How is alt text generated — once per image or every page view?
Once per image. On the first page load where an image appears without alt text, the snippet triggers generation. The result is cached and returned instantly on every subsequent visit without repeat API calls. New images go through the same cycle automatically.
What happens to images that already have alt text?
The snippet only processes images that are missing alt text. Existing alt text is never overwritten or modified.
Do I need a developer to install Web Snippet?
For the direct HTML method, you need someone who can edit your site's <head>. If you use Google Tag Manager, no developer access is required — you can deploy it yourself.
Can I use Web Snippet without a plugin on WordPress or Shopify?
Yes. The Web Snippet works on any platform, including WordPress and Shopify. Paste it before the </head> tag or add it via Google Tag Manager. If you want alt text written permanently to your CMS database, the native plugins are a better fit, but the snippet works for any site where you want coverage without a plugin.
Will the Web Snippet slow down my website?
No. The script loads asynchronously after your page renders, it adds zero blocking time and has no effect on your Core Web Vitals score. Once alt text is cached in our Cloudflare CDN, it loads in milliseconds on every subsequent visit.
Does Web Snippet work on images loaded dynamically like CMS content or JavaScript-injected images?
Yes. The snippet scans the rendered page, not the source HTML. That means it catches images loaded from CMS collection lists, injected by JavaScript after page load, or served by third-party embeds — all the images a plugin would miss.
Does Web Snippet work with single-page apps?
Yes. The script runs after the page loads and handles dynamically rendered images, including those injected by JavaScript frameworks after the initial render.
What happens to existing alt text if I cancel my subscription?
Generation stops for new images immediately. Alt text that's already been generated stays live on your site for 30 days served from CDN as normal. After that, the files are removed from CDN and stop appearing.
Your data isn't deleted. Everything stays in your account. When you reactivate, all previously generated alt text returns to CDN automatically with no reprocessing and no credits used — and your site picks up exactly where it left off.
