Multiple Campaigns Competing Against Each Other?

Hey everyone,
I’m running 2–3 campaigns targeting similar keywords (testing different setups), but I’m worried they might be competing against each other internally.
CPC feels slightly inflated since I launched the second campaign.
Is campaign overlap actually a thing in Google Ads, or am I overthinking this?

It can basically make your campaigns compete in the same auctions so the CPC might be a bit fcked up. just consolidate and test inside one campaign (ad groups etc)
 
Yes, campaign overlap can happen in Google Ads. If multiple campaigns target the same keywords or audience, they can compete against each other, which may increase CPC. You might want to use negative keywords or audience exclusions to reduce internal competition.
 
they can compete a little bit, as long as you don't put maximum click withou limit bid, it will be fine
 
Yeah, campaign overlap is definitely real but it’s not always a huge deal. Usually, Google just picks the one with the better ad rank and enters that into the auction, so you're not exactly "bidding against yourself" in a way that doubles the price. But if your CPC is jumping, it might be because you're splitting your data and the algo is getting confused. Better to keep one main campaign and use experiments or ad groups for testing setups, otherwise you’re just making things harder for yourself.
 
You're not crazy, overlap is real, but usually the bigger issue is signal dilution more than literally bidding against yourself on every auction. When 2-3 campaigns share close match types, geo and intent, Google keeps relearning the same pocket from split data and CPC can get messy. I'd normally keep one main campaign and test inside it with ad groups or experiments, then use negatives if you need hard separation. Much easier to read than three similar campaigns fighting for the same search terms.
 
On 1 Google Ads account or on multiple Google Ads accounts, do not target the same geos while targeting similar (or same) keywords for any particular domain. It will trigger a circumventing systems flag.
 
Internal competition not really increase CPC. Google just pick your best Ad Rank for the auction.
But 2-3 campaigns with same keywords will mess up your data and optimization. Better to use one campaign with different ad groups, or use negatives to keep them separate. Otherwise you just waste budget.
 
You're definitely not overthinking it because internal competition is a total buzzkill for your cpc. Just pause the weaker performers or tighten your negative keyword lists so your own ads stop fighting for the spotlight
 
Yeah, campaign overlap can happen in Google Ads. When you target the same keywords in multiple campaigns, they can end up bidding against each other, raising your CPC. Try grouping similar keywords into one campaign, or use negative keywords to prevent overlap. It’ll help lower costs and improve performance.
 
Instead of just grouping keywords, run 2–4 tightly segmented PMax campaigns (e.g., one for new-customer acquisition with first-party exclusions + “new customers only” goal, another for high-margin products). Use the new campaign-level audience exclusions, brand exclusions, and account-level negative keywords to block cannibalization without starving the AI. This keeps the machine focused and often lowers blended CPC while boosting incremental ROAS.The old “one campaign to rule them all” mindset actually creates more hidden overlap today. The winners treat PMax like a precision instrument, not a blunt hammer.
 
yeah, it can happen sometimes and i suggest try not to target the same keywords in different campaigns and their settings because it can make things harder to manage and control.

You're probably not overthinking it. If the campaigns are targeting the same keywords with similar settings, I'd definitely check for overlap.

I've found it's usually better to give each campaign a clear purpose, different match types, locations, audiences, or landing pages. Otherwise, the data gets messy and it's harder to tell what's actually driving the results.
 
yes, this can happen if multiple campaigns are targeting the same keywords and try separating the keywords or settings between campaigns to get better control, good results and avoid overlap.
