Inhouse SEO or Agency? Both! Here’s Why

A lot of people treat this like an either-or decision.

Either you build an in house SEO team or hire a SEO agency to handle everything for you. But honestly, the best SEO strategy is usually somewhere in the middle.

Some parts of SEO make perfect sense to manage in house. Others are way more efficient to outsource to an agency with the right expertise, systems, and people already in place.

What works best really depends on your business, your resources, and how competitive your space is.

In this article, I’ll break down where inhouse SEO works better, where agency SEO has the advantage, and why a hybrid approach is usually the smartest option.

Key Takeaways:

• Inhouse SEO can be more cost-effective for certain businesses, especially if your SEO efforts are focused on local SEO, content updates, or maintaining an existing digital marketing presence.
• A SEO agency gives you immediate expertise without needing to hire, train, or manage a large internal team for every SEO task.
• Technical SEO, link building, and large-scale outreach are usually much harder to manage in house because they require specialized expertise, systems, and consistent execution.
• The strongest SEO strategy is usually hybrid: manage content and on-page SEO in house, outsource technical SEO fixes when needed, and use an agency for link building and AI visibility.
• Outsourcing SEO to a pay-per-result agency gives you flexibility, especially when you need to rank a specific page or improve search engine visibility without committing to a massive long-term SEO project.

Inhouse SEO Benefits

POTENTIALLY More Cost-Effective

But not necessarily.

There are a lot of moving parts in SEO, and what works for one company does not automatically make sense for another.

Whether inhouse SEO is actually cheaper depends entirely on your business model, competition level, and overall marketing strategy.

For example, if you are a small business with a brick-and-mortar location downtown and tons of foot traffic, you might not need massive SEO efforts to stay profitable.

In that case, having a small in house setup with a SEO specialist handling local SEO, social media, and basic search engine visibility can work perfectly fine.

You are not trying to dominate a competitive national keyword. You just need people nearby to find your business when they search.

The same applies to larger companies that already get business consistently but are lacking in the SEO department.

Hiring a few people internally to improve the site structure, clean up technical issues, and manage ongoing SEO work can make more sense than bringing in a full SEO agency.

But things change fast in competitive industries.

If you are a tiny SaaS startup in spaces like SEO tools, sales software, or digital marketing, building visibility is much harder.

Showing up in search engine results and AI search takes a serious amount of work.

Take link building, for example.

You usually need multiple people handling outreach consistently over a long period of time to stand out in crowded search results.

Those people also need the right SEO tools, proper processes, and someone managing quality control to make sure the links are actually helping your SEO strategy instead of hurting it.

And then there is technical SEO on top of that, content marketing, tracking performance, managing campaigns, and adapting to changing SEO trends.

At that point, your small in house SEO team can turn into a pretty large investment very quickly.

In this scenario, it’s much easier and more cost-effective to hire an agency.

Flexibility

One advantage of managing SEO in house is flexibility, especially if you are working with a smaller internal team.

You can end up with a one-man-army type setup where the same person handles multiple SEO tasks across the business.

One day they are writing content, the next they are building links, updating pages, or even helping with outreach and sales activity.

That kind of flexibility is hard to get with a traditional agency structure.

And if your company is financially stable enough, you can also invest in SEO training and gradually expand your team’s expertise over time.

So, for example, you can take on a junior SEO specialist for as little as 3-5K monthly and help them develop new skills over time.

Someone handling content today can eventually learn parts of technical SEO, outreach, analytics, or even broader strategy work with the right systems and support.

So the company wins because you are building stronger internal capabilities, and employees win because they develop more valuable skills beyond a single role.

This setup also makes it easier to adapt your SEO strategy quickly.

Instead of waiting for approvals or going through layers of communication, your in house team can react immediately to SEO trends, new search engine updates, or shifts in your marketing strategy.

Of course, this only works if the workload is manageable.

Agency SEO Benefits

Expertise Without Having to Learn

This is probably the biggest advantage a SEO agency has over handling everything in house.

With a good agency, you do not need to become an SEO expert yourself in order to get results.

You are essentially plugging directly into existing expertise, systems, workflows, and people who already do this every single day.

That matters because modern SEO is not just one skill anymore.

You have technical SEO, content marketing, link building, analytics, AI visibility, on-page optimization, outreach, reporting, and strategy all happening at the same time.

Keeping up with search engine updates and changing SEO trends is practically a full-time job on its own.

One look at Search Engine Journal’s upload schedule says a lot. Three articles per day is simply too much to keep up with:

A strong agency SEO setup already has specialists for these areas, whether that is an SEO strategist, SEO consultant, outreach team, or technical SEO expert handling audits and implementation recommendations.

The catch is that you still need to know how to choose the right agency, because there are plenty that will waste your time and money.

The easiest way to avoid that is to be extremely clear about your SEO goals from the start.

Do you want:

• More organic traffic?
• Better AI visibility?
• Higher rankings for a specific landing page?
• More qualified leads from search engines?

The more specific you are, the easier it becomes to evaluate whether the agency actually has a real SEO strategy behind what they are offering.

You should also ask detailed questions.

Things like:

• How exactly will you help achieve this goal?
• What does the day-to-day SEO work look like?
• Which strategies are you using?
• How do you approach link building and technical SEO?
• What does a typical SEO campaign include?

A good SEO company should be able to answer these clearly without hiding behind vague language.

No Wind Up Period

This is another huge advantage of outsourcing SEO to an agency.

Once you sign the contract or place an order, the work usually starts immediately. ‘

The strategy is already there, the systems are already built, and the people handling the SEO activity already know what they are doing.

Building that internally takes time.

For example, it took Visme around a year to grow to 500K traffic from ~100K using a mix of internal specialists and even a custom-built internal toolset.

And that’s already a huge amount for a “starting” point.

Now imagine how long it takes to get up from 0.

Even if you hire great people for an in house SEO team, there is still a long ramp-up period. You need to recruit, onboard, train, assign responsibilities, build processes, and make sure everyone is aligned on the overall SEO strategy.

And if you are hiring for multiple roles like technical SEO, content, outreach, and analytics, that process can easily take months before the team is fully operational.

Hybrid is the Best of Both Worlds

Honestly, this is the setup that makes the most sense for most companies.

The reality is that some parts of SEO are just better suited for an internal house setup, while others are much more efficient to outsource to a SEO agency with specialized expertise.

Trying to force everything in house usually creates unnecessary overhead.

But outsourcing absolutely everything is not ideal either because nobody understands your product, audience, and positioning better than your own team.

The best approach is usually splitting responsibilities based on what actually makes sense operationally.

For example:

• Manage content and on-page SEO in house
• Use a freelance developer for technical SEO fixes
• Outsource link building to an agency

Content and on-page work tend to benefit the most from an internal team because they require product knowledge, understanding customer pain points, and aligning with your broader digital marketing and content marketing strategy.

Technical SEO is different.

A lot of technical issues are one-time fixes or occasional maintenance tasks. You usually do not need a full-time technical SEO specialist sitting in house unless your site is extremely large or complex. In most cases, having a developer freelance for specific technical SEO tasks is way more efficient.

Link building is where outsourcing usually makes the biggest difference.

Doing link building properly requires prospecting, outreach systems, relationship building, quality control, and consistency over a long period of time.

It is difficult to build all of that internally unless SEO is already a massive part of your business.

That is why working with an SEO agency on a pay-per-result basis makes so much sense.

You are not locked into huge retainers or forced into a long-term commitment.

At Respona, the process is designed to be as flexible as possible depending on what your SEO goals actually are.

You start by placing an order with your own custom guidelines.

That can include target pages, preferred anchor text, target search queries, niche requirements, DR ranges, or the type of placements you are looking for as part of your overall SEO strategy.

From there, the team handles the hard part for you.

That includes prospecting, outreach, relationship building, negotiations, follow-ups, and securing placements using fully white-hat link building methods.

So instead of building a full outreach system in house, your internal team can stay focused on content, product positioning, and broader digital marketing priorities.

And because it is pay-per-result, it works at basically any scale.

Whether you need one high-quality placement for a specific landing page or thousands of links across a larger SEO campaign, you can scale up or down depending on your current needs without committing to a massive long-term contract.

You can also use the campaigns feature to make the process much more targeted.

The tool takes your target search queries and identifies articles that are already being cited by AI answer engines and already performing well in search engine results.

Instead of building random backlinks, you can focus specifically on placements that already have visibility for the exact topics relevant to your business.

Those placements help in three ways at once:

• They strengthen organic ranking signals through link building
• They drive targeted traffic from articles already getting visibility
• They improve AI visibility by increasing your chances of being cited in AI search experiences

Before anything goes live, you can review placements and approve orders directly inside the platform.

And after placements are secured, campaigns continue tracking your visibility across AI answer engines and search engine results over time, so you can actually measure whether your SEO efforts are improving visibility for your target queries.

Now Over to You

At the end of the day, this is not really an inhouse SEO vs agency debate.

The best setup for most companies is usually a mix of both.

Keep content and positioning in house where your internal team understands the product best. Outsource specialized SEO work like link building and technical SEO to people who already have the systems and expertise built out.

That way, you get the flexibility of an internal house setup without wasting resources trying to manage every part of SEO yourself.

And if link building is the part slowing you down, you can simply place an order and let Respona handle the outreach, placements, and AI visibility side for you.
