Talk to your suppliers, get discounts for big volumes
Negotiate your delivery time and cost with your shipping company - they will be very busy during those days
#2 Then adjust the commercial offer
Prepare your offer early: products, discounts, stocks
Promote the highly marketable products
Set real discounts for products
Focus on some “star” product categories!
#3 Manage your website
Optimize your site, test it for high traffic volume and a 10-20x number of orders
Talk to your hosting company
Prepare a special Black Friday Landing page (use several black hues, sale percentages, a countdown)
Make sure you have available staff for live customer support, from Thursday to Sunday, 24/7
#4 How to promote your site
Start communicating to your public early. On your website, through your newsletter, social media, display banners and other marketing channels
Inform your public early and as detailed as possible about the discounted product categories. When you send users to a landing page, they should already be filtered, not all products on one page (e.g. dresses, shoes, boots, sofas, etc.)
Black Friday is on a Friday :). You should start your teasing campaign on the Monday right before it:
Add a Black Friday Sale branding skin to your website
Send out a newsletter
Post about on Facebook
Set up some Google Display campaigns
Organize a small contest and tell your users about it
Don’t forget to advertise your star product categories
#5 Manage your affiliate program
Communicate with your affiliates
Fuel up your account. If you don’t spend the money, you can always withdraw it.
Process and pay those commissions fast
Keep your affiliates close, communicate with them, always be online
Prepare special Black Friday feeds, banners and landing pages.
Pick the advertisers you want to promote on Black Friday, considering a high conversion rate, a high approval rate, fast payments (check the pre-paid programs, we have plenty!), as well as their responsiveness and flexibility
First talk directly with those you constantly work with, but pick others too and ask them early about their Black Friday plans - when they have it (day and time), what tools they are offering, if they are focusing on a certain product category.
Focus on a few niches that you already have knowledge about, you can make a lot of money.
As about stocks, plans and promotions
Have another look at the TOS of the advertisers you are working with.
Pick the big brands, but also check the rest of the available programs. You can find real gems with low competition and high ROI.
Be online starting Thursday afternoon until Friday evening, at least. There will be a lot of opportunities, but also a few traffic or hosting issues you will have to take care of real quick so you can maximise your results.
Read a few success stories from the past to motivate and inspire you.
Start sending higher and more targeted traffic a week before the event. You will have time to optimize better for the Black Friday weekend.
