For SEO strategies to work, you must first figure out which keywords you want to use to optimize your search engine hits for. In many instances, you can probably guess what keywords will drive traffic to your site. However, for proper SEO keyword choices, we can be smarter than that. There are a few free SEO keyword tools that exist to help us make the decisions on which keywords to use for SEO.
The first SEO keyword tool to mention is from the source of the search engine, Google External Keyword Tool. By putting in a general search term, this SEO keyword tool will give you the relative advertiser competition and also the average search volumes, all for the google search engine. This can give you some hints as to which keywords are going to be the most important for driving more traffic to your website. The competition follows the money, so going into an area with high competition isn't necessarily a bad thing, if you are hoping to make any money by targetted ads.
The second SEO keyword tool I will mention is another tool to tell what the relative number of searches are for particular keywords, but this tool isn't specific to the google search engine. The tool is provided by Wordtracker. This tool shows the comparitive search volume. Again, this is great for figuring out which keywords are better than others when you are choosing to optimize.
This next tool was built to help tell which keywords that people search for might lead to a product purchase. This is called commercial intent, and the tool is made by Microsoft AdCenter Labs. Keywords with commercial intent have a higher chance of leading to a sale on your site for whatever product you are selling. This might be kind of fuzzy to you, so let me show you a basic example. Let me throw a couple of search terms at you. The first one is "free popcorn", and the second one is "popcorn". This is an obvious example, but as you can guess, the search for "free popcorn" obviously isn't looking to pay for anything. However the search for "popcorn" could be looking for special popcorn kernels, or salt, or popcorn poppers. If I put those words into the commercial intent tool, I get a probability of 0.59375 for "popcorn", but only 0.31117 for "free popcorn". I would not include "free popcorn" as a keyword you optimize for, "popcorn" will be much better. Or even better, how about "popcorn popper" (0.81871) or even better, "popcorn salt" (0.89281).
