_redirects

# Redirects for Cloudflare (Workers static assets / Pages) and Netlify — all
# three read this same file format.

# /es/ and /de/ were live and listed in sitemap.xml until 2026-07-25, so they
# may be indexed. i18n is now switched off (see i18n.mjs for why), and a page
# that was in the sitemap must not become a hard 404 — that drops whatever
# equity it had and leaves anyone who bookmarked or linked it on an error page.
# 301 to the English homepage, which is what both pages ended by linking to
# anyway. Remove these only once Search Console shows the old URLs dropped out
# of the index.

# ── Page consolidation, 2026-07-29 ────────────────────────────────────────
# Search Console: 51 of 55 URLs stuck in "Discovered – currently not indexed",
# and zero Google organic sessions in the 28 days to 28 Jul. 48 of the 51
# collection pages were `format: "text"` — one tool behind dozens of prose
# wrappers — which is precisely what makes Google decline to spend crawl
# budget. 22 pages were folded into two survivors, each redirect pointing at
# the page that genuinely absorbed the content.
#
# Not a thin-content cull: these pages measured 93–95% unique prose. They were
# merged because the intent was one intent, and their specifics live on in the
# target pages' "by language" / "by format" sections.

# 16 per-language pages → code-diff. Their own descriptions said
# "language-agnostic"; the tool never had per-language behaviour to lose.

# ── Generic-synonym consolidation, 2026-08-03 ─────────────────────────────
# AdSense rejected diffhero.app for "Low value content" on 1 Aug, eight days
# after the enrichment pass — so more prose per page was not the answer.
# text-compare, compare-two-text-files and online-diff-checker were three URLs
# for one tool: all `format: "text"`, no behavioural difference between them,
# distinguished only by which synonym the copy leaned on. That is the doorway
# pattern Google's quality guidance names directly.
#
# online-diff-checker survives (highest-intent head term, and the page the
# articles already link to as "diff checker"); it absorbed both retired pages'
# guide prose, so the file-drag and prose-comparison specifics are still there.
# /embed/text-compare is untouched — live iframes on other people's sites must
# keep working, and it's noindex anyway.

# 6 config formats → config-diff, a new page carrying all six formats'
# specifics. env-diff and package-json-diff deliberately survive: the first is
# a distinct secrets-comparison intent, the second is the only other `format:
# "json"` page besides json-diff.
