Finding the best SEO companies isn’t easy. Sure, you could search “best SEO company” and click the top Google results, but that’s not guaranteed to get you what you’re looking for.

A lot of those top results are long lists and review sites. And some of them aren’t as clear-cut as their makers would have you believe. That’s why I sorted through 7 of the top lists of the best SEO companies to find which is easiest to use, the most informational, the most credible, etc., to help you find a provider that’s right for you.

You can sort SEO professionals by sponsored listings, verified companies, Clutch rank, number of reviews, review rating, and company name. And you can even get more granular, filtering by average rate, size, and more.

When you click through a company profile, you’ll get even more information about the provider, like their focus areas, industry, services, and even a portfolio of their work.

Digital marketing services to look for in an SEO company

Every SEO agency needs a set of marketing solutions that enable them to improve your online presence through search. As you explore your options — whether they’re an SEO consultant, freelancer, or agency — here are some services you should look for:

Link building:

This SEO strategy uses techniques like social media marketing and guest blogging to increase your number of high-quality backlinks. Backlinks are links from other websites to yours, and the more high-quality backlinks you have, the more valuable Google perceives your website to be.

Pay per click (PPC)

Search engine optimization is a method of inbound marketing. It focuses on unpaid methods of attracting traffic through search engines. But, it’s only one half of the umbrella category search engine marketing (SEM). The other half refers to digital advertising tactics that fall under the category term “pay per click.” These have to do with generating traffic through paid advertisements placed on search engine results pages. If you have any plans of someday using paid advertising in your marketing strategy, it’s a good idea to look for an SEO agency that offers both PPC and SEO services.

Local SEO

Some companies who engage in SEO do most of their business in a specific area. For these small businesses, local SEO is a must-have. This strategy helps storefronts get found when someone does a Google search for local products and services, like “plumber in Phoenix, AZ,” or “law firm in Dallas, TX,” or “hardware store near me.”

Keyword research

When you want to figure out how people are finding your business in Google and Bing, you do what’s called “keyword research.” It commonly involves examining SERPs with SEO tools — like Moz, Google Search Console, Ahrefs, Clearscope, etc.  — to uncover search terms that may lead to potential customers. Once you know these keywords, you can run content marketing campaigns to meet the search intent of your target audience.

The three crucial factors of keyword research.

Content marketing

You can’t have SEO without content creation. This work comes after keyword research when you create web pages featuring your newly discovered target keywords. With the help of a marketing team that includes strategists and content creators, you can use content marketing to position yourself on SERPs with articles, blog posts, videos, and more, to earn website traffic from search engines.

Technical SEO

Most SEO strategies that fall under on-page and off-page SEO don’t require technical knowledge to do well. But there’s a third category of SEO techniques, known as “technical SEO,” that require more specialized knowledge to complete. These are tactics that improve the infrastructure of your site, and they involve things like robots.txt files, canonical tags for duplicate pages, HTML sitemaps, and even page speed adjustments. Good SEO specialists know how to use these technical strategies among many others, to make sure your pages work well for both users and search engines.

The difference between technical and non-technical SEO.

Web design

More people access the web via mobile than desktop, and Google’s goal is to provide the best user experience. That’s why website design is so key to SEO now. Today, top SEO firms can oversee the web development of mobile-first websites, so they work well across all device types. Since Google’s introduction of mobile-first indexing, the mobile site design has become a priority for businesses that want to rank well.

How to evaluate the best SEO companies

You have the lists, but how do you choose from them? What should you look for as you evaluate potential SEO services? Here’s a quick checklist:

  • Know your own business needs and goals. Being able to express your own business metrics and goals will help an agency figure out if they can help you. Some marketing firms excel in different areas and industries, and if they know what you need from them, they’re in a better position to tell you if they can offer it. You might think you only need SEO, but then find out that conversion optimization, email marketing, and lead generation services could help, too. If that’s the case you may want to consider a full-service internet marketing agency as opposed to a niche marketing company like an SEO firm.
  • Find someone with experience in your industry/niche/size. SEO isn’t exactly the same from industry to industry. The principles are, but the strategy changes. For example, SEO for an e-commerce brand on Shopify won’t be the same as SEO for a local real estate agent. The same is true from small to medium and larger businesses. The details of SEO aren’t the same. Look for a firm that has a staff of SEO experts in your industry, niche, and size.
  • Look for a history of success. There are signals you can look for to evaluate an agency’s work history. The most important are testimonials from past clients to show a positive track record over years of experience; case studies of the firm’s work methods; and examples of SEO campaigns that they’ve used to help businesses similar to yours. Remember to look outside of the agency’s website for reviews (like on Clutch, for example), since they’re more likely to be honest and unfiltered.
  • Take advantage of an SEO audit. Most SEO teams offer a free consultation or SEO audit to prove they can find and solve issues with your website. They’ll evaluate your web pages and tell you how the agency would go about fixing them. Taking advantage of this is like taking your car to the mechanic. Listen to what they have to say, but get a second and third opinion to see which firm seems the most capable and trustworthy.
  • Don’t be afraid to ask questions. Some business owners don’t ask many questions about a firm’s SEO services because they’re afraid of looking ignorant. But understanding what you’re paying for is a major part of deciding which firm to go with. Don’t be afraid to ask questions. This is also a great way to test an agency’s temperament. If they’re frustrated with you after only a few questions about their services, it’s a red flag. They’re not who you want to be in business with long-term.

Get a free SEO audit

SEO services can be expensive, and it’s important to trust an agency before you enter into a long-term contract with them. Don’t just look for proof that they know what they’re doing, ask for it, too. The best marketing agency/client relationships start from a place of open communication.
