An older WordPress site, modernized for AI search with no redesign
A Decatur family practice has an older WordPress website. It still looks the way it did before July 2026: same colors, same layout, same logo. If you put a screenshot from June next to one from October, you would struggle to spot a difference.
What changed is everything Google and AI tools read behind the page. Starting July 23, 2026, we rebuilt the site's headings, titles, descriptions, image labels and structured data, then added 50 new pages. No redesign, no new theme, no move to a new platform.
This post explains what we changed, why each piece matters, what the numbers show, and where they stop proving anything. If you own a business with a site that is "fine but old," this is the cheapest path we know to making it readable for Google Maps, AI Overviews and AI assistants.
Why the look of your site isn't the problem
Customers increasingly get their answer before they reach your website. Pew Research Center (July 22, 2025, browsing data from 900 U.S. adults in March 2025) found people clicked a traditional result on 8% of visits when Google showed an AI summary, versus 15% when it did not. They ended the browsing session on 26% of visits with a summary, versus 16% without.
So the question for an older site is not "does it look modern?" It is "does it give Google and AI tools clear, accurate material to build an answer from?" A handsome page that says "Services" in a decorative font and hides the details in an image gives them nothing. A plain page with a clear heading, a specific title and a matching data record gives them a lot.
That is the idea behind our Search Everywhere work: the Google Business Profile is the front door, and the website is the source of truth that tells Google what is behind it. You can read the full study in what three North Alabama businesses taught us about search in the AI era.
One note on method before the details. This was an observational study of three DIWYM clients, not an experiment. We did not hold anything constant, and we can't separate any single change from the others.
What the practice's site looked like before
When we audited the site on July 23, 2026, here is what Google and AI tools had to work with:
No structured data at all.
No meta descriptions.
Broken heading structure on 19 of the 26 pages we checked.
None of the 19 images on the homepage had alt text.
One page that covered every service.
No pages for the towns patients come from.
Outdated public files.
None of that was visible to a patient. All of it was visible to a crawler. This is common on older WordPress sites: the page looks finished to a human while the layer underneath is thin or wrong.
What we changed, and why each piece matters
1. Headings that describe the page
A heading is a label that tells a reader, and a crawler, what a section is about. On 19 of the 26 pages we checked, the heading structure was wrong. We rebuilt it so each page has one clear main heading and logical subheadings.
Why it works: AI tools and search engines pull answers from sections. A section with a clear heading above it is easier to lift into an answer, and easier for Google to match to a question.
2. Titles and meta descriptions
The title is the blue link in Google. The meta description is the short summary that often sits under it. Before, the site had none of the second and generic versions of the first. We wrote a specific one for every page.
Why it works: it is the first thing a person sees, and it tells Google what the page is for. Google may rewrite a description when it thinks another snippet fits the search better, so it's not a guarantee, but a good one gives it something accurate to start from.
3. Alt text on images
Alt text is a short written description attached to an image. None of the 19 homepage images had it. Alt text helps people using screen readers, and it tells search tools what a picture shows.
Why it works: it is the only way a crawler can "see" a photo. It is also an accessibility basic, and you should do it for that reason alone.
4. Structured data (schema)
Schema is a block of code, invisible to visitors, that states facts about your business in a format machines read directly: the business type, address, phone, hours, services and the areas you serve. Google Search Central describes structured data as giving "explicit clues about the meaning of a page."
Before July 2026 the site had none. Afterward, all 80 pages carried a medical practice record (the type is MedicalClinic) with hours and a catalog of eight services. Our audit on October 15, 2026 found 62 pages with FAQ markup, and the questions on each match the text visible on the page. That match matters: Google's "AI Features and Your Website" page (last updated December 10, 2025) says structured data should match the visible text.
We covered how to read this code in rich schema in plain English.
Why it works: instead of making a crawler guess which numbers on the page are your hours, you hand it the hours in a format it can't misread. It also gives the Business Profile and the website a second place to agree with each other.
5. A page for each service, plus the pages patients look for
The old site had one page for every service. We built 10 service pages, plus Insurance, New Patients and FAQ pages, then 8 city pages and 29 articles answering patient questions. That is the 50 new pages.
Why it works: a person searching for a specific service wants a page about that service. One page for everything can't be the best answer to any of them. The city pages are covered in city pages done right, and service pages in giving Google the details customers ask about.
6. A clean sitemap and an index check
A sitemap is a list of your pages that helps Google find them. We confirmed Google could actually index the new pages. On October 14, 2026, URL Inspection showed all 50 new pages as "Submitted and indexed."
Why it works: a page Google has not indexed can't appear in search at all. It takes a minute to check and it is where most "why isn't my new page showing up?" questions end.
7. An llms.txt file and open crawlers
We published an llms.txt file (a plain summary of the site for AI tools) and confirmed AI crawlers weren't blocked. Google says no special file or markup is required for AI Overviews or AI Mode, so treat this as a low-cost courtesy, not a ranking factor.
The timeline, in four days and three months
The technical foundation was done in four days after July 23, 2026. The 10 service pages and the Insurance, New Patients and FAQ pages went live July 29. The 8 city pages followed July 30. The 29 articles were published from August to October.
What the numbers show, and what they don't
Here is what we measured, with the windows.
Pages that appeared at all. Comparing six weeks in spring (March 30 to May 10, 2026) with six weeks in fall (August 31 to October 11, 2026), the number of pages with at least one Google impression went from 16 to 76. Search Console has no data for this site from May 14 to July 25, 2026, so the "before" window ends May 10 and we do not use that gap anywhere.
Impressions from searches without the practice's name. Over the same two six-week windows, these rose from 4,678 to 6,385 (+36%). Impressions per day rose from 318 to 394 (+24%).
Year over year. For July 23 to October 14, 2026 against the same dates in 2025, impressions rose from 26,782 to 36,377 (+36%), and the number of different searches the site appeared for rose from 970 to 2,260 (2.3 times). The 2026 window has 81 days of data against 84 in 2025, so the comparison, if anything, undersells the change.
Clicks were flat. Over that same year-over-year window, Google clicks went from 2,154 to 2,120 (−2%). In the six-week spring-versus-fall comparison clicks rose from 1,002 to 1,114 (+11%), but that compares different seasons, so we do not lead with it. The honest summary is that Google showed the practice's site much more often and people did not click it more often. That pattern matches what the national research describes, and we cover it in seen more, clicked less.
The new pages. From launch to October 12, 2026, the 50 new pages together drew about 15,200 impressions and 78 clicks. These are page-level figures: they can overlap, and we never add them to the site's total impressions above. The clicks are small. We are not claiming patients.
What we can't say
We can't say that structured data, or any one fix, caused these results. The schema launched at the same time as the new pages, the new content and ongoing Business Profile work, and we can't pull them apart. Spring and fall are different seasons. The 2025 half of the year-over-year window includes days before Google's September 2025 reporting change, when impressions were inflated, so that comparison likely understates the 2026 gain. We never use average position across that change. And a rise in impressions is not a rise in appointments: we have no data on patients and make no claim about them.
Our read, which is an interpretation and not a measurement, is that the older site was invisible for most of what patients search because Google had little to work with, and that giving it more to work with widened the set of searches it could appear for.
What you can check on your own site today
Check your headings. Open a page, right-click and choose Inspect, or use a free browser extension that outlines headings. Each page should have one main heading and subheadings in logical order.
Check alt text. Hover over your homepage images in your WordPress media library and see which have an alt text field filled in.
Search your own page titles. Search Google for your business plus a service. If the title in the result is generic ("Home" or "Services"), the title needs work.
Look for structured data. Paste a page address into Google's Rich Results Test. If it finds nothing, or only a generic business type, you have room to improve.
Check indexing. In Google Search Console, paste a new page into the URL Inspection box. You want "Page is indexed."
Compare with your profile. Make sure the hours, phone and address on your site match your Google Business Profile. The five minute consistency check walks through it.
If you are a dentist, a med spa, a home service company or any business whose site predates AI search, the same pattern is likely to apply: the site looks fine, and the layer underneath is thin. We haven't measured those industries ourselves, so treat this as a reasonable place to start, not a promise.

Frequently asked questions
Can I make my old WordPress site work for AI search without a redesign?
Yes. In the practice's case, the visual design stayed the same. We changed headings, titles, meta descriptions, alt text and structured data, and added service, city and question pages. Those are the parts Google and AI tools read. Whether a redesign is worth doing for other reasons, such as speed or a clearer booking flow, is a separate decision. For AI search, readable structure and accurate details matter more than a new look, and they can be fixed on the site you already have.
What is structured data, and does my site need it?
Structured data (also called schema) is code that states facts about your business, such as type, address, hours and services, in a format machines read directly. Google says it gives explicit clues about a page's meaning and can enable richer results, though it doesn't guarantee them. It also says no special markup is required for AI Overviews. We add it because it removes guesswork and gives your website a second way to match your profile.
How long did the changes take?
The technical foundation took four days, starting July 23, 2026. The service, Insurance, New Patients and FAQ pages went live July 29, the eight city pages July 30, and the 29 articles were published from August to October. In the fall 2026 window, 76 pages had Google impressions, up from 16 in spring. Expect weeks, not days, for Google to show new pages, and check indexing first.
Did the changes bring more clicks or patients?
Not clearly. Year over year (July 23 to October 14, 2026 versus 2025), the practice's impressions rose 36% and clicks were flat at 2,120 against 2,154. We have no data on patients and make no claim about them. Google showed the site far more often; that is what we measured. We can't separate any one change from the others, so please read these results as one practice's story.
Is FAQ markup worth adding?
For its own sake, mostly no. Since August 8, 2023, Google limits FAQ rich results to well-known authoritative government and health sites. We still mark up questions on the practice's pages because it states answers precisely, and each answer matches the visible text on the page. Don't add FAQ markup expecting a special display in search; add it because stating a clear answer once, in both places, is good practice.
What if my site is on Wix or Squarespace instead of WordPress?
The principles are the same: clear headings, specific titles and descriptions, alt text, accurate structured data and a page for each service. The tools differ. Our study's two Wix sites show the range: one carries rich markup on all 18 pages, while the other has only Wix's automatic markup on its homepage. Check what your builder adds automatically before assuming it is enough, because automatic markup is often only a basic business record.
Do I need an llms.txt file?
Not to appear in Google's AI features. Google says no special file or markup is needed for AI Overviews or AI Mode. We publish one for the practice as a low-cost courtesy, and none of the three sites we audited block AI crawlers. Treat it as optional housekeeping that costs little, not a ranking lever, and put your effort into clear pages and accurate details first.
