Hi @Sam0507, sorry to hear about this, must be very annoying. 
Ads are usually coming from either a downloaded application or from visiting a website.
Have you tried restarting your device in safe mode? That is an easy way to see if this is caused by a downloaded application as they will be temporarily disabled in this mode.
If it is the same behaviour in safe mode, try clearing data for the Chrome application in your device. Do note that this will delete downloaded files from Chrome and locally stored data, such as bookmarks.
To do that, go to Settings > Apps & notifications > App info > Chrome > Storage > Manage Space > Clear all data.
Let me know if that helps!

Thanks for your help.
Hi again and I'm glad to hear that you rid of the ads! 
Let me know if there is anything else I may assist you with and have a nice day!
What to do if advertisements keep on popping up? This happens randomly, regardless if I'm doing something on my phone or I'm just on stand by but phone screen is unlocked.
