3. $600 to $1,000 Paid ads management a month, ad spend extra, Calgary providers

## We audited our own advice.

[Google says llms.txt does nothing for Search. We checked our own 84 posts.](https://fifteenthmeridian.com/blog/google-ai-search-guidance-audit-2026)

Google now says its Search ignores llms.txt and rejects chunking, writing for AI and extra schema. We ran a checker over our own 84 posts to see what survived.

1. 19 Call it optional, unproven or ignored by Google
2. 4 Implied it helps, all corrected on 2026-10-15
3. 0 Posts advising chunking, AI-specific writing, required schema or chasing inauthentic mentions, after a manual read
4. 11 Posts flagged by the other six rules: 11, none confirmed after a manual read; 2 of them off-topic misfires

## The AI Overview split.

[AI Overviews took over one category completely and left another untouched. We measured 38 search results pages.](https://fifteenthmeridian.com/blog/ai-overview-split-2026)

We pulled 38 Google results pages on one day. AI search tool queries returned an AI Overview 20 out of 20 times. Local service queries returned none: 0 out of 18, in both the US and Canada.

1. 20 of 20 AI search tool queries that returned an AI Overview
2. 17 of 18 Local service queries that returned a local pack instead

## Who owns the AI search tools category?

[We analyzed 330 results in the AI search tools category. Half of it is vendors ranking themselves.](https://fifteenthmeridian.com/blog/ai-search-tools-category-study-2026)

We pulled 20 US Google SERPs across the AI search tools category and classified all 330 organic results. Every query carries an AI Overview. 51.5% of results come from vendors selling a tool in the category they rank for.

4.2%

Calgary business homepages that block any AI crawler in robots.txt

**Sample**

403 Calgary business homepages, robots.txt found on 333

**Collected**

July 21, 2026

**Source**

First-party crawl

**Dataset**

333 rows × 9 columns

This study has no winner ranking. Every site is listed anonymized: block posture is reported without naming the business, because blocking or not blocking is a defensible business choice either way.

## The AI-blocking myth.

[403 Calgary sites later, almost no one blocks AI (and the ones who do picked wrong).](https://fifteenthmeridian.com/blog/ai-blocking-myth-calgary-2026)

We fetched robots.txt for 403 Calgary business homepages. Only 4% block any AI crawler. Most blocks target training bots, which do not stop live AI citation.

1. 2% Block a live-retrieval bot, the kind that fetches a page to answer a question
2. 6 sites Block every crawler by accident with a wildcard rule
3. 70 of 403 Have no robots.txt at all
4. 2 of 2 Popular blocking rules that do not do what the advice claims. GPTBot does not remove a site from ChatGPT answers and Google-Extended does not remove it from AI Overviews, according to each operator’s own documentation

## Broken schema in Calgary.

[72% of Calgary sites have structured data. Only 61% told search engines they’re a business.](https://fifteenthmeridian.com/blog/broken-schema-calgary-2026)

We parsed 403 Calgary homepages for tel: links, forms, and booking widgets. 41% cannot be phoned in one tap from mobile. Dentists lead. Cafes bottom.

1. 97% Dental practices with a tappable phone number, the best vertical
