How can you assess whether third-party SEO advice, tools, and services are right for you?

When evaluating third-party SEO advice, tools, and services, focus on whether they can help you do your work, what evidence supports their claims, and whether they follow the official guidelines of the search service you are targeting. The supplied material primarily concerns Google Search: some external services may be helpful, but using tools does not guarantee better rankings, and tool-generated predictions are not Google’s internal ranking data. Before adopting recommendations, distinguish between experience-based opinions, official guidance, and promises of results. In particular, do not make major website changes based solely on a single audit report.

Check the basis for the advice, then assess where it applies

Google’s guide to third-party resources states that good advice offers opinions grounded in data or experience, or cites official guidelines to support its claims. This does not mean that only official documentation is worth consulting. Rather, a provider’s speculation should not be presented as “this is how Google ranks websites.”

• Claims based on experience: Recognize them as experience-based judgments, not rules that apply to every website.
• Claims of official support: Check whether the cited material actually supports the recommended approach.
• Advice involving AEO or GEO: If you are targeting Google’s AI search experiences, also check the advice against its guidelines for generative AI optimization. A new service label does not remove the need for verification.

A tool’s practical value does not mean it has the answers to rankings

Generating sitemaps, helping create content, and suggesting improvements are all possible uses of third-party tools. But “helping you get work done” and “guaranteeing search performance” are two different things. Google explains that third-party tools cannot access its internal ranking data, and their own predictions may not come true. Claims of access to Google’s “internal” metrics or guarantees of ranking improvements warrant extra caution.

Whether or not you use third-party tools, Google strongly recommends also using Search Console to obtain important information and data directly from Google Search. This recommendation does not mean that all third-party data is worthless. What you should avoid is mistaking a tool’s own data or predictions for Google’s internal data or a promise of results.

When evaluating providers, ask what they plan to change and why

For example, if a provider recommends major website changes based on a tool-generated audit, first ask them to explain the basis for those recommendations, then check them against official guidance. Google’s hiring guide also calls for evaluating the tools and recommendations an expert uses, rather than simply looking at how many issues a report lists.

• Do they cite official documentation to support their recommendations, and do their tools and methods comply with the relevant guidelines?
• Are they willing to explain the measures they plan to take and the changes they make to your website?
• Do they claim to be approved by Google, have a special relationship with Google, or guarantee a number-one ranking?

Google does not evaluate or endorse third-party SEO tools, nor does it evaluate third-party services, so claims of this kind of “official recognition” should not be a reason to buy. Outsourcing does not transfer responsibility, either: website owners still need to understand what the company they hire is doing and cannot ignore the risks of misleading practices simply because a provider is doing the work on their behalf.
