Today I found a keyword on Semrush with $5 CPC and 1000 US search. I was really happy and was thinking to make a niche site with that as it was very low competition. But when I searched the same keyword in Adwords, I was just astonished... it has 0 CPC, though the search result is same. How can it have so big difference? Does CPC on Semrush means something different? Another thing, Semrush competition shows 75% for the keyword but when I checked with LTP, it's just 19. I searched manually and found it is really very low competition. Then why Semrush is giving so high result? Please someone help.
