Did you get a random email from some SEO expert saying that your website can't be found on the first page of Google or your website is full of errors. Express caution with spam emails. Some of these emails are from Organized Crime in India targeting businesses that don't understand how SEO works. They target businesses that are desperate for results and are driven by saving money. That's the recipe for getting ripped off.  Some people learn a hard lesson after sending money to start the project and never hear back. It's a total gamble when you trust an email from a spam bot. Why not support local businesses instead.
