Quick Start — 3 Lines of Code
Call the SEO audit API from any language. Here's a minimal example in JavaScript — no API key required:
const response = await fetch(
"https://www.auditme.dev/api/v1/audit?url=https://example.com"
);
const data = await response.json();
console.log(data.score.percentage); // 85
console.log(data.page.title); // "Example Domain"
console.log(data.recommendations); // [{ type: "warning", impact: "medium", ... }]
console.log(data.ai_insights); // "Add alt text to improve..."The response includes the SEO score (0–100), page-level metrics, prioritized recommendations, and AI-generated insights.
Why Your App Needs an SEO Audit API
Search engine optimization is no longer a manual, one-person job. Modern websites generate hundreds or thousands of pages, and keeping every one optimized for search visibility requires automation. That is exactly what an SEO audit API provides — a programmatic way to evaluate any page on your site and get back structured, actionable data without opening a browser.
For agencies and SaaS platforms, an SEO audit API enables entirely new product possibilities. You can build automated SEO monitoring dashboards, generate client reports on a schedule, or embed SEO scoring directly into a CMS workflow so content teams get instant feedback before publishing. Instead of paying for individual tool seats, every integration calls the same open, free endpoint.
Developers building website builders, e-commerce platforms, or marketing automation tools benefit just as much. Embedding an SEO check API into your onboarding flow means every new user gets a site audit the moment they connect their domain. That first audit often reveals quick wins — a missing meta description, a bloated image, or an invalid schema — that demonstrate immediate value and reduce churn.
From a technical standpoint, the API covers the key dimensions of on-page SEO. Meta tag analysis catches missing titles, descriptions, and Open Graph gaps. Page metrics report load time, word count, and status code. Schema detection verifies structured data markup is present. Content analysis checks heading hierarchy and coverage. Link analysis reports internal and external links, and image analysis flags images that are missing alt text.
All of this data arrives as clean JSON — no HTML parsing, no screenshot scraping, no brittle selectors. You can pipe the response directly into your database, feed it into a CI/CD pipeline, or display it in a custom dashboard. The API is designed for machines, not humans, which means it is fast, reliable, and consistent across every call.
Whether you are monitoring your own properties or auditing clients at scale, an SEO audit API turns what used to be a hours-long manual process into a sub-second automated check. The time savings alone justify the integration, and the improved search visibility that follows is the real payoff.
