One of the most important things is to know, is to avoid doing business with scammers. Any SEO services that promises you first place with a search engine, especially if they promise to do so within a few weeks or months is a scam.
They have no say in the algorithms used by search engines and can not guarantee placement.
The process takes time and is never done immediately.

Stay away from SEO services that will not tell you how they do it, replies with confusing jargon that you do not understand and offers to flood your site with visitors

Better companies will offer regular updates due to the fact that SEO is a process that takes time.

Note whether the SEO company does an in-depth study of your business and website, considers the goal of your website and the location of your target visitors or customers.

Ask for recommendations from previous customers of the company. Ask them if they are satisfied with their investment.
