I am working on an E-commerce website on WooCommerce+WordPress platform. I am using Yoast SEO plugin for SEO.
The Yoast SEO plugin recommends you that you can use only one focus keyword on only one page on the entire site. (May be because it confuses the google to bring what page to show when that focus keyword is searched).
So my question is should I use that one focus keyword on product category page or on the product page itself?
Also in that product category there are atleast 4 products (which differ slightly from each other) who will have the same focus keyword.
So in such a case what should I do? Am I missing something? I am new to SEO. I'll be really grateful if someone could help me figure this out. Thanks in advance.
