A few common misconceptions here.

You run a tool like copyscape to identify the unique content on your site. You want to get to 95% unique on your own site. The other 5% is your menu, footer, etc.

Ablot of articles today are spun. There is only so many ways 13 tips for roofers can be written. So ppl just take those, use a bot to rewrite them, and put it up. Google is dumb and can’t tell

I have a process where I identify each page and take 5 minutes to prep 5 pages to send to my content writing team. Costs quarter of a penny per word for me and 5 minutes. So basically more than 35 dollars for a nice lengthy article to get on page 1.

There is no such thing as duplicate penalty. Esp for local businesses, shit doesn’t hurt you. Just doesn’t help as much as 95% unique.

If you need help, just PM me.
