Restoring ?p=1 and ?id=42 URLs — why almost every tool gives up, and how I don't

Here is a sentence I have heard from five different site owners, in almost identical words:

“The catalog used ?id= URLs everywhere. Every other service said those pages were lost.”

They were not lost. They were ignored. There is a big difference, and it is the single most common reason a “restored” site turns out to be missing the pages that actually generate traffic or sales.

What is a parametric URL, and why does it matter?

A parametric URL is any address that uses a query string to load different content from the same path:

• example.com/blog/?p=42 — classic WordPress post ID
• example.com/product.php?id=17 — old PHP catalog
• example.com/page.php?cat=3&page=2 — paginated listings
• example.com/?s=shoes — search results

For an e-commerce site, a directory, a forum, or an old WordPress blog, these URLs are the bulk of the real content. The homepage is decoration. The ?id= pages are the product catalog, the article archive, the member profiles — the stuff someone would actually want to recover.

Why most tools skip them

Generic archive scrapers work by following links from the homepage. They hit /about, /contact, /blog, and stop. When they encounter ?p=42, three things go wrong:

1. The crawler treats query strings as duplicates

Standard crawling logic collapses /blog/?p=1, /blog/?p=2, and /blog/?p=3 into a single “page” because the path is identical. Only the first one gets saved. The rest vanish — even though they are entirely different articles.

2. The Wayback snapshot for that exact URL may be missing

Even if a tool tries to fetch ?p=42, the Internet Archive may not have captured that exact query string. It captured ?p=41 and ?p=43 on different days. Naive tools report “not found” and move on. A real recovery has to find the closest snapshot per URL, not the closest snapshot overall.

3. WordPress does not store them as pages by default

When you import the recovered HTML into WordPress, a ?p=42 address is not a page — it is a query against the post table. Dumping the HTML into a page does not restore the URL. You need rewrite rules, custom routing, or — my preferred approach — to materialize each parametric URL as a real, editable WordPress page that preserves the original address via a redirect map.

How I recover parametric URLs end-to-end

I built a capture pipeline specifically for this. It does three things a generic scraper does not:

• Discovers the parameter space. It reads the archive’s own link graph for your domain and extracts every ?p=, ?id=, ?cat= value it can find — including values only referenced from other archived pages.
• Fetches per-URL snapshots. For each discovered parameter, it queries the Wayback CDX API for the best available capture date and downloads that exact URL — not a collapsed “representative” of the path.
• Materializes each as a distinct WordPress page. Each parametric URL becomes its own editable page in WordPress, with the original address preserved through a 301 redirect map so existing links and SEO equity survive the move.

The result: a catalog that had 1,800 ?id= product pages in 2019 has 1,800 product pages in the restored WordPress today — not 1,800 lines in a CSV, not 1,800 broken links, but 1,800 pages you can open in the editor.

Why this changes the economics

Most budget restoration pricing is built around “pages” meaning “top-level navigation pages.” A 50-page site for $15 sounds fine until you realize your real site was 2,000 parametric pages and the seller’s definition of “page” quietly excluded all of them. You pay $15, get a homepage and four nav links, and then get quoted $400 to recover “the rest.”

I price by total recovered page count, up front, after seeing the archive. If your site genuinely had 300 pages, you pay the Starter rate. If it had 3,000 parametric URLs, we talk about the Standard tier. No surprise escalation halfway through.

How to tell if your site has parametric URLs at risk

Before you commission a restore, paste your old URLs into the Wayback Machine and check a few of these:

• If your old site was WordPress, look for /?p=NUMBER in archived links — those are post IDs.
• If it was a catalog or shop, look for ?id=, ?product=, ?item=.
• If it was a forum, look for ?thread=, ?t=, ?f=.
• Open the archived homepage, view source, and search for ? in href attributes. Every match is a parametric URL that needs dedicated recovery.

If you find more than a handful, send me the list. I will tell you how many are recoverable from the archive and what the real scope is — not the optimistic version a $15 gig quotes you.
