Running & Configuring Performance Scans
Set your scan scope and run on demand

By default, Cromojo runs a Page Performance Scan once weekly scans are on, so you don't have to lift a finger. But you can also run a scan whenever you want, and control exactly which pages get scanned.
Run a scan on demand
On-demand scans per month: Starter 2, Pro 6, Business 15, Agency unlimited. When you reach the limit, the Re-scan button tells you so. On the Page Performance page, click Re-scan to run a fresh scan right away. There’s a monthly limit (shown as, for example, “0/6 scans used in the last 30 days”), so save on-demand scans for when you’ve just made changes and want to see the impact.
You get an email when an on-demand scan finishes or fails (Settings > Notifications).
Very large sitemaps are scanned in batches, so a single scan may cover up to 200 pages.
Choose which pages get scanned
Go to Settings → Monitoring → Page Performance Scan Scope. You have two options:
All pages from your sitemap (the default), Cromojo scans everything in your sitemap.
Only a custom list of URLs, you paste the exact pages you want scanned.
Fine-tune with include and exclude
You can narrow the scan further with patterns, one per line:
Include patterns, only scan pages that match (for example, /blog).
Exclude patterns, skip pages that match (for example, /account).
Patterns can be simple path prefixes (like /docs) or regular expressions (like /blog/.*). If a page matches both lists, exclude wins. Changes take effect from the next scan.
A tip for large sites
Don't scan everything. Narrow the scope to your most important templates, home, key product or collection pages, top blog posts. Each scan stays focused, and you stay within your monthly limit.
