How Much Does SEO Cost? Factors That Shape Pricing

Quality SEO starts at a few thousand dollars monthly because you need to optimize for Google, ChatGPT, AI Overviews, and whatever search platform emerges next.

A successful search campaign demands a rare level of strategic expertise and execution – especially so with the rise of AIOs and LLM-powered platforms. ChatGPT alone now serves hundreds of millions of weekly active users, with younger demographics increasingly treating it as their primary search tool. 

Most of the industry is still catching up to these changes, while a select few – including ourselves at Ellipsis – are already optimizing for AI. We’re currently increasing AI search presence by 20-25% every 30-45 days for our clients.

Realistic cost predictions don’t mean you need to have the highest budget around. We’re seeing results of really quick AIO/LLM performance by targeting the right queries with relevant information. If you have high-quality content, you can still win on important queries. The key is to work with experts who know how to crack this and track your success. And there aren’t many of us around.

This guide will break down the factors that shape SEO agency pricing, budgeting, and why good agencies offer a far greater ROI than freelancers or your in-house team.

Comparing SEO pricing models: Which structure offers the best value

SEO requires sustained effort over several months. One-off projects or hourly work are essentially worthless unless they’re part of a broader, ongoing strategy. 

Even if a single article gets cited in AIOs, any impact won’t be enough to build you a consistent pipeline of conversions. For that, you need to answer more user queries by producing more content. Regularly publishing content boosts your existing pool of knowledge and allows you to compete for multiple queries, widening your conversion potential. 

SEO is an ongoing, never-ending process due to constant changes in search engine algorithms, industry competition, and evolving best practices. The pace has accelerated with AI search platforms growing more intelligent each month. Every change potentially reshapes how your content gets discovered and cited. Continuous adaptation is needed in SEO – even top-ranking sites must frequently review and update content to maintain their presence.

At Ellipsis, we generally work with 3-month minimums because that’s how long it takes to prove our strategy works. While SERP-related results can take up to six months, AI search results can deliver much faster. We’ve even earned an AIO presence within 24 hours of publishing an article! 

The most common pricing structures you’ll encounter:

• Monthly retainers ($1,000 to $5,000+): Predictable costs, consistent work, measurable progress. Given you need a consistent presence across multiple, rapidly evolving search platforms, a monthly retainer is often the best way to achieve long-term, sustainable growth.
• Project-based pricing ($1,000 to $10,000+): Works for specific initiatives like site migrations or technical audits, but won’t drive ongoing growth unless part of a wider strategy.
• Hourly rates ($50 to $200+): Useful for consulting but terrible for execution as a long-term strategy. This model can be good for add-on services to complement a steady SEO campaign.

Performance-based pricing is a further option that sounds appealing but often leads to corner-cutting and black-hat tactics that damage your site in the long run. With pressure to deliver results, an agency might publish keyword-stuffed, low-quality content or secure a bulk of irrelevant links to your site. There may be initial gains, but they’ll be unsustainable for your long-term business goals.

At Ellipsis, we begin all our strategies with a $2,500 AI audit. This provides us and our clients with a detailed overview of current performance, from successes to essential work requirements. We’ll take this data to form the foundation of our Content Growth strategy, starting at $5,000 per month.

After the initial contract term, most agencies shift to rolling monthly contracts. By then, they’ve seen results and understand the value. The relationship becomes about scaling success rather than proving concepts.

If an agency promises quick wins without a long-term commitment, they’re either naive or dishonest. Real SEO takes time, and pricing structures should reflect that reality.

Comparing SEO costs for different business sizes

Here’s how we structure things at Ellipsis – the higher the investment, the quicker the gains. We use our own proprietary software to uncover the most relevant topic opportunities for our clients, enabling our clients to compete in both SERPs and LLM citations.

Alongside creating optimized content, all of our clients are allocated SEO strategic hours, which crucially enable us to be a comprehensive strategic partner to our clients beyond the work with topic research and content production. These are assigned from month to month, wherever needed, to deliver the best possible ROI. 

How to determine your ideal SEO budget

Begin with the question: How quickly do I need results?

The stakes are higher now – businesses ignoring AI search platforms are already missing significant traffic as users increasingly start their research journey with ChatGPT instead of Google. SEO outcomes directly correlate with the volume and quality of work you invest in:

More content > More optimization > = More visibility. 

But not every business needs maximum velocity from day one.

If you’re already generating steady leads through referrals or paid advertising, you can afford to build SEO momentum gradually. Start with a foundational investment and scale up as organic traffic proves its value. Small-to-medium businesses often take this approach – it’s sensible when cash flow matters more than aggressive growth.

However, it’s wise to invest as much as you reasonably can in SEO from the start. The effect of quality content continues to work for years, as more users enter the market with queries that need answering. A single authoritative piece can earn citations across LLMs and Google’s AI Overviews simultaneously, multiplying its reach beyond traditional search results.

At Ellipsis, our Content Growth service starts at four pieces monthly – the absolute minimum for meaningful progress. Larger businesses typically invest in 6-8 pieces monthly, sometimes more. It’s a logical equation – double the content, roughly double the topical opportunities.

“What separates premium packages goes beyond volume. Our higher-tier offerings include Strategic SEO hours – flexible time we allocate based on what will bring the biggest gains for each client. For one month, that might mean technical fixes. Next month, a client case study, industry report, or optimizing product pages when you launch something new. This adaptability matters because SEO is ever-changing.”

– James Baldacchino, Head of Strategy & SEO

Before committing any budget, get an audit. Not just a traditional SEO audit, but an AI SEO Audit that reveals where you appear in ChatGPT responses and Google’s AI Overviews. At Ellipsis, these audits map your entire presence across the new search ecosystem – traditional rankings plus AI citations. Without this visibility, you’re missing a huge market opportunity.

Why an SEO agency is always the best investment

You’ve got three options for SEO:

1. Hire an agency.
2. Find a freelancer.
3. Build an in-house team. 

Save yourself months of deliberation, because the agency wins every time. Freelancers may cost less. In-house teams may give you more control. But experienced agencies have done this before, seen your specific problems, and understand how to solve them. Good SEO agencies are keeping up with the times and constantly looking to evolve.

An experienced agency has all the tools it needs to operate. Few freelancers can afford these tools to the same degree, and in-house teams rarely have the resources to identify, purchase, and sufficiently set up everything that’s needed. 

With the right agency, it’s all present and ready to go – Ellipsis built our tech to fill software gaps in the market and deliver better results for our clients. This includes our own FALCON AI tool for predictive topic research, RORY for understanding content gaps, and tracking tools for monitoring performance across AI platforms. 

Here’s an example of our proprietary AIO/LLM tracking dashboards monitoring Share of Voice (SoV) data for a client – i.e., the percentage of recommendations that go to them. In just under one month, our client has seen a 35% rise in SoV, and this is pretty typical across all of our accounts:

Here’s an example below of how we track a specific query in our dashboard. We can see the sources of citations, in relation to the topic: 

The topic also generates natural language queries around the intent, giving us a data-led foundation for planning a content strategy: 

You literally can’t get these anywhere else because our tech is so far ahead of the market.

“Our software can show clients exactly where they’re cited across every AI platform, for every query that matters. We’re the difference between guessing what content might work and knowing what will perform before you publish it.”

– James Baldacchino, Head of Strategy & SEO

And let’s talk about resources. When you hire Ellipsis, you’re getting a Content Manager, Strategy Lead, and dedicated writers, all supported by specialists who jump in whenever needed. We’ve the resources to handle technical audits, AI strategies, and whatever else brings results. Try getting the same range of expertise from a single freelancer or affording it with an in-house team.

Another major gain agencies bring is agility. SEO changes fast. In March ’25, close to 18% of all Google searches showed an AIO directly on the results page, and that number is growing. 

A few months ago, nobody was optimizing for ChatGPT search, but today it’s driving real traffic for our clients. AIOs now dominate results for high-intent searches, showing up at the top for 74% of problem-solving and 69% of question-based queries. 

The companies still chasing traditional rankings – focusing on position one in Google – are losing out.

You want the people who are working on your SEO to deliver high-quality work, but more importantly, you want strategic partners who can stay on the pulse of how SEO is changing and adapt to this with lightning speed. 

We spot shifts before they become trends. We test strategies across multiple clients, learning what works without risking your entire budget on experiments. 

SEO has become too complex, too technical, and too fast-moving for anything but dedicated agencies to handle effectively. It’s the cost of actually competing in modern search.
