How To Split Your Budget Between Search And Shopping Campaigns

One of the most common questions that comes up when managing Google Ads accounts is how to split your budget between Search and Shopping campaigns. It is a genuinely important question, and yet there is no universal answer that works for every business. The right budget split depends on your industry, your products, your margins, and quite honestly, what you are trying to achieve. Get it wrong and you will either leave money on the table or burn through your budget without the returns you were hoping for. Understanding how to approach this decision is one of the most valuable things you can do for your paid search strategy.

Why The Budget Split Matters More Than You Think

Search and Shopping campaigns serve slightly different purposes, even when they are both driving traffic to the same products. Google Search campaigns allow you to target specific keywords, write tailored ad copy, and capture demand from people who are actively searching with intent. Shopping campaigns, on the other hand, pull directly from your product feed and present visual listings that show the product image, price, and retailer name before someone even clicks. Both are powerful, but they work differently, and understanding that distinction is the foundation of making a smart budget allocation decision.

If you push too much of your budget into Search and neglect Shopping, you may be missing out on highly visual, high-converting traffic at a lower cost per click. If you over-invest in Shopping without enough support from Search, you risk losing visibility for branded terms, competitor queries, and specific high-intent searches that Shopping alone cannot fully capture. The goal is to find the right balance for your specific situation, not to follow a rule of thumb that was written without your business in mind.

Start With Your Business Type and Goals

The first thing to consider is what kind of business you are running and what your primary objective is. If you are an e-commerce retailer with a large product catalogue, Shopping campaigns are likely to be one of your most efficient channels. The ability to showcase product imagery alongside pricing gives shoppers exactly what they need to make a quick decision, and the cost per click for Shopping is often lower than equivalent Search traffic. In this scenario, it would be reasonable to allocate the larger portion of your budget towards Shopping, with Search supporting branded terms and high-priority categories.

If you are a niche retailer selling fewer products at a higher price point, Search campaigns may deserve greater investment because the purchasing journey is longer, more considered, and driven by specific queries that need detailed, persuasive ad copy to convert. A customer spending a significant sum on a product is likely to research carefully, and Search ads give you the ability to speak directly to their concerns with precise messaging in a way that Shopping cannot.

Use Performance Data To Guide Your Allocation

If your account has historical data, this is your most reliable guide. Look at your cost per acquisition, return on ad spend, and conversion rate across both campaign types. If your Shopping campaigns are consistently delivering a stronger return on ad spend at a lower cost per click, the data is telling you something important. Equally, if your Search campaigns are driving higher-value orders or converting customers who go on to become repeat buyers, that has to factor into how you think about budget.

For accounts that are just starting out without historical data, a sensible approach is to begin with a roughly even split and allow both campaign types to gather meaningful data over four to six weeks before making any significant adjustments. Do not make drastic changes based on just a handful of conversions. Statistical significance matters, and pulling budget too early from a campaign that has not had the chance to properly optimise is a mistake that is easy to make and costly to recover from.

Consider The Role of Product Feed Quality

Shopping campaign performance is heavily dependent on the quality of your product feed. If your titles are vague, your descriptions are thin, or your pricing is uncompetitive, Shopping will underperform regardless of how much budget you put behind it. Before committing a large portion of your budget to Shopping, it is worth investing time in auditing and improving your feed through tools like Google Merchant Center. A well-optimised feed with accurate titles, strong descriptions, and competitive pricing will almost always outperform a poorly structured one, and this directly impacts whether your Shopping budget is well spent or wasted.

Search campaigns are more directly in your control because you write the ads yourself. You choose the keywords, the messaging, and the landing pages. This level of control means that even a modest Search budget can perform well when managed properly. Shopping requires that same discipline but applied to your feed rather than your copy.

Think About The Customer Journey and Funnel Stage

Another dimension to consider when thinking about how to split your budget between Search and Shopping campaigns is where in the customer journey each campaign type typically sits. Shopping tends to perform particularly well for customers who are closer to a purchase decision. They know what they want, they are comparing options, and the visual format of a Shopping ad helps them quickly assess whether your product meets their needs.

Search campaigns have a broader reach across the funnel. You can target informational queries, comparison searches, and high-intent buying terms all within the same campaign type, and you have the flexibility to write ad copy that speaks to each stage. If brand awareness and top-of-funnel traffic are part of your objectives, Search campaigns are better placed to support that goal.

Seasonality and Promotional Periods

Your ideal budget split is not a static number that you set once and forget. Seasonality has a meaningful impact on how each campaign type performs, and your allocation should reflect that. During major retail events like Black Friday or the Christmas trading period, Shopping campaigns often see a significant uplift in both traffic and competition, and having the budget to compete during those windows is critical for e-commerce businesses.

During quieter periods, it may make sense to rebalance slightly towards Search to maintain brand visibility and capture the lower volumes of high-intent traffic that are still converting. Building a seasonal budget plan at the start of each year, rather than reacting to performance changes month by month, puts you in a far stronger position to manage your spend effectively.

Reviewing and Adjusting Over Time

Whatever split you start with, it should be reviewed regularly. Set a schedule for reviewing campaign performance, whether that is weekly or fortnightly, and be prepared to move budget between campaign types based on what the data is showing you. An account that was performing well with a 60/40 split in favour of Shopping three months ago may need to rebalance if a competitor has become more aggressive in the Shopping auction, or if you have launched a new product range that performs better through Search.

Tools like Google Keyword Planner and the Search Terms report within your Google Ads account are invaluable for spotting new opportunities and understanding where your budget is being consumed. Use them regularly rather than treating them as occasional references.

Bringing It All Together

Knowing how to split your budget between Search and Shopping campaigns is less about finding a magic number and more about understanding your business, your products, and what your data is telling you. Start by considering your objectives and the nature of your product catalogue. Use historical performance data where it exists, and give new campaigns time to generate meaningful results before making judgements. Keep your product feed in good shape, think carefully about the customer journey, and plan ahead for seasonal peaks. Most importantly, treat your budget split as a dynamic decision that evolves as your account matures, rather than a fixed rule you set once and never revisit. The accounts that perform best over time are the ones where the budget is always working hardest, and that requires ongoing attention, analysis, and a willingness to adapt.
