A new website can look polished and still launch with weak technical SEO. Common problems include generic metadata, thin internal links, accidental crawl blocks, missing schema, or pages that feel fine on desktop but break on mobile. None of these issues are especially rare. They are just easy to miss when the team is focused on design approval and publishing deadlines.
1. Crawlability and page access
The first technical SEO job is making sure search engines can reach the right pages. That means checking robots directives, canonical tags, status codes, and whether the main site sections are actually discoverable through navigation and internal links.
- Confirm important pages are not blocked by robots rules or noindex tags.
- Check canonical tags for self-reference and consistency.
- Make sure navigation exposes the key commercial and support pages.
- Verify the sitemap lists the pages you actually want indexed.
2. Metadata and content structure
Title tags
Every important page should have a specific title that matches user intent instead of repeating the same broad brand line.
Meta descriptions
Descriptions help search engines understand the page and give the result a stronger chance of earning clicks.
Heading structure
Use one H1, clear H2 sections, and supporting H3s so the content is easy to scan and easier for search systems to parse.
Internal links
Connect primary pages to pricing, FAQs, support guides, and related services instead of leaving important pages isolated.
3. Schema, images, and semantic signals
Schema does not replace good page copy, but it helps clarify entities, page type, and FAQ content. Images also need useful alt text when they support the page content. The best results come from combining structured data with clear visible text.
- Validate FAQ, Article, Organization, or Service schema where relevant.
- Use descriptive alt text for meaningful images.
- Keep the core offer, proof, and page purpose in text on the page.
- Avoid relying on sliders, tabs, or decorative visuals as the only source of meaning.
4. Performance and mobile experience
Search visibility and user experience both benefit from pages that load quickly, stay visually stable, and work well on phones. A launch review should include more than a glance at desktop screens.
| Area | What to review | Why it matters |
|---|---|---|
| Images | Compression, dimensions, and lazy loading where appropriate | Large assets can slow key pages immediately |
| Mobile layout | Spacing, tap targets, stacked sections, and forms | Mobile is where many users and reviewers first see the site |
| Scripts | Third-party tags, analytics setup, and UI libraries | Heavy scripts can hurt speed and create instability |
| Core pages | Homepage, service pages, pricing, and contact forms | These pages usually carry the highest business risk at launch |
5. Launch-day and post-launch checks
Technical SEO does not stop once the site is live. Search engines still need to process the new site, and the team still needs clean tracking and crawl visibility.
- Submit the sitemap in Search Console.
- Request indexing for the homepage and key commercial pages.
- Review Search Console coverage and enhancement reports.
- Test the structured data again on live pages.
- Watch forms, phone clicks, and conversion events during the first weeks.
What technical SEO should be checked before a website launch?
Check metadata, headings, canonicals, internal links, schema, alt text, crawlability, mobile performance, analytics, and sitemap readiness.
What causes SEO problems on a new website?
Thin pages, generic metadata, weak internal links, crawl blocks, poor mobile experience, and skipped post-launch checks are common causes.
How soon should Search Console be checked after launch?
Immediately after launch, and then closely for the first two to four weeks so coverage, indexing, and usability issues are caught early.
Launching a new website soon?
The main service page covers development scope, pricing, and project intake for teams that want a launch-ready website, not just a design mockup.
