ChatGPT Advertising: How It Works, What It Costs, and Whether You Should Be There Yet

Retail Advertising Case Study: Evaluating ChatGPT Ads Against Paid Search

Client: Confidential Retail Brand - USA

Problem:

The retail business was already investing in paid search and wanted to evaluate ChatGPT advertising as an additional customer acquisition channel. The main challenge was understanding whether the emerging advertising platform could generate conversions at a competitive cost without diverting too much budget from established campaigns.

Our Solution:

W3era developed a proposed 90-day testing framework to evaluate ChatGPT advertising alongside the retailer’s existing paid search activity. The plan allocated a test budget equivalent to 7.5% of the quarterly paid search budget, with campaign performance assessed through clicks, conversion rate, cost per conversion, and conversion quality.
The approach focused on establishing a reliable baseline, validating tracking, reviewing campaign performance, and identifying whether the channel warranted further investment.

Outcome:

The proposed test uses a $9,000 ChatGPT Ads budget and a $120,000 paid search comparison budget. The supplied illustrative figures indicate the following potential results:

• 7,500 clicks from the ChatGPT Ads test.
• 150 conversions, with an illustrative 2% conversion rate.
• $60 cost per conversion, based on the proposed test budget.
• $115.38 cost per conversion for paid search, based on the comparison figures.

These figures suggest a potential acquisition-cost opportunity, but they have not been verified against a real campaign. The test framework is designed to help the business assess conversion quality, compare channel performance, and determine whether additional investment is justified.

ChatGPT Advertising Case Study: Generating Qualified IT Service Enquiries Through Paid Campaigns

Client: Confidential IT Services Company — USA

Problem:

The client, an IT services company offering technology solutions to businesses, wanted to generate more qualified enquiries for its software development, IT consulting, and custom technology services. The company needed to reach relevant business decision-makers and encourage them to request consultations about their project requirements.

Its main challenge was to explore ChatGPT advertising as an additional lead-generation channel while maintaining control over advertising costs and measuring the business value of the enquiries generated.

The company wanted a structured campaign that could help it evaluate traffic quality, consultation requests, and the cost of attracting potential clients before committing to a larger advertising investment.

Our Solution:

W3era developed a focused ChatGPT advertising campaign designed to promote the client's IT services and generate consultation enquiries from businesses seeking technology solutions.

The campaign strategy included:

• Campaign planning: Align campaign messaging with the company's IT services, target markets, and business objectives.
• Ad copy development: Highlight service benefits, technical capabilities, and business challenges that potential clients may want to solve.
• Landing page alignment: Direct interested visitors to relevant IT service pages with clear consultation and project enquiry options.
• Budget management: Monitor advertising expenditure and campaign engagement to keep spending aligned with the agreed budget.
• Conversion tracking: Measure clicks, consultation requests, conversion rate, and cost per enquiry to evaluate campaign performance.

Outcome:

The following campaign figures illustrate the proposed performance scenario. They should be replaced with verified results before being presented as actual client outcomes.

The proposed campaign generates 1,500 clicks from a $2,400 advertising budget at an assumed average cost per click of $1.60. At a 4% landing page conversion rate, those clicks produce 60 IT service enquiries, resulting in an estimated cost of $40 per enquiry.
