Supporting Terms add context, and make it easier for both users and search engines to know what your page is about.
Supporting Terms help your page to appear in Google when people search for your main keyword.
Can I safely remove Supporting Terms which I think are wrong?
• Check POP's suggested Supporting Terms carefully. If a term is related to something your page is definitely not about, feel free to remove it. We especially recommend removing any competitor brand names.
• Sometimes, words or symbols from other languages can appear in the Supporting Terms, and you should remove these. You can also remove any partial or broken words.
• If there are supporting terms which you are unsure about, it is best to leave them.
Tip: Unexpected supporting terms can sometimes give you good ideas for how to improve the text of your page.
