Website speed: what really affects rankings
Speed is a ranking factor, though a minor one. What matters far more is that a slow website loses buyers before they even see anything.

Reality
How speed makes a difference
On rankings – indirectly. A very slow website loses out when everything else is equal, yet a fast website with poor content will never reach the top.
On conversion – directly. Every second of delay reduces the number of orders. You can see it in the analytics of any store.
On indexing – too. The crawler visits fewer pages when the server responds slowly.
Causes
What slows a store down most often
🖼
Heavy images
The most common cause. Photos of several megabytes in product pages and banners.
📜
Unnecessary scripts
Chats, counters, widgets – each one adds delay.
🖥
Weak hosting
The server takes a long time to respond, and no front-end optimization can make up for it.
Order
Where to start optimizing
Measure a product page on mobile. Skip the home page on desktop. The product page is what decides whether an order happens.
Compress images. The cheapest step with the biggest effect in most stores.
Remove unneeded widgets. Audit what you have installed and see what you actually use.
