The SEO Checklist to Run Before You Launch
A dozen things worth checking on your product page before launch day — while a fixable mistake is still cheap to fix and hasn't been indexed by Google in its broken state yet.
Most SEO checklists are written for sites that already have months of content and traffic. This one isn't — it's the dozen or so things worth checking on your product page before launch day, when a fixable mistake is still cheap to fix and hasn't yet been indexed by Google in its broken state.
Title and meta description
Your <title> tag should land between 30–60 characters — long enough to be descriptive, short enough that Google doesn't truncate it in search results. Your meta description should run 50–160 characters and actually describe what the page offers; a missing or auto-generated description is a small but real miss on click-through rate.
Exactly one H1
Every page should have exactly one <h1>. Zero H1s means search engines have no clear signal for the page's main topic; more than one dilutes that signal. This is one of the most common issues on hastily-shipped landing pages — a hero headline styled as an H1 and a second "big text" section elsewhere that's also accidentally an H1.
HTTPS, viewport, and the basics
These sound too obvious to check, but they're also the most common things to silently break during a rushed deploy:
HTTPS — served securely, no mixed-content warnings.
Viewport meta tag — without it, mobile rendering breaks, and mobile is most of your launch-day traffic.
Charset declared and
langattribute set on the<html>tag — small technical-SEO signals that are easy to forget and easy to fix.
Make sure the page is actually indexable
Check for a stray noindex in your robots meta tag — staging-environment settings accidentally carried into production is a genuinely common way for a launched page to be invisible to Google from day one, with no error message anywhere to tell you it happened.
Canonical URL
A self-referencing canonical tag prevents duplicate-content confusion if your page is reachable through more than one URL variant (with/without trailing slash, with/without query parameters from a launch platform's referral tracking, etc).
Open Graph and Twitter Card tags
This is the set of tags that controls how your link looks when shared on social media or in launch communities — og:title, og:description, og:image, and twitter:card. On launch day, your link gets shared far more than it gets organically searched; a missing or broken preview image is a real, avoidable drop in click-through on every share.
Structured data (schema markup)
JSON-LD structured data isn't required to launch, but it's what makes your page eligible for rich results (ratings, FAQ snippets, breadcrumbs) in search. It's cheap to add and easy to forget under launch-day time pressure.
Alt text on images
Every meaningful image should have descriptive alt text — for accessibility first, and as a secondary SEO signal second. Decorative images can use empty alt text intentionally; content images (screenshots, product shots) shouldn't be left blank.
Run it before you submit anywhere
You don't need to manually check each of these one by one — LaunchZone's free SEO Analyzer runs through all of them (title, meta description, headings, HTTPS, viewport, indexability, Open Graph, Twitter Card, structured data, and image alt coverage) and flags what's missing before you submit your launch anywhere.

Questions this article answers
Do I need perfect SEO before I launch?
No — most of this checklist is about avoiding easily-fixed mistakes, not achieving perfection. A missing meta description or alt text won't sink a launch; a stray noindex tag or a broken mobile viewport can meaningfully hurt one.
What's the single most common mistake on this list?
A leftover noindex directive from a staging environment is the most damaging because it's invisible — the page looks completely normal to a human visitor while being fully hidden from search engines.
Does structured data actually matter for a brand-new page?
It won't affect rankings on day one, but it's what makes a page eligible for rich results (FAQ snippets, ratings, breadcrumbs) later — worth adding once, rather than retrofitting after launch.
