Frequently Asked Questions (FAQ)
How much does a Google Ads campaign cost?
It depends on the industry. In Montenegro and the region, CPC can range from 0.10 to 2 euros, and in competitive sectors even higher. The monthly budget for smaller businesses usually starts from 300-500 euros, while larger campaigns may require 2,000+ euros monthly. The key is that the cost per conversion is lower than the value that conversion brings you.
Is Google Ads good for small businesses?
Yes — especially for:
- local services
- emergency services
- salons, restaurants, hotels
- e-commerce
Small businesses have the advantage of being able to precisely target the local market with a smaller budget and achieve excellent return on investment (ROI).
When can I expect results?
Usually within the first 2-7 days after launching the campaign. However, for true optimization and stable results, 4-8 weeks of testing and adjustment is needed. First conversions can come very quickly, but it's important to be patient while the algorithm learns who your best users are.
What are negative keywords and why are they important?
Negative keywords are terms for which you don't want your ad to appear. For example, if you sell premium services, add "free," "cheap," or "tutorial" as negative words. Without them, you pay for clicks from users who have no intention of buying — which wastes budget without results. Regularly updating the negative keyword list can reduce campaign costs by 20-30%.
What's the difference between Google Ads and SEO?
Google Ads delivers immediate results with payment per click, while SEO builds free organic traffic long-term. Google Ads is ideal for quickly testing the market, launching new products, or seasonal promotions. SEO takes 3-6 months to show results, but once positions stabilize, traffic comes without additional costs. The best approach is combining both channels — Ads for short-term results, SEO for long-term strategy.
How to improve an ad's Quality Score?
Quality Score is improved by optimizing three factors: ad relevance, expected CTR, and landing page quality. Specifically: use keywords from the ad group in the headline and description, create a landing page that directly answers the promise in the ad, and test multiple ad variations to find those with the best CTR. A higher Quality Score means lower CPC and better ad position.
Conclusion
Google Ads can become your most profitable marketing channel — but only if you have a clear strategy, properly set campaigns, and continuous optimization.
