Hello, My blog site is about off-the-beaten-track destinations in Iran. I am redoing my entire site for SEO for the first time. Yoast plugin wants me to pick a "focus keyphrase" for each post.

I want to attract people who are interested in travel to Iran.

So my obvious keyphrases are "travel to Iran" or "tour of Iran" or "trip to Iran" or "touring Iran" or similar phrases.

But picking these SAME keyphrases over and over for each page, does that make sense?

Yoast wants me to stuff the keyphrase in my title so all my titles are starting to look the same, starting or ending with "travel to Iran" or something similar.

But NOT picking these same keyphrases doesn't feel right either. The site is about travel to Iran. Some pages are not easy to keyword in just a couple of words. Article on "How to pick a tour of Iran that fits your personality?" --- what in the world would be the keyphrase for such an article? (Remember, I have to fit it the keyphrase in my title, meta description and first graph of the article.)
