What is page speed? (and why shoppers leave slow stores)
Page speed is how quickly your store shows up and becomes usable on a real phone, and the biggest causes of slowness are usually things you control.
The plain meaning
Page speed is how long it takes from tapping your link to seeing a page you can actually use: the product, the price, a button that responds. It is not a score on a website. It is the feeling of waiting.
Picture one shopper
A customer taps your link in an Instagram bio while travelling, on mobile data that comes and goes. The page starts to load. A grey space sits where the photo should be. Nothing happens for a few seconds. She taps back and opens the next account.
That shopper never saw your product. She did not reject it. She just ran out of patience, as most of us do. This is why speed matters even for a tiny store: your visitors are often arriving from social media on a phone, and every second of waiting loses a few of them.
I will not quote how many people leave or how many seconds it takes, because those figures vary and I would only be guessing. The behaviour itself is easy to recognise from your own phone habits.
What makes a store slow
- Large image files. This is the most common cause for small sellers. See what image compression is.
- Too many photos on one page, all loading at once.
- Heavy videos that start automatically. Our post on keeping product videos small for mobile networks helps.
- Too many extra scripts, such as several tracking tools, chat widgets and pop-ups. Each one adds work for the phone.
- A weak signal on the customer's side, which you cannot fix, but can plan for by keeping pages light.
What you can check yourself
- Open your store on your own phone using mobile data, not Wi-Fi.
- Open your homepage, a collection page and a product page.
- Count roughly how long before you can read the product name and price and tap Add to cart.
- Try again on a friend's older or cheaper phone, since that is closer to what many customers use.
If the pictures are the slow part, resize and compress them. Read resizing and compressing product images for web.
Things worth trimming
- Reduce photos per product to what customers truly need. See how many photos each product should have.
- Use a single hero image on the homepage instead of a slideshow of heavy pictures. Our guide to changing the homepage hero image covers the right shape.
- Remove tools you installed once and no longer use.
- Keep your video clips short, and compress them before upload.
How to think about it
Treat page speed as part of respect for your customer. Someone who clicks on your link is giving you a moment of their time, and a quick, simple page honours it. You do not need to chase a perfect score. Fix the obvious things first: large photos, too many extras, heavy videos.
Make a habit of testing your store on your phone once a month, and always after you add new products or change the homepage. Your store grows with every upload, and a few small decisions at upload time keep it light for the people who matter, your customers.
