Build a directory people can verify

Define one record before importing hundreds

Write an inclusion rule that a second editor can apply. For example: tools that a small service business can use to prepare or send client invoices. Define what counts as an invoicing capability, which regions matter and whether a listing is a product, an integration or a template.

Give each record a stable ID, product name, official URL, category and the task it supports. For each factual claim, store its source, the date it was actually checked and any currency, billing or plan scope. Keep editorial judgments in separate fields with their supporting criteria. A source reading establishes what the provider documents; it does not establish a hands-on result.

The Google Sheets profile shows why this distinction matters: its linked workflow record covers a limited invoice-tracker exercise and states its boundaries. It is not a full product benchmark or a test of Gemini.

Choose the simplest publishing path

A maintained spreadsheet or versioned data file can feed static pages when one editor owns the collection. Use a database and authenticated editing when concurrent updates, private submissions or an approval queue require them. Investigate Supabase or Airtable against those needs; neither is a prerequisite for a directory.

Publish a useful page for each record you can explain. Give categories and records ordinary links with destinations: Google’s crawlable-link guidance describes anchors with an href. Do not make the only route to a product an onclick handler or a search result that disappears without JavaScript.

Decide which categories deserve their own page. Google documents how filter combinations can expand the crawl space. Let users filter freely without automatically publishing every combination of category, price, region and sort order as a new indexable landing page.

Test the task, not just the product name

“Send invoices to clients”

Return records that meet your documented capability rule. Explain when an entry needs an integration or lacks recorded evidence.

A synonym or a misspelling

Try the terms your audience uses, record gaps and add justified synonyms to the search data.

No matching records

Show the active filters and a clear reset. Offer a useful nearby category without pretending there is an exact match.

A duplicated or withdrawn product

Merge stable IDs or retire the record with a clear destination; preserve inbound links where a relevant replacement exists.

An official source fails

Keep the last observation with its original date, mark the unresolved check and investigate. A failed fetch must not renew verification.

Make corrections part of the product

Provide a visible way to report an error. Queue the claim, its source and the proposed correction; keep a record of what changed. Check outbound links, exports and a full rebuild so a corrected record does not leave old text on its profile, category or comparison page.

If you accept paid listings, label placement and keep it separate from editorial rank. Set a review cadence you can sustain for the collection’s size. Measure unanswered searches and correction turnaround before treating the total listing count as success.

Budget editorial time alongside hosting, storage, search and any submission tooling. The directory remains useful only while its most important claims can be traced and its uncertainty is visible.
