In its first 10 days (22–31 October 2026), the Google Ads campaign Zero Dimensions runs for Tropical Solar brought 14 buyer actions on the dedicated landing page we built for the company: 8 WhatsApp clicks, 4 enquiry forms at about ₹750 each and 2 call-button clicks (recorded by Google Analytics; Google reported the same 4 enquiry conversions).
The challenge
Tropical Solar designs, supplies and installs solar power plants for factories, warehouses, commercial buildings and open land. Its buyers are plant owners and finance teams planning projects of 100 kW or more.
The brief was business enquiries that could be traced to their source, from a standing start:
- No page to send buyers to. Before October 2026 there was no landing page for Tropical Solar's ads to send business buyers to, so every tracked enquiry had to be won from zero.
- Most solar searches come from households. Searches such as "solar rooftop cost for 3kw" come from home owners, dealers and subsidy seekers. The ads and the page had to speak to business buyers.
- Every action had to be counted. Forms, WhatsApp clicks and calls each needed their own count, so the client could see what each kind of enquiry cost.
What we did
Built a dedicated landing page for Tropical Solar
The landing page went live on 6 October 2026, separate from Tropical Solar's own website. It has sections for industrial roofs, commercial buildings and ground-mounted plants. It sets out the six EPC stages from site survey to maintenance, compares owning a plant with paying per unit, and answers 10 common buyer questions.
Added an enquiry form, WhatsApp and call buttons
Buyers can send an enquiry form, which leads to a thank-you page for Tropical Solar only, kept out of Google's index. They can also tap a WhatsApp or call button.
Tracked every buyer action
Google Analytics records WhatsApp clicks, call-button clicks, form starts and every thank-you page view. In Google Ads we set the thank-you page as the main conversion and added a click-to-call conversion. On each of the 6 days between 22 October and 8 November 2026 with an enquiry form from a paid visit, Google Analytics and Google Ads show the same count.
Launched a Google Ads Search campaign
The campaign started on 22 October 2026 with a ₹300 daily budget and Maximize conversions bidding, targeting businesses across India. It bid on searches such as "solar power installation companies", "commercial solar installation" and "solar epc company", with ads sending people straight to the Tropical Solar page.
Split the campaign by type of buyer
On 2 November 2026 we replaced the first, general solar-installation ad group with three ad groups: factory and warehouse roofs, commercial buildings such as hotels, hospitals and offices, and ground-mounted and megawatt-scale plants. Every new ad says "projects from 100 kW", so home buyers can see the offer is not for them before they click.
Results
In the first 10 days of ads (22–31 October 2026), paid visitors to the Tropical Solar page took 14 buyer actions: 8 WhatsApp clicks, 4 enquiry forms and 2 call-button clicks. Google Ads spent ₹2,999 on 101 clicks, about ₹750 per enquiry form, and Google reported the same 4 conversions. The first enquiry form came on 25 October 2026, 3 days after the ads started.
From 1 to 8 November 2026, the first week of the new campaign structure, paid visitors added 2 enquiry forms, 6 WhatsApp clicks and 2 call-button clicks on ₹2,295 of spend. From 22 October to 8 November 2026 that adds up to 24 buyer actions (6 enquiry forms, 14 WhatsApp clicks and 4 call-button clicks) for ₹5,294, about ₹882 per enquiry form.

What else changed, and what didn't work
- An early result on a new page. The page went live on 6 October 2026 and ads ran for 10 days of October. The campaign was split by buyer type on 2 November, so November's figures come from a new setup.
- Broad searches from the wrong buyers. The broad "solar power installation companies" keyword took ₹2,599 of the ₹5,294 spent (22 October–8 November 2026). It matched home owners, dealership and subsidy seekers, and other solar brands, which is why the campaign was split.
- A small budget. At ₹300 a day the ads showed on about 13% of the searches they could have appeared on: budget cost about 38% of possible impressions and ad rank about 51% (as reported by Google). Google also rated landing-page experience "below average" on several keywords.
- Organic search has not started yet. 4 clicks and 11 impressions in October 2026, and no clicks on 1–8 November (Google Search Console).
Figures checked on 10 November 2026. November 2026 is a partial month.
