Black Friday (Efsane Cuma) is approaching, and this year the calendar is tight. Businesses that leave their Black Friday 2026 preparation to the final week often end up facing stock shortages, a site that slows down under heavy traffic and ads that don't perform at full efficiency. In this guide, we walk you step by step through how to make the most of the four weeks left until November 27.
By the end of this post, you'll have a checklist you can tick off item by item across the campaign calendar, stock, site speed, ads and communication. We'll also cover how the latest change to the installment regulation should be reflected in your campaign messaging.
When is Black Friday 2026? Key dates
According to a report by Yeni Asır, Efsane Cuma falls on Friday, November 27 in 2026. However, the November sales season isn't just a single day. According to Pixa Software's 2026 e-commerce campaign calendar, the key dates are:
- November 1-10: Pre-Black Friday early access period
- November 11: 11.11 Singles' Day
- November 23-27: Efsane Cuma / Black Friday week
- November 30: Cyber Monday
This timeline shows that you don't really have four weeks to prepare, but only a few days. Since the early access period starts on November 1, you need to finalize your ad, stock and campaign decisions this week.
This week's to-dos: lock in your campaign calendar
The first task is deciding which offer you'll run in which period. Repeating the same discount in every period trains customers to wait and weakens the impact of the main week. That's why it's healthier to give each date its own role.
- Separate the periods: You might consider a setup like an exclusive perk for your email list or loyal customers during early access, a one-day surprise on 11.11, the main campaign on November 23-27 and a last-chance message on November 30.
- Calculate your margin: When setting your discount rate, factor in shipping, marketplace commission, payment processing fees and ad costs. A discount that looks attractive on paper can lose you money once these costs are added.
- Put the rules in writing: Gather the campaign start and end times, coupon codes, minimum cart value and return conditions in a single document. Make sure everyone on your team is working from the same information.
- Be transparent about pricing: Making sure the pre-discount price you display is genuine and consistent matters for both customer trust and legal compliance. Avoid raising prices just for the campaign and then showing a discount.
Stock and operations checklist
No matter how good your campaign is, your effort goes to waste when products sell out or shipments are delayed. Securing the operations side now prevents panic on the busiest days.
- Identify your best-selling products and get written confirmation of delivery times from your suppliers.
- Test inventory sync (automatic matching of stock levels across all channels) between your website and marketplaces; selling an out-of-stock product means cancellations and negative reviews.
- Talk to your shipping carrier about peak-season capacity, daily pickup times and possible delay scenarios.
- Take care of small but critical items like packaging materials and invoicing infrastructure in advance.
- Create ready-made response templates for customer service covering shipping, return and coupon questions.
Test your site speed and payment infrastructure
During campaign days, your site gets far more visitors than usual. Site speed, meaning how long your pages take to load, directly affects sales during this period; a slow-loading product page can send visitors straight to a competitor.
Speed and server
- Compress product images and remove unused plugins.
- Talk to your hosting provider about your capacity during high-traffic periods.
- If you're not using a CDN (a content delivery network that serves files from the server closest to the user), consider one.
- Don't make major design or infrastructure changes to your site during campaign week; finish all changes by mid-November.
Cart and checkout
- Place a real end-to-end test order on both mobile and desktop.
- Check that coupon codes work correctly and discounts are applied correctly in the cart.
- Verify that installment options display correctly with cards from different banks.
Tracking
Make sure your ad pixels and conversion tracking (recording target actions such as purchases) are working. Without tracking, you won't be able to tell which channel made you money after the campaign.
Ad prep: warm up your campaigns now
Ad platforms spend some time collecting data to understand a new campaign and find the best audience; this is called the learning phase. Instead of launching ads from scratch on the main campaign day, going live a few weeks early helps this phase wrap up before the busy days.
- Grow your audiences: Visitors who arrive during the early access period form your retargeting audience (showing ads again to people who have visited your site) for Black Friday week.
- Multiply your creatives: Instead of showing the same visual for weeks, prepare different images and videos for each period.
- Split your budget by period: Plan separate budgets for early access, 11.11, the main week and Cyber Monday.
- Keep your product catalog up to date: Make sure the price and stock information in the product feed used for shopping ads matches your site exactly.
- Automate your scheduling: Set campaign start and end times in advance instead of relying on manual changes at midnight.

How does the installment regulation affect campaign messaging?
According to the Ministry of Trade's announcement, new regulations for retail installment sales aligned with the decisions of the BDDK (Banking Regulation and Supervision Agency) took effect on October 15, 2026. According to the same announcement, the installment limit for new mobile phone sales was raised from TRY 20,000 to TRY 40,000. A 12-month term limit applies to phones priced at TRY 40,000 or less, and a 3-month limit applies to those priced above that amount.
If you sell phones or products sold on installment, review your campaign copy against these rules:
- Instead of using a generic "12 installments" promise in banners and ad copy, clearly state which products the installments apply to.
- Check that the installment tables on your product pages comply with the current rules.
- Confirm your installment settings with your payment provider.
- Verify the rules that apply to other product categories with the Ministry's announcement and your bank; don't use any installment promise in your ads that you're not sure about.
Prepare your content and communication plan
Planning in advance what you'll share on which channel to promote your campaign eliminates last-minute scrambling. Social media posts, email and SMS copy, product page descriptions and banners should all deliver the same message.
- Set up a short sign-up or notification campaign for early access and collect interested customers into a list.
- Prepare countdown content, featured product showcases and posts explaining the campaign rules for social media.
- Send emails and SMS only to your opted-in list, and schedule send times in advance.
- Update shipping and return conditions on your FAQ page.
💡 Tip: Gather all campaign visuals, copy and send times in a single calendar file. Seeing which content goes live on which day, at what time and on which channel greatly reduces confusion within the team.
Final-week and post-campaign checks
As you head into Black Friday week, focus on checking your existing preparation rather than starting new tasks. And when the campaign ends, the work isn't over; the data and customers you gather during this period are valuable for the months ahead.
- On the morning of the campaign, do a final check of prices, coupons and stock information.
- Monitor ad spend and sales at regular intervals throughout the day; pause underperforming ads.
- After the campaign, note which products, channels and messages worked.
- Send first-time customers a thank-you message and a small incentive for their next purchase.
- Wrap up the campaign in a controlled way with Cyber Monday and prepare your transition plan for the holiday season.
