FAQ

Frequently asked questions

Do Core Web Vitals affect SEO rankings?

Yes. Google uses Core Web Vitals as part of its page experience ranking signals. Pages with good CWV scores have a ranking advantage over pages with poor scores, especially in competitive niches.

What is a good LCP score?

Google considers LCP (Largest Contentful Paint) good when it's under 2.5 seconds, needs improvement between 2.5-4 seconds, and poor above 4 seconds. LCP measures how quickly the main content of your page loads.

What causes poor CLS scores?

Cumulative Layout Shift (CLS) is usually caused by images without dimensions, dynamically injected content, web fonts causing text shifts, or ads that push content down. A good CLS score is under 0.1.

How does page speed affect search traffic?

Studies show that 53% of mobile visitors leave if a page takes over 3 seconds to load. Faster pages get better rankings, higher click-through rates, and lower bounce rates — all of which compound into more search traffic.
