How do I check my Shopify store speed?

Run your product and collection pages through Google PageSpeed Insights and check the Core Web Vitals report in Google Search Console. Shopify's Online Store speed report also shows trends. Or ask us for a free audit.

What is a good Core Web Vitals score for Shopify?

Google rates a page as good when LCP is 2.5 seconds or less, INP is 200 milliseconds or less, and CLS is 0.1 or less, measured for at least 75% of visits

Do Shopify apps slow down my store?

Many do. Apps that add scripts to the storefront can affect every page. Removing an app doesn't always remove its code, so we check your theme for leftovers.

Will speed optimization change my store's design?

No, unless you want it to. We optimize how your store loads, not how it looks.

How long does Shopify speed optimization take?

[Add your typical range, e.g. "Most projects take X to Y weeks."] Lab scores improve right away; Google's field data updates over about 28 days.

Can you guarantee a 100 PageSpeed score?

No honest agency can. A PageSpeed score is a lab test and changes between runs. We focus on passing Core Web Vitals for real shoppers, which is what affects sales and rankings.

How much does Shopify speed optimization cost?

[Add a starting price or fixed audit fee if you want to show one.] It depends on your theme, apps and number of templates. Start with a free audit and we'll quote the fixes.

How much does a Shopify store cost?

It depends on scope - theme work, custom features, integrations and content. Send the form and we’ll reply with a clear budget range, no obligation.

How long does a build take?

Every estimate includes a launch timeline mapped to your scope, with phased milestones.

Can you migrate my store to Shopify without losing SEO?

Yes. We migrate products, customers and orders, and set up redirects and metadata so rankings carry over.

My store is slow. Can you speed it up?

Usually. We audit your theme, apps and scripts, remove dead weight and optimize images and loading order.

Do you offer support after launch?

Yes - maintenance, new features and conversion optimization.
