Common questions

Everything you need to know

What does Server-Side mean for Shopify collection pages?

Tagalys Server-Side means your collection pages are built and delivered complete on the very first load, directly through Shopify's rendering pipeline. Every product, price, sort order, and pin is already in place when the page opens. There is no separate render step where products appear after the page has loaded. Search engines receive full HTML from the first request. Shoppers see a complete grid immediately. Because the page is delivered through Shopify's own infrastructure, uptime is tied to Shopify's 99.9%, not a third-party service.

How is Server-Side different from the JavaScript integration?

Tagalys supports both Server-Side and JavaScript integrations and they are not mutually exclusive. JavaScript works well for search and recommendations. Server-Side is the more reliable path for collection pages specifically, because it removes the additional render layer between Shopify and your shopper. It is also faster to get live. Most stores are up and running within 48 hours because it works through Shopify's native rendering pipeline with minimal front-end changes.

How quickly do stock and price changes reflect on collection pages?

Almost immediately after you save in Shopify. This matters most during sales and for size-sensitive categories, where stale data on a collection page leads to wrong add-to-carts, failed checkouts, and support tickets. With Server-Side, your collection pages stay accurate in near real-time because they read directly from Shopify's data rather than waiting for a separate sync.

What happens to collection pages during a traffic spike like BFCM?

They stay live and fully loaded. Server-Side collections are delivered through Shopify's infrastructure directly, so there is no separate render layer that can slow down or fail when traffic surges. Your uptime is tied to Shopify's own 99.9% reliability. There is no additional service between your collections and your shoppers that could become a point of failure during your highest-traffic moments.

Will Server-Side improve my store's SEO?

Yes. Search engines index the HTML they receive on the first request. With JavaScript rendering, there is a risk that a crawler sees an empty or partially populated grid before products load in. With Server-Side, the full product list is in the HTML from the first request, so new arrivals, price changes, and collection updates are discovered and indexed more consistently and more quickly.

Do I lose any Tagalys merchandising features if I use Server-Side?

No. Every Tagalys feature including smart sorting, pinning, Segments, Markets, Looks, and Sequences works fully with Server-Side. You get everything the JavaScript integration offers, plus the performance, reliability, and SEO benefits of server-rendered collection pages.

Can I use Server-Side for collections and JavaScript for other parts of my store?

Yes. Many brands run Server-Side for collection pages and JavaScript for site search and recommendations. The two integrations are designed to work alongside each other. Tagalys can help you decide the right setup for your store during onboarding.
