Summary
Summary This workflow enables the submission of business-critical URLs via the Google Indexing API and IndexNow. Why is this important for SEO? If your objective is visibility within AI-powered search and answer engines (such as Copilot, Perplexity, or OpenAI tools), the IndexNow integration is particularly relevant. IndexNow accelerates URL discovery for Bing and Yandex, which are key retrieval sources for several LLM-based platforms. In parallel, Google remains the dominant search engine, representing ~80% of global search traffic. Gemini is deeply integrated into Google’s ecosystem and, when grounding is enabled, can leverage Google Search as an external retrieval source. Ensuring fast and reliable indexation of critical URLs therefore remains a strategic foundation for both traditional SEO and AI-assisted search experiences. Description This workflow uses OnCrawl API endpoint to automatically discover your sitemaps.xml and submit their latest updates to both Google Indexing API and IndexNOW. It includes two variations: Index orphan pages detected in sitemap.xml and submit them to Google and IndexNow. Index newly released pages by identifying indexable canonical URLs added between a pre-release crawl and a post-release crawl. How it works This workflow works for Oncrawl users with API access enabled in their plan. if you are not an Oncrawl users, please refer to: https://n8n.io/workflows/8778-workflow-for-submitting-changed-sitemap-urls-using-google-indexing-api-and-bing-indexnow/ To get an API Key, just go in your User Account profile > tokens > + Add API access token: Description: any name Scope: select all checkboxes Click in Create token. Keep your API secret safe Discover & parse Sitemaps Create your first crawl by: Clicking in Create configuration > choose a template > Automate > Webhook. Webhook Node: In n8n, copy paste the Webhook callback URL into the Oncrawl Webhook section. At the end, Oncrawl sends a POST HTTP request to n8n containing: Workspace_ID, Project_ID, Crawl_ID. More details in Webhook Documentation: https://developer.oncrawl.com/#notification Discover_sitemaps endpoint: documentation: https://developer.oncrawl.com/. This endpoint checks the Sitemaps declared in your robots.txt file. You can filter the output to avoid duplicate sitemaps Config: It’s an initiation node that populate variables such as: Crawl_ID: Fetch from Webhook Node SITE_URL: Your site with the following format: https://your-site.com SITEMAP_URL: For subdomain sitemaps, you can duplicate this field. INDEXNOW_KEY: You can create it in the Bing Webmaster tools here https://www.bing.com/indexnow/getstarted INDEXNOW_KEY_URL: it's usually your domain and the INDEXNOW_KEY: wwww.example.com/ <INDEXNOW_KEY> Variables you can update depending on your specs: DAYS_BACK: 7 by default. BATCH_SIZE: 500 it's the default recommended by IndexNow USE_GOOGLE, USE_INDEXNOW: by default it's true which means the process will run for both Google and IndexNow Google Node Check Status Node (OAuth Setup): documentation: https://developers.google.com/webmaster-tools/v1/urlInspection.index/inspect Create credentials: https://console.cloud.google.com/apis/credentials Enable Google Search Console API Download the Client ID / Client Secret JSON Connect n8n using: Client ID Client Secret Scopes Google Search Console account All explanations are contained in these tutorials: https://www.youtube.com/watch?v=HT56wExnN5k | https://www.youtube.com/watch?v=FBGtpWMTppw Scopes reference: https://developers.google.com/identity/protocols/oauth2/scopes Google Index API: Create a service account here https://console.cloud.google.com/iam-admin/serviceaccounts Assign role: Owner Generate a JSON key (contains email + private key) For the two Google API nodes: Authentication: Predefined credential type Credential Type: Google Service Account API Credential configuration: Region: Your project region Service Account Email / Private Key: From the JSON key Enable “Set up for use in HTTP Request node” Scope: https://www.googleapis.com/auth/indexing ⚠️ Important: once you have created a "Service account email" you need to add a user with this email and permission "Owner" in your Google Search Console: https://search.google.com/search-console/users Others Nodes Gate: Google Is USE_GOOGLE = true from Cofig? Check status: Useful to get the coverageState and lastCrawlTime of a given URL given by Google Search Console Loop Over Items: Prevents rate-limiting Switch: Case: coverageState= “Submitted and indexed” -> Push to "isNew" node Case: coverageState= “Crawled - currently not indexed” -> Push to "URL Updated" node Is New: URLs from Sitemap with Last modification date AFTER the GoogleLast Crawl date If true, we submit URLs to Index API If false, no need to push that URL for indexation URL Updates doc: https://developers.google.com/search/apis/indexing-api/v3/using-api#gettinginfo Endpoint: https://indexing.googleapis.com/v3/urlNotifications:publish We call the Update URL request Wait: Generates a random delay between 0.30 and 1.50 seconds, rounded to 2 decimals ⚠️ Google alternative to batch index URLs consists in using Premium Service to by pass the URL inspection tool: https://fr.speedyindex.com/ IndexNow auto-submitting documentation: https://www.bing.com/indexnow/getstarted Gate: IndexNow: Is USE_INDEXNOW is true from Config? Split in Batches: split in batch of 500 URLs max to avoid rate Limiting issues Build IndexNow payload: description in the node name IndexNow Submit: Submit the URLs to indexNow VariationA: Index orphan pages API documentation: https://developer.oncrawl.com/#Data-API OQL definition: Get orphan pages for both sitemaps & logs Merge node: Merge Items that InnerJoin loc, url fields. This is useful to recover the lastmod from Orphan pages referenced into Sitemaps. This data can be shared into Google Node afterward. Input1 should be: "Assign mandatory sitemap fields" Node Next nodes change "Set Node" name in the script variables VariationB: Index newly added pages between a Crawl 1 & a Crawl2 API documentation: https://developer.oncrawl.com/#Data-API OQL definition: Returns indexable canonical pages added in Crawl 2 Merge node: Merge Items that match between loc, url fields. This is useful to recover the lastmod data for Google Node Input1 should be: "Assign mandatory sitemap fields" Node Next nodes change "Set Node" name in the script variables.
