Yoast SEO is one of the most popular WordPress plugins in the world, and for good reason. It brings professional-grade optimization tools into a friendly interface that anyone can use. Yet a surprising number of site owners install it and never fully enable or understand its keyword features. If you have ever stared at the focus keyphrase box wondering what to type or why the traffic light stays orange, this guide will walk you through enabling and using keywords in Yoast the right way.

Make Sure Yoast Is Installed and Active
Before you can enable keywords, confirm the plugin is running. From your WordPress dashboard, go to Plugins and check that Yoast SEO is installed and activated. If it is not there, navigate to Plugins, click Add New, search for Yoast SEO, install it, and activate. Once active, you will see a new Yoast SEO menu item in your sidebar and a Yoast meta box beneath the editor on every post and page.
Finding the Focus Keyphrase Field
Open any post or page in the editor and scroll below the content area until you find the Yoast SEO section. At the top you will see a field labeled Focus keyphrase. This is where keywords are enabled at the content level. Type the primary keyword or phrase you want that page to rank for. As soon as you enter a keyphrase, Yoast begins analyzing your content and displays a color-coded assessment showing how well the page is optimized for that term.
Understanding the Analysis Signals
Once your keyphrase is entered, Yoast provides two analyses: SEO analysis and readability analysis. The SEO analysis checks whether your keyphrase appears in critical places such as the title, the introduction, at least one subheading, the URL slug, the meta description, and image alt text. Each item gets a red, orange, or green indicator. The goal is to turn as many signals green as possible without forcing the keyword unnaturally. Remember that these signals are guidelines, not absolute rules, so prioritize a natural reading experience for humans.
Enabling Related and Additional Keyphrases
The free version of Yoast supports a single focus keyphrase per page, but Yoast Premium unlocks additional and related keyphrases. This is valuable because most pages naturally rank for several related terms. To enable them, upgrade to Premium, then look for the Add related keyphrase button beneath the focus keyphrase field. Adding related terms lets you optimize one page for a small cluster of connected searches, which reflects how real people phrase queries in different ways.
Configuring the Cornerstone Content Feature
Yoast also lets you flag your most important pages as cornerstone content. In the Yoast meta box, open the settings and toggle the cornerstone content switch. This tells Yoast to apply stricter analysis to your flagship pages and helps you build a strong internal linking structure that points authority toward them. Enabling this feature is a smart way to signal which keyword-focused pages matter most to your overall strategy.
Common Mistakes to Avoid
Many users misuse Yoast by chasing an all-green score at the expense of quality. Do not repeat your keyphrase so often that the writing becomes robotic. Avoid using the exact same focus keyphrase on multiple pages, as this creates keyword cannibalization where your own pages compete against each other. Finally, do not ignore the readability analysis, because search engines increasingly reward content that is easy to read and genuinely useful.
Beyond Yoast: Building a Complete Strategy
Enabling keywords in Yoast is only the on-page piece of a much larger puzzle. To truly compete, you need keyword research, content planning, technical health, and link building working together. A broader digital marketing program ties these elements into a coherent plan, ensuring your carefully optimized pages actually get discovered and shared. Yoast tells you whether a page is optimized, but strategy decides which pages to create in the first place.
Final Thoughts
Enabling keywords in Yoast SEO is simple once you know where to look: install the plugin, enter a focus keyphrase, and use the analysis to refine each page. The real skill lies in choosing the right keywords and writing content that satisfies both readers and search engines. Treat Yoast as a helpful assistant rather than a strict judge, and pair it with a thoughtful strategy for the best long-term results.
