    How Keyword Research Tools Work

    Keyword research tools refine your SEO strategy and digital marketing efforts by suggesting keyword variations and related keywords. For example, let’s you’re targeting the seed keywords “coffee”, “espresso”, and “cappuccino” for your cafe’s SEO. If you plug them into the tool, you’ll get keyword variations like “coffee near me”, “macchiato”, and “americano”.

    Since all those additional keywords are coffee-related, you can consider targeting those keywords as well to strengthen your SEO strategy. While you can perform the keyword research process manually, these tools help you create more effective keyword strategies faster.

    What Makes A Great Keyword Research Tool? 

    With many keyword tools available online, you might find it tough to choose which one will work for you. Here are four things that keyword research tools must provide to be truly great: 

    • Data completeness: A tool for keyword research doesn’t just need to provide a list of keyword ideas. It also needs to get into details about them, which means they must include the keyword’s traffic, ranking position, and SERP analysis. 
    • Reliable data sources: Knowing where your keyword data comes from is also an important factor. At the very least, your tool for keyword research must take data from major search engines like Google.
    • Ease of use: Keyword research tools don’t have to take years to master. The best keyword research tool should be easy to understand and allow any business owner to optimize and rank for their chosen keywords without too much training.
    • Affordability: SEO software isn’t cheap. That’s why we’ve scoured the market for the most affordable SEO tools for small-to-medium businesses.

    What Are The Benefits Of Using Keyword Research Tools

    The right use of keywords significantly impacts organic page rank in search engines, especially when most people don’t look past the first page of search results. 

    Here are three things you can do with keyword tools: 

    • Perform Competitive Keyword Analysis: A keyword research tool helps you get a feel for the competition. By plugging in a competitor’s website, you’ll see the keywords it’s targeting. These competitive analysis results help you decide whether to target different keywords or attempt to rank higher for the same target keyword.
    • Make SEO Development Easier: Ranking high on SERPs isn’t easy. However, keyword tools can do some of the heavy lifting for you by finding relevant keywords people often type into their search box. From there, you can build the right SEO strategy to take the top spot on SERPs.
    • Find High-Value Keyword Ideas Faster: Shorter and more popular keywords are typically harder to rank for. Keyword planner tools help you find long-tail keywords, or longer and more specific phrases that make your content unique and easier to rank for compared to a broad keyword. Capitalizing on these untapped keywords is one of the best ways for your site to rank higher.
