I saw these two options on my adsense account it sent me an alert saying optimize your account with these, should I use them and will they help increase my ad revenue?
Focus on your best-performing ads
Only show the ads that make you the most money.
When you only show your best-performing ads, it can lead to a big improvement in the visitor experience of your site, at minimal cost to you. Other potential benefits include:
Faster loading times
More traffic to your site
Users spending longer on your pages
Go to Ad balance to reduce the number of ads you show and see the impact this has on your revenue.
Let Google automatically optimize your account
Using experiments, Google can automatically make improvements to your revenue or user experience on your behalf.
You can let Google run experiments on your traffic and automatically apply improvements to your revenue or user experience. You'll be notified when experiments finish, and you can undo any changes made. If you'd like to review the results of the experiments first, you can choose to apply improvements manually instead.
The experiments that Google carries out on your behalf run on around 10,000 daily impressions per experiment, or on all daily impressions if you have fewer than 10,000. They test about 50% of those impressions on the new settings and the remainder on your original settings for comparison.
