Rank tracking, keyword research and site audits through one API

The workflow

3 steps, one API key.

Run the steps in order, or call only the one you're missing. Every API links to its parameters, response fields and a live demo.

Step 1: Track rankings
Check organic positions on Google and Bing, local map rankings across a geo-grid, and whether Google's AI answers cite you. A monitor alerts you when a keyword drops.

Step 3: Audit your site

FAQ

SEO and rank tracking: questions

How deep does rank tracking go?

Up to position 100 on Bing and Google, billed per results page. Local rank grids check up to 49 points around a location, billed per point.

Where does backlink data come from?

From the Common Crawl web graph, a public crawl of billions of pages, refreshed quarterly. It covers domain-level links.

Can I track rankings automatically every day?

Yes. A serp_rank monitor checks a keyword on a schedule, records your domain's position in the top 50 Bing results, and alerts you by email or webhook when it falls below the position you set.

Why track Bing as well as Google?

Bing's index powers Microsoft Copilot and feeds ChatGPT search, so Bing rankings now shape AI visibility as well as classic search traffic.

How much does SEO and rank tracking with Gridlode cost?

Running the workflow on 1,000 items uses about 5,000 credits (Bing Search at 1 credits per call, Google Maps Rank Grid at 2 credits per point, Domain Authority at 1 credits per call and Website Crawler (Markdown for RAG) at 1 credits per page). That is $5.00 at list price and as little as $1.50 at enterprise volume. Every new account gets 1,000 free credits, failed requests are free and cached results cost half.
