I did a competition check with market samurai on keyword "really cheap widgets"
The competition result is reflected in the attached image:

They are huge sites but they do not have on page seo for my keyword, no keyword in title, url, desc, heading. They are targeting the most general terms like widgets, and other keywords related to them. But most are really old domains, thousands of backlinks.
Could this guys be beaten with fewer backlinks but targeted pages with good content, on page seo, etc?
