## **🗺️ Overview**

When you migrate your site to a new build — even if the URLs remain the same — OTTO needs to re-analyse the updated pages before it can deliver accurate recommendations. This article explains how to trigger a fresh OTTO analysis and how OTTO handles 301 redirects after a migration.

## **🧭 How to Trigger a Fresh OTTO Analysis**

After completing your site migration and confirming that your 301 redirects are live, navigate to OTTO SEO → All Sites (SEO Automation) in your Search Atlas account and trigger a new analysis for the relevant site. OTTO will begin crawling your site and refreshing all audit data based on the current state of your pages. Depending on your site size, this process may take some time, and the dashboard will update when it is complete.

Once the analysis is complete, OTTO's task list and recommendations will reflect your migrated site's current content and structure.

## **⏱️ How Long Does It Take for OTTO to Recognise 301 Redirects?**

OTTO does not automatically detect 301 redirects in real time. Recognition happens when a new crawl is triggered manually. Here is what to expect:

- **Immediate effect:** Triggering a new analysis right after migration starts a fresh crawl that takes your current 301 redirects into account.
- **Previous suggestions:** OTTO may retain audit items tied to old page states until the new analysis completes. Once the run finishes, outdated suggestions are replaced with findings based on the redirected and migrated pages.

## **✅ Best Practices Before Running the Analysis**

To get the most accurate results from OTTO after a migration, confirm the following before triggering a new analysis:

- All redirects are correctly implemented and live.
- The migrated site is fully accessible — not behind a staging password or maintenance mode.
