The level or benchmark you are aiming to achieve for your KPIs, e.g. blood pressure of 120, cholesterol levels under 200 (mg/dL), or a body mass index between 18.5 and 25. A business gets a lot of things achieved through its ads. A digital branding company is what helps make this happen. They help businesses make their ad spend budgets better and allocate their funds easily.
This can only be done if the initial thought of the business is cleared. That is, what needs to be achieved by the business? Sales, leads or brand awareness. This helps align PPC goals with the overall marketing objective, thus making a plan that stands out.
It is then an agency’s job to help you turn these goals into measurable performance metrics that you can invest in and give you some form of return.
The next step that any branding agency India will guide you through when taking the initial steps of setting up ads is to find the ideal customer persona (ICP). This is because not everything works for everyone, and thus, ads need to be made based on what caters to your audience and not just what looks good.
Alongside this, another important step is choosing the correct platform for ads based on your type of audience. For this, one has to study the behaviour patterns of their ICP and then choose a platform that they use most (Google Ads, Meta, LinkedIn etc)
For example, An agency will understand that if your audience is of the traditional roots, a campaign with regional languages and insights will work far better than anything else.
Budget = (Target Conversions x Cost Per Conversion)
It is important to determine your Cost-Per-Click (CPC). The easiest way to do that is to divide the total cost of your ad campaign by the total number of clicks. Then you need to calculate your conversion rate, for that, divide the number of conversions by the total number of clicks, and then multiply by 100 to express it as a percentage. It is that simple.
Formula: CPC = Total Cost of Clicks / Total Number of Clicks
CPC helps you understand the cost of each click on your ads, allowing you to assess the efficiency of your advertising spend and make informed decisions to optimize your campaigns.
Formula: Conversion Rate = (Number of Conversions / Total Number of Clicks) * 100
Conversion rate measures the percentage of clicks that result in a desired action, helping you understand how effective your ads are at driving conversions.
Together, they set the correct format for your final budget allocation
The key to a successful campaign is to use the budget smartly. A branding agency India will try to divide your budget in proportions that change the ultimate return of these investments, and understanding that becomes important.
They will also study your metrics to see what works, what doesn’t and depending on that the next campaigns will start.
Start with A/B testing.
Then find what works and once you get that, leverage it with trends and regional changes to keep making the most out of a campaign that works. Try and revive the campaign for festive seasons or product launches and make the most out of the investment being made. Keep a track of current trends or allow your agency to do that so that you can use them to make your campaign more and more successful.
Collaborating with a professional branding agency can change the way your brand is presented to a new audience, as they will strive to make your ads a success and identify the exact people to whom your ads should speak to. A good ad is not just pretty, it is strategic both in its format and who it caters to, and that becomes necessary to make a successful ad campaign that gives an ROI like never before.
To calculate your PPC budget for 2025, start with a clear understanding of your business goals—whether it’s driving revenue, generating leads, or growing awareness. Then work backwards using estimated cost per click (CPC) and conversion rate data.
Here’s a simplified formula: Monthly Budget = (Target Conversions ÷ Conversion Rate) × Estimated CPC
For startups or ecommerce brands, CPC forecasting is especially crucial. You can use historical campaign data, industry benchmarks, or forecasting tools like Google Ads' Performance Planner. At Confetti, we help brands map out realistic media budgets using a blend of first-party data, competitor benchmarks, and growth targets.
A general ad spend vs revenue ratio falls between 5%–15%, depending on your industry, growth stage, and profit margins. Startups in aggressive growth mode may spend closer to 20%, while mature brands often hover around 7–10%.
For ecommerce businesses planning their PPC budget in 2025, it’s wise to align media spend with expected customer lifetime value (LTV) and acquisition cost (CAC) targets. Confetti often recommends tying budgets to ROAS goals—not just percentages—so brands optimize for outcomes, not just spend.
