Online Research: Keywords & Filters

A search engine reads the words you type and tries to match them to billions of pages. Strong keywords act like a clear address — they tell the engine exactly which neighborhood to look in. Weak keywords are like saying "somewhere in the city": you will get an answer, but it probably will not be the one you want.
