Why You Need Keywords

Why You Need Keywords

You need keywords because they are the exact words and phrases people type into Google.

When you know the keywords people use to search for things related to your website or business, you can create pages and content that answer real searches and attract interested visitors.

Google and AI Search platforms find those words in your titles, headings, and content and are more likely to rank your page higher and send traffic to your website.

The same words also power paid search ads, letting you show ads to people already searching for what you offer.

Keywords link your content to the audience seeking it. They form the connection between users, search engines, and your website.

What Is a Keyword Tool?

What Is a Keyword Tool?

A keyword tool is an online tool that uses real, accurate search data to show you the exact words and phrases real people are searching on Google.

You can type a word or phrase into the tool and it will serve up highly related keyword suggestions so you can discover keyword ideas you might never think of on your own.

Our keyword tool also displays important data for each keyword including monthly search volume, keyword difficulty, and cost-per-click (CPC). These metrics enable you to evaluate how popular, competitive, and valuable each keyword is.

By combining keyword suggestions with reliable data, Semrush's Keyword Tool helps you find the right keywords for your website, making it easier for Google and AI search platforms to connect searchers with your site.

    • Keyword Difficulty: A score of how hard it is to rank for the term, with lower scores being easier.

    How to Choose the Right Keywords

    Here's how to choose the right keywords for your website:

    1. Check relevance: Look at the Google search results for each keyword to confirm the results are similar to your website. For example, "running shoes" might be relevant to your website, but "snowshoes" may not be.

    2. Prioritize search volume: Identify keywords that have higher search volumes. Keywords with more monthly searches have potential to drive more traffic.

    3. Identify low-difficulty keywords: From that short-list, focus on keywords with lower difficulty scores. They will be the easiest to rank for. It's often a balance between search volume and keyword difficulty.

    4. Use CPC as a value hint: A higher cost-per-click often signals commercial value, making those keywords strong candidates for revenue-focused pages or ads. A lower CPC may indicate less competition.

    5. Group related keywords: Group close keyword variants and synonyms so one well-structured page can rank for several keywords. If keywords have the same meaning, you should likely use them on the same page.

    6. Map keyword groups to pages: Assign each keyword or keyword group to its own page. Typically, keywords with informational search intent should be targeted with blog posts, and commercial and transactional keywords should be targeted with product or service pages.

    Refine your keywords using these steps and you'll turn the raw data from your keyword research into a focused plan that attracts the right visitors.
