You're renting SEO fixes. Not owning them.
Every major SEO automation tool deploys changes via JavaScript overlay. Fast to install. But the moment you cancel — or they go down — your optimizations vanish. Here's what that means for your site.
The JavaScript Overlay Problem
JavaScript injection sits on top of your CMS. It doesn't touch it natively. A script runs in the browser, modifies the DOM, injects meta tags — and from the user's perspective, the page looks updated. But nothing is written to your actual database. Your WordPress posts, your Contentful entries, your theme files — unchanged.
If you uninstall the pixel before saving your changes, here's what could vanish: all technical fixes, content optimizations, custom HTML edits, schema markup.

Changes made via JavaScript overlay revert when the script is removed or the subscription lapses.
— Alli AI, support documentation
This isn't a bug. It's the architecture. JavaScript injection was designed for speed of deployment — not permanence of change. You're not fixing your site. You're renting a layer on top of it.
What Native Writes Actually Mean
REST API
Writes directly to WordPress, Shopify, Contentful via Application Password or API key. No plugin. No pixel.
SSH
Writes theme files, functions.php, templates directly on the server. Path-restricted, no open shell.
Git / GitHub
Opens a PR with every change. CI runs. Merges to production. Full audit trail.
Cancel your subscription. Every fix stays. Because we never injected code — we fixed your site.
How the architectures compare
| JS Injection (Alli AI, OTTO) | Native Writes (effectly.ai) | |
|---|---|---|
| Changes survive cancellation | ||
| Visible in your CMS | ||
| Audit log you can export | ||
| Works without their servers running | ||
| Enterprise IT approval | ||
| One-click rollback | ||
| Changes compound over time |
The Setup Trade-off
Competitors sell JS injection as a benefit: "No developer needed — just paste our code."
We'll be honest: connecting to your CMS natively takes 20 minutes. You paste one Application Password. You add one SSH key. You create one GitHub token.
That's the trade-off. Twenty minutes of setup. Permanent ownership of every fix that follows.

Agencies
Managing 10 client sites on JS injection means months of work vanishes if you switch tools. Native writes mean every client's SEO is theirs — permanently.
In-house teams
You're building long-term SEO infrastructure. Native writes compound. Overlays evaporate.
Enterprise
Immutable audit logs. Exportable history. Changes visible in your own CMS. That's what compliance teams ask for.
Cancel anytime. Keep everything.
No pixel to remove. No changes to manually save. Just permanent, native SEO execution — nightly.
