You ran the free AEO check. You got a letter grade. Maybe it was a B and you felt decent about it. Maybe it was a D and you are not sure what that means for your business. Either way, you are looking at a single letter and wondering what comes next.

This article breaks down exactly what each grade means in real terms. Not theory. Not vague suggestions. We will walk through the scoring system, explain what each letter tells you about your site, and give you the specific fixes that move the needle fastest.

AEO (Answer Engine Optimization) is how your brand gets cited by AI search engines like ChatGPT, Perplexity, and Google AI Overviews. Your AEO score measures how ready your site is to be picked up by those systems. If you want background on what AEO is and why it matters, start with our primer. And if you have not already, check if your business shows up in ChatGPT to see the real-world impact of your score.

How the score works

Your AEO score runs from 0 to 100. It is calculated across four weighted categories, each measuring a different dimension of AI visibility readiness.

Schema Coverage -- 30 Points

Which structured data types are present on your page. Organization schema, WebSite schema, BreadcrumbList, FAQPage, Article -- each one tells AI models something specific about your content. Missing schema means the model has to guess. Models do not like guessing. They cite sources that make extraction easy.

Technical Signals -- 40 Points

This is the largest category because it covers the basics that most sites still get wrong. Title tags, meta descriptions, canonical URLs, Open Graph tags, and heading structure. These are the signals AI crawlers read first when deciding whether your page is worth indexing. A missing canonical tag alone can split your authority across duplicate URLs, making it harder for any AI engine to identify your authoritative page.

Authority Signals -- 20 Points

External links pointing to your content, entity mentions across the web, and cross-platform presence. AI models weigh third-party validation heavily. If other trusted sources reference you, the model treats your content as more citable. This is the hardest category to improve quickly, but it compounds over time.

Content Signals -- 10 Points

Word count, heading hierarchy, and content depth. Thin pages with 200 words and no subheadings score low here. This category carries the smallest weight because content alone does not drive AI citations -- but without adequate content, the other signals have nothing to point to.

What each grade means

The letter grade maps directly to your numeric score. Here is what each one tells you about where your site stands today and what to do about it.

Grade A -- Score 80 to 100

You are ahead of the field. Your schema is deployed, your entity is registered across platforms, and your content is structured for extraction. AI engines can identify your brand, parse your content, and cite you with confidence.

The risk at this level is complacency. AEO is going mainstream. Competitors who were ignoring structured data six months ago are now deploying it. Your lead is real but not permanent.

Action: Monitor your score weekly. Expand schema coverage to new page types as you publish. Track your citation frequency across ChatGPT, Perplexity, and Google AI Overviews. Protect the advantage you built.

Grade B -- Score 60 to 79

The foundation exists but gaps remain. You probably have Organization schema and decent technical signals, but something is missing. The most common issues at this level: no FAQ schema on pages that answer questions, no BreadcrumbList on subpages, and thin entity recognition because your sameAs links are incomplete or absent.

A B grade means AI engines can find you, but they are not getting the full picture. You are leaving citations on the table.

Action: Fill the specific gaps. This is exactly where the $500 audit pays for itself -- it identifies every missing signal and prioritizes them by impact. The difference between a B and an A is usually three to five targeted fixes, not a full rebuild.

Grade C -- Score 40 to 59

This is the most common grade we see. You have title tags and meta descriptions. Your site loads. The basics are in place. But there is no structured data. No schema telling AI models who you are, what your content covers, or how your pages relate to each other.

AI engines can read your site, but they cannot extract structured information from it. They are working with raw HTML instead of clean, labeled data. That means they will cite a competitor who made extraction easy before they cite you.

Action: Schema deployment is the single highest-leverage move you can make. Adding Organization, WebSite, and BreadcrumbList schema to your site can move you from a C to a B in a single deployment. Read our schema markup guide for the specifics.

Grade D -- Score 0 to 39

Major gaps across multiple categories. A D grade often means no schema at all, missing canonical tags, no Open Graph tags, and thin content. The technical foundation that AI engines need to index and cite your site is not there.

Sites at this level do not get cited by AI engines. Full stop. The models cannot confidently identify what the site is, who runs it, or whether the content is authoritative. You are invisible to the fastest-growing discovery channel on the internet.

Action: You need a full technical and content rebuild for AI visibility. This is not a quick-fix situation. Start with the $500 audit to get a complete gap analysis and a 90-day roadmap. Trying to patch individual issues at this level wastes time because the problems compound.

Grade F -- Scan Failed

The scanner could not complete its analysis. This usually means your site returned errors, blocked the crawler, or timed out. Common causes: the site is down, robots.txt is blocking access, the server returned a 500 error, or a firewall blocked the scan.

Action: Fix the technical issues preventing the scan from running. Check that your site is live, your robots.txt is not blocking crawlers, and your server responds within a reasonable time. Then run the free check again.

Three fixes that move every grade

Regardless of where you scored, these three changes deliver the highest impact per hour of effort. They apply at every level from D to A.

1. Deploy Organization Schema

This is the single most important piece of structured data for AEO. Organization schema tells AI models who you are -- your company name, logo, contact information, social profiles, and founding details. Without it, the model has to piece together your identity from scattered signals across the web. With it, the model knows exactly what entity it is looking at. Deploy this site-wide on every page.

2. Add FAQ Schema to Key Pages

If you have pages that answer common questions about your industry, product, or service, wrap those Q&A pairs in FAQPage schema. This is the format AI models use to generate direct answers. When a user asks ChatGPT or Perplexity a question and your FAQ schema contains a clear, structured answer, you become the path of least resistance for citation. The model does not have to extract and interpret -- you already gave it the answer in a ready-made format.

3. Fix Canonical Tags

Duplicate content confuses AI models the same way it confuses traditional search engines, but the consequences are worse. When a model encounters multiple URLs with the same content and no canonical tag pointing to the authoritative version, it may cite none of them. Or it may cite the wrong one. Canonical tags resolve this by telling every AI crawler which URL is the real one. Check every page on your site. If the canonical tag is missing or points to the wrong URL, fix it.

Why you need to check again next week

AI indexes refresh constantly. Google recrawls and updates its AI Overviews. ChatGPT and Perplexity pull from updated data sources. Your competitors are deploying schema, publishing content, and building authority signals every week.

A score from last month is already stale. The site that scored a C three weeks ago may have deployed schema and jumped to a B. The site that scored an A may have introduced a technical regression that dropped it to a C. AEO is not a one-time optimization. It is an ongoing practice.

That is why the free check exists with no signup and no email gate. Run it weekly. Track your score over time. Watch for regressions after site updates. The brands that monitor consistently are the ones that hold their positions in AI answers.

Get the full picture

The free check gives you a grade and a high-level breakdown. It is designed to show you where you stand in 30 seconds. But it does not map every gap, prioritize fixes by impact, or build a deployment timeline.

The $500 audit does. You get a complete analysis of every AEO signal on your site, a prioritized list of fixes ranked by how much they move your score, and a 90-day roadmap for compound AI visibility. One deliverable. No retainer. No ongoing commitment unless you want one.

Start with the free check. If the grade tells you what you need to know, great. If you want the full roadmap, the audit is there.
