Content Quality
How Cassian AI™ reads and evaluates your store's written content — Layer 2 of the Cassian Score™.
Content Quality
Content Quality is the second layer of your Cassian Score™, accounting for 25% of the total. Cassian AI™ reads the actual text on crawled pages of your store and evaluates it for quality, completeness, and clarity. To keep scans fast and consistent, each scan analyses new and changed pages — pages that haven't changed since the previous scan keep their earlier findings.
This isn't a keyword tool. Cassian isn't looking for missing keywords or search density metrics. It's reading your store the way a thoughtful visitor would, and flagging content that is likely to confuse, underwhelm, or lose customers.
What Cassian AI evaluates
Spelling and grammar
Cassian AI reads the visible text on new and changed crawled pages — product titles, product descriptions, collection page copy, page content, and blog posts — and flags spelling errors, grammatical mistakes, and punctuation issues.
A typo in a product title is more than a cosmetic problem. Customers notice. Studies consistently show that spelling errors reduce purchase intent, particularly on higher-priced products where trust matters most.
What gets checked:
- Product titles and descriptions
- Collection page headlines and body copy
- Standard content pages (About, FAQs, Shipping, Returns)
- Blog posts
What Cassian is careful about:
- Brand names, proper nouns, and deliberate stylistic choices are unlikely to be flagged as errors
- Technical product terminology is context-aware
- British vs American English spelling differences are read in context — Cassian AI evaluates spelling against the language the page is written in, so consistent regional spelling is unlikely to be flagged. If a deliberate variant is ever flagged in error, dismiss the issue
Where to fix: Issues → filter by Content → look for "Spelling" or "Grammar" issues. Each issue links directly to the affected page. Fix in your Shopify admin (Products → your product → Description, or Pages → your page).
Thin content
Product pages with very little text are flagged as thin content. The threshold is 50 words for product pages, and 30 words for other backend pages (About, FAQ, and similar content pages checked via a platform connector).
Why this matters: Thin product descriptions hurt both conversion rates (customers have less information to make a purchase decision) and search rankings (search engines treat very short pages as lower-quality content). Shopify stores that import catalogues from suppliers frequently inherit thin descriptions that were written for a trade catalogue, not a consumer storefront.
What counts as content: The word count covers all text in the page's main content area — including spec tables, bullet lists, and disclaimers. Separately, Cassian AI reads the page and judges whether the description has real substance: a page can clear the word count and still be flagged if the text doesn't actually describe the product.
The aim is a product description that could stand alone as a compelling, informative paragraph — not just a list of facts.
Where to fix: Issues → filter by Content → look for "Thin content" or "Missing description" issues. Expand each issue to see the affected product. A solid introductory paragraph before your spec table or bullet list clears the threshold comfortably and reads better for customers.
For large catalogues with many thin descriptions, consider prioritising your best-selling products first. A high-traffic product with a thin description is costing you more than a low-traffic product with the same issue.
Duplicate content
Cassian AI flags duplicate or near-duplicate content within a single page — the same paragraph repeated in multiple places, boilerplate copy pasted into several sections, or a description that restates itself. This is common when:
- Theme sections and product descriptions both render the same copy
- Supplier boilerplate is pasted into multiple content blocks on the same page
Why it matters: Repeated content on a page reads as careless to customers and dilutes the useful information search engines and AI systems can extract from it.
What Cassian does not currently do: compare descriptions across different pages. If ten products share the same supplier description, each page is evaluated on its own merits (a shared thin description will still be flagged as thin on each page).
Where to fix: Affected pages are listed in the Issues panel. Remove or rewrite the repeated blocks so each section of the page says something distinct.
Heading structure
Cassian validates the heading hierarchy on every crawled page. The rules:
- Every page should have exactly one H1 tag. In Shopify, most themes assign the product title or page title as H1 automatically. Don't add a second H1 in your description body.
- H2 and H3 should be used in logical order. Don't jump from H1 to H3, skipping H2.
- Avoid using headings purely for styling. If you want large text, use bold or increase font size via custom styling — don't use an H2 just because it looks big.
What Cassian flags:
- Missing H1 on a page (Medium severity)
- Multiple H1 tags on a single page (Low severity)
- Heading hierarchy that skips levels (H1 → H3) — the first skip found on each page is reported
Heading structure checks are deterministic technical checks, so they appear under the Technical filter on the Issues page rather than Content.
Where to fix: In Shopify's rich text editor, heading levels are available in the format dropdown. Review the affected pages listed in the Issues panel and check the heading structure in your description body.
Voice and readability
Cassian AI flags content whose tone is inconsistent with the rest of the store, and pages that present as unbroken walls of text. This check is intentionally conservative — Cassian won't flag technical terminology on a specialised product page.
This check is contextual: Cassian understands that a fishing tackle store will use different language than a children's clothing store.
What Cassian flags:
- Inconsistent brand voice or tone — copy that shifts register between pages or within a page
- Wall-of-text pages — long stretches of prose with no headings, paragraphs, or structure to break them up
Voice and readability flags are typically Medium or Low severity. They won't tank your score, but they're worth reviewing — clear, approachable copy converts better than technically accurate but impenetrable prose.
How Cassian AI reads your content
Cassian AI reads your pages the way a visitor would — it sees the rendered text content, not your source HTML. Each scan analyses pages that are new or have changed since the previous scan; unchanged pages carry their previous findings forward. This means:
- Content inside custom HTML that isn't rendered in the browser may not be evaluated
- Content loaded via JavaScript after page render may be partially or not captured (depending on your store's implementation)
- Popups, drawers, and modals that require user interaction to open are generally not evaluated
Most Shopify stores render their content server-side, so this isn't usually a concern. If your store uses a headless setup or heavy client-side rendering, some content may be less visible to Cassian AI.
Where to see Content Quality results
- Issues page → filter by "Content" category. All content issues listed by severity.
- Scans page → click any scan → Content Quality section shows your layer score and all issues found.
- Dashboard overview → the Content Quality card shows your current layer score.
Common questions
Does Cassian check blog posts? Yes. All crawled pages are analysed, including blog posts and blog index pages. Blog content is included in the spelling, grammar, and heading structure checks.
Why is my product description flagged as thin when it seems long enough? The 50-word threshold counts all text in the main content area, so a page flagged as thin genuinely has very little text on it. Separately, Cassian AI may flag a page that clears the word count if the text doesn't meaningfully describe the product — for example, a page that's mostly repeated boilerplate. Add a proper description paragraph that explains what the product is and who it's for.
Can I mark an issue as intentional? Yes — dismiss the issue from either the Issues page or directly from a scan detail page. A dismissed issue is hidden from your active issue lists. Dismissing an issue does not change your score — the score reflects what the scan found. Use dismissal to keep your issue list focused on things you actually intend to fix.
My store is set up in Australian English — will Cassian flag "colour" as a spelling error? Unlikely. Cassian AI reads spelling in the context of the page's language, so consistent regional spelling conventions are generally not flagged. If a deliberate variant is ever flagged in error, dismiss the issue.
I have thousands of products — do I need to fix all the thin content issues? Start with your highest-traffic products. The Issues page lists all affected products — sort by the severity level and prioritise the Critical and High items first. Low severity thin content issues (products with descriptions just below the threshold) can be addressed over time.
Cassian flagged duplicate content on a page but the repetition is intentional — what should I do? Duplicate content flags apply within a single page — the same copy appearing more than once on that page. If the repetition is deliberate (for example, a tagline repeated in a banner and the footer), dismiss the issue. If it's a theme section accidentally rendering the description twice, that's worth fixing — it reads as careless to customers.
