Squirrly is a good WordPress SEO plugin. It has been around for years, it handles classic Google SEO well, and recently it added AI-search features like an llms.txt generator. If you use it and like it, you do not have to remove it - more on that at the end.
EZY.ai is the AEO platform built for one job Squirrly was not: making your business the answer when someone asks ChatGPT, Claude, Perplexity or Gemini for a recommendation. We ran a 698-page technical audit across four business websites where both plugins were installed, fetched every page live, and validated every piece of structured data on every page. This comparison is built from what that audit actually found.
1. Schema - what we tell the AI about your business
In plain English
Schema is a label sheet attached to your website that only machines read. It tells Google and AI assistants what your business is, what you sell, when you are open. If the labels are wrong or vague, the AI guesses - and it usually guesses your competitor.
The depth difference, using real examples from the audit (verticals only: plumbing, local trades, agency):
- A plumbing company running EZY.ai carried: Plumber (the exact business type, not just "Organization"), 15 separate Service entities - one for each service they actually sell - and an FAQPage. All validated clean.
- A local-business site running EZY.ai carried: LocalBusiness, 6 Service entities, plus Product, Brand and Offer - so an AI knows not just who they are but what they sell and on what terms. All validated clean.
If you are an SEO agency, EZY.ai does not label you "Organization" and move on. It says exactly what you are, then itemises every service as its own entity, because "who does emergency boiler repair near me" is answered from the Service entity, not the company name.
What the audit found in Squirrly's output on the same portfolio
- Opening hours used an en dash in the weekday range instead of a hyphen. Looks identical to a human. To a machine it is not the required format, so parsers reject the business's opening hours entirely.
- Weekend opening hours stamped validFrom / validThrough 0001-01-01 - a placeholder date that declares the hours valid only during the year 1 AD.
- 37 blog posts typed as NewsArticle. Google restricts NewsArticle to news publishers; business blog posts should be BlogPosting or Article. Half the site's content was dressed as a newspaper, a live rich-result eligibility risk.
In plain English
One wrong dash, one placeholder date, one wrong label - and a machine quietly ignores your opening hours and doubts half your content. Nobody sees it happen. That is why we spent months on schema before we spent a day on anything else.
2. The sitemap - the menu you hand the crawlers
In plain English
A sitemap is the menu of your website you hand to Google and the AI crawlers. If a page is not on the menu, crawlers can miss it - and the pages most often missing are the exact ones that win you customers. See also sitemaps.
In the audit, EZY.ai's sitemap contained every URL Squirrly's did, plus 26 more. The 26 website pages Squirrly omitted were: every individual service page (termites, bed bugs, cockroaches), every wildlife page, both category archives. Those service pages are the pages that earn the rankings and the AI citations. They were absent from the menu Squirrly publishes.
All 697 sitemap URLs across four domains were fetched live in the audit: every one returned 200. No 404s, no redirects, no blanks.
3. llms.txt - the file written for AI, not Google
In plain English
llms.txt is a new standard: a file on your site written specifically for AI assistants - here is who we are, here is what matters, here is how to cite us. Think of it as the press kit you leave at the door for ChatGPT.
Squirrly added an llms.txt generator - credit where due, most SEO plugins still have none.
The difference is what the file contains. EZY.ai's llms.txt is engineered: citation-format instructions, page prioritisation for different question types, a companion llms-full.txt carrying the complete detail, and both kept current automatically as your site changes. Ours run to tens of kilobytes of structured guidance, not a ten-line list of links.
For what "engineered" means in practice, Gemini Pro scored an EZY.ai llms.txt against a site's existing file, 95 to 35, quoted unedited in content quality results. The full argument for why the file has to be engineered rather than exported is in why your llms.txt needs engineering.
What Squirrly's own llms.txt contains
We checked the file live on Squirrly's own website, squirrly.co/llms.txt, on 31 August 2026. Here it is in full:
User-Agent: * Allow: / Disallow: /wp-admin/ Disallow: /wp-login.php Disallow: /xmlrpc.php Disallow: /wp-json/ Disallow: /?author= Training: disallowed Summarization: allowed Embedding: allowed Require-Attribution: true
Two factual observations. First, that is robots.txt syntax under an llms.txt filename - the standard is markdown content describing the site: who you are, what you offer, what to cite. Second, the file contains no information about Squirrly at all. There is nothing in it an answer engine could quote, cite, or recommend from. For comparison, EZY.ai's own llms.txt runs to tens of kilobytes of structured facts, citation guidance and page prioritisation, with a full-detail companion file alongside it.
4. Content - a year of engineering, visible in the output
In plain English
Anyone can bolt an AI onto WordPress and generate articles. The hard part - the part that took us a year - is making articles an AI engine trusts enough to cite: every claim traceable, structure machines can lift, and no two sites sounding alike.
- A verification pipeline that blocks any claim it cannot trace to your own pages or data. If it cannot source it, it does not publish it.
- Multiple LLMs in sequence - one drafts, others check facts, tone and originality, with NLP passes for structure and entity coverage.
- Dynamic lead-capture forms inside articles, whose promises are checked against your actual services before they render.
- Internal links, FAQ blocks with schema, and comparison tables built in - the formats AI answers lift from.
- Register matched to your vertical: consumer-warm for travel, professional for law, technical for SaaS.
Squirrly's assistant helps you write and optimise for Google keywords. It is classic SEO tooling - good at its job, aimed at a different target. See why EZY's Content Engine is not another AI blog generator.
5. Receipts - who actually visited
In plain English
Across 100+ connected sites, EZY.ai tracks real AI-crawler traffic and ties it to what was published. Then it tracks what the engines actually answer. Every week it runs your real customer prompts through the AI engines and records whether you were cited and where - a historical trend line, not a one-off snapshot. Your share of voice is tracked the same way, week over week.
Competitors get the same treatment: add any competitor and EZY.ai runs searches against them every week, so you see exactly where they appear against you in AI answers - and when a fix you published overtakes them. That is prompt and citation tracking, also covered on competitor analysis.
Squirrly's reporting is built around Google rankings, which is its job. None of this layer - crawler fetches, weekly citation checks, AI share of voice, competitor visibility in AI answers - has an equivalent there.
6. You do not have to choose
The audit's recommendation was not "remove Squirrly." It was one owner per output type: EZY.ai owns the AI layer - sitemap, robots.txt, llms.txt, schema (migrated page by page so coverage only ever increases) - while meta descriptions were already flowing cleanly through Squirrly's own pipeline, one tag per page, no conflict. Keep Squirrly for the classic SEO workflow you know. Give the AI layer to the tool built for it. Since v2.3.2 every EZY.ai output has a one-click toggle, so ownership is a setting, not a fight. If you are on WordPress, start with the AEO tool for WordPress.

Frequently asked questions
Can I run EZY and Squirrly together?
Yes. Give each output one owner: EZY takes the AI layer (schema, sitemap, llms.txt, robots.txt), Squirrly keeps whatever classic SEO workflow you like. EZY has per-feature toggles.
Does Squirrly's llms.txt do the same thing as EZY's?
Both can create the file. EZY's carries citation instructions, page prioritisation and a full-detail companion file, updated automatically. Squirrly.co's own llms.txt, checked live on 31 August 2026, is robots.txt syntax with no citeable facts about the business.
Why did an audit find schema errors if a plugin was installed?
Because errors hide in machine-only formats - a wrong dash in opening hours looks fine to a human and invalid to a parser. Validation, not installation, is what proves schema works.
What did the 698-page audit cover?
Four WordPress sites where both plugins were installed. Every page was fetched live and every piece of structured data was validated. The sites were in pest control, plumbing, HVAC and agency verticals. No client names or domains are published.
