I only have one campaign and ad so can only show that. I've also already set mine up so your initial experience will be a bit different, but once set up it will work as follows.
This is my landing page. At the top right I've set the date range that the stats should show. I've made it from 11 March since that's when I finally got it to work well.
What isn't obvious is that there is a difference when you click on the campaign title vs click on View campaign. Often when you click on the campaign title or keywords the page load won't complete, e.g.:
Press F5 to reload the page:
You would have been able to set your spend limit when you created the ad but finding that setting again isn't obvious, it's that Edit campaign option above that only displays when you click the campaign title and the page actually loads:
I'm on a limited budget of R1,000 a month. But Google will happily spend 40% more. So I've set my daily to R25/day so that it maxes out to R1,000.
Since my average click cost is R6 trying to include too many countries spreads you exposure to thin. So I've only included South Africa.
I've also excluded the Search Network and Display Network. Then your ad displays on other Google sites or other non Google sites. Once again with a limited budget I feel it is better to only have it displayed on Google searches.
You can set the language but as I'm only focused on SA I've left that out.
You can target "audiences" but I haven't used that.
Below the daily budget is Bidding, I set mine to Maximize clicks. I've also set a maximum of R5/click. Google will spend a bit more anyway.
On the next page you can bulk paste your keywords. You can also do it in another section I'll show shortly. You will want to go to that other section to change the match type, more on that later. You'll notice I don't have single keywords but 2-3 word combos. I think it works better, especially when you set the match type later.
Once done there you'll be back at the All compaigns page, as stated at the top left. If you get lost, and you will, just click the Google Ads link top left:
