Most of the time when I blog I am aiming for one particluar phrase, but sometimes I will use a tilde in my search to find what Google thinks are related terms, or synonyms. Google likes a page that contains original text with related terms, so it’s useful to have a peek and see what Google thinks are related terms.
It’s easy to use the Tilde Search Operator - Add “~” before your word (it’s called a tilde).
For instance, here’s the search for “~Hobo” – Without the quotes of course
You immediately see the term Tramp, History of the Book @ Oxford, & Recluse.
It really is 2 second keyword research for Google SEO, ideal for blog posts anyway.
