Omniscient Digital is an organic growth agency that drives attributable pipeline and revenue for B2B brands.

While we specialize in B2B, particularly SaaS, we’ve helped startups scale up from their seed round to millions in revenue, and we’ve also worked with Fortune 500 companies to unlock new growth opportunities. 

Our key strength is we build SEO strategies and programs that index on a business’s unique strengths and opportunities, and we aim our programs towards revenue growth (not merely increasing search rankings). Look at our case studies. They have dollar signs on them. 

We’re also not a full service digital agency; we specialize in organic. 

As an SEO agency, we’ll drive strategy, build analytics and reporting tools, monitor and proactively update and fix bugs, and build backlinks. We’ve also got a content production that can scale to 100s of editorial pages a month (and more if we’re talking programmatic SEO).

What Criteria to Look for in the Best SEO Agency

What matters when choosing an SEO agency?

Scrutinize these five dimensions:

  1. Specialization and competencies
  2. Track record and reputation
  3. Industry focus
  4. Team
  5. Cost

Specialization and competencies

Call me crazy, but I like a specialized agency.

That’s just my preference. Other firms want an agency that can do it all – paid, SEO, social, web development, etc.

While some agencies can perform well across multiple domains, I think it’s pretty hard to scale and maintain quality everywhere.

Of course, it’s also not ideal to have to manage 12 different agencies. So what’s the sweet spot? 

Well, that’s going to be determined by you and your executive team.

Personally, I think an SEO agency that can build strategy, has analytical resources for attribution, and can actually drive throughput and execute on page creation, technical updates, and link building is the winner. 

Really, everyone should be able to conduct SEO audits and do keyword research. But do you need social media management or web development to be housed in the same agency? Maybe, but likely not. 

Bonus points if they can scale to ambitious levels. Because, after all, who wants to mess around in the kiddie pool? SEO success follows the Matthew Principle, so go for the gold!

Track record and reputation

“The best predictor of future behavior is past behavior”

No one actually knows who said that, but it’s mostly true. I mean, it’s not true in financial investing, but it is definitely true in hiring talent. 

If, for instance, I’m hiring an SEO strategist, I want to see that they have DONE things. Moved the needle. That they’re a driver, not a passenger. 

Same is true for SEO firms. 

Ideally, they have both public facing case studies (which you should take with a grain of salt) as well as a good reputation in “dark social” (whatever that means nowadays).

Basically, if you ask a bunch of people you trust about them, the overall sentiment should be…good.

Here’s a hint: ask to talk to their current or former clients as a reference check. If they don’t allow it, that’s a huge red flag. 

Industry focus

I think this is ultimately much less important than some people do, but it sometimes helps to have experience in a specific industry.

Where I think it matters is in ecommerce vs local vs B2B SEO. The sales cycles, website development, and digital marketing strategy differs a lot here.

Where it doesn’t matter is if the agency has specific experience in your incredibly narrow niche of cloud CDP solutions for cannabis brands. 

Who cares? The people on your account, their talent and expertise, matters much more than the serendipitous happenstance of an agency having worked with your competitors in the past. 

Team

The team is really the most important thing. 

First, who are the founders? What’s their background? No matter what, the ideology and temperament of the founders will drip down, to some level, to the rest of the team.

Second, are you going to work with a talented team or are you getting the B-squad? You can ask who will be on your account, by the way.

We specifically ordain a strategist onto a new account based on their experience and inclination in the space and the specific problems to solve. E.g. If we’re going to work with a web3 client, we’ll place a strategist who has worked in that space, or has at least worked on similar problems (in this case, likely blue ocean SEO strategy). 

Ask this question, too: what happens if we want to change the team assigned to our account? Also, will the same team be working on our account the whole time?

IMO, it’s best to have a consistent team, but also have the option to swap out a writer or team member if they aren’t working out. 

Team is the one thing you can’t mess with if you want to win.

Cost

Finally, you have to take cost into account. Budget isn’t endless. 

Two points here: avoid too high of cost (obviously), but also avoid too low of cost. 

There ain’t no such thing as free lunch in SEO, and if the cost is too low, the agency is almost certainly cutting corners somewhere. And shortcuts tend to lead to ruin in this capricious and fickle channel. 

If you want lasting organic traffic, if you want to build an SEO brand, if you want to dominate search engines…pony up for the best. 

Conclusion

Investing in SEO can make a significant difference in achieving your business goals. With so many agencies claiming they can get the job done, it is essential to partner with a trustworthy and reliable partner. 

The SEO agencies mentioned above have a proven track record of delivering results, ensuring that they can take your business to new heights. No matter what your business goals are, one of these agencies will undoubtedly serve you well. We hope this blog post has given you valuable insights and helped narrow down your options for finding the best SEO agency in 2024.
