Does investing more in Google Ads increase sales? When does it make sense to increase the budget

There is a dangerous belief in the digital marketingIf I want to sell twice as much, I only have to invest twice as much. However, the reality is that the investment/sales relationship is rarely linear, The market becomes saturated, the CPC skyrockets and profitability plummets.

Before touching the budget lever, it's important to understand whether your investment is part of a well-defined strategy or are you simply trying to scale up without a base?. In many cases, working a campaign correctly from the outset within a service Google Ads Professional makes the difference between scaling profitably or losing money.

The investment/sales ratio is not proportionate

Experience shows that every account has a «glass ceiling». Increasing investment without a solid strategy behind it often leads to buying lower quality traffic. simply to meet daily expenses.

Before expanding, we must analyze whether we are facing a real opportunity The company is faced with an already saturated market where each new euro invested returns less than the previous one (known as decreasing marginal ROAS).

First, let's start with a good foundation:

Before considering a substantial increase in investment in a new plant, it is necessary to Google Ads account, In order to ensure that these three pillars are perfectly optimized, it is essential that these three pillars are perfectly optimized:

Optimization of the Google Ads account.

  • Coherent campaign structure: Campaign segmentation must make sense according to our client's business and product type. On the other hand, the campaigns must have sufficient data volume so that the algorithms of smart bidding The catalog must be sufficiently segmented to be able to analyze data and make precise strategic decisions about specific brands, product types, etc.
  • Budget distribution: the overall budget of the account must be correctly distributed among the different campaigns according to the results of conversions, conversion value and profitability. This is critical if they are also limited by budget.
  • Investment leakage: the Google Ads account must be properly optimized so that there are no significant investment leaks such as: irrelevant search terms and/or with exorbitant CPCs, geographic locations that we do not work with, site exclusions, applications, etc.
  • Branding channeling: it is very important to make sure that branded traffic is limited and does not artificially «inflate» the results of the rest of the campaigns.

Your online store as a conversion machine

It makes no sense to try to scale the sales of a business if we do not have a fast, modern and usable website. In Google Ads, you pay for each click; if the website does not convert, you are paying for «bouncing» users. To scale, it is essential:

  • Speed and UX (User Experience): A slow or confusing website is the biggest enemy of ROAS. According to Google data, a delay of seconds in mobile loading can cause conversions to drop by 20%. The mobile version must be flawlessThe user will be able to access all the information in the shopping cart: accessible touch buttons, legible fonts and a visual hierarchy that guides the user to the cart without distractions.
  • Frictionless funnel: The checkout process is where battles are won or lost. An eternal checkout kills impulse sales. It is vital to integrate a fast payment gateway (such as Google Pay, Apple Pay or Bizum) that allows you to buy in two clicks. In addition, the funnel must be free of technical errors or unnecessary steps that force the user to think twice.
  • Clear value proposition: If you're going to invest more to attract more people, your product must be «eye-catching». You need product cards with persuasive descriptions, high quality images and visible trust factors (customer reviews, security seals, clear return policy). 

The pillars of the business model

Investing in advertising is putting a giant spotlight on your company. If the business model has cracks, the investment will make them more visible.

  • Attractive and competitive product: In a constant comparison environment like Google Shopping, your product must stand out. If your price or shipping costs are not competitive, no matter how much traffic you bring, the user will end up buying in the next tab.
  • Internal and external logistics: Scaling in Google Ads means receiving more orders. Is your warehouse ready to process twice as many orders without errors? Logistics must be fast and efficient. A late delivery today is a customer not coming back tomorrow (and a possible negative review).
  • : Marketing does not end at the click, not even at the sale. A quick pre-sales support (via chat or WhatsApp) can save an abandoned cart. And impeccable after-sales support is what turns a one-time buyer into a repeat customer.

When does it make sense to increase investment in Google Ads?

Once the foundations are solid, these are the assumptions in which it makes sense to consider an increase in investment in Google Ads, always with a solid and coherent strategy behind it:

Performance and scalability

  • Campaigns limited by budget: If you have campaigns with a ROAS well above your target and the indicator «Share of impressions lost per budget» is high, you are losing sure sales. In that case, it does make sense to invest more in the campaigns, but always increasing this value little by little to avoid the campaigns being put on apprenticeship.
  • Market share margin: if your «share of top impressions» is low despite having good ads, raising your bid or budget will allow you to gain visibility against your competitors.
  • Catalog increase at Merchant Center: If we are going to increase our product catalog in Merchant Center substantially, we will need more budget so that Google can test and give visibility to those new products.

Product life cycle and market

  • Launches and new products: If the product is unknown, the initial investment does not seek an immediate return, but rather to generate demand and educate the consumer. Here the investment acts as a discovery engine and, well invested at the top of the funnel, will eventually revert to shopping campaigns. It is important that this type of budget is separate from the performance budget, since we cannot analyze results under the same KPIs.
  • Growth in demand: There are sectors that experience large seasonal peaks in demand. If the volume of searches in your sector rises, your investment must follow this trend so as not to lose ground. Example: toys, swimming pools...

Full Funnel Strategy and Branding

As in the launching of new products, in these cases the investment must be separated from the one destined to performance.

  • Top-of-field inversion (TOFU): Not everything is direct sales. Investing in Video o Demand Gen helps to nurture your remarketing audiences. It is a medium-term investment to make your future sales cheaper. 
  • Rebranding or brand image: When the company changes its identity or positioning, Google Ads is the fastest tool to communicate the new message on a large scale.
  • Discovery of own brands: if you are a distributor, but you are starting to promote private label or exclusive brands, you will need an extra investment specifically dedicated to positioning these new options in the customer's mind.

In short, increasing the budget in Google Ads is not a guarantee of more sales or higher profitability.. Scaling successfully involves much more than investing more money: it requires having an optimized account, a website that converts and a solid business model that can absorb growth without generating friction. 

Only when these foundations are well-built does it make sense to increase investment, and always strategically, progressively and in line with the company's objectives of the business.
