A browser snippet changes a page after it loads. Preferium changes the HTML before it is sent, without adding a script to the client site. OTTO and Alli AI also document server-side options; compare each delivery mode before choosing one for your clients.
Compare the HTML a crawler receives without running a browser script.

Script-dependentA crawler that does not run the script misses those changes.

Our deliveryThe crawler receives the supported changes.
No page script. No CMS plugin. The original CMS stays unchanged.
Server-rendered pages receive the same HTML for people and crawlers. JavaScript-built pages require browser rendering.

Export deployed changes. The client’s CMS stays unchanged.
Edge delivery stops with the service; the client’s CMS stays unchanged. Export every deployed change as CSV at any time. Qualifying clients can use frozen delivery to keep published pages live, unchanged and unbilled.
Core page elements are checked after deployment. Regressions trigger rollback.
After deployment, a real browser checks the live title, meta description, H1 and structured data. If those checks detect a regression, the change is rolled back and you are alerted. Other changes remain reversible with one click.
Track mentions and citations across six answer surfaces.
Four assistants with prompt tracking, six answer surfaces in total: ChatGPT, Claude, Perplexity and Gemini, plus Google AI Mode and AI Overviews. Results come from real answers with web search. Mention rates include confidence ranges.
See the HTML returned to a named AI crawler.
Crawler View shows the title, meta description, H1 and structured data returned when a client’s live page is requested as a named AI crawler.
Connect the site without installing a CMS plugin.
Connect with one CNAME record to ssl.preferium.com. The certificate is issued automatically and the client’s server is checked before go-live. Preferium remains visible in public DNS and required legal disclosures.
Choose the approval level and control visible rewrites per site.
Choose Full autopilot, Invisible-only or Review everything for each client site, and control visible rewrites separately. Element optimization is charged only for elements changed; crawling, audits and measurement can use credits separately.
Fair is fair
Snippet-based tools are quick to install and can suit clients who cannot change DNS. Some support closed builders such as Wix and Squarespace, which Preferium does not.
A browser-side change reaches a crawler only if it runs the script or receives a rendered version. Check the HTML that the crawler actually receives.
