1. Look at the company's main business

There are several companies doing SEO:

A. Advertising companies: traditional 4A companies, various advertising agencies, few SEO teams and few people, and most SEO businesses are outsourced.

B. Public relations companies: There are generally two ways for such companies to do SEO. One thinks that SEO is equal to public relations press release. If they send more, there will always be a better ranking. A kind of outsourcing.

C.SEM company: Generally, few companies call themselves SEM companies, and common ones call themselves: digital marketing companies, big data marketing companies and advertising companies. Basically all SEM companies have a little SEO business. It is true that there is nothing wrong with SEM/SEO. Generally, more than 80% of this company's business comes from SEM. A small amount of SEO business supplement. Sometimes there are several self-built SEO teams, but they are basically not strong and often outsourced.

D.SEO company: Many SEO companies also have a little SEM business, but if SEM is such a business, it does not account for a high proportion of the main income. SEO business income accounts for more than 70%, there is no doubt that this is an SEO company.

E. website construction company: website construction companies know a little about SEO. This is really superficial, probably equivalent to a little level.

When you go to official website to open the home page of this company, you can see what business is written in the most eye-catching position on the home page, which is basically done by this company. If the business introduction of SEO is only a small piece of the inner page or the inner page. Then it's obviously not an SEO company.
