Planning a Blog Post Structure for Explaining Website Content Inventories and Migration Mapping
Why a Content Inventory Comes First
A rebuild usually starts with design mockups, but the real work begins with an honest audit of what already exists. A content inventory is simply a structured list of every page, image, document, video, and block of copy on the current site. Without it, teams rebuild from memory and quietly lose important material.

On design-logix.co.uk projects we treat the inventory as the contract between the old site and the new one. It answers a blunt question: what do we actually have, and where does it go? That question prevents expensive surprises later.
Cataloguing Pages, Assets, and Copy
Start with a crawl or a sitemap export, then verify it manually. Every URL should be captured with its title, meta description, primary heading, word count, and status code. Assets deserve their own columns: file type, dimensions, alt text, and usage rights.
Copy needs the most care. Record who owns it, when it was last updated, and whether it still reflects the brand. A quick rule of thumb is shown below.
| Field | Purpose | Example |
|---|---|---|
| URL | Unique identifier | /services/seo |
| Content type | Groups similar items | Landing page |
| Action | Keep, rewrite, merge, or drop | Rewrite |
| Owner | Accountability | Marketing team |
From Inventory to Migration Mapping
Migration mapping is the bridge between the audit and the new build. Each old URL is matched to a new destination, or marked for removal with a proper 301 redirect. This mapping must be reviewed by someone who understands both the content and the site architecture.
A simple workflow keeps the process calm:
- Freeze the inventory once the crawl is verified.
- Assign an action to every row.
- Map each kept URL to a new path.
- Redirect anything without a direct replacement.
Common Mistakes to Avoid
The most frequent error is treating the inventory as a one-off spreadsheet that nobody updates. Content changes weekly, so the inventory should live in a shared document with a clear owner. Another mistake is ignoring hidden assets such as PDFs and legacy blog images.
Also resist the urge to keep everything. A rebuild is a chance to prune, and a shorter inventory is easier to map and maintain.
An inventory is not paperwork; it is the map that keeps a rebuild from losing its way.
Making the Structure Repeatable
Use a consistent template for every project so comparisons stay easy. Columns, naming conventions, and action codes should be identical each time. A short checklist before launch catches broken redirects and orphaned pages.
- Every URL has an action.
- Every redirect resolves to a live page.
- Owners are named for rewritten copy.
Done well, this structure turns a chaotic rebuild into a predictable, reviewable process that protects both rankings and brand voice.
