How to Run a Small-Budget Google Ads Campaign

Launch profitable Google Ads on $500-2000/month with conversion tracking, keyword targeting, and ROI measurement.

  1. Set conversion tracking before spending a dollar. Install Google Analytics 4 and Google Ads conversion tracking on your website. Define what counts as a conversion: form submission, phone call, purchase, or appointment booking. Set monetary values for each conversion type. Without tracking, you're burning money blind.
  2. Start with search campaigns only. Skip display, video, and shopping campaigns initially. Launch one search campaign targeting 3-5 high-intent keywords with monthly search volume between 100-1000. Use exact match keywords like "[accounting software for restaurants]" rather than broad match. Write ads that match search intent exactly.
  3. Allocate budget using the 80/20 rule. Set daily budget at 3-4% of monthly budget ($17-27 daily for $500 monthly budget). Bid manually starting at 50-70% of suggested bid amounts. Reserve 20% of budget for testing new keywords and ad copy. Most small budgets get eaten by broad keywords with low conversion rates.
  4. Build tight ad groups with 2-3 keywords each. Group similar keywords together and write 3-4 ads per group. Include your target keyword in headline 1, add price or benefit in headline 2. Write description copy that addresses the searcher's problem directly. Use ad extensions for phone number, location, and site links.
  5. Monitor daily and optimize weekly. Check spend and conversions daily for the first two weeks. Add negative keywords for irrelevant searches that burn budget. Pause keywords with cost-per-click above $10 unless they convert. Increase bids 20-30% on keywords driving conversions below $50 cost-per-acquisition.
  6. Kill campaigns that miss 3:1 ROAS targets. Calculate return on ad spend weekly: revenue from ads divided by ad spend. Profitable campaigns hit 3:1 ROAS minimum within 60 days. Pause any keyword, ad group, or campaign missing this target after spending $200-300. Reallocate budget to winning campaigns and scale what works.
