, they hold free and readily available information, we do not add paywalled sites. 
searching sometimes throws up a large number of sites that have paid for an SEO company to get them up the rankings. our search engine only indexes information from the sites we approve. Yes, you will get adverts at the top but below is the trusted sites that we have added.
