What is keyword research?

Keyword research finds the words people use when they look for information on a topic, and how often those words are searched on Google and Bing. It supports both paid and organic search campaigns. The aim is to find terms that fit your business and offer, with healthy search traffic.

What are keywords?

Keywords are the terms that best capture what a page is about. A keyword is the search term you want that page to rank for. It is often a phrase, not a single word.

For example, a flower delivery site might target "flowers gift delivery". Ask yourself what you want to rank for, what people would type, and how you would sum up the page in a few words.

Why does keyword research matter?

Search engines read the words on a page to work out what it covers. The right terms bring the audience you want. The wrong ones bring visitors who are looking for something else.

Focus on your audience first. Put yourself in their shoes and use the words they use.

How do you do keyword research?

Build a simple spreadsheet of general categories, such as product categories or themes your customers care about. Keep it short. Five to ten topics is a good number.

2. Brainstorm the keywords your customers might use

For each topic, list the terms and phrases a customer might type to find information, products or services. If you have Google Analytics or Google Search Console, check the organic search section to see which terms already bring people to your site. This is a brainstorm, not your final list.

Search a phrase on Google and look at the related searches near the bottom of the page. Click one and check the suggestions on the next page. You can also enter a phrase into Google's Keyword Planner or a paid tool.

4. Check how strong each keyword is

Keyword Planner or paid SEO tools show how a term performs. Note these points:

  • The phrase should match what people are looking for.
  • Search volume should be big enough to matter.
  • Check how competitive the term is. Paid tools show competition for ads and for organic search.

Look for terms with high search volume and lower organic competition. Also look for related terms you may have missed.

5. Judge where you can compete

If big brands hold the first page for a term, switch to less competitive long-tail keywords (longer, more specific phrases). Look at what ranks at the top of the search results for terms you want and add long-tail options to your list.

6. Check search intent

Search intent is what the person wants when they type a query. Look at what already ranks and what it offers. A person who is only browsing may click once and leave. A person ready to buy is more likely to convert if you give them a product page.

Record the intent behind each keyword in your spreadsheet and check it before you create content.

Which tools can help?

  • Ubersuggest
  • Semrush
  • Ahrefs
  • Moz
  • Backlinko

Besides search volume, compare cost per click (CPC), difficulty to rank and estimated visits.

What comes after keyword research?

Keyword research is the starting point of an SEO strategy. Each blog post, article and product description should be more useful, easier to read and more complete than competing pages, and the site should be easy to navigate and work on mobile.
