Google's ranking algorithm consists of more than 200 factors, and failing to address each one can make it impossible to reach the top of the results.  

Because this is so complicated, it's essential to choose the right SEO company for your local business.  Let's look at what services SEO companies provide, what to consider when selecting a company, and then finally, the top SEO companies in the market right now.

SEO Services

SEO agencies offer a wealth of services to help businesses and other website owners improve their search engine visibility.  SEO services should not only increase visibility, but lead to greater conversion rates as well.

Standard SEO services include:

  • Keyword Research
  • Competitor Analysis
  • On-Page Optimization
  • Off-Page Optimization
  • Content Marketing
  • Conversion Optimization
  • Link Building
  • Social Media Marketing
  • Google My Business Creation and Management

Many companies also offer additional services, such as website design and reputation management.

What to Look for When Hiring an SEO Company

If you were to Google "SEO company" you'd end up with almost endless results.  Many of those results are from companies trying to get your business.  Unfortunately, many of these companies will gladly take your money without providing the results you need to succeed.

With that in mind, let's go over the factors to consider when hiring an SEO company.


The top SEO companies understand the importance of gathering reviews, so they work hard to get them.  Don't discount a company that doesn't have a perfect five-star rating, though – having some negative reviews can increase credibility.

Most importantly, notice how the company responds to negative reviews.  This will give you an idea of how they will manage your reputation strategy – if the company responds poorly to negative reviews, you might want to look elsewhere.

Past Clients

Checking in with past clients is an excellent way to vet a potential SEO company.  Top companies are happy to share portfolios and testimonials from previous clients.  If the company has worked with a large brand before, that can be a good sign, as larger clients tend to have stricter processes around their hiring.

Case Studies

Review case studies when looking for top SEO companies.  Case studies allow you to see the company's strategies and techniques in action.  Good case studies will reveal measurable results that show how the SEO campaign helped the client reach their goals.

Employee Social Media Accounts

You can learn so much about a company by analyzing employee social media accounts.  Head to Facebook, Twitter, and other social media sites and take a look at the profiles of some of the people at the agency. You may find some insights here that you wouldn't otherwise find looking only at their more "official" channels.
