Performance isn't a luxury: it's money
A slow site loses customers before they've even seen your offer. Studies converge: past about three seconds of loading, a significant share of visitors leave, and the rate climbs with each extra second. Google made it a ranking factor (the Core Web Vitals). In other words, slowness costs you twice: in lost visitors and in lost visibility. The good news: on a small site, speed is fixable with a few simple moves.
The speed levers within your reach
- Compress images. This is, by far, the number one cause of slowness. Reduce the weight before uploading: TinyPNG, Squoosh, or your builder's built-in compression. Serve modern formats (WebP, AVIF) — most builders do this automatically.
- Size images to the right dimensions. Loading a 4000px photo to display it at 600px wastes loading time. Resize beforehand.
- Limit fonts and scripts. Every custom font and every external widget (chat, pop-up, tracking) slows the page. Keep the essentials.
- Lean on the builder's hosting. Framer, Webflow, Shopify serve your pages from a fast global network (CDN) with no setup on your part. On WordPress, choose a good host and a cache (the WP Rocket plugin or equivalent).
Measure with PageSpeed Insights or GTmetrix (free): they score your site and list precisely what slows it down. Aim for green on mobile.
Mobile first, not optional
The majority of your visitors arrive on a smartphone, and Google indexes the mobile version of your site first (mobile-first). A site that "works" on mobile isn't enough: it must be designed for it. Check on your own phone that text is readable without zooming, that buttons are big enough for the thumb, that nothing overflows horizontally, and that forms fill in easily. Builders show a mobile preview: use it systematically before publishing, and fix what breaks.
Trust: what makes people click "buy"
A visitor who doesn't know you looks for reasons to distrust. Give them reasons to feel reassured:
- Real contact details: an email, ideally a phone number or address. A site with no contact method is unsettling.
- Social proof: reviews, testimonials with a real name and, if possible, a photo, client logos, numbers. Nothing reassures like another satisfied customer.
- A clear policy: refunds, delivery, what happens after purchase. Uncertainty blocks the decision.
- The HTTPS padlock and, for a store, recognized payment logos. Simple visual signals, but decisive.
GDPR compliance: the bare minimum
In Europe, as soon as your site collects data (a form, an audience measurement, a cart), you have obligations. The minimum to put in place:
- A "Privacy Policy" page explaining what data you collect, why, for how long, and people's rights.
- Legal notices identifying the site's publisher (mandatory in France).
- A compliant cookie banner if you use non-essential trackers (advertising, cookie-based analytics). Tools: Axeptio, Cookiebot, tarteaucitron (free, French). Consent must be free: a real "refuse" button at the same level as "accept."
- Consent on forms: unchecked box, clear purpose (seen in chapter 8).
Tip: prefer a privacy-friendly analytics tool like Plausible or Matomo, which measures your traffic without cookies and exempts you, in many cases, from the banner — while staying far simpler than Google Analytics.
The maintenance routine
A site isn't a piece of furniture: it lives. Set aside a few minutes a month to check that links work, that the payment and booking buttons still function, that the content (prices, hours, offer) is up to date, and — on WordPress — that updates and backups are done. An abandoned site ends up broken, and a broken site drives people away.
Key takeaways
Make your site fast by compressing and sizing your images and limiting scripts, design it for mobile first, and inspire trust through real contact details, social proof and clear policies. Lay the minimum compliance — privacy, legal notices, a compliant cookie banner, consent — and prefer cookieless analytics. It's the invisible layer that silently decides whether your presence converts or repels.
