Thanks for responding! Why did they create both? Is keyword level better than adword level or is it personal preference?
One isn't better than the other - it's just a question of flexibility. In most cases you want to match the keywords in an adgroup to the ads for that group and the landing page for that ad, but occasionally you may want to send a searcher for a very specific keyword to a different landing page for a specific promotion.
The Destination URL is the URL of the web page that is displayed when an ad is clicked. The Display URL is the URL that is displayed in the ad itself.
The Destination URL is the URL of the web page that is displayed when an ad is clicked as in we can say your domain name but The Display URL is the URL that is displayed in the ad itself like we can say subdomain like first the main url which we can see the site url on which your ad was posted than your ad url for example: your webpage url is example.com it's your destination url & on display url like first site name/example.com !
