Step 1
Find your listings on TripAdvisor, the quickest way is to visit http://www.tripadvisor.co.uk and search for your property name. If you can't find your property, you can add your business - see http://www.tripadvisor.co.uk/BusinessListings for more information.
Step 2
When on your listing page, scroll the the bottom of the page where you will see box titled "Management Resources". Click "Start Here - Visit Your Owners Centre"

Step 3
On this page you want to click "Get this Widget", under "Promote Your Business"

Step 4
A popup box may appear at this stage but you can just close this. After that, change the Preferred size box to Wide - 468px and click "See a Preview"

Step 5
You will then get a pop up box displaying your widget code and a preview. Copy all the text in the box and paste it into your Tripadvisor widget code box under "Recommendations" on your listing control panel.

That's it!
