Visitors Are Impatient — Seconds Change Everything
When a potential customer clicks on your site, how long will they wait? Research shows the majority of users abandon sites that take more than a few seconds to load. On a weak phone connection, that window gets even shorter. First impressions are formed before the visitor even steps inside. If your site is slow, that impression can easily become 'I don't trust this business.'
LCP (Largest Contentful Paint) threshold for a good user experience — web.dev Core Web Vitals standard

When ranking sites, Google considers a set of metrics that measure user experience. The most important of these are three criteria known as Core Web Vitals (core web performance indicators). The technical terms may sound complex, but think of them this way: how fast does your site load, does the content stay in place or does it shift around, and how quickly does it respond to taps and clicks?
- LCP (Largest Contentful Paint): How long does the main content — a large image or headline — take to appear? Under 2.5 seconds is considered 'good.'
- CLS (Cumulative Layout Shift): Do buttons and text shift around while the page loads? Accidentally tapping the wrong element frustrates users, and Google records this as a poor experience.
- INP (Interaction to Next Paint): How quickly does the page respond when you tap a button? Under 200 milliseconds is considered 'good.'
Searches Now Come From Phones
In Turkey, the vast majority of internet usage happens on mobile devices. When someone searches for 'florist near me' or 'accountant in Bursa,' they are most likely holding a phone. If your site looks broken on that phone, buttons are hard to press, or horizontal scrolling appears, that customer will move on to a competitor. On top of that, Google applies 'mobile-first indexing': it evaluates your site's mobile version before its desktop version.
Responsive Design: A Layout That Fits Every Screen
Responsive design means your site automatically adapts to phone, tablet, and desktop screens. You do not need a separate 'm.yoursite.com' mobile version; a single site displays correctly on all screens. This approach has become the industry standard today, both for ease of maintenance and for Google compatibility.
- Image sizes: Large uncompressed images are the single biggest cause of slow page loads.
- Hosting quality: The physical location and capacity of your server directly affects how quickly the first byte arrives.
- Unnecessary plugins and scripts: Too many add-ons slow down how quickly the page is processed in the browser.
- Cache usage: Previously visited pages load faster; correct cache settings make this happen.
- Responsive CSS: Style rules that create fluid layouts based on screen size.
