There are several methods to find synonyms for your search term. You could use a Thesaurus. You could use a tool like the GoogleÂ® Sandbox Tool.
You could use Wordtracker , which will find similar words and help with your keyword research. (To read more about Wordtracker check out my review of it on my SEO Software Reviews page http://websitepromotionbook.com/seo_software_reveiws.html.
Another way to find synonyms is to enter your main keyword into a Search Engine and look at the pages that come up. You can determine which alternate words for your keywords the Search Engine finds, by glancing through some of the results.
