Installing an app for everything
This is the most common mistake. Every app adds a monthly fee, another piece that can break and, in many cases, scripts that load on every page and slow the store down. Many features solved with apps can be done natively or with a few lines in the theme: content blocks with metafields, filters with Search & Discovery, bundles with Shopify Bundles, automations with Shopify Flow or abandoned cart emails with Shopify Messaging.
Before installing an app, ask yourself whether you need it on launch day and whether a native alternative exists. And if you uninstall one, check that it has not left code behind in the theme.
A typical case: installing a reviews app, a pop-up app, an upsell app, a translation app and a chat app all at once, before the first sale. Start with the minimum, measure and add only when you have a concrete reason.
Structuring the catalog poorly
A catalog that is badly planned at the start is expensive to fix later. The typical failures are creating separate products for what should be variants, using tags as a catch-all, putting technical data inside the description instead of in metafields, or not thinking about the filters customers will use.
Remember that Shopify allows up to 3 options per product. If your product has more dimensions (for example size, color, material and engraving), decide before uploading anything what will be a variant, what will be a metafield and what will be a personalization option.
Unclear shipping, returns and policies
Many carts are abandoned when the customer discovers an unexpected shipping cost at checkout. Set up simple zones and rates, communicate your free shipping threshold if you have one and show approximate delivery times on the product page and in the cart. The same goes for returns: a clear, easy-to-find policy builds trust.
Legal pages (legal notice, privacy, terms of sale, cookies) should be reviewed with an advisor. The generic templates any tool generates are a starting point, not final copy.
Launching without redirects or basic SEO
If you are coming from another platform, not setting up 301 redirects is the fastest way to lose the organic traffic that took so much effort to earn. Every old URL with visits or backlinks should point to its equivalent on Shopify. You can create them under Content > Menus > View URL redirects, one by one or in bulk by importing a CSV.
Even if the store is new, review the titles and meta descriptions of your main collections and products, the image alt text and that the final domain is set as primary. Then submit the sitemap in Search Console.
Neglecting the product page and mobile
Most visits come from mobile, yet many stores are designed and reviewed on desktop. Check every template on a real phone: button size, order of information, image load speed and whether the buy button stays within reach.
On the product page, the usual failures are too few photos, descriptions copied from the supplier, hidden shipping information and variants that are hard to select. This is the page where the purchase is decided; it deserves more time than the home page.
It is also common to forget the cart and error pages: an empty cart with no links back to collections or a 404 page without search makes customers leave instead of continuing to shop.
Not measuring from day one
Launching without analytics set up leaves you blind in exactly the weeks when you learn the most. Review the Shopify reports, connect Google Analytics 4 and the pixels for the platforms where you will advertise through the official integrations or custom pixels, and confirm with a test order that the purchase event is recorded.
Also define what you will look at each week: sessions, conversion rate, average order value and where sales come from. Without that, every later decision is guesswork.
And do not forget cookie consent: in Spain you need a banner that blocks non-essential cookies until the user accepts. Shopify includes its customer privacy tool, but the copy and the specific setup should be reviewed with your advisor.
Pre-launch checklist
Before removing the store password, go through these points. They will spare you most of the surprises of the first week.
- Test orders with every payment method and shipping zone
- Confirmation and shipping emails reviewed with your branding
- 301 redirects uploaded and tested
- Legal policies reviewed by your advisor
- Analytics and pixels recording purchases
- Full review on mobile
- Unnecessary apps uninstalled
Frequently asked questions
How many apps should a Shopify store have at launch?
There is no right number, but there is a rule: only the ones that solve something you cannot do natively or with the theme. Every app should justify its cost and its impact on speed.
Can I fix the catalog after launch?
Yes, but it costs more: turning products into variants or reorganizing collections can change URLs and forces you to create redirects. It is worth spending time on it beforehand.
Do I need to set up any SEO if the store is new?
Yes, the basics: titles and descriptions for the main pages, alt text, the correct primary domain and a sitemap submitted to Search Console.
What should I do if I spot a mistake after the store is live?
Duplicate the theme, fix it on the copy and publish it once it has been tested. That way you do not break the live store while you fix the problem.
