SEO software shows a company how its website appears in search and what to change: which keywords it ranks for, what is broken on the site, what content to write. In these interviews buyers use it nearly as often to watch competitors as to watch themselves, and about one in five use it for work that is not organic search at all. In these interviews companies under $100M in revenue name an SEO tool about as often as companies over $10B, unlike CDPs, CRMs or testing tools, which the largest companies name far more often. That measures the tools interviewed companies report, not adoption across the whole market. What size changes is the kind of tool.
What is SEO software?
SEO (search engine optimization) software helps a company see and improve how its website appears in search results. It tracks rankings and keyword demand, crawls the site for technical problems, guides content and shows where competitors rank; increasingly it also tracks how the brand appears in AI-generated answers. Buyers describe the suites as bundles of these jobs — one consumer services company's SEO manager has “used SEMrush for all my keyword research, for competitor analysis, keyword gap, position ranking tracking, and to track backlinks and content gap.”
The interviews add what the bundle is actually used for. Tracking your own rankings is the most common job, but watching competitors is close behind, and for about one in five companies the tool serves work outside organic search — paid-search keywords, market demand, the words customers use for a product.
The second finding is about who runs it, and it only shows up against other categories:
In these interviews, naming an SEO tool does not grow with company size. A company under $100M in revenue names one about as often as a company over $10B, while CDPs, CMSs, CRMs and testing tools are named two to four times as often at the top; SEO tools share the flat line of web analytics, which every website needs whatever its size. The smaller companies in these interviews are ones that talk to us about their marketing technology, so this is a comparison within the interview set, not a census of small businesses.
What changes with size is which kind. Enterprise SEO platforms are about one in ten of the SEO-tool companies under $100M and more than two in five of those over $10B, while self-serve suites are named at every size.
What is the difference between an SEO suite and an enterprise SEO platform?
A self-serve SEO suite — Semrush, Ahrefs, Moz — is a research and tracking tool a marketer can buy alone and point at any site, including competitors'. An enterprise SEO platform — BrightEdge, Conductor, Botify, seoClarity — is a contract built around one large site, with deeper crawling, reporting for many stakeholders and usually an account team. A crawler such as Screaming Frog does one technical job. A fashion brand's ecommerce director describes what the platform covers: “So there are the two places of SEO where it's technical and then it's also content related, and it helps with both.”
One buyer puts the limit plainly. A children's brand says of its enterprise platform: “Conductor is the software tool that is showing you how your organic is doing. But they're just not strategy.” That the platform still needs an SEO person is a lesson on what SEO buyers wish they'd known, and the price gap between the two kinds is on what buyers actually pay for SEO tools.
The split follows the business as well as the size. Among companies with an SEO tool, about one in three consumer brands name an enterprise platform, against fewer than one in ten B2B companies, which mostly run suites. The difference between SEO tools and AI-visibility tools is a separate question, covered on what is answer engine optimization.
Suite, enterprise platform, crawler, Search Console
A suite is self-serve research and tracking across any site. An enterprise platform is built around your own large site, sold on contract. A crawler audits a site's code and structure. Search Console is Google's free record of how your own site performs in its results.
Who uses SEO software?
Mostly marketing, ecommerce, digital and growth leads, with SEO specialists where a company has them. Fewer than one in ten of the interviewees whose stack names an SEO tool hold an SEO or search title, which is ordinary for a marketing tool: analytics and BI tools look the same.
The tool also travels beyond the SEO team. In about one in four companies that describe their SEO tool, another team uses it too — paid search, brand teams, merchandisers, product-content writers, newsroom reporters. A global beauty group's growth marketer says “I don't actively use the tool. I know that the brand teams use it,” and a children's brand describes a platform where “Your paid marketing team can use it and your SEO team can use it”.
And agencies are part of the picture. About one in four companies that talk about SEO mention an agency in the same answer — about as often as for paid search or PR, and roughly twice as often as for email or social media. Where the agency holds the tool is another lesson on the SEO lessons page.
What is SEO software used for?
Among the companies that describe what they use an SEO tool for, seven jobs appear, most common first. A company can do several, so the shares overlap:
- Tracking its own rankings and keyword demand
- Watching competitors
- Tracking AI answers
- Guiding content
- Keeping the site technically healthy
- Reporting SEO results to the business
- Work outside organic search
Watching competitors is nearly as common as watching yourself. It is the job a suite adds over Google's free tools, which only see your own site.
Tracking its own rankings and keyword demand
Which keywords the site ranks for, how that moves, and how many people search each term.
A fashion brand uses its platform so “we can track keywords for organic search, to see how we improve or decline week over week, month over month, et cetera.” A specialty home retailer values “its ability to show how we are showing up in terms of search rankings, what keywords are important and are being searched on in terms of volume.”
Watching competitors
Their rankings, keywords, content gaps, share of voice and traffic.
A hospitality software company's media planner explains: “You're able to see, for example, what keywords your competitors are going after, understand their SEO strategy so that you can then shape your own”. A global apparel brand's head of search says Semrush “gives us a unique view into how we stack up against our competitors”.
Tracking AI answers
How the brand appears in ChatGPT, Google's AI Overviews and other AI answers, tracked inside the SEO tool. The share is across every year of interviews and counts companies that describe doing it, including some still trialling the module; it does not count buyers who only mention that the feature exists. Nearly all of them were interviewed in 2026, and none before 2025.
A consumer services company's SEO manager observes that “pretty much every SEO tool is rolling out with AI visibility features right now,” and a consumer software company's CMO says “BrightEdge is interesting because it tells us how we're ranking in the LLMs.”
Guiding content
What to write, and which words the pages need.
An eyewear brand's tool “also helps us to kind of prioritize what we should be building out from a content standpoint,” and a consumer-goods manufacturer uses Semrush for “making sure our PDP content has keywords that people are regularly searching.”
Keeping the site technically healthy
Crawling, audits, indexing and site migrations — the job crawlers specialize in.
A luxury brand's SEO manager calls Screaming Frog “our technical SEO auditing tool, and it enables us to conduct a comprehensive website crawl, analyze metadata, internal linking, redirects, and so on in a very quick way.”
Reporting SEO results to the business
Organic traffic, rankings and page performance, packaged for people who do not log in.
A large health insurer uses its platform “for tracking all of our SEO success, the traffic that we have coming in by keyword, pages that are performing well from an organic ranking standpoint.”
Work outside organic search
Paid-search keywords, sizing market demand, and learning the words customers use for a product.
A life-sciences company notes that with “Semrush you can do both SEO and SEM research.” At a large general-merchandise retailer, the team writing product descriptions watches the words shift: “last year they were calling something as snowblower versus this year, snowthrower is the number one ranking keyword.”
The order is the point. SEO software is bought as a way to improve a site's own rankings, but in practice it is as much a window on the market — on competitors, on demand, on the language customers use — and that is what the people outside the SEO team use it for.
Which SEO tools do buyers use?
Semrush is by far the most-named, followed by Ahrefs, Google Search Console, BrightEdge, Similarweb, Screaming Frog and Conductor. Ratings for these tools are on what SEO buyers wish they'd known, and where Semrush leavers go is on Semrush alternatives.
Alongside a suite or platform, buyers name single-job tools: crawlers, content tools, Google's own consoles. Similarweb is sometimes called an SEO tool, but buyers mostly use it to estimate competitors' traffic, often outside the SEO team — one growth marketer, asked whether it was an AI-visibility tool, answered “No, that's an SEO tool. It's not AEO at all.” Its competitive-research role is on what is competitive intelligence software.
Suites and platforms
Self-serve suites: Semrush · Ahrefs · Moz · SE Ranking · SpyFu · SISTRIX · Search Atlas
Enterprise platforms: BrightEdge · Conductor · Botify · seoClarity · Pi Datametrics
Single-job and adjacent tools
Crawlers: Screaming Frog · Lumar · Sitebulb · Siteimprove
Google's own: Search Console · Bing Webmaster Tools
Content: Clearscope · Surfer · MarketMuse. Competitive traffic: Similarweb. AI visibility: Profound · Scrunch · Peec AI
The structural finding sits underneath the list. Every company can buy a suite, and companies of every size do; the enterprise platforms are a purchase that larger consumer brands and regulated companies make around one big site. Comparing the two kinds on features misses that they are bought for different sites.
Where do the numbers in SEO software come from?
From several kinds of data, and knowing which is which tells you how far to trust a number. First, Google's own record of your site: Search Console and Bing Webmaster Tools report clicks, impressions and indexing, free, and only for your own site. A news publisher uses it “to review things like search clicks, impressions, indexing issues, page performance, search visibility, and whether content or technical issues may be affecting discoverability.”
Second, crawled data: the code and structure of your site, or anyone else's. A global sportswear brand's SEO director points out: “All the same data that we look at is often the same data that we can see on any of our competitors because we're crawling source code”.
Third, third-party search data, which comes in two forms. Keyword search volumes and competitors' traffic are modelled estimates built from outside datasets. Rankings are observed: the tool collects search results for particular queries, locations, devices and times. Both are what make competitor-watching possible, and neither is interchangeable with Google's own reporting or your analytics; buyers' warnings about the estimates are on the SEO lessons page.
The newest layer, AI-answer monitoring, is a fourth kind: the tool runs or collects a chosen set of prompts and records how often the brand appears in the answers. What it shows depends on the prompts, the AI platforms, the timing and the collection method, so it is a monitored sample of AI visibility, not a measure of what every user sees. How buyers judge it is on what AI-visibility buyers wish they'd known. Cost is on what buyers actually pay for SEO tools and the complaints on top complaints about SEO tools.

Start my checkup →Should you buy SEO software?
It depends which job you need done. Tracking your own site's search performance starts with Google's free tools; watching competitors and estimating demand is what buyers in these interviews pay a suite for.
Four things follow, and they are our recommendations rather than practices buyers describe. First, start from the job, not the category: own rankings and site health can begin with Search Console and a crawler, and a paid suite earns its place when you need to see competitors and demand. Second, let size shape the kind of tool, not whether you have one: a large single site with many stakeholders is where buyers name enterprise platforms, and a suite serves most others. Third, decide who will use it — in about one in four companies teams beyond SEO do, so plan seats and access for them. Fourth, if AI answers matter to you, test the suite's AI module before buying a second tool; the routes are on what is answer engine optimization.
Common questions
What is SEO software?
SEO (search engine optimization) software helps a company see and improve how its website appears in search results. It tracks rankings and keyword demand, crawls the site for technical problems, guides content and shows where competitors rank; increasingly it also tracks how the brand appears in AI-generated answers. In these interviews about half of companies that describe their SEO tool use it to track their own rankings, and about two in five to watch competitors.
What is SEO software used for?
In these interviews, most often for tracking a company's own rankings and keyword demand, then watching competitors, tracking AI answers, guiding content, keeping the site technically healthy and reporting results. About one in five companies also use it for work outside organic search, such as choosing paid-search keywords or learning what customers call a product.
What is the difference between an SEO tool and an enterprise SEO platform?
A self-serve SEO suite such as Semrush, Ahrefs or Moz is a research and tracking tool a marketer can buy alone and point at any site, including competitors'. An enterprise SEO platform such as BrightEdge, Conductor, Botify or seoClarity is a contract built around one large site, with deeper crawling and reporting for many stakeholders. In these interviews enterprise platforms are about one in ten SEO-tool companies under $100M in revenue and more than two in five over $10B.
Is Google Search Console enough for SEO?
Search Console is Google's own record of your site — clicks, impressions and indexing — and buyers use it for exactly that. It cannot see competitors or estimate demand beyond your own pages, which is what buyers in these interviews use paid suites for.
Can SEO tools track ChatGPT and AI Overviews?
Many now try. About one in three companies that describe what they use an SEO tool for say they track AI answers with it, some of them still on a trial; nearly all were interviewed in 2026. Buyers still judge those modules against dedicated AI-visibility tools.
Who uses SEO software in a company?
Mostly marketing, ecommerce, digital and growth leads, with SEO specialists where a company has them. In about one in four companies a team other than SEO also uses the tool — paid search, brand, merchandising, writers. And about one in four companies that talk about SEO mention an agency in the same answer.
Do small businesses need SEO software?
In these interviews, companies under $100M in revenue name an SEO tool about as often as companies over $10B, and they mostly use self-serve suites such as Semrush or Ahrefs; the enterprise platforms concentrate at the top. The smaller companies here are ones that talk to us about their marketing technology, so this compares interviewed companies rather than measuring small-business adoption.
