Case Study, Part 1 of 2 — Baseline Recorded
We wrote down every number before we touched anything
Motor Parts + is a family-run engine remanufacturer and full-service auto machine shop in Kaufman, Texas, building Cummins diesel long blocks and cylinder heads and shipping them nationwide. A new website is finished and waiting to launch. Before it goes live, we measured the starting line: website structure, structured data, social reach, search rankings, AI answer-engine visibility, and review signals.
This page is the “before.” The “after” gets measured the same way, with the same queries, on December 19, 2026 — and published right here beside it.

The Point of This Page
Most case studies only show the good half
You have seen the pattern: an agency publishes a chart with an arrow going up and no verifiable place where the line started. It is easy to write because nobody wrote down the “before.”
So we did it in the other order. Every figure below was captured on one date, before launch, using checks that can be repeated by anyone — reading the live pages, running a fixed list of searches, and pulling the business’s own verified Google profile. In roughly three months we re-run the identical checks and publish both columns. If a number does not move, it will say so.
Baseline — September 19, 2026
The starting line, in five numbers
Baseline 1 — Website & Technical Foundation
Eight pages, and almost nothing a machine can read
The current site is a hosted brochure builder. It loads, it looks tidy, and it tells a search engine or an AI assistant remarkably little about what this shop actually sells.
| What we checked | Baseline | Status |
|---|---|---|
| Indexable pages in the sitemap | 8 | Thin |
| Structured data (schema) entities — LocalBusiness, Product, Service, FAQ | 0 on every page | Missing |
| Pages with a subheading structure (any H2) | 0 of 8 | Missing |
| Pages with a main heading (H1) | 7 of 8 — the Contact page has none | Partial |
| Images carrying descriptive alt text | 60 of 106 (46 missing) | Partial |
Social share image (og:image) | 0 of 8 pages — links preview with no image | Missing |
| Title tags and meta descriptions present | 8 of 8, phone-number-led | Present |
| Product or engine pages a buyer can browse by year, make and model | 0 | Missing |
| Published pricing, warranty terms or freight estimates | Warranty page only; no prices, no freight guidance | Partial |
| Online quote or lead-capture path tied to a specific engine build | None — phone only, plus a pop-up on every page load | Missing |
Why the zero on schema matters most
Structured data is how a website states facts in a format software can quote: this is the business, here is the address, these are the engines, this is the price, this is the warranty. With none of it present, every search engine and every AI assistant has to infer the whole business from paragraphs of prose — and when it is not confident, it names a competitor that spelled it out instead.
Baseline 2 — Search Rankings
Unbeatable in Kaufman. Invisible everywhere else.
Ten commercial-intent searches, run on one day. The pattern is clean: add “Kaufman” and the shop owns the page. Take it away and the shop disappears — even though it ships engines nationwide.
| Search query | Intent | Baseline position |
|---|---|---|
| engine machine shop kaufman texas | Local | #1 — plus 4 more listings in the top 10 |
| cummins engine overhaul kaufman tx | Local | #1 — 3 listings in the top 10 |
| auto parts store kaufman tx | Local | #7 — behind O’Reilly, AutoZone and NAPA |
| cummins engines for sale texas | Regional / commercial | Not in top 10 |
| remanufactured cummins 5.9 long block | National / commercial | Not in top 10 |
| cummins long block for sale | National / commercial | Not in top 10 |
| 5.9 cummins cylinder head rebuild | National / service | Not in top 10 |
| remanufactured diesel engines dfw | Metro / commercial | Not in top 10 |
| diesel engine remanufacturer near dallas | Metro / commercial | Not in top 10 |
| engine rebuild dallas texas | Metro / service | Not in top 10 |
Three of ten. And the three wins are all searches that already contain the town name — meaning they mostly capture people who know the shop exists. The seven misses are where someone with a blown 5.9 and a credit card is shopping, and on every one of those the results are filled with national resellers and out-of-state rebuilders.
Baseline 3 — AEO & GEO (AI Answer Visibility)
Zero mentions inside AI answers that matter
Ranking in a list of links and being named inside an AI-generated answer are two different scoreboards. This is the second one.
| Signal | Baseline | Status |
|---|---|---|
| National commercial-intent queries where AI answers cite the domain | 0 of 7 | None |
| Local Kaufman-qualified queries where the domain is cited | 3 of 3 | Strong |
| Machine-readable business entity (LocalBusiness / AutoRepair schema) | Not published | Missing |
| Machine-readable products with price, condition and warranty (Product / Offer schema) | Not published | Missing |
| Question-and-answer content an assistant can lift (FAQPage schema) | Not published | Missing |
AI crawler access in robots.txt | Open — no assistant is blocked | Good |
llms.txt summary file | Present, but auto-generated — page titles and meta text only, no engines, prices, specs or policies | Shallow |
| Consolidated answer content on engine families, build tiers, core charges or freight | None on the live site | Missing |
The good news hiding in that table: nothing is blocking the assistants. They are welcome to read the site — there is simply not enough specific, structured, quotable substance for them to pick this shop over a competitor that publishes engine families, tiers, prices, core policy and warranty terms in plain machine-readable form.
Baseline 4 — Social Reach
One real channel, doing real work, with nowhere to send people
| Channel | Baseline | Status |
|---|---|---|
| Facebook — Motorparts Plus, Kaufman TX | 3,500 followers · 36 page reviews · 92% recommend · posting within the last few days | Active |
| No business profile found | None | |
| YouTube | No channel found — despite a shop full of filmable engine builds | None |
| TikTok | No profile found | None |
| LinkedIn company page | No page found — nothing for fleet and commercial buyers | None |
| Yelp listing | Unclaimed · 1 review · 1.0 stars · last activity December 2019 | Neglected |
| Social traffic landing experience | Brochure pages with no product, no pricing and a pop-up — and link previews show no image | Weak |
A 3,500-follower audience built organically around engine work is a genuine asset, and it is the one thing here that is already working. The problem is the destination: every click currently lands on a page that cannot show an engine, quote a price, or capture a lead, and shares out of that page render with no image at all.
Baseline 5 — Reputation & Business Information
Strong reputation, unmanaged signals
| Signal | Baseline | Status |
|---|---|---|
| Google rating and review volume | 4.3 stars across 140 reviews | Strong |
| Owner responses to reviews | 0 replies across the 50 most recent reviews | None |
| Google Business Profile verification | Verified and active, with categories set | Good |
| Real customer reviews shown on the website | None — 140 reviews of social proof, zero of it on the site | Missing |
| Phone-number consistency across listings | 4 different numbers in circulation — three on the Google profile, a fourth on the chamber directory | Inconsistent |
Four phone numbers is a quiet, expensive problem. Search engines and AI assistants use name, address and phone agreement as a confidence signal; when a business publishes four numbers across four places, every one of them gets trusted a little less.
The Work — Built, Not Yet Launched
What the new site changes
The replacement is finished and sitting on a private, search-blocked preview while final pricing, warranty and freight details are confirmed with the shop. Here is what it addresses.
An engine catalog, not a brochure
Cummins engine families, build tiers, cylinder-head packages and overhaul kits published as browsable pages with real prices, including both with-core and without-core figures so first-time buyers understand the exchange model.
A guided build configurator
A dedicated Cummins builder with platform and tier selection, add-ons, a live estimate, plain-English explanations of each option, a help-me-choose flow, and side-by-side tier comparison for buyers who are not diesel experts.
A real lead path
Quote forms that carry the exact configuration into a tracked pipeline with email notification, replacing an every-page pop-up and a phone number as the only way to ask for a price.
Structured data throughout
Business, product, service, breadcrumb and FAQ markup so the shop, its engines, its prices and its policies are stated in a form search engines and AI assistants can quote directly.
Authentic social proof on-site
Real five-star Google reviews with real reviewer names and the actual 4.3 average from 140 reviews — no invented testimonials and no inflated rating.
The shop’s own photography
Hundreds of real shop and engine photos processed, optimized and served from the site itself — galleries of actual builds instead of stock imagery, with descriptive alt text throughout.
An AI assistant grounded in the shop
A knowledge base drawn from the shop’s own tiers, pricing, warranty, core and freight policies, so buyer questions get answered accurately at 11pm — and anything VIN-specific or safety-critical routes to a human.
Consistent business information
One canonical phone number, address and hours published on the site and aligned across the Google profile and directory listings, so the trust signals stop contradicting each other.
Methodology
How these numbers were captured — and how they get re-captured
- Website and technical audit. Every URL in the live sitemap was fetched and parsed for title, meta description, heading structure, structured-data blocks, image alt coverage, social tags and page weight.
- Fixed tracked query set. Ten commercial-intent searches were chosen to span local, metro, regional and national intent, then run once and recorded as top-10 presence or absence. The same ten strings get re-run verbatim.
- Answer-engine citation check. For each query we recorded whether the domain appeared among the sources an answer engine drew from, separating local-qualified queries from national commercial-intent ones.
- Answer-engine readiness check.
robots.txt,llms.txtand on-page structured data were inspected directly to see what a machine can actually access and quote. - Social and directory sweep. Five social platforms plus Yelp and the local chamber directory were checked for an owned presence, follower count, recency and business-information consistency.
- Verified profile data. Rating, review volume, category setup, listed phone numbers and owner reply rate were pulled from the business’s own verified Google Business Profile with owner-level access.
- Automated re-run. The whole procedure — the query list, the per-page audit script, the profile pulls and the roll-up arithmetic — is stored as a single reusable routine and scheduled to fire on , so the follow-up is executed the same way rather than reconstructed from memory.
- Archived evidence. Full-page screenshots of all live pages and the raw technical data were captured and archived on the capture date, so the “before” can still be inspected after the old site is gone.
