About Plug in Speed

Speed Up Your Shop & Increase Conversions

Did you know?

Google considers overall website speed & page speed as SEO ranking factors while ranking your Shopify store in search results.

This means, if your shop doesn’t load fast, it will slide down in the SEO rankings, giving your competitors an opportunity to outrank you, leading to more visibility, traffic, conversions, & revenue.

The bottom line is - Speed matters, and it can make or break the success of your shop sales.

The good news is - Plug in Speed helps you handle this on autopilot.

Install it today, improve page load speed of your store, & start seeing more orders pouring in.

Image Compression Without Compromising On Quality

You want your product images to look great on your shop. Google wants your shop to be fast and your images to be massively compressed to give you a good score on speed.

But the problem is that highly compressed JPG have a lot of noise and PNG just doesn’t compress well.
