Recently, I've been studying about and testing Pay Per Click ads, and I'm beginning to realize how little errors may have a big impact on outcomes.

One thing I've observed is that inadequate testing of landing pages can result in significant financial waste.

I would want to hear what others have to say:

When you initially started using PPC, what was the one error that lost you money?

Learning from actual experiences and avoiding typical mistakes would be fantastic.
 
Broad match with no negatives, that one bled money stupid fast.
You think you’re buying buyer traffic, then half the spend goes to junk searches and curiosity clicks.
Now I lock search terms daily for the first week before scaling anything.
 
Sent paid traffic to bad landing page and burned budget fast. No split test and no tracking so i didnt know what worked.

Fix tracking first then test small.
 
Running broad match with zero negative keywords lol. Burned through the budget in 3 days and got mostly junk traffic. Learned the hard way to always start with exact or phrase match and build negatives from day one. That one mistake cost me more than it should have.
 
My biggest early mistake was definitely trusting Google's default 'Search Network' and 'Display Expansion' settings for a standard search campaign. It completely drained my daily budget on low-quality mobile app clicks and garbage placements before I even realized I had to manually opt out of them.
 
not checking search terms for like 2 weeks straight on a new campaign. came back to find half the budget went to completely irrelevant queries. now i check search terms daily for at least the first 10 days, no exceptions. also trusting google's recommended settings on campaign creation is a trap, they enable search partners and display expansion by default and it just eats your money
 
not adding negative keywords from day one. i was running ads for "web design services" and getting clicks from people searching "free web design templates". burned through like $300 before i noticed
 
landing page testing is actually not the biggest money pit imo, broad match keywords with no negative list will drain your budget way faster. i ran google ads for a supplement offer years back and blew through $800 in like 4 days because i forgot to add any negatives, google just matched me to every loosely related search term imaginable and my CTR looked great but conversions were zero. the landing page was fine the whole time, it was the traffic quality that destroyed the campaign.
 
I tried to link a Google Merchant Center account to my Google Ads account, then listed some products that were rejected, and ended up getting banned from both Merchant Center and Google Ads.
 
For many, the biggest early mistake was not tracking properly—running ads without clear conversion data or relying only on clicks. Without accurate tracking, it’s easy to scale the wrong campaigns and waste budget.
 
I did many mistakes, but the one that cost me the most was....having my ads turned on by mistake while I was switching payment processor for my website, so in the end customers couldn't pay. Lost 4k in 3 days until I realised, that was so stupid.
 
For gambling ads on google one big mistake is to do broad match keywords. It doesn't bring good traffic at all.
 
One of my biggest mistakes was trusting early results too quickly. I saw a few conversions, ensure the campaign was working and increased the budget fast but, it turned out those were just conversions and performance dropped after scaling.

Broad keyword matching without a solid negative keyword list is usually what burns through budgets the fastest when you're starting out. We've seen campaigns bleed money because they were bidding on high-intent terms but showing up for completely irrelevant window shopper searches that never had a chance of converting.
 
Sending paid traffic to a bad offer and trying to “optimize” ads instead of fixing it.
Burned budget tweaking bids/keywords when the page just didn’t convert.
Now I validate offer first (cheap traffic or tests) before scaling anything.
