SEO services have evolved significantly in recent years, driven by changes in search behavior, AI-powered results, and rising competition across industries.
To give you the most accurate picture of the industry today, we’ve combined data from multiple sources, including our survey of 1,200 business owners.
In this report, you’ll learn:
How much businesses spend on SEO services today
Where companies actually find and hire SEO providers
What factors influence the decision to choose one agency over another
Why clients leave (or stay with) their SEO provider
Key trends shaping the future of SEO services
Let’s dive into the data.
Highlights and Key Statistics:
1. Companies spend $119.4 billion on SEO and digital marketing consulting each year in the US.
2. We found a strong correlation between higher spending and higher client satisfaction in small business SEO. In fact, clients who spent over $500/month were 53.3% more likely to be “extremely satisfied” compared to those who spent less than $500/month.
3. Most small business owners find SEO providers through referrals, Google searches, and online reviews. A small fraction of SEO clients (8%) found their current provider from online advertising.
4. When it comes to choosing a provider, 74% of business owners consider an SEO provider’s reputation “very” or “extremely” important. Monthly cost and the provider’s own Google rankings were also noted as important factors.
5. Overall, SEO client satisfaction is decidedly low. Only 30% would recommend their current SEO provider to a friend or colleague. However, we found that client satisfaction among marketing agencies was higher than that of freelancers.
6. SEO provider turnover is high. 65% of our panel stated that they’ve worked with several different SEO providers. 25% have worked with 3 or more providers.
We have more detailed and expanded findings below.
Average Monthly SEO Spend
In 2025, US organizations spent $119.4 billion on SEO and digital marketing consulting.
Our 2019 research found that small businesses spend $497.16 per month on SEO services.
However, we did discover a large range in SEO spending. Half of our respondents reported spending less than $1,000 per year on SEO. 14% spend $5k+ per year. Only 2% spend over $25k/year.
We also found that agencies tend to get paid significantly more than freelance SEO providers.
Specifically, agencies were 2x more likely to get paid $1k-$2k/month than freelancers, who mostly get paid in the $500-$1k per month range.
Agencies also tend to dominate the high-end pricing range (clients that spend $10k-$25k/year on SEO).
As you can see, 24% of small businesses that work with agencies spend between $10k-$25k/year, compared with 2% that work with a freelance SEO.
Monthly Spend Is Tied To Client Satisfaction
When it comes to SEO, do you “get what you pay for”?
According to our data, yes.
Specifically, we discovered that clients spending over $500/month were 53.3% more likely to consider themselves “extremely satisfied” compared to people who spend less than $500/month.
We also found a clear relationship between dissatisfaction levels and cost.
Specifically, business owners who spent less than $500/month were 75% more likely to be dissatisfied than those who invested at least $500/month in SEO.
This relationship played out whether a client worked with a freelancer, agency, or a mix of both.

Referrals and Google Searches Are the Top Ways Businesses Are Finding SEOs
When someone wants to hire an SEO agency, where do they look?
According to our panel, most people find potential SEO service providers through word of mouth, Google searches, and online review platforms (like Yelp).
On the other hand, relatively few find SEO providers through online or offline advertising, or referrals from other vendors (like web designers or writers).
If you’re an agency owner or a freelancer, this is a key finding. If you know where small business owners look to find SEO service providers, you can invest resources to make sure your business has a presence in those places.

Reputation and Cost are Key Factors Involved In Choosing a Provider
Demand for SEO services continues to grow as search becomes more complex and harder to manage in-house.
In fact, recent data shows that 61% of companies hire SEO agencies due to a lack of internal expertise, while others turn to external providers when they don’t have the time, resources, or results needed to scale.
Most common reasons for using SEO services:
Lack expertise – 26.87%
Lack resources – 22.70%
More cost-effective – 21.48%
Poor in-house SEO results – 15.48%
Lack sufficient time – 10.70%
But hiring an agency isn’t just about capability. Once someone finds a list of potential providers, how do they decide which one to go with?
We discovered that reputation, cost, and a provider’s own Google rankings influenced their decision the most.
Small business owners cited client case studies and the provider’s social media presence as significantly less important.
However, even these relatively minor factors played a role in whether or not someone decided to work with a particular SEO provider. For example, 55% of our panel cited “referrals” as an important consideration.
Although the importance of referrals pales in comparison to a provider’s reputation (55% vs. 74%), it’s still something that influenced more than half of the people we spoke to.
Interestingly, we found that a provider’s location mattered quite a bit.
Only 51% knew exactly where their SEO provider was located.
However, 78% of US-based small businesses stated that knowing their provider’s location was “extremely” or “very” important (with 46% stating that a known location was “extremely important”).
If you provide SEO services, making your location clear and obvious may help you land more SEO clients.

The Vast Majority of Business Owners Expect SEO Services To Increase Customers and Traffic
A recent 2025 survey found that 91% of people who used SEO services reported a positive impact on website performance and marketing goals.
As such, it’s no surprise that expectations are high when working with an SEO provider.
According to our survey, the most important expectations are “accessing new customers”, “increasing traffic”, “increasing brand awareness”, and “building trust” as most important.
“Gaining social media followers”, “increasing number of email subscribers”, and “helping to attract new talent” were cited as relatively unimportant.
In fact, even though this is a common goal set by marketing agencies, only 26% of respondents cited “getting followers on social media sites” as extremely important.
This finding is especially key for SEO providers that are taking on new clients.
For example, a newly-hired SEO provider that says, “Our first step is going to be to get more likes on your Facebook page” isn’t speaking their client’s language.
On the other hand, kicking off the client-provider relationship with: “I look forward to helping you get more targeted traffic and customers” will likely result in a more satisfied client.
Needless to say, for the relationship to last, you need to deliver on those promises (more on that later). But it does help to understand what clients hope to get out of SEO so you can mold your services and reports based on that.
SEO ROI: What Businesses Can Expect
SEO is widely regarded as one of the highest-return marketing channels, with some estimates placing the average ROI at around 22:1, meaning businesses earn roughly $22 for every $1 invested.
And around 1 in 3 qualified leads (34%) come directly from SEO efforts.
However, ROI varies significantly across industries:
Medical Device – 1,183% ROI, 13 months breakeven
Higher Education & College – 994% ROI, 13 months breakeven
Oil & Gas – 906% ROI, 10 months breakeven
Industrial IoT – 866% ROI, 7 months breakeven
Pharmaceutical – 826% ROI, 9 months breakeven
Manufacturing – 813% ROI, 9 months breakeven
Biotech – 788% ROI, 8 months breakeven
Solar Energy – 770% ROI, 9 months breakeven
Commercial Insurance – 758% ROI, 9 months breakeven
B2B SaaS – 702% ROI, 7 months breakeven
Construction – 681% ROI, 5 months breakeven
HVAC Services – 678% ROI, 6 months breakeven
IT Staffing – 612% ROI, 10 months breakeven
Legal Services – 526% ROI, 14 months breakeven
Healthcare – 532% ROI, 11 months breakeven
Financial Services – 447% ROI, 9 months breakeven
E-commerce – 317% ROI, 9 months breakeven
The rapid emergence of AI also has a bearing on SEO ROI, with 39% reporting a “moderate increase” and 29% claiming a “significant ROI increase”. Only 1% claim that AI reduces their SEO ROI.

Overall Satisfaction With SEO Services Is Low
SEO is a long-term investment, and results often take time to materialize; many campaigns require 6–12 months just to break even.
That slower payoff, combined with unclear reporting or misaligned expectations, can leave many businesses frustrated with the SEO services they receive.
In our study, we asked our panelists to rate their current SEO provider (or the last SEO provider they worked with) using the Net Promoter Score.
The results were markedly low.
First off, we found that only 30% of small business owners would recommend their current SEO provider.
Importantly, 30% of our respondents considered themselves “detractors”. Which means they would leave a negative review for their last or current SEO provider.
In fact, the SEO services industry as a whole has an NPS score of 0, which is considered “not likely to recommend”.
When we broke down the NPS scores among agencies, freelancers, and a combination of freelancer and agency, we discovered that agencies had a higher average NPS score than freelancers.
However, all three types of services had fairly low NPS scores.
Clients Cite Lack of Education and Resources as Top Reasons for Low Satisfaction Levels
Delivering effective SEO requires significant investment in talent, tools, and ongoing strategy, something many businesses underestimate when hiring a provider.
Building comparable in-house capabilities can cost $150K–$250K+ for senior talent plus thousands per month in tools, which helps explain why expectations often exceed what lower-cost or under-resourced SEO services can realistically deliver.
NPS is a helpful benchmark. However, NPS can only tell you so much. In other words, it’s difficult to understand why SEO services have such low levels of satisfaction.
That’s why we decided to dig deeper into this finding.
And when we dug a bit deeper to understand more about what’s happening, we uncovered a few surprising insights.
First, many unhappy SEO clients fully or partially blamed themselves.
Specifically, 50% stated that “I feel like I need more training to fully benefit from what SEO offers”, and 28% told us that they “do not have the staff resources to properly benefit from SEO”.
This means that low satisfaction levels aren’t solely due to poor quality work. In fact, many clients are simply not in a position to benefit from SEO due to a lack of resources.
Plus, even clients with resources may not make SEO a priority because they don’t have the training to fully understand how SEO benefits them.
For example, let’s say an SEO provider wants to change a title tag on a client’s site. But it doesn’t happen because their developer is swamped with a website redesign. Also, this client may not understand that this simple change can increase their Google traffic due to a lack of training. So they don’t make that change a priority. And progress stalls.
Which leads us to our second interesting finding, the importance of reporting and transparency.
27% of the clients we spoke with agreed with the statement: “I find SEO to be confusing and unclear about what services they offer.” 25% said that “I am not sure what I am really paying for with SEO.”
In other words, many clients are confused about what their provider is doing for them or what they’re getting out of the arrangement.
These are two points that could be remedied with better reporting and increased transparency.
I should point out that a fair number of clients stated that “I feel like SEO companies are very unreliable” and “I don’t think SEO is worth the money for my business.”
Which means that a simple lack of results and ROI is often the culprit behind low client satisfaction levels.
However, as you just saw, there are usually non-performance-based factors at play as well.

Turnover In the SEO Services Industry Is Extremely High
Likely due to low global satisfaction levels, we found high levels of turnover in the SEO services industry.
Specifically, we found that 65% of small business owners have worked with at least one SEO provider before:
We also found that 1/4th of our panel have worked with 3 or more providers:
However, our data suggests that most clients don’t switch between SEO providers without careful consideration.
In fact, the clients in our panel have been working with their current SEO service for an average of 3 years. And lapsed clients give their service provider an average of 2 years to deliver before moving on.
That said, we did discover a small subset of clients that do rapidly switch between different providers.
These “rapid switchers” tend to hire and fire SEO companies at a fever pitch.
For example, we classified 10% of our panelists as “rapid switchers” (worked with 3 or more SEO providers over the last year).

Most SEO Clients Leave Due to Lack of Results and Cost
We wanted to know why people decide to leave their current SEO provider or switch to another company.
We referred to people who worked with multiple SEO providers as “lapsed clients”. And we asked this subset of lapsed users what went into their decision.
Here were the results:
Not surprisingly, 82% of our respondents cited “Dissatisfaction with business results” as a factor in their decision. 81% reported that cost played a large role as well.
This suggests that clients don’t look at results in a vacuum. They also pay attention to the ROI that they’re getting from SEO. In other words, delivering results for clients is one thing. But it’s also important to demonstrate the ROI that SEO has on their business. Otherwise, they may leave.
Although lack of results and cost were the two largest factors, they weren’t the only reasons that clients decided to stop working with an SEO provider.
In fact, 80% of lapsed clients stated that they found a better option on their own, which suggests that clients are happy to shop around for an alternative to their current SEO provider.
And 34% cited poor “customer service/ responsiveness” as a factor in their decision.
However, relatively few clients cited “pitched by a competitor” as a reason for leaving. In other words, as long as you can keep your clients happy, they’re not likely to leave. This remains true even if a competitor attempts to poach your client with a better offer.
We also asked our “lapsed clients” panelists to describe to us why they decided to stop using an SEO service. Here’s a sample of those responses:
We also asked a group of users who were happy with their SEO service (“existing clients”) what they liked about it. Here’s what they told us:

Existing Clients are 2x More Likely to Be Web Savvy Than Lapsed Clients
We asked our panel to self-report their level of “web savviness”.
Here were the results:
As you can see, 37% of SEO clients consider their web savviness as “somewhat” or “not very”.
The upshot here is that many clients simply don’t have the web savviness to understand key digital marketing terms, like “title tags”, “CSS”, and “backlinks”. This suggests that SEO companies should largely avoid this sort of jargon in favor of terms like “leads”, “sales”, and “first page Google rankings”.
In fact, this is backed up by another finding from our panel: that lapsed clients are significantly more likely to consider themselves not web savvy.
Specifically, we found that existing clients were 2x more likely to consider themselves “extremely web savvy” than lapsed clients.
This suggests that web-savvy users are in a better position to understand how their SEO service is helping them. So they decide to stay. On the other hand, clients who aren’t web savvy may not fully understand what they’re getting from their SEO provider. So they decide to leave.
