How did you build this list of the top SEO companies?

We didn’t just pick random SEO companies out of a hat to create this list. We evaluated several factors when compiling this list of the top SEO firms worldwide, including:

• Deliverables: Top SEO companies offer everything their clients need to improve their SEO performance, so we looked at the breadth of services companies offer. In the end, the top SEO companies on this list provide turnkey SEO solutions.
• Testimonials and reviews: Past client experiences speak volumes for an agency. When compiling this list of the top SEO companies in the world, we paid close attention to reviews and testimonials across multiple platforms.
• Success factors: How agencies measure success is especially important. Do they look exclusively at rankings, or do they also look at key performance indicators (KPIs), like leads and conversions, that drive bottom-line value?
• Results: Finally, we looked at the work agencies have done in the past. Do they bring in the results they promise their prospective clients, or do they fall short? By examining case studies, we evaluated agencies’ SEO expertise and service. 

What is an SEO company?

An SEO company offers search engine optimization (SEO) services to help clients improve their performance and visibility on search engines like Google. The best SEO companies offer a variety of SEO services that align with each client’s individual needs and goals, helping them drive valuable traffic (and ultimately revenue) to their business.

What kinds of services do SEO companies provide?

SEO companies offer a wide variety of services, all of which are related to helping clients improve their website’s search engine rankings. These include services like:

• Keyword research
• SEO audits
• Competitor analyses
• Local SEO
• SEO strategy development and implementation
• And more!

Additionally, some SEO agencies also offer digital marketing services like pay-per-click (PPC) advertising, social media marketing and management, and web design services.

How much do services from top SEO companies cost?

Typically, SEO services cost anywhere from $2500 to $10,000+ per month. Where you fall in this price range will depend on your budget, the services you’re looking for, and the SEO agency itself.

Every SEO agency’s pricing will vary based on factors like expertise, and some agencies won’t even post their prices on their websites for anyone to see. Instead, users must contact them for a quote, which can be inconvenient when you’re in the early stages of searching for an SEO partner.

Are the top SEO companies worth the money?

Yes, the top SEO firms are almost always worth the money.

Price is a significant factor when companies look to outsource their digital marketing, but too often, we’ve seen clients partner with cheap SEO agencies and end up with more problems than they started with.

Enlisting the help of cheap SEO agencies can damage your company’s overall reputation online and offline.

Enlisting the help of cheap SEO agencies can damage your company’s overall reputation, especially if the agency uses black-hat SEO tactics. Black-hat SEO strategies are frowned upon by search engine algorithms, and sites that use them are typically ranked lower for being untrustworthy.

Working with a cheap SEO agency can also negatively impact your:

• Search rankings
• SEO results
• Return on investment (ROI)
• And more

On the other hand, reputable agencies avoid sketchy optimization tactics. Top SEO agencies provide you with the peace of mind that you’re working with a partner who wants to see your business succeed and is going to help you achieve your SEO goals the right way.
