How to Search Google for Synonyms

It’s possible to search Google for synonyms of a word, ie other words that Google thinks has the same meaning. To do this, simply precede the term by a tilde: ~, for example: ~blog will return results for terms such as weblog and blogger as well as those for blog. If you’re only interested in the synonyms then you can exclude the original word in the usual way (i.e. by prefixing a minus sign: - to the term.

So ~blog -blog will return results for weblog, blogger and log but exclude those with the term blog.

This could be useful from a SEO perspective: if you are writing articles which target certain keywords, then it may be useful to target other words which Google associates with those keywords, too.
