1. Bidding too broad, with no proper data

Running broad match keywords without tight audience intent controls (like strong negative keyword lists or custom segments) is a recipe for junk traffic. Broad match can work, but only when paired with real-time search term pruning and data-led audience layering.

2. Landing page doesn't match the search intent

Your ad might promise one thing, but your landing page delivers something else, or delivers it poorly. The most common mistake is having a generic sales funnel, where visitors have to search for the specific relevant offer. Sending traffic to a tailored matching offer or a section built for that specific query is the key.

3. Optimizing for clicks instead of conversions

Overly using Maximize Clicks instead of switching over to Maximize Conversions or Target CPA is another common mistake. Clicks mean nothing if the traffic doesn’t convert properly. Once you have like 10+ conversions in the last 30 days, start feeding the algorithm with real goals, not just vanity metrics.

4. Ignoring conversion tracking quality

Tracking is either broken, missing, or counting fluff (like time on site or scroll depth). Make sure your conversions are "money actions" form submissions, calls, purchases. Use Google Tag Manager, test everything, and set values where it makes sense instead of focusing on generic fluffy data.

5. Letting Google auto-generate everything

Stuff like dynamic headlines, automated assets, auto-applied recommendations, are all good sometimes. But if you’re not regularly reviewing what’s being auto-injected into your ads, you’ll end up with clicks driven by irrelevant or misleading copy, which often bottoms the conversion rate.

6. Not segmenting campaigns properly

The most common mistake is one campaign for everything. Separating search intent from brand, from competitor, from discovery traffic, and segmenting by funnel stages is essential for gathering relevant data, and relevant data is essential for further campaign optimization.

7. Not feeding Google enough data

Performance Max and Smart Bidding can be powerful, but only if you feed them proper data. That means clean data, proper conversion goals, and enough traffic to learn. If your campaign has 2 conversions/week and no audience signals, the algorithm is flying blind and wasting money.

8. Setting & forgetting your ads campaigns

Google Ads have never been about luck, or bad luck. Each campaign needs weekly pruning, ad testing, audience adjustments, and budget shifts.
If your ads aren’t converting, it's never because of bad luck, it’s almost always strategy, structure, or setup, and constant optimization.
