If you want Google to know when to show and optimize your page, you have to optimize for a solution and the topic so that the person searching will benefit from the page they land on.
Yes, keywords make a page understandable for a search engine, and if it is the phrase and jargon your customers are using, it will be relatable.
Being relatable can increase conversions because you’re speaking your customer’s language. But don’t stress over the keyword.
If you’re going to focus on something, the best bet, if you want traffic and conversions, is to hone in on the intent of the searcher.
When you do this, the keyword begins to appear naturally throughout the page – and in ways an actual customer would be using it.
