Tell Bing about every new page the moment it goes live

IndexNow page submission in Proofsource is for teams that publish fixes and new pages to win AI answers. Each new page Proofsource publishes for you is announced to Bing and other search engines that support IndexNow. Your key is created on the first publish, or you can reuse a key your site already serves, and Proofsource checks the key file before it relies on it.

IndexNow sits beside your site builder in the list of places Proofsource acts for you.

IndexNow key and page submission. Proofsource sets up or reuses your IndexNow key, verifies the key file on your site, and announces new pages to Bing and other search engines through the protocol.

IndexNow, explained

IndexNow is an open protocol that lets a website tell search engines a URL is new or changed, instead of waiting for a crawler to find it. The site hosts a small key file at its root to prove ownership, then sends the changed URLs to an IndexNow endpoint. Bing and several other search engines take part, and one notice is shared among them.

Speed matters for AI visibility. When you publish a page to answer a buyer question, it cannot help until search engines know it exists, and several AI answers draw on search results, Microsoft Copilot on Bing's among them. Telling the engines straight away removes one wait from the loop of publish, get read, get quoted.

Proofsource does this for you whenever it publishes a page for your brand. It creates your IndexNow key on the first publish, or uses the key your site already serves once it has fetched and checked the file, then announces each new page and records the answer the endpoint gave. The limit is plain: a notice accepted by IndexNow says the engines were told, not that any AI engine read or cited the page.

How it works

Every new page Proofsource publishes for you is announced to Bing and other search engines through IndexNow, with your key set up and verified.

  1. A key is set up

    On your first publish Proofsource makes an IndexNow key. If your site already serves one, enter it instead.

  2. The key file is checked

    Proofsource fetches the key file from your site's root and only marks the key verified when the file holds it.

  3. A page is published

    When Proofsource publishes a fix to your site, such as a new comparison or answer page, the new URL is ready to announce.

  4. Search engines are told

    The new page is announced to Bing and other IndexNow search engines, and the result is logged.

  5. Results are measured where it counts

    Whether the page changes AI answers is measured separately, by asking the engines your buyer questions again.

Questions about IndexNow page submission

What is IndexNow?

An open protocol that lets a website tell participating search engines, including Bing, that a page is new or has changed, so they do not have to wait to discover it.

When does Proofsource submit pages?

Whenever it publishes a new page to your site for you, such as an approved fix through your connected site builder.

Do I need to set anything up?

A key file has to be at your site's root. Proofsource creates your key on the first publish, and if your site already serves an IndexNow key you can enter it and Proofsource checks the file before using it.

Does IndexNow get my page into ChatGPT or Perplexity?

Not directly. IndexNow tells search engines about the page. Whether any AI answer then quotes it is a separate question, which Proofsource answers by asking your buyer questions on every engine your plan covers again.

Which search engines receive the notice?

Bing and the other search engines that take part in IndexNow share notices with each other.

What if my key file is missing?

Proofsource tells you the file is not there yet and where to put it. Until it is there, Bing may refuse the notice.

How is this different from Profound's content submission?

Profound offers direct submission to AI crawlers within its Agent Analytics. Proofsource announces pages through the open IndexNow protocol as part of publishing, then measures any change in AI answers separately.
