If you already have an SEO agency, this is uncomfortable to read. Not because it's your fault — but because 90% of SEO agencies in Mexico still work with 2019 methodologies. They're optimizing for a Google that no longer exists. Meanwhile, your potential customers are getting answers from ChatGPT and Perplexity where your competition shows up and you don't. This article isn't about changing agencies tomorrow. It's about knowing the right questions to ask.
The 5 questions you should ask your agency today
"Do you have a specific strategy for us to appear in ChatGPT and Perplexity?"
If the answer is confusing, evasive or they don't know what you're talking about: there's a serious problem. In 2026, any competent SEO agency should have a clear answer on GEO.
"Does our site have Schema.org implemented and validated?"
Schema.org is the technical foundation of both AEO and GEO. If your agency hasn't implemented Organization, Service and FAQPage, they're working with one hand tied behind their back.
"How do we measure our presence in Google AI Overviews?"
If they're not measuring it — not even tracking it — they're ignoring one of the most significant changes in search behavior in recent years.
"Are you generating content with semantic intent or just for keyword volume?"
Industrially generated content to "stuff keywords" no longer works like in 2018. Google and LLMs reward content that shows real expertise and answers specific questions with depth.
"What is Entity Authority and how are we building it?"
This single question will tell you everything. An agency that does GEO knows exactly what Entity Authority is and has an articulated answer about how to build it for your industry.
Why most agencies don't do GEO
It's not malice — it's inertia. Traditional SEO worked very well for 10 years. Many agencies developed effective processes for that world and have reasonably satisfied clients with rankings reports that look good. They have no immediate incentive to invest in learning something new.
The problem is that Google position rankings are no longer the only — or the most important — organic search channel. A site that sits in position 3 on Google but is invisible on ChatGPT is losing a growing share of the market its rankings reports aren't even measuring.
What a modern SEO strategy must include in 2026
- Full technical SEO: speed, Core Web Vitals, pre-rendering for AI crawlers, correct error handling
- On-page and semantics: content oriented to real search intent, not just keyword density
- Complete Schema.org: Organization, Service, FAQ, LocalBusiness validated and up to date
- GEO strategy: content that LLMs can cite, Entity Authority building, data consistency
- AEO: structuring for featured snippets, Google AI Overviews and voice assistants
- Integrated measurement: Search Console, AI Overviews monitoring, AI-mention tracking
The cost of not updating
Companies that invest in GEO and AEO today will accumulate a hard-to-reverse advantage. LLMs are biased toward sources they already know and trust. A brand that builds Entity Authority today becomes increasingly hard to displace — even for competitors with more resources who arrive late.
It's not alarmism: it's simply how machine-learning systems work. The first mover has a real advantage. And in the Mexican context, where most companies still aren't working on this, the opportunity is genuine.
How to evaluate if you need to change strategy
We're not telling you to switch agencies tomorrow. We're telling you to evaluate whether your current investment covers the full search spectrum. There are three possible scenarios:
Your agency does quality technical and on-page SEO
They can be enough as a foundation. Consider complementing with a specific GEO and AEO strategy, either in-house or with a specialist.
Your agency does basic SEO (meta tags, keywords, ranking reports)
It's time to have a direct conversation. Ask them to present a proposal on how they're going to tackle GEO and AEO. Their answer will tell you if they're ready for the current ecosystem.
Your agency doesn't know what GEO or Entity Authority is
That's enough information. It doesn't mean they're a bad agency for other things, but for search positioning in 2026 you need specialized support.
A final thought
SEO has always been a rapidly evolving discipline. The agencies that survived the Panda, Penguin and Hummingbird updates were the ones that adapted ahead of the market. GEO and AEO are the next evolution. The difference this time is that LLMs are changing the search ecosystem more deeply and faster than any previous algorithm update.
