Discovering Keywords
Top down approach
What are the general topics, services, and products you’re featuring on your website? Enter them into a keyword research tool, which generates similar and related keywords. This helps tell you what keywords to target and what new pages to create.
For example, if you type in “wedding,” you might find keywords like “wedding cakes,” “wedding DJs,” and “wedding photographers.”
Bottom up approach
What specific pages do you envision on your website? What is unique about your business? Enter specific phrases into keyword research tools and search engines, with the goal of identifying popular keywords that match up with your site’s focus. Tie your ideas to viable keyword opportunities.
Competitor research
Look at websites that are currently ranking for keywords you want to target. Use SEO tools to see a list of their keywords. Peruse their site to get ideas for other pages and keyword targets. Compare your pages to theirs. There’s no more fundamental SEO strategy than to create pages that are better than the competition.
Google suggestions and related searches
Using Google itself is an easy way to gather keyword ideas. When you start typing into Google’s search bar, you’ll likely see suggested queries as you type. And at the bottom of a search results page, Google usually shows a list of related queries. Pay attention to both of these; they might surface keywords you hadn’t found yet.
Innovative approaches
Over time, digital marketers have come up with creative ways of discovering keywords. Peruse Wikipedia articles relating to your website’s topic to see how the article is sectioned off. Find questions people have asked on Quora, Reddit, forums, and social media. Automated tools help a lot, but human ingenuity is a powerful tool as well.
