Answers to the most common questions about AltSnap’s automated QA scans, alt-text generation, and AI-powered site reports.
Lighthouse is great for one-off snapshots. AltSnap is built for ongoing QA. It runs lightweight scans through a snippet on every page load, tracks issues over time, and generates client-ready reports that cover accessibility, SEO, AEO, content structure, and technical health in one place.
The snippet lets AltSnap “see” your site the same way a user or screen reader does. It detects pages, reads headings and copy, identifies accessibility/SEO/AEO issues, and confirms when fixes are actually deployed — all without template rewrites or CMS plugins.
AEO (Answer Engine Optimization) is about how well your content surfaces in tools like ChatGPT, Copilot, Gemini, and Perplexity. Content-heavy sites (blogs, docs, knowledge bases) benefit the most. For simple brochure sites, low AEO scores are not critical, but accessibility and SEO still matter.
No. Developer-provided alt text always wins. AltSnap only fills in the gaps when alt attributes are missing, and you can edit or override anything in the cache. Think of it as a safety net, not a replacement for human judgment.
No. The snippet is lightweight, non-blocking, and behaves more like an analytics script than a heavy widget. Alt text and scores are served from cache, and scans are throttled on the backend to protect performance.
Each plan includes a monthly pool of image analyses, served alt-texts, and AI QA reports. If you go over, we charge simple, predictable overages instead of throttling your scans, so sites stay covered while you decide whether to upgrade.
