Lack of a clear goal

An advertising campaign shouldn’t start with dashboard settings, but with answering: what do I want to achieve? Video views, purchases, newsletter sign‑ups? “More clients” is too vague. A clear goal helps choose the right keywords, settings, and campaign types.

Irrelevant landing page

The ad promises one thing, but the user lands on something else. For example, they click “Buy LED bulb” and end up on a homepage with dozens of products. This hurts conversions. Create dedicated landing pages for each query or at least adapt content to match expectations.

Too broad reach

Trying to reach “everyone everywhere” is a common mistake. If you don’t use negative keywords or target broad terms like “online courses,” your ads will show to the wrong audience. Costs go up and results go down.

No analytics

Without analytics you’re like a pilot without instruments. You don’t know which ads work, what a lead costs, or where your budget “leaks.” Set up basic conversions: form submissions, button clicks, purchases. This lets you make data‑driven decisions.

Unoptimized ads

Ad copy is your first impression. If it’s generic, templated, or boring, no one will click. Use clear USPs, specifics, numbers—and test variations. Sometimes a single word can change everything.

Insufficient or irrational budget

$5 is too little to test effectiveness, while $500 with no strategy is a costly lottery. Calculate your target cost per action and aim for enough clicks to generate at least 10–20 conversions. That’s the minimum for meaningful analysis.

You set it and forget it

The biggest mistake is not monitoring your campaign after launch. Google might show ads to the wrong people—clicks but no leads. Check daily during the first few days, then weekly. Make adjustments: turn off underperformers and scale what works.
