What to inventory
Start from the list of URLs that actually exist, not from the menu. On the A1 Sure Services site the list came from the WordPress sitemaps, because the menu hid several pages. Each URL was then checked: a few were already WordPress redirects to other posts, so they became redirects again instead of pages.
- URLs and indexable pages, with their titles, descriptions and headings.
- Organic landing pages and backlinks, so you know which addresses carry search value.
- Existing redirects and crawl issues, so old problems are not carried over.
- Plugin-dependent content, forms and integrations, which have no direct equivalent in Webflow and need a decision.
What to merge or drop
An audit is also where thin and overlapping pages come out. A1 Sure Services showed both kinds:
| Found in the audit | Decision | Result |
|---|
| 257 tag archives | Thin pages, two to five posts each | Not rebuilt: one wildcard 301 sends every /tag/ address to the blog |
|---|
| 15 category archives and 1 author page | Archive pages, not rebuilt | Redirected to the blog the same way |
|---|
| Nine North Shore copies of the service pages | Overlapping pages | Folded into one North Shore hub |
|---|
| Six other overlapping pages | Overlapping pages, retired | Merged into the pages that replaced them |
|---|
What to keep, and where it goes
When an old URL is clean and still matches what the page is for, keeping it lowers the risk. A1 Sure Services kept 155 blog posts on the exact addresses they had, which is why the audit mattered: it separated the pages worth carrying over unchanged from the ones that needed a destination. Every URL that does change needs a deliberate target, a 301 redirect and internal links updated to match. On A1 Sure Services that meant 34 redirect rules, each requested once after publishing, and over 300 internal links repointed so none of them goes through a redirect.
Why do it first
The URL and redirect map is usually the highest-risk step of a migration, because it controls whether old ranking signals and links reach the right new pages. Auditing first means that map is written from the real site rather than from memory, and the launch check has something to be measured against. A1 Sure Services ended with 190 pages live on Webflow and 0 broken links on the final crawl, run before the domain was switched.
What the audit finds, such as plugin-dependent content, page-builder layouts and custom fields, is also what sizes the job, so it comes before any quote. For scope and timing, see Webflow migration cost and timeline. The full case is on the A1 Sure Services case study.
