Google Ads vs Meta Ads: Which Platform Should Your Business Be On

This question comes up constantly and most of the answers online are useless because they hedge. "It depends on your goals." "Both have their place." That is not advice. That is word count.

Here is a direct answer based on the actual campaigns we manage, the results we have seen, and the specific conditions under which each platform earns its budget.

The Intent Difference

This is the fundamental distinction that every other decision flows from.

Google captures existing demand. Someone types "Greek restaurant Unley" into Google. They are already looking for what you sell. Your job is to be there when they are ready. The intent is established before your ad appears.

Meta creates demand. Someone is scrolling through their feed and sees an ad for a coffee subscription box they did not know they wanted. No search happened. Meta placed your product in front of a person based on behavioural and demographic data. Your ad has to do the work of making them interested.

These are different marketing jobs. Capturing existing demand requires being relevant at the right moment with a compelling offer. Creating demand requires stopping someone mid-scroll and making them feel something about a product they were not thinking about. Both are valuable. They are not interchangeable.

The Product Types That Suit Each Platform

Google is the right primary platform when:

The purchase decision starts with a search. Services (plumbing, legal, medical, accounting, marketing), local businesses (restaurants, cafes, gyms), and products where people know what they want and search for it (specific appliance models, branded products, standardised B2B services) all perform well on Google because the intent is explicit.

Price points are high enough to justify cost-per-click. Average CPCs in Google for competitive categories in Australia run from $2 to $15 depending on the industry. If your average transaction is $40, a $6 CPC is a hard model to make work. If your average transaction is $400, that same CPC is very manageable.

Geographic targeting matters. Local service businesses, restaurants, medical practices, and retail stores benefit from Google's location-based search intent. "Dentist North Adelaide" is a high-intent search that converts well. Meta can target by location too but cannot capture that moment of active need.

Meta is the right primary platform when:

The product benefits from visual presentation. Food, fashion, homewares, beauty, fitness, and lifestyle products that photograph or film well have a natural advantage in a visual feed environment.

The audience can be defined demographically and behaviourally without relying on active search. An Nam Quan, a Vietnamese restaurant client, achieved a $0.12 CPC and a MER of 27.95 through Meta campaigns targeting food-interested audiences in the Adelaide metro area. That CPC would be impossible on Google for restaurant terms.

You are building brand awareness alongside direct response. Meta's reach at relatively low CPM allows you to maintain brand visibility for audiences that are not actively searching. This compounds over time in a way that purely search-driven marketing does not.

The product is discovery-based. Gifts, subscription products, novel products in new categories, and anything where the customer does not have a name for what they want yet all need discovery-based advertising.

Budget Thresholds That Make Each Platform Viable

This is practical. Minimum budgets to get meaningful data from each platform.

Google Ads: $50 to $100 per day minimum for a single campaign to generate enough conversion data for the algorithm to optimise effectively. Below that level, you are running in a permanent learning phase without enough conversions to make smart bidding work. For competitive categories in Adelaide (legal, medical, finance), viable budgets start higher.

Meta Ads: $30 to $50 per day minimum for a single ad set. Meta's algorithm needs 50 conversion events per week to exit the learning phase. With lower daily budgets, that takes longer or never happens, and performance stays flat.

For businesses with $500 to $1,000 per month in ad budget, pick one platform and do it properly. Splitting that budget across both platforms produces underperformance on both. For businesses with $3,000 or more per month, a split makes sense once you know which platform produces your core conversions.

The Restaurant Case: We Use Both, For Different Objectives

Greek Street Unley runs campaigns on both platforms, but for explicitly different purposes with different conversion objectives.

Google Search captures high-intent local queries: "Greek restaurant Unley," "function room Adelaide," "private dining Adelaide." These are people actively looking. The conversion goal is a reservation. The click value is high because the intent is high.

Meta runs to drive brand familiarity and reach food-interested audiences in the inner south suburbs who are not yet thinking about where to eat next Saturday night. The creative is visual: the food, the space, the atmosphere. The objective is awareness and consideration, not immediate booking. A person who sees the Instagram ad 3 times in a month and then searches for "Greek restaurant Unley" on a Friday is a conversion that Google will claim credit for. It was also influenced by Meta.

The two platforms are addressing different stages of the same purchase decision for a restaurant. Trying to run the same objective on both, or expecting immediate conversions from Meta awareness spend, produces the wrong conclusions.

The E-Commerce Case

For an e-commerce business like BLK MRKT Coffee, the decision depends on product category maturity. Coffee subscriptions exist as a category that people search for. Google captures that intent. But coffee as a product is also extremely visual and discovery-friendly on Instagram.

The right starting point for e-commerce with limited budget: start with Meta because the cost to reach your target audience is lower, the creative format suits physical products, and Meta's algorithm can find lookalike audiences from a customer list quickly. Once Meta is profitable, add Google to capture the explicit search demand that your Meta awareness has helped create.

The Recommendation Framework

Answer 3 questions.

1. Do people search for what you sell? If yes, Google is essential. If no, Google is optional.

2. Is your product visual or lifestyle-oriented? If yes, Meta has a natural advantage. If no, Meta requires stronger creative investment to work.

3. What is your average transaction value? Above $200, both platforms are financially viable on reasonable budgets. Below $80, Google requires high conversion rates to justify CPCs in most categories. Meta's lower CPCs make it more accessible at lower transaction values.

The combination answer is almost always some version of: start with the platform that matches your intent type, prove profitability there, then layer in the second platform for a different objective in the funnel.
