Things To Consider When Choosing A Keyword Research Tool

Competitive Analysis

Being given a list of your top rivals and visiting their websites to discover what keywords they're focusing on is extremely important. To help determine the keywords they're targeting, read the text and look at the metatags. Examining your competitors' keywords can not only reveal what you may be overlooking, but it will also help you expand your range of possibilities. Make sure the keyword research tool you choose offers this capability.

Long-Tail Keywords

Long tail keywords basically include keywords that are 3 words or more in lenght. You should always give priority to the tool that provides suggestions for these keywords.

These keywords tend to have lesser competition, bring in relevant visitors, and there is a good chance of getting ranked up by including these keywords.

Location-Based Keywords

Location-based searches are another important thing to consider when optimising for the proper keywords. Users of search engines typically add their location in their search while seeking contractors and services in their region. As a result, "best plumbing services" changes to "best plumbing services in Boston".

If you just operate in one geo-location, you should consider adding location-based keywords to all of your pages, as visitors from other places won't benefit you much. If your company has many locations, it's also a good idea to build a distinct web page for each one so that your brand is visible when consumers search for specific places. Your keyword research tool should provide you with such analytics.


We believe these 12 tools will assist you in identifying keywords and phrases that will aid in the development of great content and marketing campaigns. You can try out each of these tools to figure out which one works for you the best.
