A craftsman who is revamping his showcase website after three years without updates discovers that half of his visitors leave the homepage within seconds. The problem does not stem from the content, but from technical choices made hastily during the creation of the professional website. Loading times, page structure, absence of markup: these neglected details from the start are costly in terms of visibility on Google and lost clients.
Structured Data and Visibility Against Generative AIs
We often talk about classic SEO, but the game has changed. Google published an official guide on May 15, 2026, to optimize your site against AI, in the same section as its SEO Starter Guide. Specifically, the share of traffic coming from search engines is being eroded by AI Overviews and responses generated by AIs.

For a professional site, this means that the content must be readable by both humans and machines. We structure our pages with clear FAQs in HTML, use natural language in our paragraphs, and mark up our data (Schema.org for hours, services, reviews). A site with well-marked content is more likely to be cited in an AI response than a site with a beautiful design but opaque code.
Agencies like BestWeb specifically work on this interplay between website creation and technical optimization for current search engines.

Cookie Compliance and GDPR on a Professional Site
The majority of SME showcase sites still display a minimalist cookie banner with a single “Accept” button. However, the CNIL requires a real “Reject All” button at the same visual level as the acceptance button, the prohibition of pre-checked boxes, and the framing of dark patterns.
Ignoring these rules exposes one to checks and fines. In practice, many site creators use cookie plugins configured by default, without verifying their actual compliance. Checking the compliance of your cookie banner before going live is part of the often-forgotten steps in the creation process.
For companies targeting the Quebec market, Law 25 imposes additional obligations: privacy incident register, detailed privacy policy, explicit consent. Feedback on this point varies by industry, but it’s better to anticipate than to correct in an emergency.
Technical Performance: What Really Slows Down a Website
When auditing a slow site, the culprit is rarely the server. It’s uncompressed images, Google Fonts loaded in five variants, and JavaScript scripts from unused plugins that weigh down loading times.
Here are the items to check as a priority when creating your site:
- Images: systematically convert to WebP or AVIF, with a target weight under 200 KB per visual. A tool like Squoosh is sufficient; no need for a paid subscription.
- Fonts: limit to a maximum of two font families, hosted locally rather than called via Google Fonts, to avoid external requests.
- Third-party plugins and scripts: each WordPress extension or external widget (chatbot, carousel, additional analytics) adds weight. Remove any plugin that does not serve a measurable purpose is the basic rule.
- Browser cache: configure expiration headers so that returning visitors do not reload the entire site on each visit.
A fast site improves user experience and its ranking in Google search results. The two are linked since Core Web Vitals became part of ranking criteria.
The Trap of the “All-in-One” Theme
Premium WordPress themes sold with dozens of built-in features (slider, portfolio, form, WooCommerce) load code even when those modules are not used. You end up with a showcase site of five pages that weighs as much as an online store with two hundred products.
Choosing a lightweight theme and adding only the necessary functions allows you to maintain control over performance. GeneratePress, Kadence, or a custom theme remain reliable options.
Page Architecture and Internal Linking for SEO
A professional site of five to fifteen pages does not require a complex structure. However, the way these pages are linked to each other radically changes their indexing by Google.
The principle: each service or offer page must be accessible within two clicks maximum from the homepage. We link the pages together with descriptive anchors in the content, not just via the navigation menu. This internal linking distributes the “SEO juice” and helps search engines understand the site’s hierarchy.
In terms of content, each page targets a distinct primary keyword. Publishing three pages that aim for the same query creates cannibalization: Google no longer knows which one to promote. One page, one target keyword, one clear conversion goal remains the most effective framework.
Writing for Visitors, Structuring for Google
An introductory paragraph that presents the client’s problem, H2 and H3 subheadings containing the searched keywords, short sentences in natural language: this structure serves both visitors and SEO. The title and meta description tags of each page should be manually written, not left to auto-generate by the CMS.
- Title: between 50 and 60 characters, with the main keyword at the beginning of the tag.
- Meta description: between 140 and 155 characters, customer benefit-oriented to encourage clicks.
- URL: short, without numbers or special characters, readable by a human (example: /creation-site-web-professionnel).
Optimizing the creation of your professional website is not just about design or platform choice. The sites that convert their visitors into clients are those whose technique, content, and regulatory compliance have been considered from day one, not added later when traffic stagnates.
