IndexNow in 2026: The Protocol That Makes Press Releases Instantly Discoverable

TL;DR

IndexNow has evolved from a promising protocol to essential infrastructure in 2026. With AI search engines increasingly relying on fresh content, instant indexing is no longer optional—it's competitive necessity.

2026 State of IndexNow:
- 5+ billion URLs submitted daily (up from 3.5B in 2024)
- 22% of clicked URLs in Bing results come from IndexNow
- 80+ million websites actively using the protocol
- Supported by: Bing, Yandex, Naver, Seznam, Yep
- Still NOT supported by: Google (but AI search changes the equation)

Pressonify uses IndexNow to ensure your press releases appear in search results within minutes—critical for AI citation in 2026.

The Problem: Traditional Indexing Is Slow

When you publish a press release on most platforms, here's what happens:

1. Your press release goes live on the web
2. You wait... and wait... for search engine crawlers to find it
3. Days or weeks later, it finally appears in search results
4. By then, your "news" is no longer new

The traditional model is broken for time-sensitive content. Search engines operate on a "pull" model—they crawl websites on their own schedule, looking for changes. For a new website or infrequently updated page, this can take weeks.

For press releases announcing product launches, funding rounds, or breaking company news, waiting weeks for indexing defeats the entire purpose.

The Solution: IndexNow's Push Model

IndexNow flips the script. Instead of waiting for search engines to discover your content, you push the update directly to them.

How IndexNow Works

Traditional Model:
Publisher → Publishes content → Waits → Crawler discovers → Indexed (days/weeks)

IndexNow Model:
Publisher → Publishes content → Pings IndexNow → Indexed (minutes)

Technical flow:

1. Publisher generates a unique API key
2. Publisher hosts verification file at their domain (e.g., yourdomain.com/key.txt)
3. When content is published, publisher sends POST request to IndexNow API
4. Participating search engines receive the notification
5. Content is indexed almost immediately

The brilliant part: When you submit to one participating search engine, they automatically share with ALL other participating search engines. One ping, multiple indexes.

Which Search Engines Support IndexNow?

As of December 2025, these search engines officially support IndexNow:

The Google Question

Google does NOT support IndexNow.

This is the most common question we receive, so let's address it directly:

• Google announced they were "testing the potential benefits of the protocol" in 2021
• As of December 2025—over three years later—Google still hasn't adopted it
• Google maintains its own massive crawling infrastructure
• Google offers a limited Indexing API (only for job postings and live streaming content)

What this means for you: IndexNow accelerates your visibility on Bing, Yandex, and other search engines. For Google, you still need:
- XML sitemaps
- Google Search Console
- Quality backlinks
- Standard SEO practices

At Pressonify, we implement both approaches—IndexNow for instant Bing indexing, plus comprehensive SEO for Google visibility.

The Numbers: IndexNow Adoption in 2025

IndexNow has achieved significant adoption since its 2021 launch:

• CDNs: Cloudflare, Akamai
• E-commerce: eBay, Amazon
• Tech: LinkedIn, MSN, GitHub

Why IndexNow Matters for Press Releases

Press releases are inherently time-sensitive. A funding announcement, product launch, or partnership reveal has a limited window of relevance.

The Traditional Press Release Timeline

Day 0: Press release published
Day 1-3: Journalists may cover the story
Day 7-14: Search engines finally index the release
Day 14+: The "news" is stale

With IndexNow

Minute 0: Press release published
Minute 1: IndexNow ping sent
Minute 5-30: Indexed on Bing, Yandex, Naver
Same day: Discoverable in search results

The difference: Your press release is discoverable in AI search engines and traditional search within minutes, not weeks.

How Pressonify Uses IndexNow

Every press release published through Pressonify automatically triggers IndexNow submission:

Our Implementation

1. Automatic key management: We handle API key generation and verification
2. Instant ping on publish: The moment your PR goes live, IndexNow is notified
3. Multi-URL submission: We submit the PR page, your company website, and related pages
4. Verification logging: Track when your content was submitted and confirmed

What We Submit

For each press release, we submit:
- The published PR URL (pressonify.ai/news/your-release)
- Updated sitemap references
- RSS feed updates
- AI Discovery Protocol endpoints

Combined with ADP 2.1

IndexNow handles search engine discovery. Our AI Discovery Protocol (ADP) handles AI search engine discovery:

Together, they ensure your press release is discoverable across both traditional and AI search ecosystems.

Technical Implementation

For developers interested in implementing IndexNow, here's how it works:

1. Generate an API Key

Create a random string (e.g., a1b2c3d4e5f6g7h8i9j0)

2. Host Verification File

Create a text file at your domain root:

https://yourdomain.com/a1b2c3d4e5f6g7h8i9j0.txt

The file should contain only the key value in UTF-8 encoding.

3. Submit URLs

Single URL:

GET https://api.indexnow.org/indexnow?url=https://yourdomain.com/new-page&key=a1b2c3d4e5f6g7h8i9j0

Batch submission (up to 10,000 URLs):

POST https://api.indexnow.org/indexnow
{
  "host": "yourdomain.com",
  "key": "a1b2c3d4e5f6g7h8i9j0",
  "keyLocation": "https://yourdomain.com/a1b2c3d4e5f6g7h8i9j0.txt",
  "urlList": [
    "https://yourdomain.com/page1",
    "https://yourdomain.com/page2",
    "https://yourdomain.com/page3"
  ]
}

4. Response Codes

Note: A 200 response means the URL was received, not that it will definitely be indexed. Search engines still apply their own quality filters.

Frequently Asked Questions

What is IndexNow?

IndexNow is an open protocol that allows website owners to instantly notify search engines about content changes. Instead of waiting for crawlers to discover new content (which can take days or weeks), publishers can push updates directly to participating search engines.

Does Google support IndexNow?

No. As of December 2025, Google has not adopted IndexNow despite testing it since 2021. Google maintains its own crawling infrastructure and has a separate Google Indexing API limited to job postings and live streaming content. For Google indexing, traditional methods like XML sitemaps and Google Search Console remain necessary.

Which search engines support IndexNow?

Microsoft Bing, Yandex, Naver (South Korea), Seznam.cz (Czech Republic), and Yep all support IndexNow. When you submit URLs to one participating search engine, they automatically share with all others.

How fast does IndexNow work?

IndexNow provides near-instant notification to search engines. While indexing itself depends on search engine processing, content typically appears in search results within minutes rather than days or weeks.

Is IndexNow free to use?

Yes, IndexNow is completely free and open-source. There are no fees to submit URLs, and the protocol is available to any website owner.

Conclusion
