SEO (search engine optimization) has become a necessary part of any web marketing campaign. Having a high listing on a search engine can mean the difference between being a successful company and one that is floundering to maintain market share. A good SEO services company can help optimize websites and blogs in order to get higher visibility and to maximize viewership among users and potential customers.

What, then, makes an SEO company good? What should a person look for when choosing an SEO company in order to bolster their Internet marketing campaign? There are a few things that everyone should look out for when trying to pick an SEO company to hire.

Here are five signs of a good SEO company:

1. Testimonials from past clients are stellar.

Testimonials are the break and butter of the service industry. If a company is getting a lot of good testimonials, that means that people were satisfied with their services. Most people aren't going to throw out a good testimonial to a company that they didn't believe in.

A lot of companies will either have a page devoted to testimonials from past clients or they will simply throw the testimonials up on their home page. Look at these. Look through them and see if what other people are saying jives with what you are after in an SEO company.

2. Completed projects show improvement.

If you want to hire an SEO company, it is because you want results. If a company is incapable of showing any page ranking improvement, click through improvement, or revenue increases for their clients, then there is no reason to hire them. Talk is cheap. Anyone can say that they did something but not everyone can show it.

3. They have a high search engine ranking.

Practice what you preach. An SEO company should have a high search ranking. That is literally their entire job. If a company can't even manage to get their own page high on the rankings then what makes you think they could do that for you?

4. They set realistic expectations.

Improvement is one thing. Miracles are another. If a company is pitching a line about 1000% improvement immediately, it would pay to be wary about what they can actually do. Nothing comes immediately. Growth is almost universally a slow process. Thus, a person should look for an SEO company that can promise (and deliver) steady growth rather than one that promises an immediately growth explosion.

5. They don't heavily discount their services.

If a business is doing something well, they have no reason why they would need to discount their services more than a little bit. This isn't to say that any company that does this will automatically be bad, but it is a warning sign. Some companies may be trying to build their portfolio with new clients and, thus, are offering a large discount on their services. With that being said: do you want to be the one who takes that risk? You get what you pay for.
