Listen to the TLDR Audio Description.

On a normal morning in Texas, a law firm in Houston checks leads and sees fewer calls. A clinic in Tyler sees fewer patient forms. A restaurant in Lindale sees fewer reservations. Overnight, search changed.

The September 2025 Google Core Update rolled out in mid to late September and many sites felt it. Some lost up to 32 percent of clicks when AI answers replaced traditional results. Google is not a phone book. It is a living system that adapts.

At Bailes + Zindler, we built our approach around AI Search Optimization, also called AI SEO. The future is not ten blue links. It is AI Overviews, Bing Copilot, and generative answers.

This guide explains:

What changed in the September 2025 update
How East Texas and Houston businesses were hit
Why AI SEO is the recovery path
A checklist to start fixing it now

1. What Really Changed

Google did not just tweak settings. It changed how results are chosen.

Three shifts stand out

Helpful Content is now core
Google integrated the Helpful Content system into its core ranking systems. Real expertise, proof of practice, and results matter more than polished words.
AI Overviews expanded
Summaries at the top now answer many queries without a click. If the AI summary does not pull from your site, you become invisible.
Evidence and schema matter more
Structured data like LocalBusiness, Service, Review, and FAQPage is a ranking currency. Search engines and AI trust what they can verify.

The lesson is clear. Ranking now requires machine-readable proof, schema-backed evidence, and AI-ready content.

2. Local Fallout in Texas

Here is how the update played out close to home.

Retail in Lindale
A shop lost ground because product pages lacked reviews. Competitors with review schema held position and surfaced in AI Overviews.

Law firms in Houston
Generic copy like “we fight for justice” fell flat. Google and Texas Bar standards both push for clear, factual claims. Law firm SEO now needs verdicts, case types, years in practice, attorney bios, and plain-English FAQs.

Restaurants in Houston
Menus hidden in PDFs or images were ignored. Restaurants that coded menus with schema, including items and dietary details, rose in “near me” and AI Overviews.

Healthcare in Tyler
Sites without insurance details or procedure FAQs lost visibility. Patients ask specific questions like “Does this clinic take BlueCross?” and “How long is recovery after knee surgery?” If your site does not answer, AI will cite someone else.

Steps forward

Add evidence with schema
- Law firms: LegalService with years in practice and case types
- Healthcare: MedicalBusiness with accepted insurance and procedures
- Restaurants: Menu / MenuItem for dishes, prices, and dietary info
Personalize calls to action
Use local proof. A Houston firm should reference Harris County verdicts. A Tyler clinic should list accepted networks.
Build conversational Q&A pages
Match how people speak to rank in AI Overviews:
- What is recovery time after spinal surgery
- How much does pool service cost in Tyler
- Where is the best brunch in Houston

4. The Recovery Checklist

Do these now:

Check Google Search Console for drops starting mid September
Add LocalBusiness and Service schema with reviews, awards, author bios, and accepted insurance
Add plain-language FAQs written for a ninth grade reading level
Strengthen internal linking (for example, “Houston car accident lawyer” → “Personal Injury Law”)
Publish weekly posts so AI Overviews have fresh, citable facts
Fix technical SEO: broken links, image compression, speed, redirects

5. Why AI SEO Wins

Traditional SEO was about ranking for keywords. AI SEO is about being chosen as the answer.

It depends on:

Clean schema and machine readability
Verified trust signals (reviews, case results, insurance)
Conversational, local page design
Clear proof of authority on every page

This is often called Generative Engine Optimization. Structure, trust, and author credibility now decide visibility for Houston SEO and East Texas SEO.

Conclusion: Winners and Losers

The update created two groups. One proves value in machine-readable ways. The other does not.

Losers rely on vague copy and PDF menus.
Winners adapt and build for AI.

If your Houston law firm, Tyler healthcare practice, or Lindale restaurant saw traffic fall, do not wait for a bounce back. The way forward is AI SEO and the habits that support it.

At Bailes + Zindler, we guide East Texas and Houston businesses through this shift. With AI Search Optimization, recovery is possible and sets the stage for growth.

FAQs

What is a Google core update?

A broad change to how Google ranks pages. It affects many sites and focuses on overall quality. Google recommends reviewing content and measuring changes after the rollout finishes.

Why did my traffic drop even if I still “rank”?

AI Overviews can answer without a click. Studies show clicks fall when an AI summary appears, even if rankings look similar.

Will adding schema really help?

Schema does not guarantee rankings, but it gives AI and search engines verifiable facts. That raises trust and improves your chances to be cited in AI Overviews.
