I am looking at a keyword phrase that may have some potential:
"how to polish trinkets at home"
Exact google search per month US = 4,400 (Google) or 5,400 (not sure if US or global - SerpiQ)
CPC = $4.70 (SerpiQ)
Google Results for - "how to polish trinkets at home" (exact phrase in quotes) = 101,000
Exact match domain all major tld's taken.. possibility's postfix with "tips" , "hq" , "1", etc?
Market Samurai analysis:
Too big to paste here but basically..
"Avg competition index for top results" = 40
This is certainly not an obscure niche so should be plenty of products to promote and plr content
