What Does a Technical SEO Agency Do?

A technical SEO agency is responsible for  auditing a website’s infrastructure (URL structure, loading speed, site navigation, etc.) to find and fix any performance issues so that Google and other search engines can easily index the site.

Technical SEO covers a vast and often misunderstood area separate from the traditional SEO work of on-site optimization and link building, which includes tasks like:

  • Using XML sitemaps, tags and robots.txt files to ensure proper crawlability (the capacity of Google’s bots to crawl a website) and indexability (the capacity that said bots have to index a page and include it in Google’s SERPs) 
  • Analyzing the site structure to improve its crawlability, internal linking, and usability
  • Optimizing the URL structure for a keyword
  • Fixing any involuntary error (404) pages and redirects
  • Using the canonical tag to avoid duplicate content
  • Improving page loading speed
  • Creating structured data
  • Maximizing the value of internal links for building an optimal link profile

Benefits of Hiring a Technical SEO Agency 🤔

Now that you have a clear idea about what technical SEO entails, here are a few reason for hiring an agency.

Get the Foundation Right

Optimizing your tags and building links are great, but if Google can’t find and index your pages, your effort to rank will be for nothing. Your website must be properly structured so that Google can understand its content and rank it in its index. This is why we say technical SEO is the “foundation” of SEO.

Ideally, you want to think of the bullet points mentioned in the previous section before you build or revamp your website so that your web development team creates it with SEO in mind right from the start. However, if redesigning your website is out of the picture, you should at least fix the most glaring issues that cause the underwhelming results you’re getting from your site.

If this all sounds stressful and complex, don’t worry, because a technical SEO agency can take care of all this for you.

Balance SEO with UX

In the last few years, Google has added new user interaction signals to its ranking algorithm, such as time on site and bounce rate. Google has even received a patent for a “site quality score” that uses time on site (or “click length”).

Although Google has never publicly acknowledged this fact, they likely use user signals to some extent, which is why you should design a user-friendly site. A website with a strong UX not only will improve your SEO strategy, but has several other benefits, such as:

  • Higher customer satisfaction and loyalty
  • Increased conversions
  • Higher revenue and profits

A technical SEO agency can assist your business with improving your web design so that your design team (or agency) can revamp your site taking both Google and humans in mind.

Boost Your Marketing Performance

Another benefit of having a well-designed, fast-loading website is that it can increase your performance across the board. According to a survey by Unbounce: 

Nearly 70% of consumers say that page speed affects their desire to buy from an online retailer.

As per Portent’s analysis: “When pages load in 1 second, the average conversion rate is almost 40%. At a 2-second load time, the conversion rate already drops to 34%. At 3 seconds, the conversion rate begins to level off at 29% and reaches its lowest at a 6-second load time.”

Ideal page load speed graph

Any change in your website that makes your visitors’ experience more pleasurable and seamless will make it easier for your marketing messaging to work. Once again, this fact works like the basis of everything else that comes afterward (your marketing strategy, that is).

What to Look for in a Technical SEO Agency 👀

Technical Skills

First and foremost, you want to work with an agency that has technical people on its payroll. Although not everything within technical SEO requires coding skills, implementing the suggested changes from a technical SEO audit usually does. 

One such case is creating a new robots.txt that excludes some pages from being crawled or indexed, a task that requires an understanding of HTTP and regular expressions.

If the agency says that it takes care of the execution of technical SEO, make sure they have web developers on staff. Remember that SEO specialists aren’t always technically gifted. 

Proven Expertise

You don’t want to leave your website in the hands of an agency that hasn’t worked on similar projects. Years in business doesn’t matter as much as the breadth, relevance, and quality of the case studies they provide.

When evaluating a technical SEO firm, make sure they talk about past customers they’ve worked with, the tasks they were responsible for, and their results. If they don’t offer any case studies on their website, ask for them.

Holistic Approach to SEO and Digital Marketing

An agency specializing in technical SEO while disregarding the rest of your SEO strategy isn’t the right fit for your business. The same applies if the agency doesn’t take your overall digital marketing strategy into consideration.

Technical SEO has its time and place. It’s the foundation, as we saw previously, not the entire house. Once your technical SEO issues are fixed, make sure the agency helps you with the other parts of your plan, whether that’s your on-site optimization, link building or content creation.

How Much Do Technical SEO Agencies Charge?

Technical SEO agencies price their services depending on several factors:

  • Complexity: This is the crux of the matter, as technical SEO can affect your development, design and marketing teams. Communication, coordination and execution are paramount, but they are also resource-intensive.
  • Deliverables: The issues that the technical audit the agency performs will show you what needs to be done. Each task will become its own deliverable. The more deliverables there are, the costlier the services will be.

In the next section, you will see that the top five technical SEO agencies charge anywhere from $1,000 to $5,000 (or even more) per project, depending on the factors mentioned above.

The way these agencies charge may be based on any of the following pricing mechanisms:

  • Flat fee: If the project is small and highly targeted to fulfill one objective (say, fix your slow page performance), they may charge you a specific amount (say, $2,000). The benefit of this method is that there won’t be any surprises once it’s time to foot the bill.
  • Hourly based fees: Once a project becomes more complex and time-consuming, an agency may charge you a fixed hourly fee that expands according to the work done. The benefit of this method is that it guarantees the fulfillment of your project’s goals. However, the final price is likely higher than in a flat-fee project and harder to estimate.

Ready to Hire the Right Technical SEO Agency for Your Business?

If your business has followed every Google guideline and your website is still not performing as well as it should be, you may need to contact a technical SEO agency like the ones mentioned in this article.
