The 27+ Best Marketing Agencies for SEO

Ended soon

Should I hire a marketing agency for search engine optimization (SEO)?

It’s a question entrepreneurs ask me almost daily.

Figuring whether or not you should hire an SEO agency for your business—and which agency to choose—depends on a few factors… including your business requirements, budget and the answer to the question, “is SEO a viable strategy for my business in the first place?”

She’s always askin’ me questions!

Spoiler alert: not every company should hire an SEO agency.

  • For some, it may be too expensive.
  • Some companies should do search engine optimization (SEO) in house.
  • Some companies need content/blog writers, not an SEO agency.
  • And other companies aren’t in verticals that have search engine opportunity. For instance, if you’re selling bacon bandages, there simply aren’t enough people on the web searching for your product to warrant an SEO strategy. You’d be better off focusing your time on other tactics.

The Importance of SEO for Growing Your Business

In the vast sea of marketing tactics, there are lots of ways to get customers and leads on the internet. But the most profitable-from-day-one strategy is SEO. As such, you should probably invest some time at least exploring SEO for your business.

According to a Growth Marketing Pro survey of digital marketers, 78% said that SEO will be more impactful in 2021 than it was in 2020. So you should at least consider investing in SEO.

When SEO is done well, the ROI on time and money spent can be incredibly high. Once you’ve achieved a high rank for keywords that are driving traffic and sales to your site, you’re effectively getting “free” leads.

When Should You Hire a Digital Marketing Agency for SEO Services?

There are a few things you should consider when deciding whether or not to hire a digital marketing agency for help with search engine optimization.

You should hire one if…

1. Your Business Has a Search Engine Opportunity and You’re Looking for Long-Term Success

Again, SEO isn’t a good strategy for every business: some businesses are are perfect candidates for SEO and others just aren’t. If people aren’t Googling what you’re selling, there’s no way you could get organic search volume, even with the best agency in the world.

But if people are Googling what you’re selling or you’re already succeeding with Google Ads, there’s a good chance you should pursue SEO and should consider hiring an agency. It’s also important to understand that SEO will not get you revenue in a week. Unless there’s something easily fixable on your site (like a technical SEO issue), SEO is a long-term game. It will take 60-90 days to begin to see results.

2. You Don’t Have Time to Learn It Yourself

SEO can be time consuming, and if you aren’t comfortable or don’t have time to learn the ins and outs of SEO strategy, plus quickly produce quality SEO blog content, hiring an agency with SEO experts is a good option.

But note that you should maintain at least some in-house brain space for working on SEO internally, so that you can continue to use what you’ve gained from an SEO agency for years to come.

Word to the wise: If you just want to quickly grow your blog with quality content, outsourcing your content creation is a good option as well. 

3. You Have $5k+/month Available in Your Budget

Three thousand dollars a month—or more—is what most reputable SEO marketing agencies charge. Of course, this will vary depending on the size of your company and the exact services you’re interested in.

For medium or large businesses, a standard 1-year project could cost $50k+. It seems like a lot upfront, but when you get your site’s organic search working properly you’ll be able to see continuous ROI. 

4. You’ve vetted an agency and spoke to their client references.

As we discussed, SEO is an investment, and you want to make sure you’re investing in an agency that will give you results. These results mean revenue, not just high rankings. 

You’ll be hard-pressed to find a reputable agency that wants less than a three month commitment. But you should optimize for a short contract where possible. If you’re not getting results in 3-4 months and would like to switch agencies, you should be able to cancel the contract without penalty.

Another important aspect of this is spending some time determining if there is a good culture and relationship match. Companies have different ways of communicating and running their businesses, so it’s important to find a good fit with yours, as well as to get along with a marketing and SEO team you’ll be spending a lot of time with.

5. You’re already investing in some other marketing channels

SEO in a silo doesn’t always work: it’s best when used in combination with PPC advertising, PR, email marketing, social media, and other marketing strategies. At the very least, you should be prepared to capture email leads and send email communications with leads you acquire via SEO.

A technically-sound site, great UI/UX, and well-optimized content is great, but if there aren’t other supporting channels like email marketing, it will take a very long time to see a return on your agency investment. 

When you’re vetting an agency, they should want to understand your other marketing channels. If they don’t ask you for search query reports, your best performing social media posts, and more, there is something wrong. They should be open and excited to collaborate with these other channels to create a data-driven approach for success.

How Do I Pick Out an SEO Marketing Agency?

Okay, so you’ve decided that yes, you want to hire a digital marketing agency to help with SEO! Now you need to determine which SEO company is best for your business.

What Should I Ask the SEO Agency?

There are a few questions you should ask when choosing which SEO company  you want to work with.

1. How Do You Determine ROI?

ROI from organic search will look different for every company, depending on your business model, sales cycle, industry, and goals. But if an agency answers this telling you they can get your website ranked #1 on Google…that’s not the right answer.

Keywords ranking are a good indicator of upcoming success, but if they aren’t followed by more traffic, conversions, and revenue, then it’s not a good measure of ROI. If your potential SEO partner isn’t honest about this and doesn’t understand that you’re looking for scaleable revenue growth, think twice.

2. What SEO tools does your company use?

Are their SEO or marketing tools compatible with the ones that you use? Will you have to download or use new software?This question is important because it will help you determine how compatible your two companies are, as well as what changes you might have to make to ensure a good work flow and success.

It also helps you understand how they gather data, analyze data, and send reports, and how they (and you) can measure success.

I’d expect most agencies to use at least one SEO software tool and Google Analytics at the very least.

3. What communication strategies does your SEO agency use?

Regular, effective communication is essential to SEO success. Google’s algorithm is complex and SEO decisions often involve weighing pros and cons, so it’s important that your SEO partner can clearly and transparently explain their recommendations.

Do they use specific communication platforms? What is their typical response time? Will you have weekly calls, biweekly calls, etc.? All of these questions and more will help you determine a good fit, as well as a create a good working partnership if you move forward with this SEO company.

4. What do you consider the most important ranking SEO factors, and what is your approach to them?

Here, you should be looking for three things:

  1. They should be discussing UX and UI for SEO. While technical SEO and getting your keywords in is great, you need to have a site that users like using. 
  2. They should NOT be mentioning black or gray SEO tactics
  3. A great SEO agency is always evolving. If they haven’t changed their approach and they aren’t mentioning new updates to their best practices, or monitoring search engine changes, they won’t be the best fit.

We also have our own list of answers for the most important ranking aspects of SEO that a digital marketing agency should offer.

What Should the SEO Agency Provide?

In the case of any SEO engagement, the agency should focus on the following ranking factors:

1. A Site Audit

Any reputable SEO company should perform a site audit before making any changes. A site audit inspect your website’s Inspect your website’s optimization, including items such as loading speed, “crawlability,” content issues, meta tags, HTTPS security protocols, internal linking, AMP implementation,  any broken elements, and more.

2. Keyword Ideation and Research

The first (and probably most important) step in ranking for a topic is to select a list of target keywords for your web page or blog post. Keywords are the words someone types into Google when they’re searching for something.

The art of finding those keywords is called keyword research, and without it, you might be ranking for something that no one’s searching for, or trying to rank for a topic already covered by the biggest companies in the world.

Different keywords drive different traffic, and some keywords won’t drive any traffic. SEO companies should know which keywords will work for your business.

3. Content Creation

While you can hire content creation services separately from an SEO service, if you’re investing $3,000 a month, you should be getting optimized, quality content that will help you see a continuous ROI.

Again, ROI isn’t just ranking. There should be more traffic, and higher conversion rates from this traffic.

4. Backlink Building

Backlinks are one of the most important ranking factors because backlinks indicate a website is trusted by others. More quality backlinks = a more reputable website.

Google uses complex, ever-changing algorithms that weigh hundreds of factors so that searchers see the best, most appropriate results for what they’re looking for.
