Why Page Speed Matters
Better User Experience
Fast sites retain more visitors, reduce bounce rates, and increase conversions. Every additional second of load time significantly decreases user satisfaction.
Google Ranking Factor
Page speed is a direct ranking factor, especially for mobile searches. Google prioritizes fast sites in search results.
Impact on Conversions
Faster sites have higher conversion rates. A 0.1-second improvement in speed can increase conversions by up to 8%.
