The Top Free Keyword Selector and Keyword Comparison Tools

Your business depends on keywords so get them right

Keywords are the lifeblood of your website. Visitors search for them online and, hopefully, they're led to your site, at least if you've done your research. You need to draw in traffic, and you need the right kind of traffic. Someone searching the keyword "bass" won't stay at your fishing gear site long if he wants a new guitar. 

So how do you find and select the perfect keywords? Several tools are available to help you along, and they're free. Here are a few ranked according to how well they reported results, how easy they were to use, and how useful the information returned is for search engine optimization, that coveted SEO.

1
NicheBot.com

This free keyword search tool would be worth paying for to access, at least at a reasonable fee. Like other tools, it lists alternative keyword suggestions, but it also breaks things down by major search engines and keyword phrases. The free version only lists the past 100 days, so you might want to use this service in conjunction with KeywordDiscovery.com to get longer-range statistics.

Niche Bot was chosen as the top free resource because it offers a free a thesaurus, keyword ranking, and keyword tracking tools in addition to great keyword search features

It has one drawback. You must enter a "captcha" – those image-based words and jumbled letters you enter to test whether you are human or a robot – for each new search, but you can avoid this by registering for free. More

KeywordDiscovery.com

This free keyword tool pulls information from 100 search engines. It offers web-wide statistics, related keyword searches and a graph that shows seasonal trends. This is an excellent resource for businesses that rely on seasonal income because you can see month-by-month overall popularity of various keyword searches at a glance at any time during the year.

WordTracker Keywords

This tool is a basic but solid free resource. It lists the number of searches made on keywords as well as alternative or related keyword searches. You have to join and sign up for a paid membership to view more than the top 100 related keywords. It's simple to use but it doesn't lead to more comprehensive options. This is a great, user-friendly website for those just starting out in SEO.

GoodleAdWords

Google gets a mention because it remains the most prominent search engine online. Its keyword selector tool doesn't offer a lot of meaningful information, but if you plan to use online advertising, either sponsored links or pay-per-clicks services, it's worth taking a look at how Google ranks the competitiveness of keyword phrases. The more competitive a keyword phrase, the more it costs to advertise using that phrase.

Although it's not necessarily a great tool for SEO, Google's AdWords tool can be useful in helping help you decide what keywords to select, to determine a reasonable price or bid, and to decide which ad service to use. More

Is Free Really Worth It?

There's a lot out there to choose from, and that old adage is true – you get what you pay for. These tools are, for the most part, free. But if your business and livelihood depend on excellent keyword comparison and selection, it might be worth it to pay a modest fee. Many, like the Moz Keyword Explorer, let you try out the tool for 30 days. You're only charged if you like what you find and what to keep going after your free trial. 

Finding the Right Tool

Finding the best keyword selector and keyword comparison tool for your business can be a lot like throwing a fishing line into a pond teeming with fish. You'll definitely get a bite, but in the end the right tool depends on your preferences and needs.
