SEO checklist before launch: meta, robots, SERP, OG
Generate meta tags, test robots.txt, preview SERP snippets, and debug Open Graph HTML locally before a page goes public.
Published 2026-08-07
Launch-day SEO mistakes are boring and expensive: a Disallow that blocks the page, a missing og:image, or a title that truncates into nonsense. A local checklist catches those before crawlers and social platforms cache a bad first impression.
1. Ship a complete head snippet
Use Meta Tag Generator for title, description, canonical, Open Graph, and Twitter tags. Prefer absolute https URLs for canonical and og:image. Keep titles near 50–60 characters and descriptions near 150–160.
2. Preview the snippet
SERP Preview shows a desktop-style card and flags overlong titles or descriptions. Front-load the value proposition — mobile budgets are tighter than desktop heuristics.
3. Prove crawl rules
Paste your robots.txt into Robots.txt Tester with the launch path (or full URL). Confirm ALLOWED for indexable pages and that staging Disallow: / never shipped to production.
4. Debug social tags from source
Paste view-source HTML into Open Graph Debugger. Fix missing og:title / og:image, relative image URLs, and missing twitter:card before you rely on Slack or LinkedIn unfurls.

Frequently asked questions
Do these SEO tools crawl my staging URL?
No. Paste fields, robots.txt, or HTML. That keeps private staging pages offline and off third-party scrapers.
Will SERP Preview match Google exactly?
No. It uses common character budgets as a planning aid. Google measures pixels and may rewrite titles.
