Why you should use a focus keyphrase only once
Your focus keyphrase is the keyword(s) you want your post or page to rank for. If you’re particularly eager to rank for a specific keyword, you’ll probably be tempted to optimize many articles for that keyphrase. But that’s not what a focus keyphrase is for, and you should only use it once. But why? What if you desperately want to rank for that particular keyphrase? Don’t worry, we’ll tell you about it in this post.
Are you seeing an orange or red light for the previously used keyphrase check in Yoast SEO? Here’s what this check does and how to turn that light green.
Don’t compete with your own articles
Why shouldn’t you use your focus keyphrase more than once? Because you don’t want to compete with yourself for a position at Google. This phenomenon is also called keyword cannibalization. By optimizing two articles for the same focus keyphrase, you’re telling Google two things: both are suitable for people searching for that keyphrase, and both should appear in the search results.
While having two articles rank for the same keyphrase isn’t necessarily impossible, you’ll find that it’s still very hard. Your site needs a lot of authority, especially if you want your two articles to appear in the top ten search results for the same query.
What if you already rank with one article?
If one of your articles already ranks, you may have enough authority to try to rank with a second one. However, if you’re not already ranking for a focus keyword, never use it more than once. Instead, update and improve your original article. Then write another post that covers a slight variation of the keyword.
Ranking for your desired keyphrase
What do you do if you want to rank for a particular keyphrase? Imagine you’re starting an online store for horse feed. You probably want to rank for [horse feed]. Seeing as you’re just starting, that’ll be pretty hard. You might think you need to optimize all your posts for [horse feed], but as we’ve just seen, that’s definitely not the case.
So what should you do? Your keyword research will give you ideas about other terms to target.
Content for your blog
If you have a blog, which we advise you to have, you could write a high-quality, all-encompassingg cornerstone article about all the different aspects of feeding your horse well. Next, you should optimize this article for the term [feeding your horse] using our Yoast SEO plugin, and mark it as cornerstone content in our plugin.

You’ll need to write many posts covering a different aspect of your main term. For instance, you could write and optimize articles for focus keyphrases like [best type of hay for your horse], [pasture management], [feeding thin horses], [feeding sport horses], and so on. These are called long-tail keywords.
If you link from these long-taill articles to your head term article about [horse feed], you’ll be telling Google which of your articles is the most important. This will help you with ranking your most valuable article. At the same time, you’llll also be attracting traffic for those long-tail articles.
Content for your store
So, what if you have many product pages for a horse feed? Let’s say you have a big assortment: feeds for thin horses, fat horses, sport horses, etc. Should you optimize all your product pages with feeds for thin horses for [feeds for thin horses]? No, because in this case, it makes more sense to optimize your category page for this term instead of all your individual product pages.
Can you use a focus keyphrase more than once?
Of course, you can, but in most cases, it’s not a good strategy for achieving great rankings for a keyphrase. If you want to rank for a keyphrase, dive a bit deeper into a topic. See what questions people have. Could you write long-tail articles about those questions?
Also, look at the other search results. Who is your competition, and what do they show? How can you distinguish yourself from them? When you’ve written your content, embed your articles in a solid site structure to increase your chance of ranking.
What does the previously used keyphrase check in Yoast SEO do?
One of the assessments of the SEO analysis in Yoast SEO is the previously used focus keyphrase check. This assessment checks if words from your keyphrase were previously used in another keyphrase for other posts or pages on your site. If you’ve used it for another post or page, you’ll get a red traffic light. Why? Because you should optimize only one page for a specific keyphrase.

What to do if you have already used your keyphrase more than once?
If you click on the link next to the red bullet, it will guide you to the other article you’ve written about it. Take a good look at the articles. Check which one performs best in the search engines or gets the most traffic. Keep that article, or merge the best aspects of both articles into the one that ranks highest. The free Yoast Duplicate post rewrite and republish feature can help you with that.
If you just found out you’re aiming for the same keyword or keyphrase with multiple articles, it might pay off to audit your content to find possible cannibalization issues. Fortunately, we have a guide to finding and fixing keyword cannibalism on your website.
