Ecommerce Performance Q&A

What is a good conversion rate for Shopify in 2026?

While the average mobile conversion rate is approximately 1.2%, top-performing Shopify stores (the top 10%) achieve rates of 4.7% or higher.

How does site speed affect SEO rankings?

Google uses site speed (via Core Web Vitals) as a direct ranking factor. Faster stores not only rank higher but also see significantly lower bounce rates and higher repeat purchase rates.

Are social proof apps worth it for new stores?

Yes. Because shoppers who interact with reviews are 161% more likely to convert, social proof is the most effective way for new brands to build the 'reputation juice' needed to compete with established players.
