Is this really free?
Yes, and there is no email required to see the result. The report renders on the page. If it is useful and you want the whole site looked at rather than one page, the 15-minute teardown is also free.
What would a rebuild break on your site?
When a redesign loses traffic on launch day, the design is rarely the reason. Paste a URL and this free check looks at the things that decide whether a new platform keeps its rankings.
What it looks at
- Canonical host
- Whether the canonical tag points at this site or somewhere else. A canonical still aimed at a staging host is the most common reason a site vanishes after launch.
- Indexability
- The robots meta tag and the X-Robots-Tag header, either of which can quietly remove a page from search.
- Redirect chains
- How many hops sit between the address you typed and the page that finally loads.
- Structured data
- Which JSON-LD types the page emits. Whatever is there has to be reproduced in the new templates, and it is one of the most commonly dropped things in a rebuild.
- Image formats and dimensions
- How many images use legacy formats or ship without width and height, which is where layout shift and most wasted bytes come from.
- WordPress upload paths
- References to /wp-content/uploads/. Those URLs are indexed in Google Images and embedded on other people's sites, so they have to keep resolving after a move.
- robots.txt and sitemap
- Whether both exist and whether robots.txt declares the sitemap. After a migration that is how Google finds the new URLs.
Questions
Does it crawl my whole site?
No. It fetches the single page you give it, plus robots.txt and a sitemap probe. That is enough to surface the failure patterns that cost sites traffic, and it keeps the tool fast and light on your server. A full crawl is what the teardown is for.
Will it slow my site down or show up in analytics?
It makes at most three requests and identifies itself as IdreesworksMigrationCheck in the user agent, so you can see exactly what it did in your logs. That is less load than one person visiting your homepage.
My site scored well. Does that mean a migration is safe?
It means this page has no obvious faults, which is a good start and not a guarantee. The risk in a migration is concentrated in the URLs a homepage never links to: attachment pages, faceted filters, retired campaign pages, and anything with inbound links nobody remembers. Only a crawl finds those.
Planning a real move? The migration service covers the crawl, the redirect map, and the coverage checks after launch. If you are leaving WordPress, the WordPress to Next.js page goes through the traps specific to that platform.
