What Is an SEO Agency?

Once upon a time, Search Engine Optimization was all about choosing the right keywords and placing them appropriately and effectively throughout your website.

While keyword research and placement still have their part to play, these days successful SEO is a multi-faceted operation that includes everything, like:

Let’s face it: That’s a lot. Even if you’ve got your content down to an art form, there’s so much to think about, plan for, and put into place that it’s usually too much for a business to manage successfully.

That’s to say nothing of the fact that Google’s algorithms are always changing, meaning that SEO best practices are changing, too. As such, if you DIY your SEO, there’s always a chance that you’re missing the mark when it comes to implementing the best strategies and the latest SEO techniques.

An SEO firm solves all of these problems for its clients.

An SEO agency is a marketing company that has in-house experts for each aspect of search engine optimization, such as website audits, link building, content marketing and creating an overall SEO strategy, in order to improve a your visibility in the search engines.

With a team of certified experts in all aspects of SEO, these agencies easily stay on top of current developments and algorithm changes within the major search engines. They put this expertise to work by fine-tuning an approach that helps clients improve their search visibility, increase click-through rates and, ultimately, boost conversion rates.

The Benefits of Hiring an SEO Firm

Hiring a reputable SEO agency may cost money in the short-term, but the long-term results from an effective strategy can pay dividends in terms of organic growth and increased conversions.

Here are several key benefits of outsourcing your Search Engine Optimization.

Keep on Top of Changing Algorithms

Google likes to change its algorithms a lot, and that can make it difficult for many businesses to maintain consistent ranking in the search engines. What once worked for you in terms of driving organic traffic to your site may no longer be producing the results you need. And without a good deal of SEO expertise, it can be difficult to figure out what you need to do to start improve your ranking and conversions.

This is where the best SEO companies are worth their weight in gold.

They constantly keep abreast of the latest developments in the world of search and adapt what they do to help their clients with individual needs maintain an effective online presence.

Implement SEO Best Practices

It can’t have escaped your attention that there are thousands of articles, tutorials and videos out there that offer to share with you the most effective SEO tactics.

The problem is that wading through that wealth of information to find those diamonds among the coal can be an enormous undertaking, particularly when many articles you read are a few years old or they seem to contradict one another.

With outsourced SEO, this isn’t something you need to worry about.

Your chosen agency’s experts combine their experience with tried-and-tested techniques that have proven to work to create and implement the most effective SEO strategy for your brand.

Take Advantage of Better Backlink Building

Read anything about SEO and it won’t be long before you hear about the importance of generating quality backlinks from reputable, authoritative sites.

This is a big task for any business owner to take on by themselves. This is especially true if you’re new to the very concept of link-building and don’t know which sites are worth getting a link from, let alone how to go about getting it.

An SEO firm can prove their value in this regard. They know how to identify the best websites to reach out to for link-building purposes and how to approach them.

Save Time and Money

Perhaps the most significant benefit of hiring a digital SEO company is that they can be significantly more cost-effective than either doing the work yourself or hiring your own in-house SEO team.

SEO is not a one-and-done job. Instead, it’s an ongoing process that can take up a lot of time. If you’re a small business owner, those are precious hours in which you’re not providing value for your customers and generating revenue.

If you’re a medium or large business, the cost of hiring in-house staff (think salaries, overheads, benefits, etc.) can work out to be much more expensive than the cost of outsourcing.

How to Choose the Best SEO Agency

So, you’ve made up your mind that hiring an SEO firm is the best move for your business, but with so many options to choose from, there’s still the not-so-small matter of picking the right one.

Below, we’ve highlighted some of the common traits that set the top SEO companies apart from the rest, as well as those all-important red flags that tell you a particular agency should be avoided.

They Communicate Clearly and in Concrete Terms

For some business owners, the world of SEO can be very confusing, which is why they decided to hire an agency in the first place. The problem is that some less-than-reputable agencies will take advantage of that.

Like a magician trying to keep his tricks a closely guarded secret, they shroud their consultation in mystery, throwing out industry jargon with aplomb and promising big results without ever explaining exactly how they’re going to produce them. Avoid these agencies.

🚩  Not only does non-transparency make things more baffling for you, but it’s also a big red flag that they’re either deliberately making SEO sound mysterious to charge you for more than you need or using black hat SEO tactics that are only going to do your site more harm than good (like getting penalized by Google).

✅  Instead, look for an agency that speaks your language to clearly explain what they’re going to do, how they’re going to do it, and how much it will cost you. That way, you not only get the peace of mind that you’re working with a reputable, legitimate agency but, more importantly, you also know exactly what you’re paying for.

They Use Legitimate SEO Strategies and Techniques

We mentioned the term “black hat SEO” a moment ago, so let’s expand on that. The term refers to the use of various tactics such as keyword stuffing, domain masking and buying links which are essentially an attempt to “cheat” a website’s way to the top of search results.

🚩  Unsurprisingly, cheating never works. Search engines like Google are smarter than even the smartest black hat SEOs. They can identify when these underhanded tactics are being used and penalize your website, basically achieving the very opposite of what you paid your agency to do.

✅  So the best approach is to work with an agency that uses legitimate, Google-friendly tools and strategies, which are referred to as “white hat SEO.” White hat SEO includes:

  • Keyword research
  • Indexing and Site Architecture
  • On-Page SEO (like URL structure, H1 headlines, meta description, image SEO)
  • Link building

They Offer Measurable, Realistic Results

Watch out for any SEO company who make vague promises about “boosting organic traffic,” as well as those who may be promising more than they can guarantee to deliver.

SEO is a long-game. Work that’s done today may not begin to bear fruit until six months down the line and, at that point, a whole multitude of factors may influence the exact results gained.

🚩  So it’s wise to stay away from anyone who says they can guarantee to have you on the first page of Google for targeted keywords within a few weeks.

✅  Instead, look for an SEO company that promise realistic, measurable results within a reasonable timeframe.

They Have an Excellent Reputation

Signing up with an SEO firm can be a big step for many businesses, so it’s important not to solely base any decisions on their sales pitch.

🚩   If a company doesn’t have any reviews online anywhere, feel free to ask them for details about their past clients. If they can’t provide that either, that may signify that they’ve got something to hide.

✅  Instead, look at their testimonials, reviews and case studies and ask yourself:

  • Are these from legitimate businesses?
  • Do they speak highly of the agency itself?
  • Do those case studies show the kind of results that I’m after?

What Is the Best SEO Agency to Work with in 2023?
