# Technical SEO

Technical SEO is the infrastructure work that lets search engines and AI crawlers crawl a website without problems, index it correctly and load it fast. Roicool's technical SEO service covers crawling and indexing, site speed and Core Web Vitals, structured data, multilingual setup and site migrations, delivered together with the development team.

- A large share of your pages is not indexed, or Search Console shows many errors.
- The site is slow; Core Web Vitals scores are poor.
- The same content appears on more than one URL; there are canonical and parameter issues.
- You are planning a site migration, a platform change or a redesign.
- Your content loads with JavaScript and is not visible in the server HTML.

### Crawling and indexing

robots.txt, sitemaps, canonicals, redirects, status codes, parameter URLs, pagination and orphan pages. Deciding access for AI crawlers (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and others).

### Speed and Core Web Vitals

Reviewing LCP, INP and CLS with field data; fixing bottlenecks in images, fonts, scripts and on the server.

### Structured data

Setting up schemas such as Organization, Service, Article, BreadcrumbList and FAQPage as a single graph, consistent with the visible content.

### Rendering and content access

Making sure content and links are in the server HTML; checking content in tabs, accordions and click-to-load elements.

### Multilingual setup

URL structure and hreflang; details on the [international SEO](https://www.roicool.com/en/services/international-seo) page.

### Site migration

URL inventory, 301 map, launch-day tests and monitoring afterwards. Checklist: [site migration SEO checklist](https://www.roicool.com/en/blog/website-migration-seo-checklist).

1. **Crawl and review (1–2 weeks):** site crawl, Search Console, log files (if available), template review.
2. **Priority list:** impact, effort and owner for every finding.
3. **Implementation (ongoing):** developer tasks, testing and validation.
4. **Monitoring:** monthly tracking of indexing and speed; checks on new releases.

## FAQ

### Are technical SEO and an SEO audit the same thing?

An SEO audit is a one-off snapshot of the current state. The technical SEO service covers fixing the findings, implementing them with the development team, monitoring for new issues and checking site changes from an SEO point of view.

### How much do Core Web Vitals affect rankings?

Google uses Core Web Vitals as one of its page experience signals, but they do not replace the relevance of the content. Poor scores usually hurt conversion rates too, so improving them makes sense for both SEO and the business.

### Do JavaScript sites have SEO problems?

They can. Google can process JavaScript, but having the content and links in the server HTML makes crawling more reliable. Some AI crawlers do not process JavaScript, so this also matters for GEO.

### Can technical SEO be done without a development team?

Some fixes can be made through CMS settings; template, server and performance changes need a developer. If you have no development team, we can also take on the implementation for Webflow or custom-coded sites.

### Do you support site migrations?

Yes. The URL inventory, the 301 redirect map, launch-day tests and monitoring afterwards are among the most critical parts of the technical SEO service.
