Good SEO is what Google understands. Not what you see.

Many companies evaluate the optimization of their website through criteria such as:

• loading speed (rated on Google PageSpeed or GTmetrix),

• the quality of the design,

• the fluidity of navigation,

• the presence of keywords in the content.

These elements are of course important. But when it comes to SEO, they are secondary if the technical foundations are not respected.

Google isn’t a human being: it doesn’t “see” your site. It analyzes it, crawls it, indexes it, and interprets it according to algorithmic logic. So, what matters is what it can understand and process .

What Google Really Understands About a Website

Behind every site, Google seeks to answer this question:
“Does this content accurately address the user’s search intent in a reliable and structured manner?”

Here’s what Google actually observes:

• HTML Architecture and Content Hierarchy
  (correct use of H1, H2, H3 tags, clear semantics, logical sections)

• The quality of internal links
  (smart navigation, reasonable depth, relevant mesh)

• Technical tags
  (title, meta description, ALT tags, canonical, structured data)

• The actual server-side load time , not just what the front-end shows

• Error handling
  (404 pages, 301 redirects, sitemap, robots.txt, HTTPS security)

• URL consistency and readability

• Mobile compatibility and accessibility

• User experience (UX) measured
  (bounce rate, time spent on page, internal clicks, conversions)

In short, Google judges what it can crawl, index, and interpret – not what is only visible or felt by the end user.

SEO is an evolving process, not a single step

Another common mistake is to believe that SEO is done once, when the site is launched, and then that it remains effective for life. In reality, SEO is an ongoing process , which requires regular adjustments to remain relevant in the face of:

• to algorithm developments (Google Core Updates),

• to new competitors,

• to changes in Internet user behavior,

• to the transformations of your own business (new services, new targets, repositioning).

A poorly designed, rigid website, or one that relies on external tools (plugins, unoptimized themes, poorly configured CMS) will quickly put a spanner in the works. You’ll be forced to correct structural errors or redo entire sections of your site, which will generate additional costs and waste time.

Why a custom website makes a real difference

A custom-designed website, with an SEO strategy built in from the start, gives you a head start over your competitors.

At Prositeweb, our approach is based on three pillars:

1. A structure designed for Google

We use a design system (Phoenix) that allows us to generate reusable, lightweight, and fully controllable components. This facilitates SEO-friendly architecture from the very first line of code.

2. Independence from heavy or limiting plugins

Most WordPress plugins used for SEO offer valuable features, but often introduce unnecessary code, conflicts, or slowdowns. A custom-built site allows for fine-grained optimization without the technical overhead.

3. A scalable platform

We build systems that you can adapt to your future needs: adding new sections, implementing multilingual content, automating the generation of metadata or semantic markup, integrating tracking APIs, etc.

Result: your site is faster to index , more understandable for Google , and more efficient over time .

In conclusion

SEO is a technical, strategic, and evolving science. It’s not enough for a site to be attractive or fast to rank well. It must perfectly meet search engine requirements while effectively serving your business objectives.

By opting for a tailor-made, scalable, and technically sound solution, you give yourself the means to build a solid, sustainable, and profitable SEO.
