SMB Google Ads Case Study: 138 Inquiries at Just $513 Monthly Spend<\/strong><\/p>\n\n\n\n

For small and medium\u2011sized businesses (SMBs), every advertising dollar must work hard. Unlike large enterprises with massive budgets, SMBs need a lean, conversion\u2011focused approach that delivers measurable results without breaking the bank. This case study showcases a real Google Ads campaign for a client whose primary conversion goal is inquiries<\/strong> \u2013 whether via contact forms, phone calls, or live chat. In a single month (June 2026), we generated 138 inquiries with a total ad spend of only $513, achieving an exceptional cost per inquiry of $3.72. Here is exactly how we did it.<\/p>\n\n\n\n

\n\n\n\n

1. Client Background & Campaign Objective<\/strong><\/p>\n\n\n\n

The client is a service\u2011based SMB operating in a competitive local market. They had been running Google Ads on and off but lacked a structured strategy. Their main pain points were: high cost per lead, low conversion rates, and wasted spend on irrelevant clicks.<\/p>\n\n\n\n

The objective was crystal clear: drive high\u2011quality inquiries at the lowest possible cost per acquisition (CPA)<\/strong> , with a monthly budget under $600.<\/p>\n\n\n\n

The campaign data we review here comes from June 1\u201330, 2026, covering all active campaigns within the account.<\/p>\n\n\n\n

\n\n\n\n

2. Account Structure & Targeting Strategy<\/strong><\/p>\n\n\n\n

Given the limited budget, we avoided scattering spend across too many campaign types. Instead, we focused on Search campaigns only<\/strong>, with tightly themed ad groups built around high\u2011intent, commercial keywords.<\/p>\n\n\n\n

Keyword selection:<\/strong> We prioritised long\u2011tail keywords that signal strong purchase or inquiry intent (e.g., \u201cbest [service] near me\u201d, \u201caffordable [service] in [city]\u201d, \u201chow to [solve problem]\u201d). We also added a comprehensive list of negative keywords to filter out irrelevant traffic (e.g., \u201cfree\u201d, \u201cDIY\u201d, \u201cjobs\u201d, \u201csalary\u201d).<\/p>\n\n\n\n

Geographic targeting:<\/strong> We narrowed location targeting to the client\u2019s service area \u2013 a radius of 20 miles around their office. This eliminated spend from users outside the service zone.<\/p>\n\n\n\n

Device & time adjustments:<\/strong> We analysed historical data and found that conversions peaked during business hours (9 AM \u2013 6 PM) on weekdays. We applied +20% bid adjustments for those time slots and reduced bids on weekends and evenings.<\/p>\n\n\n\n

\n\n\n\n

3. Conversion Tracking \u2013 The Game Changer<\/strong><\/p>\n\n\n\n

Many SMBs skip proper conversion tracking, but this is where most savings come from. We set up:<\/p>\n\n\n\n

    \n
  • Google Ads conversion tracking<\/strong> for form submissions (using a thank\u2011you page view)<\/li>\n\n\n\n
  • Call conversions<\/strong> via Google forwarding numbers to track phone inquiries<\/li>\n\n\n\n
  • Import of micro\u2011conversions<\/strong> from Google Analytics 4 (e.g., time on page, button clicks) to feed the bidding algorithm with more signals<\/li>\n<\/ul>\n\n\n\n

    All conversions were assigned a consistent value so that the system could optimise toward inquiries rather than just clicks.<\/p>\n\n\n\n

    \n\n\n\n

    4. Ad Copy & Landing Page Alignment<\/strong><\/p>\n\n\n\n

    We wrote 3\u20134 responsive search ad variants per ad group, each featuring:<\/p>\n\n\n\n

      \n
    • The primary keyword in the headline<\/li>\n\n\n\n
    • A clear call\u2011to\u2011action (e.g., \u201cGet a Free Quote\u201d, \u201cSpeak to an Expert\u201d, \u201cCall Now\u201d)<\/li>\n\n\n\n
    • Benefit\u2011driven descriptions (e.g., \u201cFast Response\u201d, \u201cTrusted by 500+ Clients\u201d)<\/li>\n<\/ul>\n\n\n\n

      Equally important, we ensured the landing page matched the ad promise. The page was simple, mobile\u2011friendly, and contained a prominent inquiry form and a click\u2011to\u2011call button. We also added trust signals (testimonials, badges) to reduce friction.<\/p>\n\n\n\n

      \n\n\n\n

      5. Bidding Strategy \u2013 Maximise Conversions with a Target CPA<\/strong><\/p>\n\n\n\n

      Because the account had some conversion history from previous months, we were able to use Maximise Conversions<\/strong> bidding with an optional Target CPA<\/strong> set at $5.00. This allowed Google\u2019s algorithm to automatically adjust bids in real\u2011time, prioritising users most likely to convert, while keeping the average CPA near the target.<\/p>\n\n\n\n

      We also enabled search impression share<\/strong> reporting to ensure we weren\u2019t missing valuable impressions due to low bids.<\/p>\n\n\n\n

      \n\n\n\n

      6. Results \u2013 June 2026<\/strong><\/p>\n\n\n\n

      Metric<\/th>Value<\/th><\/tr><\/thead>
      Clicks<\/td>558<\/td><\/tr>
      Impressions<\/td>4,420<\/td><\/tr>
      Click\u2011Through Rate (CTR)<\/td>12.6%<\/strong><\/td><\/tr>
      Conversions (Inquiries)<\/td>138<\/td><\/tr>
      Conversion Rate (Clicks to Inquiries)<\/td>24.7%<\/strong><\/td><\/tr>
      Total Ad Spend<\/td>$513<\/td><\/tr>
      Cost Per Inquiry (CPA)<\/strong><\/td>$3.72<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      These numbers demonstrate the power of a well\u2011structured SMB campaign. With just $513, we delivered 138 qualified inquiries \u2013 a remarkable ROI for a small business.<\/p>\n\n\n\n

      \n\n\n\n

      7. Key Optimisation Tactics That Made the Difference<\/strong><\/p>\n\n\n\n

        \n
      • Negative keywords daily review:<\/strong> We regularly added irrelevant search terms to the negative keyword list, preventing waste.<\/li>\n\n\n\n
      • Ad schedule optimisation:<\/strong> We shifted 90% of the budget to weekday daytime hours, when the client\u2019s team was available to respond promptly.<\/li>\n\n\n\n
      • Landing page A\/B testing:<\/strong> We tested two versions of the form \u2013 a short version (3 fields) vs. a longer one \u2013 and the shorter form increased conversion by 15%.<\/li>\n\n\n\n
      • Audience targeting:<\/strong> We added remarketing lists for visitors who had not yet converted, and applied bid adjustments to encourage return visits.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        8. Lessons for Other SMBs<\/strong><\/p>\n\n\n\n

        Start with search, not display.<\/strong> For service\u2011based SMBs, Search ads capture immediate demand \u2013 display can come later when you have more budget.<\/p>\n\n\n\n

        Don\u2019t ignore negative keywords.<\/strong> They are your cheapest way to cut waste.<\/p>\n\n\n\n

        Track every conversion type.<\/strong> Calls, form fills, and even chat interactions should all be counted. The more conversion data you feed Google, the smarter the algorithm becomes.<\/p>\n\n\n\n

        Set realistic CPA targets.<\/strong> For a $500 budget, aiming for a $5 CPA is sustainable. Overly aggressive targets can limit impression volume.<\/p>\n\n\n\n

        Mobile matters.<\/strong> Over 60% of our clicks came from mobile devices, so ensure your landing page is fully responsive and easy to fill out on a phone.<\/p>\n\n\n\n

        \n\n\n\n

        Conclusion<\/strong><\/p>\n\n\n\n

        This case proves that even with a modest monthly budget, an SMB can generate a high volume of inquiries through Google Ads. The secret is not in spending more, but in spending smarter \u2013 using precise targeting, rigorous conversion tracking, and continuous optimisation.<\/p>\n\n\n\n

        If your business relies on inquiries to grow, adopt the same disciplined approach. With $513, we achieved 138 conversions \u2013 and with further scaling, the potential is even greater.<\/p>\n\n\n\n
