Go to your Seller Central home page.

On the top left click on the menu.

Click on orders.

Click on manage orders.

On the right hand side you will see blue letters that either say "View FBA Orders" or "View Seller Fulfilled Orders". Make sure you are on the screen that's relevant to you. (Are you a merchant fulfilled seller or an FBA seller?)

In the middle of the screen you can filter your orders to be from the last 90 days...365 days...etc.

Filter your orders to show the last 30 days.

You will now see all of your orders placed in the last 30 days.

I recommend you look for all of the orders that were placed between 8-14 days ago from today.

Right click on the blue number next to the order date and open that in a new tab. This is your order number. It looks like this

114-1234567-1234567

Now you will be on the screen where you can see the order details for that specific order. On the right hand side you should find a button that says "request a review". Press that button for that order and follow the prompts. Do this for all of your orders that were placed between 8-14 days ago from today.

Its not a major increase in review generation...but its enough to get you off the ground.
