Global ecommerce is on track to generate around $6.88 trillion in sales during 2026. That’s a rise of around 7.2% compared to the previous year.

While that all sounds amazing, it’s no guarantee that every ecommerce store will automatically find success. That’s because if your website or marketing strategy are falling behind, then so will your sales.

In short, peak season traffic doesn't wait for a site to be ready. If you're planning for Black Friday, Cyber Monday and the Christmas rush, the work needs to start today. 

The Imaginaire team have put together the following pre-peak season checklist for ecommerce businesses.

Our checklist includes all of the key areas that can let your store down, across site performance and digital marketing. So we hope you’ll review each point to ensure you maximise your success in 2026. 

P.S. If you need help understanding what any of the following means, we are here to help! You’ll find our contact info by scrolling to the end of this post. 

Site performance

A site that runs fine on a quiet Tuesday can fall over completely under peak demand. It's worth testing for that reality, rather than making the common mistake of assuming that everything is fine.

You can do so by ensuring there are no development issues lurking under the hood:

  • Run Core Web Vitals tests (LCP, INP, CLS) under simulated peak traffic load, not just an idle-server Lighthouse score
  • Stress-test the checkout and payment flow specifically, since this is the highest-revenue-risk journey on the site
  • Confirm autoscaling and hosting capacity is configured and tested, not just assumed to be sufficient
  • Check the hosting provider's peak-season support tier and SLA
  • Audit and optimise new seasonal creative such as hero banners and campaign imagery before it goes live at scale: compression, next-gen formats and lazy loading all matter here
  • Confirm CDN coverage for all key assets
  • Test the full purchase journey on a mid-range Android device over a real mobile network, not just a flagship phone on wifi
  • Load-test site search and filtering, which is commonly overlooked and commonly breaks first
  • Audit third-party scripts such as review widgets, chat tools and tracking pixels for performance drag
  • Confirm error monitoring and alerting is active so issues are caught in real time during peak

Trustworthiness

Buyers are more cautious during high spend periods. Anything which erodes trust costs conversions fast.

Areas to take care of to build and maintain customer trust:

  • Confirm review widgets are populated, loading fast and not blocking render
  • Check trust signals such as security badges, returns policy and delivery guarantees are visible near the point of purchase, not buried in the footer
  • Audit inventory sync accuracy, since stock status and delivery estimates need to stay reliable under demand spikes
  • Review "was/now" and sale pricing for compliance with reference pricing guidance
  • Re-check SSL certificate validity and renewal dates
  • Confirm contact details, company registration info and returns and refund policy pages are current and easy to find
  • Test any pages affected by a recent migration or replatform for broken trust elements

SEO and content

Seasonal demand starts climbing well before the season itself, so pages need to be live and indexed in advance. Your SEO team should be prioritising the following tasks:

  • Publish or refresh seasonal category and gift-guide content early, before the demand curve starts climbing
  • Run a full technical SEO crawl for broken links, redirect chains, orphaned pages and crawl errors
  • Pull last year's top-converting landing pages and queries to prioritise what to refresh versus rebuild
  • Check indexation status of new or updated seasonal pages well ahead of go-live
  • Review internal linking to surface priority seasonal pages
  • Audit XML sitemaps to confirm they're current and submitted

Marketing and CRM

  • Align paid campaign landing pages with search intent and page speed, to avoid wasting spend on slow or thin pages
  • Audit email and CRM list health and segmentation
  • Test key automated flows including abandoned cart, back-in-stock and welcome series
  • Plan digital PR and link-building activity early, since links built in November rarely help by December
  • Confirm tracking such as GA4, conversion pixels and server-side tagging is firing correctly ahead of the surge
  • Review last year's peak-season campaign performance to inform this year's budget allocation

PPC

Auction pressure and CPCs climb fast in the run-up to Black Friday, so PPC accounts need to be in shape before spend increases.

  • Review last year's peak-season PPC performance, including CPCs, ROAS and top-converting terms, to set realistic budget and bid targets
  • Increase budgets ahead of expected CPC inflation
  • Build or refresh seasonal campaign structure with dedicated sale campaigns, ad groups and promo-specific ad copy, rather than bolting seasonal messaging onto always-on campaigns
  • Update ad copy and extensions with seasonal messaging, countdown or promo extensions and accurate delivery cut-off dates
  • Audit the product feed for Shopping and Performance Max campaigns for accuracy, including pricing, stock status, GTINs and image quality, since feed errors get punished hard during high-competition periods
  • Check negative keyword lists are current to avoid wasted spend as search volume and query variety spike
  • Confirm conversion tracking and attribution are solid before spend increases, since bad data compounds fast at higher budgets
  • Plan bid and budget pacing for key dates such as Black Friday, Cyber Monday and last-order-dates, rather than relying on flat daily budgets
  • Align landing pages for top PPC campaigns with the site performance work above, since a slow landing page undermines paid spend fastest
  • Set up remarketing and retargeting audiences ahead of time to capture browsers from earlier in the season
