BotBridge · Bridge CDN

Bots don't run your JavaScript. Serve them a finished page.

BotBridge is Bridge CDN’s layer for crawlers and AI agents. Named bots get a prerendered HTML snapshot when the edge has one ready. Humans always get your origin.

Start on Bridge CDN How prerendering works

Prerendering, IndexNow and analytics are on every plan · AI SEO is Pro and up.

Prerender

Serve bots a finished page

Bot UAs get a server-rendered HTML snapshot from the edge. Humans get your origin, unmodified. If the UI hydrates in the browser, the crawler either sees a shell or a finished page.

Step 1

Classify the request

40 named crawlers decide the lane. You can add up to 50 more. Humans stay on origin; bots enter the prerender path.

Step 2

Cold path: origin now, warm behind

If no snapshot is ready, the edge serves origin immediately and warms the snapshot in the background. A bot is never held waiting on a live render.

Step 3

Warm path: finished snapshot

When a snapshot is ready, bots receive server-rendered HTML from the edge. Humans still get your origin, unmodified.

Finished HTML, not a shell

Bots get a server-rendered snapshot. Scripts are stripped by default. JSON-LD and AMP scripts stay.

A bot is never held waiting

IndexNow

Tell engines when a page changes

Edge change detection queues URLs to Bing, Yandex, Seznam, Naver, Yep, and api.indexnow.org. Bulk posts run on a short interval. Google is not in IndexNow. Keep sitemaps.

Six endpoints, one submission

Grouped per host and engine. Bulk POST on a short interval. Modes are fallback, balance, or all.

Key file on your hostname

The edge serves the verification key at your own hostname. Nothing to upload to origin.

Route rules, first match wins

Include and exclude globs pick eligible paths. No rules means the whole domain. One include makes the domain opt-in.

Submit changed URLs to IndexNow engines. Indexing stays each engine’s call.

IndexNow submission

Submit changed URLs. On every plan.

Fill missing, never overwrite

Injection runs in three tiers: your brand profile, deterministic derived values, then the generated record. Your tag always wins. Injected nodes use data-bb-seo="1". Missing og:image can be filled with a 1200×630 card.

Generated on our own hardware

A self-hosted model, not a third-party API. Output is checked before it is stored. Invalid records are never injected.

FAQ

Before you switch it on

Do bots always get the prerendered page?

No. The first bot to reach a path with no snapshot gets your origin, served immediately, while the snapshot is rendered in the background. The next crawler on that path gets the snapshot. A bot is never held waiting on a live render.

Does IndexNow submit to Google?

No. Google does not participate in IndexNow. IndexNow is an open standard supported by Bing, Yandex, Seznam, Naver, Yep, and the IndexNow aggregator, and BotBridge submits to all six. For Google, keep using sitemaps and on-page SEO.

Does AI SEO overwrite the tags I already wrote?

No. Injection is fill-missing only. Every injected node is marked with the attribute data-bb-seo="1", and any tag you authored yourself is kept. The generated one is added only when that tag is absent. Change your own meta description later and the generated one never replaces it.

Do human visitors see any of this?

No. Humans are routed to your origin, unchanged. Prerendering, generated markup, and snapshot caching apply to the bot path only, so generated tags land in the snapshot served to crawlers rather than in the response your visitors receive.

Does analytics need a script or a cookie?

Neither. Everything is computed at the edge from the request and response themselves, so there is no tag to install and no cookie is set. Visitor identity is a salted hash that rotates every day, uniques are counted and deduplicated daily, and country is resolved locally. Only pageviews, GET requests returning 2xx and text/html, enter the visitor pipeline.

What do bots receive?

A server-rendered HTML snapshot when the edge has one ready. Script tags are stripped by default. JSON-LD and AMP scripts stay. A page can declare its own HTTP status, and an origin 3xx is passed through as a real redirect.

What is on the free plan, and what needs Pro?

Prerendering, IndexNow, and analytics are on every plan, including Free. AI SEO enrichment is Pro and up, and it stays off on each domain until you switch it on. Volumes are tiered: IndexNow allows 500 URLs a day on Free and 10,000 on Pro, and analytics history runs 14 days on Free and 365 days on Pro.

Where do I sign up?

At bridge-cdn.com. BotBridge is the bot and AI-agent layer of Bridge CDN rather than a separate product, so you configure it from the Bridge, IndexNow, SEO, and Analytics tabs of the Bridge CDN dashboard, on the same account that manages your DNS, caching, and certificates.
