Technical SEO and performance: how to prepare a website for Google

Publishing a website doesn’t mean it will immediately appear at the top of Google’s results.

Search engines need to find pages, understand their content, process resources and decide when those pages are relevant to a search.

According to Google, SEO helps search engines understand content and helps people find the site and decide whether to visit it.

Useful content is still the foundation

Google recommends creating reliable, useful content designed primarily for people.

A good article needs to:

• answer a real question
• present clear information
• avoid artificial repetition
• use examples
• demonstrate knowledge
• be updated when necessary
• point visitors to related content

SEO isn’t about repeating the same keyword dozens of times.

Titles and descriptions

Every page should have a unique title and a coherent description.

The title should communicate the main topic. The description should summarize the content and encourage a visit, without promising something the page doesn’t deliver.

Example — Title: "Custom Software Development | Armel-x Tecnologia".

Description: "We build custom systems and digital platforms to improve processes, integrate operations and support company growth."

Heading structure

The page should follow a clear hierarchy:

• H1 for the main title
• H2 for major sections
• H3 for subsections
• paragraphs and lists for content

Headings should represent the structure of the text, not just its visual size.

Crawling and indexing

Google works through stages such as discovery, crawling, processing and indexing.

Some important elements are:

• crawlable internal links
• XML sitemap
• robots.txt
• canonical tags
• descriptive URLs
• correct HTTP status
• no accidental blocks
• content available without requiring unnecessary interaction
• pages free of errors

Core Web Vitals

Core Web Vitals assess aspects of real user experience:

• LCP: loading of the main content
• INP: responsiveness to interactions
• CLS: visual stability

These indicators can be affected by:

• heavy images
• incorrectly loaded fonts
• excessive JavaScript
• slow servers
• components that shift position
• third-party scripts
• render-blocking resources

Optimized images

Images should have:

• correct dimensions
• modern formats
• responsive loading
• alternative text
• descriptive file names
• compression
• reserved space to prevent layout shifts

In Next.js projects, the Image component provides optimization and visual stability features while loading.

Structured data

Structured data helps search engines understand entities and content types.

An institutional website can use, when applicable:

• Organization
• WebSite
• WebPage
• Service
• Article
• BlogPosting
• BreadcrumbList
• FAQPage

It needs to represent information that is visible and true.

Search Console

After publishing, Google Search Console helps track indexing, performance, Core Web Vitals and possible security issues.

The team should monitor:

• indexed pages
• queries generating visits
• clicks
• impressions
• crawling issues
• excluded pages
• mobile performance

Conclusion

SEO is the result of combining useful content, technical structure, user experience and ongoing follow-up.

No setup guarantees the first position. However, a fast, crawlable, organized and relevant website is in a much better position to be understood and found.
