To restore a large blog archive without duplicate imports, identify the original articles before importing files. Several captures, listing pages and URL variants can refer to the same writing. Build an article-level ledger, select supported versions and check the intended destination before creating a post.
A larger archive needs better reconciliation, not looser evidence standards. The workflow below is a planning method, not a claim that thousands of articles were recovered or that a particular importer prevents duplicates automatically.
Separate discovery URLs from article identities
Start with the available URL inventory, then classify article pages, category listings, pagination, feeds, search results, media and other page types. Keep discovery records, but do not automatically convert every HTML page into a blog post.
A listing may repeat an article’s opening paragraphs. A print view may present the same article differently. Query parameters or hostname variants can create more observations without establishing more original articles.
Assign a stable working identity to each supported article and retain the historical paths associated with it. Do not discard a useful variant before checking whether it represents distinct content or a genuinely different edition.
Build the article ledger before the import queue
This blank record is a suggested recovery utility, not a completed publisher migration. For each candidate article, keep:
- Working article identity and historical public URL.
- Title, supported byline and displayed publication date.
- Capture or original-source date, kept separate from publication date.
- Chosen content version and completeness status.
- Required images or documents and supported relationships.
- Existing destination match, if any.
- Approved delivered URL and import/review result.
- Unresolved issue, exclusion reason or owner decision.
The ledger must connect the source to the resulting record. A progress counter alone cannot explain whether a missing article was excluded, partially reconstructed, duplicated or overlooked.
Check duplicate candidates with more than one signal
Compare historical identity, title, body and intended destination together. Matching hashes of consistently normalized article bodies can flag identical text for review. Near-duplicate wording needs a separate similarity comparison and editorial inspection; a fingerprint alone is not permission to merge or delete articles.
Compare the article body rather than the full page wrapper where possible. Shared navigation and footer text can make unrelated pages appear similar. Conversely, tracking code or a changed sidebar can make captures of the same article appear different.
Inspect candidates with different dates or URLs. They may be revisions, syndicated editions or separate pieces with repeated passages. Keep the distinction supported by evidence; do not collapse records solely because titles match.
Before each import batch, compare its approved destinations against the current CMS inventory and the accepted earlier batches. A restart should resume unresolved work rather than create a second set of already accepted posts.
Select an editorial version without padding gaps
Classify content as complete enough for review, partial and awaiting further sources, or unsuitable for publication. Check the beginning and end of the body, embedded material and important references.
An index excerpt is not a complete article. Do not generate new paragraphs to make a partial recovery meet a word target. If the owner commissions new writing, document it as new material instead of presenting it as the lost original.
When captures show revisions, record the selected version and why it was chosen. Do not build a composite that mixes superseded facts from several dates without explicit editorial review.
Preserve evidenced relationships, not guessed private records
Maintain supported authorship, publication dates and topic relationships. A visible author name is not proof that the original private account or its permissions can be recovered. A tag shown on one capture is not proof of every historical membership.
Check media references against the usable files and the article where they appear. Keep featured-image decisions separate from inline media associations. Do not assign an image to many posts merely because its filename seems related.
Public archives do not establish private editorial drafts, approval workflows or unpublished revisions. Keep those gaps separate from the delivered public publication.
Use a representative import pilot
Choose records that exercise relevant page structures: a long article, a media-rich piece, a linked document and a materially different template where those exist. Check the extraction and destination records before expanding.
WordPress’s Tools Import documentation describes importers for particular source formats, including WordPress exports. It does not establish that a directory of downloaded archive HTML is already a valid WordPress export. Match the method to the genuine source and approved preparation process.
Use an isolated, authorized review arrangement and retain a pre-import reference. After the pilot, verify title, body, dates, media, relationships and exact public paths. Check representative owner edits through the actual delivered editor.
Do not install a tool or execute a bulk import simply because a checklist recommends a pilot. The implementation needs its own approved method and safeguards.
Keep public URL decisions explicit
Each article needs an approved destination that does not compete with an existing equivalent owner. Preserve useful historical paths where feasible and separately review exceptions.
Google’s canonicalization documentation explains signals for duplicate or very similar public pages. Those signals are not a substitute for preventing accidental duplicate CMS imports. Do not create duplicate posts first and assume a canonical tag repairs the editorial and maintenance problems.
Check that internal article and listing links point to the intended delivered owner. Do not change URLs, redirects or indexing directives automatically while resolving uncertain identity matches.
Reconcile the final coverage record
Every identified unique article should have one final status: accepted as restored, partial and pending, excluded with approval, or unavailable from the assessed sources. Reconcile those statuses against the identity inventory, not the raw number of captured URLs.
Retain source references, delivered IDs and destinations, QA results and exclusions. Treat a missing result as an unresolved record, not an assumed successful import. Review exceptions after every batch so that a small mapping error does not propagate.
The Wayback-to-WordPress guide explains the broader rebuild distinction. For a large publication, article identity and evidence-led reconciliation should govern the process, not a target post count.
Large archive questions
Should every captured URL become a post?
No. Listings, media and multiple observations of one article need classification first.
Can a content fingerprint decide what to delete?
No. Use it to find review candidates alongside identity, source dates and destination records. Changes to distinct published content need separate approval.
Can a canonical tag prevent duplicate imports?
No. It is a search-related signal for public pages, not an import identity or editorial quality check.
