When using SEO to get traffic from search engines, finding the right keyword is everything! Your site needs to contain the same words or phrases that your potential customers are typing into search engines right now. Thankfully, there are a variety of tools that can help you find the most profitable keywords to focus on. We have reviewed a few of the most popular for you:

  • Access historical trends starting in 2006, or view current trends from the last 12 months

Though there is less marketing and learning material associated with this tool, it is the only official Google keyword tool. It has gone through a lot of changes in the past year or two – the numbers have been inflated in the past, but the new keyword algorithm should be solving that. The best thing about this tool is how easy it is to get started using it.
