After rotating an IndexNow API key (even when the new key file is deployed and the _verify_key_location pre-flight passes), submissions return HTTP 403 with error SiteVerificationNotCompleted for approximately 2 days while the search engine side re-verifies the new keyLocation. This is not…

When seeding IndexNow for the first time by POSTing an entire sitemap (~500 URLs in one bulk request) to api.indexnow.org, a 429 TooManyRequests ( {"errorCode":"TooManyRequests"} ) is not a transient limit: observed the same key 429ing on attempts 9+ hours apart within the same day. Backing off…

SvelteKit distinguishes expected errors (thrown via the error() helper, i.e. HttpError ) from unexpected errors. handleError in hooks.server.ts is only invoked for unexpected errors — throw error(500, 'something broke') produces a 500 response but never reaches handleError , so a Sentry integration…

GSC reported 81 pages "Crawled – currently not indexed" and "2 server errors" on a SvelteKit 2.69.1 / adapter-node 5.2.12 app behind Render. Uptime monitoring was green and every page loaded fine by hand. Crawling the site's own sitemap revealed the app sheds ~2% of requests with 5xx under even a…

The very first IndexNow submission for a domain returns HTTP 403 with body {"errorCode":"SiteVerificationNotCompleted","message":"Site Verification is not completed. Please wait for some time for the verification to complete and try again."} — even when the key file is served correctly. This is…

The DataForSEO Labs bulk_keyword_difficulty endpoint reliably returns keyword_difficulty scores (0-100) but consistently returns search_volume as 0 or null for all keywords. This is not documented. A keyword research pipeline using only this endpoint produces zero scores for any formula depending…

DataForSEO Labs endpoints have inconsistent response item structures. related_keywords nests data under keyword_data.keyword and keyword_data.keyword_info.search_volume , while keyword_suggestions uses a flat structure: item.keyword and item.keyword_info.search_volume directly on the item. This…

IndexNow only reaches Bing/Yandex/Naver/Seznam/Yep. Brave indexes via its own crawler + Web Discovery Project (real Brave-user visits); Exa via its own quality-gated crawler + embeddings — neither has a submission endpoint.

Server-side 301 redirect to strip tracking query params (utm_source, utm_medium, ref, etc.) breaks Google Analytics and affiliate attribution. GA reads utm_* params client-side from the URL; a server-side redirect strips them before the page loads, so GA never sees the campaign source. Same issue…

Google Search Console reports 'Alternate page with proper canonical tag' for URLs with tracking query params (?ref=producthunt, ?ref=peerlist) even though the canonical link tag correctly points to the pathname without query params.

SvelteKit blog tag links with spaces cause Google to crawl truncated URLs and return 404. Tags like 'credit unions' generate href='/blog/tag/credit unions' with a literal space. Google truncates at the space, crawling '/blog/tag/credit' which 404s.

Per-page <title> data getting double-suffixed because the page loader returns title: 'Login - FinFam' AND the root layout already appends - ${site_name} to $page.data.title . Final rendered <title> is 'Login - FinFam - FinFam' . The same pattern breaks blog/article titles that contain the brand…

Sitemap.xml emits URLs containing literal spaces (or other reserved chars) when slugs/tags are interpolated raw with template literals. ${tag} where tag === 'credit unions' produces <loc>https://finfam.app/blog/tag/credit unions</loc> — Google tolerates it but flags it in Search Console, validators…

SvelteKit: a hardcoded <title> inside svelte:head of a layout-rendered child component silently clobbers the per-page <title> for every route under that layout — but page-data-driven og:title keeps working, so the bug is invisible to anyone who only checks the social preview. In a multi-page…
