Short answer: yes. A slow website loses customers before the page finishes rendering. It costs you twice, because website speed is also a ranking factor through Core Web Vitals. The practical threshold is about two and a half seconds to show the main content on a mobile connection. Past that, drop-off climbs sharply. The usual causes, in order of impact: oversized images, unused plugins, bloated icon fonts, third-party scripts, and cheap shared hosting.
Website speed: how slow is too slow?
The practical threshold is around two and a half seconds to show the main content on a mobile connection. Past that, drop-off climbs sharply. In New York, much of your traffic arrives on a crowded network between other things. That makes the margin thinner than the averages suggest.
What actually makes a website slow?
- Images uploaded at full camera size. The single most common cause, and the easiest to fix.
- Plugins you no longer use. Each one can load CSS and JavaScript on every page, whether or not the page needs it.
- Icon fonts and script libraries loaded for one element. We routinely find 70 KB of font loading for a single arrow.
- Third-party scripts. Chat widgets, tracking pixels and embedded feeds run on someone else server, and you inherit their slow day.
- Cheap shared hosting. If the server takes a second to respond, nothing on the page can start.
What should you fix first?
Fix these in order, because that is the order of return. Compress and resize the images. Remove the plugins you do not use. Enable caching. Then remove any third-party script you cannot justify. Most sites gain more from those four steps than from anything a developer can do afterwards.
Does website speed affect Google rankings?
Yes, through Core Web Vitals, though website speed is one signal among many. The larger effect is indirect: a faster site keeps more visitors, and Google notices when people stop bouncing back to results.

If the fixes above sound like more than an afternoon, that is usually a sign the theme or host is the problem rather than the settings. Our web development agency in New York builds every site to a 90+ PageSpeed score by default, and the web design cost in New York we publish includes that work.

Common questions
How fast should a website load?
Aim to show the main content within two and a half seconds on a mobile connection. Past that, visitor drop-off rises sharply.
Does website speed affect SEO?
Yes. Core Web Vitals are a ranking signal, and faster pages also keep visitors on the site, which reinforces the ranking.
What is the quickest way to speed up a WordPress site?
Compress and correctly size the images, remove unused plugins, and enable caching. Those three usually deliver most of the available gain.
