The week before launch is the cheapest time to fix SEO problems and the most expensive week to skip them. Once Google has crawled a site with missing titles, broken redirects and accidental noindex tags, you spend months repairing something that would have taken an afternoon.
Run this checklist before the site goes live. It is deliberately practical: twenty items, split into five groups, each one verifiable in a few minutes.
1. Technical Foundations
- HTTPS everywhere. A valid SSL certificate installed, and all HTTP URLs redirecting to HTTPS.
- Choose one version of your domain. Decide between example.com and www.example.com, then redirect the other permanently.
- Robots.txt is correct. It should allow crawling of the site and block only what you actually want blocked — never the whole site.
- No accidental noindex. Check meta robots tags and X-Robots-TT headers on staging URLs. This is the single most common launch disaster.
- Clean, readable URLs. Use /services/website-development/ rather than query strings or page IDs.
- Canonical tags on every page, each pointing to its own correct URL.
2. On-Page Basics
- Unique title tags for every page, roughly 50–60 characters, containing the primary keyword naturally.
- Unique meta descriptions of about 140–160 characters that give a genuine reason to click.
- One H1 per page, followed by a logical H2 and H3 hierarchy that reflects the content.
- Keyword intent matched to page type. Service pages for commercial terms, blog posts for informational ones. Do not blur the two.
- Descriptive image file names and alt text on every meaningful image. Skip alt text on decorative ones only.
- Internal links connecting related pages with descriptive anchor text — and no page left orphaned.
3. Speed and Mobile
- Test on mobile first. Open every key page on an actual phone, not just a resized browser window.
- Compress images. WebP or AVIF where possible, correctly sized, with lazy loading for below-the-fold images.
- Check Core Web Vitals. Aim for a Largest Contentful Paint under 2.5 seconds, and minimal layout shift.
- Trim third-party scripts. Every chat widget, tracker and embedded video costs load time. Remove anything you do not use.
4. Redirects and Migration
- Map every old URL to a new one. If this is a redesign or replatform, a 301 redirect for each changed URL is mandatory.
- Fix broken links and 404s before launch, and set up a helpful 404 page with links back into the site.
5. Analytics, Sitemaps and Local
- Install Google Analytics 4 and Google Search Console, verify ownership, and confirm that data is being recorded on a test visit.
- Submit an XML sitemap covering all indexable pages, and keep it updated as you publish.
If you serve customers in a specific city or locality, add these three items before launch: consistent NAP details across the site, a complete Google Business Profile linked to your domain, and clickable phone and WhatsApp contact options on every page.
Quick Pre-Launch Table
| Check | How to Verify | Impact If Missed |
|---|---|---|
| No accidental noindex | View source on live URLs and inspect with Search Console | Site invisible in search |
| 301 redirects mapped | Crawl old and new URL lists side by side | Lost rankings and traffic |
| Mobile experience | Test on a real phone over 4G | High bounce, weak conversions |
| Page speed under 3s | PageSpeed Insights and Real User Metrics | Lower rankings and fewer sales |
| Analytics and Search Console live | Trigger a test visit and check the real-time report | Flying blind after launch |
| Sitemap submitted | Search Console Sitemaps report | Slow, uneven indexing |
Your First Week After Launch
- Request indexing for key pages in Google Search Console.
- Watch the Crawl Stats and Page Indexing reports for errors.
- Check that forms are delivering to your inbox or CRM, not just showing a success message.
- Monitor uptime and load time daily for the first fortnight.
- Compare first-week traffic and ranking positions against your pre-launch baseline.
The SEO Mistakes That Cost the Most
- Launching with placeholder copy such as "Lorem ipsum" left on a live page
- Staging site left indexable, or the live site left blocked from indexing
- New URLs with no redirects from the old ones
- Every page targeting the same keyword
- Titles generated automatically, producing duplicates across dozens of pages
- Large uncompressed images and four analytics scripts loading before content
Frequently Asked Questions
How soon will my new website rank on Google?
Google usually indexes a new site within days to a few weeks. Ranking for competitive keywords takes months of content, links and technical health. New domains generally need three to six months of consistent work before meaningful organic traffic appears.
Should I submit my website to Google manually?
Yes. Verify your site in Google Search Console, submit your XML sitemap, and request indexing for your most important pages. It speeds up discovery but does not guarantee rankings.
Do I lose rankings if I redesign my website?
Only if URLs change without redirects, content is removed, or speed and mobile experience regress. Keep URLs stable, redirect anything that changes, and re-check Core Web Vitals before going live.
How often should I check SEO after launch?
Daily for the first two weeks for indexing errors and form submissions, weekly for the first three months for rankings and traffic trends, then monthly for content and technical health as part of regular maintenance.
The Bottom Line
Launch-day SEO is mostly about not sabotaging yourself: indexable pages, stable URLs, redirects in place, fast mobile experience and analytics switched on. None of it is glamorous, and all of it is quick to check. Work through this list the day before you go live, verify each item, and you will start with a clean foundation instead of a repair job.
