Failure mode: returning 200 on a page that says 'no results'

Search and filter templates often render "0 results found" with a 200 status. Google catalogs these as soft-404s, and a wall of them lowers trust in the whole template. The status code is lying about the page's value.

Zero-result SOP:
— Step 1. Owner: dev. If the result set is empty after filtering, return 404 (or 410 if permanently gone), not 200.
— Step 2. Owner: dev. For near-empty (1-2 results) pages, either noindex or merge into the parent — define the threshold per template.
— Step 3. Owner: SEO. Crawl edge cases: filters that return nothing. Gate: every empty page returns 404/410, never 200 + noindex-only.
— Step 4. Owner: SEO. Watch GSC "Soft 404". Gate: count trends to near-zero within two crawl cycles.

Guardrail: the HTTP status must tell the truth about whether the page has content.

Ship gate: don't publish until all boxes are checked.

Mistake: letting Google index your internal site-search results

Leaving /search?q= crawlable lets Google (and your own auto-linking) generate infinite low-quality result URLs from every query string. Classic index bloat — and Google has flagged indexable internal search as a quality issue for years.

Search-results SOP:
— Step 1. Owner: dev. Block /search and any query-param result route in robots.txt AND add noindex on the rendered page (belt and suspenders).
— Step 2. Owner: dev. Never auto-link to a search-result URL from a programmatic module — link to curated category/hub pages instead.
— Step 3. Owner: SEO. site: query for indexed search URLs. Gate: zero search-result URLs in the index.
— Step 4. Owner: SEO. Confirm no sitemap entry contains a query-string result URL.

Guardrail: internal search is a feature for users, never a page type for crawlers.

Ship gate: don't publish until all boxes are checked.

ЕЮ Иванов продолжает кошмарить АффПапу, конторку, которая накинула говна на вентилятор этим летом. Тогда в AffPapa не знали, с каким говном идут бодаться, поэтому заслуженно проиграли. 😏

На этот раз ЕЮ зарегал товарный знак AffPapa — совсем скоро имя компании будет официально принадлежать ему. Чтобы убедиться в трушности мува, переходим по ссыл-Очке и вводим серийный номер: 2026793242. Там видим, что заявка на регистрацию подана лично Евгением Юрьичем.

Всё это выглядит забавно, но давайте не забывать, в какой сфере мы работаем и что реально может произойти с жирным троллем за воровство нейминга. Впрочем, толстому не привыкать отхватывать пиздов за проделки в интернете, поэтому ждем очередную фотку разбитого ебала и длинный пост с извинениями. 😏😏😏

Failure mode: one data source with no validation between fetch and render

The upstream API changes a field name or returns nulls during an outage; your nightly build renders 30k pages with "undefined" or blank stats and pushes them live before anyone notices. The pipeline trusted the source blindly.

Data-contract SOP:
— Step 1. Owner: data. Define a schema contract for the source: required fields, types, ranges. Validate the payload before it touches the template.
— Step 2. Owner: data. Set sanity bounds (row count within X percent of yesterday, no field >50 percent null). Breach = abort the build, keep yesterday's pages live.
— Step 3. Owner: dev. Render from a validated snapshot, never directly from the live API at request time for static fields.
— Step 4. Owner: SEO. Post-build smoke test: grep rendered HTML for "undefined", "null", "NaN". Gate: zero hits.

Guardrail: a failed validation freezes yesterday's good pages; it never ships today's broken ones.

Failure mode: 'related pages' modules that link by recency, not relevance

Auto-related blocks filled with "newest pages" or random rows spray link equity across unrelated topics and confuse the topical clustering you're trying to build. The module is busy work, not a signal.

Related-link SOP:
— Step 1. Owner: data. Define relatedness from data: same category + nearest attribute (geo distance, price band, shared tag). Score and rank candidates.
— Step 2. Owner: dev. The related module pulls the top N by that score, deterministically, so it's stable across rebuilds.
— Step 3. Owner: SEO. Audit 30 pages' related blocks. Gate: >= 80 percent of related links are in the same topical cluster.
— Step 4. Owner: SEO. Confirm no page links to itself and no orphan-only targets get all their links from one hub.

Guardrail: internal links flow along data relationships, never along publish date.

Ship gate: don't publish until all boxes are checked.

Mistake: shipping a template change with no way to undo it

A template tweak goes live across 40k pages, tanks indexation or breaks a schema, and the team realizes there's no clean revert — the old render is gone and the data has moved on. Recovery becomes archaeology.

Rollback SOP:
— Step 1. Owner: dev. Version every template; keep the prior version deployable behind a flag.
— Step 2. Owner: dev. Snapshot rendered HTML for a fixed 500-page canary set before and after each template change.
— Step 3. Owner: SEO. Define the rollback trigger up front: e.g. canary indexation drops >15 percent or schema-valid rate falls below 99 percent within 14 days.
— Step 4. Owner: dev. Rehearse the revert once on staging so it's a flag flip, not an emergency.

Guardrail: no template change ships without a named rollback trigger and a tested revert path.
