Have you ever visited a website but navigated away because the product page wasn't loading fast enough? So we built this app to solve that problem & help merchants prevent lost sales. When your customers move their mouse cursor over a link, we tell their browser to pre-load that page in the background. This results in much faster loading times. Using browser preloading technology, this app will increase load speed significantly. Faster page speed, means improved add-to-cart conversions.
Is this app really free, or will I get hit with charges after installing?
Booster Page Speed Optimizer is completely free — the Shopify App Store listing shows a price of 'Free' with no paid tiers mentioned. There are no subscription fees or hidden costs to use the app.
How does it actually speed up my store — what's the technology behind it?
The app uses browser preloading technology: when a customer hovers their mouse cursor over a link, it tells their browser to pre-load that page in the background. According to the app listing, this can increase 2nd page load times by up to 3x, making navigation feel near-instant for shoppers.
How long does setup take — do I need a developer to install it?
No developer is needed. The app listing explicitly states you can 'increase page speed in less than a minute, with our no code install process.' Multiple merchants confirm it is operational in a single click with no technical knowledge required.
Will it work with my existing theme, including custom or OS 2.0 themes?
Yes — the app is described as 'built natively for Shopify, fast & Online Store 2.0 compatible.' Merchants with custom themes have also reported it working without issues, and reviewers describe it as lightweight with no interference to existing store design.
Does it improve mobile speed too, or just desktop?
The app is designed to improve page speed on both mobile and desktop. The listing specifically highlights that it can 'improve page speed on mobile, even on slower connections or older devices,' making it useful for customers browsing on lower-end phones or spotty networks.
What do other merchants say — is it worth installing?
The app holds a 4.7-star rating from 358 reviews on the Shopify App Store, with 88% of ratings being 5 stars. Shopify's aggregated merchant summary states the app 'significantly improves website speed, enhances user experience, and potentially increases sales,' and reviewers call it 'lightweight, free, and efficient.'
What kind of support is available if something goes wrong?
The developer, Booster SEO, offers 24/7 live chat human support. Reviewers consistently praise the support team as fast, friendly, and helpful — with multiple merchants noting quick response times and issues resolved promptly via in-app chat.
