SEO tools were the most replaced martech application in 2025 — but not for the reason you might expect.

According to the 2025 MarTech Replacement Survey, SEO platforms topped the list of replaced tools for the first time, overtaking categories like marketing automation platforms (MAPs), which had led for the past five years.

At first glance, that might suggest instability in SEO. After all, the discipline is being reshaped by LLMs, AI-generated answers, and the rise of zero-click search experiences — all of which challenge traditional keyword tracking and ranking-based workflows.

But the data tells a more nuanced story.

SEO tools: most replaced, but stabilizing

Even though SEO tools were the most replaced category in 2025, they were replaced at a slower rate than in prior years.

In other words, they’re now the most commonly replaced — but also more stable than before.

That shift suggests a maturing category. Rather than widespread churn, you appear to be consolidating, upgrading, or refining your SEO stack as search evolves.

Meanwhile, several other major martech categories saw sharper year-over-year declines in replacements:

• CRM replacements fell more than 12% from 2024 to 2025, reaching their lowest level in the survey’s history.
• MAPs, email platforms, and CMS tools also declined compared to 2024.

Why SEO tools are being replaced

So if SEO tools aren’t being swapped out due to instability, what’s driving the changes?

The survey points to three primary factors:

1. AI capabilities

For the first time, the survey asked about AI’s role in replacement decisions — and the impact was significant.

• 37.1% cited AI capabilities as an important factor.
• 33.9% said they wanted AI capabilities when replacing a tool.

This reflects a broader shift in SEO tooling, with platforms rapidly integrating AI for:

• Content generation and optimization.
• SERP analysis and intent modeling.
• Workflow automation.

In many cases, replacing your SEO tool isn’t about abandoning SEO — it’s about upgrading to AI-native capabilities.

2. Cost pressures

Cost has become a major driver of martech replacement decisions, including SEO tools:

• 43.8% of marketers cited cost reduction as a reason for replacing an application in 2025.
• That’s up sharply from 23% in 2024 and 22% in 2023.

This suggests growing pressure to optimize and rationalize your SEO tech stack, especially as you evaluate overlapping functionality across tools.

3. Changing needs in a shifting search landscape

As search behavior changes, so do expectations for SEO platforms.

Traditional rank tracking and keyword monitoring are no longer sufficient on their own. Teams are increasingly looking for tools that can:

• Surface insights across AI-driven SERPs
• Track visibility beyond clicks
• Integrate with broader marketing and data systems

That evolution is likely contributing to replacement activity — even as overall stability increases.

AI is reviving custom-built SEO tools

One of the more notable trends in the 2025 survey is the resurgence of homegrown solutions, including for SEO workflows.

Replacing commercial martech tools with homegrown applications accounted for:

• 8.1% of replacements in 2025
• Up from 3.4% in 2024 and 5% in 2023

This marks a meaningful shift after years of near-total reliance on commercial platforms.

“AI-assisted coding is changing the calculus of build vs. buy,” said martech analyst Scott Brinker. “It’s easier and faster to build than ever before. Companies should still buy applications where they have no comparative advantage. But in cases where they can tailor capabilities to differentiate their operations or customer experience, custom-built software is an increasingly attractive option.”

For SEO teams, this could mean more organizations building:

• Custom data pipelines.
• Proprietary SERP tracking systems.
• AI-driven analysis tools tailored to their specific needs.

Other martech categories show even greater stability

While SEO tools led in total replacements, the broader martech landscape is becoming more stable.

Several major categories saw declining replacement rates in 2025, including:

• CRM platforms (down more than 12% year over year)
• Marketing automation platforms
• Email distribution tools
• Content management systems

This suggests that many organizations are settling into core systems while selectively updating areas — like SEO — that are changing faster.
