Should you avoid SEO agencies that promise to get you to the top of Google?

Why does Google warn against ranking guarantees?

John Mueller's statement aims to protect advertisers in a market filled with unrealistic promises. Specifically, no SEO outside of Google can guarantee a specific position in search results. The ranking algorithms involve more than 200 public criteria and hundreds of undocumented ones, with weights varying by sector, query, user intent, and location.

Agencies promising number one rankings typically rely on three mechanisms: they either target ultra-specific queries with no volume (it’s easy to be first on a query typed three times a month), use black-hat techniques (PBN, link spam, cloaking) that work temporarily before being penalized, or rely on client ignorance by rephrasing their contracts to escape refund clauses.

Is this warning aimed only at small, dubious agencies?

No, and this is an important point. Google makes no size distinctions. Some established firms that are well-ranked continue to display ranking guarantees in their commercial offers because it converts better with clients who are unfamiliar with SEO. Mueller explicitly targets this practice regardless of the agency's size.

The challenge for a practitioner is to spot the red flags: a contract mentioning guaranteed positions, promises of results in less than three months on competitive queries, or a refusal to detail the methods used. A serious provider will talk about gradual visibility, qualified traffic goals, conversion rates, not fixed rankings.

How does Google define acceptable SEO practices?

Google has never published a comprehensive list, but its Help Center outlines red lines: link manipulation, automated content with no value, satellite pages, cloaking, misleading redirects. Anything that attempts to manipulate rankings instead of genuinely improving user experience is considered dubious.

Legitimate methods rest on three pillars: solid technique (crawlability, performance, clean indexing), quality content aligned with search intent, and authority built through natural and relevant links. None of these components can guarantee a specific position, but their combination statistically enhances performance in the medium term.

• No external provider controls Google's algorithm, so none can guarantee a specific position.
• Top 1 guarantees often depend on queries with no real volume or temporary black-hat techniques.
• A serious contract mentions goals for qualified traffic, visibility, and conversion, not fixed positions.
• Google considers any manipulation intended to deceive the algorithm rather than improve user experience as dubious.
• Google's Help Center remains the reference for distinguishing acceptable practices from risky techniques.

Is this statement consistent with observed practices in the field?

Absolutely, and it’s even a necessary reminder. The SEO market is still polluted by players who sell empty promises through convoluted contracts. Serious agencies have known for a long time that one cannot guarantee a position: instead, they build a visibility strategy with measurable KPIs (organic traffic, pages in the top 10, share of voice on strategic queries, engagement rates). No field expert promises a number one ranking to an informed client.

The problem is that this practice persists because it works commercially. Uninformed clients prefer to hear, "we guarantee the first position" rather than, "we will work on your thematic authority over 12 months with measurable progress goals." Agencies that play this game take a calculated reputational risk: if it works temporarily, the client is happy; if it fails, they hide behind vague contractual clauses.

What nuances should we add to this recommendation?

There are cases where an agency can estimate with high probability a top 3 or top 5: ultra-targeted local queries with low competition, immature B2B niche markets, situations where the client already has strong domain authority, and only simple technical optimizations are needed. But even in these cases, a professional will speak of high probability, not contractual guarantees.

Another nuance: some agencies offer conditional refund plans if specific goals are not met (like "X% increase in organic traffic in 6 months or a refund"). This is not the same as a position guarantee and is more defensible, provided the goals are realistic and the methods used are transparent. However, even in this case, one must read the clauses: some plans exclude algorithmic penalties, budget cuts, or changes in client strategy, making refunds nearly impossible.

In what situations does this rule not really apply?

The question is poorly posed: the rule always applies, but the level of risk varies. If you are a local SMB hiring an agency to rank for "plumber [town of 5,000 inhabitants]," the risk of a top 1 promise is low because the competition is nearly non-existent. The provider can technically guarantee this without black-hat methods.

But beware, even in this case, Google can change the way results are displayed (integration of Google Business Profile, local featured snippets, changes in query intent). A fixed position remains an algorithmic fiction. An informed practitioner knows that even for low-competition queries, results fluctuate based on user context (precise location, search history, device). A guarantee remains commercially dubious, even if technically feasible.

What should you do before signing with an SEO agency?

Request a transparent and detailed audit of your site before any commitment. A serious agency invests time to understand your market, analyze the competition, identify opportunities, and technical barriers. If the salesperson promises the number one spot in the first conversation without having looked at your site, run away. A serious diagnosis takes several days, not 30 minutes over the phone.

Ask for verifiable references and speak directly with former clients. Don't settle for embellished case studies on the agency's website. Ask specific questions: what methods were used? Did the results last over time? Were there any algorithmic penalties? How did the agency handle traffic drops or algorithm changes? A provider that refuses this level of transparency is likely hiding dubious practices.

What mistakes should you avoid when selecting an SEO provider?

Never choose based on the lowest price. Quality SEO requires expert time, expensive tools (Ahrefs, SEMrush, Screaming Frog, etc.), and constant monitoring. An abnormally low price indicates mass outsourcing to low-cost writers or risky automated techniques. A competent SEO costs between 800 and 2000 euros per day depending on expertise and region.

Avoid agencies that promise quick results (less than 3 months in a competitive market). Organic SEO takes time: Google needs to crawl changes, recalculate authority, and observe user behavior. The only exceptions involve major technical fixes (non-indexable site, massive 404 errors, severe cannibalization) that unleash existing potential. Even in these cases, we talk about gradual improvement, not instant miracles.

How can I verify that my agency is using acceptable methods?

Request a detailed monthly report documenting every action: on-page modifications, links created (with source URLs), published content, technical optimizations. A legitimate provider has nothing to hide and can justify every line of work. If the reporting remains vague ("content optimization," "improvement of link profile") without actionable details, that’s a red flag.

Regularly check your backlink profile via Google Search Console, Ahrefs, or Majestic. If you see hundreds of links from sites unrelated to your niche, in foreign languages, or with over-optimized anchors, your agency is probably using a PBN or buying links in bulk. Confront them immediately and demand a disavow if necessary.

• Demand a detailed audit BEFORE signing, not a vague commercial promise.
• Check client references directly, not just through the agency's case studies.
• Refuse any contract mentioning a guarantee of number one position or top 3.
• Request a transparent monthly report detailing actions taken.
• Monitor the backlink profile every month to detect dubious links.
• Favor measurable objectives (qualified traffic, conversions, share of voice) rather than fixed positions.
