1. AdWord & SEO Keyword Permutation Generator

3. Google Correlate

An underrated keyword research tool that comes straight from Google. Google Correlate is really simple: It shows you keywords that tend to get searched for together. For example, let’s say you pop “gluten free” into the tool. Google Correlate tells you that people searching for “gluten free” also search for “cheese gluten free” and “flour gluten free”. Very cool.

4. Google Keyword Planner

The Google Keyword Planner is the only keyword tool that gives you data straight from the horse’s mouth.

Cool feature: The GKP tells you how likely someone searching for that keyword will buy something from you. How? Look at the “competition” and “estimated bid” columns. If the “competition” and “estimated bid” are high, you probably have a keyword that converts well.

5. Google Trends

We always check Google Trends before pulling the trigger on a keyword. Why? Because I want to know whether or not my keyword is getting more (or less) popular. If you skip this step you risk optimizing your page around a dying keyword.

Cool Feature: Scroll down to the bottom of the page and check out “Queries”. These are related keywords that you can pop into the GKP to see if they’re a good fit.

6. GrepWords

A solid, reasonably priced keyword research tool with an excellent question scraper.

Cool Feature: “Divergent” shows you what time of the year certain keywords tend to spike. For example, if you want to see which gift card keywords tend to perk up around Christmas, GrepWords will show it to you. Ditto with Halloween and keywords related to “costumes”.

7. Keyword Combiner

Keyword Combiner is basically designed for Adwords. But it’s a great tool to find keywords that you can use for SEO as well. Just pop in a bunch of different keywords and the tool will mash them all together. Then upload them to the GKP to check their search volume. Helpful.

10. Keyword Snatcher

This tool probably gives you more keyword ideas than any other tool on the market. Why? Because it finds keywords from a bunch of different places, like Ebay, Amazon and even Yahoo. In fact, the last seed keyword I put into it (“paleo diet”) generated 15,000 keywords! The one downside to this tool is that it doesn’t show you how many people search for the keywords that it spits out. So you need to manually upload the keyword list into the GKP to get search volume info.

SECockpit is probably most advanced keyword research tool on the market. Yes, you enter a seed keyword and get suggestions like any other tool. But SECockpit can do so much more than list out a list of related keywords. It can spit out low competition keywords. It can show you keywords that get a minimum CPC in Adwords. It can even show you keywords that have YouTube, Ebay or Amazon results on the first page. Cool Feature: SECockpit scrapes the “Searches similar to…” from the bottom of Google’s search results.

17. Seed Keywords

Let’s face it: Most people enter seed keywords into the Google Keyword Planner that they pluck out of thin air. But with this free SEO tool you can find out what people actually type into search boxes. How? Just create a scenario and ask people what they would search for in that situation. For example, I created a scenario “How would you search for a hotel in Paris?”. You can see the results in the screenshot below. You can even export the list as a CSV file.
