This strategy is to add FAQs to your pages. FAQs are a great way to naturally ad targeted keywords to your content on your website. This is because FAQs allow you to include relevant questions without making your content look spammy. Think about common questions your customers ask and then answer them on your site.
A great way to find FAQs for your website is to use a free Chrome Extension GMB Everywhere. Open up the extension and type in your service in the search bar and then click on the AI tool tab. Then select Q&A Generator. You can see GMB Everywhere will generate a bunch of FAQs.
You can use the generated FAQs and insert keywords in response and put them on your website. This will help Google pick up your page for all the different keywords and help in ranking your page on top.
