Marketing today is more expensive, more competitive, and more complex than ever. According to Gartner, average digital marketing spend as a percentage of company revenue rose from 6.4% in 2021 to 9.1% in 2024. Yet many brands still struggle to get consistent ROI.

The reason? You’re likely overpaying for channels that no longer deliver the efficiency they once did.

This isn’t a "cut your budget" article. It’s a wake-up call to rethink how and where you’re investing your dollars—because most brands are leaving profit on the table every month.

Here are the three channels where we most often see waste—and how to fix them.

1. Google Search Ads (When They're Not Properly Segmented)

Google Ads can still drive high-intent traffic, but the cost-per-click has been climbing steadily. As of 2025, average CPCs are up 18% year-over-year, and in some industries like eCommerce, SaaS, and legal, CPCs have doubled in just two years.

Where it goes wrong:

• Broad match keywords with poor intent

• Competing in overly saturated categories

• Lack of negative keywords and irrelevant placements

• Sending traffic to weak or generic landing pages

• Not separating branded vs. non-branded campaigns

The Fix:

• Use Exact Match and Phrase Match for high-intent queries, and limit Broad Match to exploratory campaigns with capped budgets

• Create tight ad groups that mirror search intent and align with tailored landing pages

• Set negative keywords proactively to avoid wasting spend on irrelevant clicks

• Regularly audit your search terms report to eliminate low-quality traffic sources

• Split branded campaigns from generic search to track ROAS more accurately

According to WordStream, brands that actively manage and refine keyword targeting see 33% lower CPCs and 50% higher Quality Scores, which directly impacts cost efficiency.

2. Social Media Boosting (Instead of Structured Paid Strategy)

"Boost post" is the most misleading button in digital marketing.

Yes, Meta (Facebook & Instagram) and TikTok remain powerful platforms, but boosting content without structure or targeting is a fast way to waste cash. As of Q1 2025, Meta’s ad CPMs have jumped to an average of $17.60 globally (Source: AdStage), while TikTok CPMs are rising rapidly due to demand.

Where it goes wrong:

• Spending on vanity engagement instead of conversion-focused campaigns

• No clear objective (reach, video views, or clicks?)

• One-size-fits-all creatives that don’t speak to each audience layer

• Letting campaigns run without frequent optimization

• Not segmenting cold, warm, and hot audiences

The Fix:

• Run structured campaigns through Meta Ads Manager or TikTok Business Center, not just boosted posts

• Define your campaign objectives clearly: TOF (awareness), MOF (consideration), BOF (conversion)

• Create segmented ad sets for cold audiences vs. retargeting audiences

• Use dynamic creative testing and rotate assets every 7 to 10 days to avoid fatigue

• Pair your ads with high-converting landing pages, not generic homepages or product listings

Data from Meta shows that structured campaigns outperform boosted posts by over 70% in terms of ROAS and conversion rate. Boosting is fast, but structured strategy is what actually works.

3. Influencer Marketing Without Attribution Tracking

Influencer marketing has exploded over the last few years, but the majority of brands are still doing it wrong. According to Influencer Marketing Hub's 2024 report, 67% of brands don’t measure the ROI of influencer campaigns accurately, and nearly 40% rely solely on likes or comments to gauge success.

Where it goes wrong:

• Paying flat fees without performance-based contracts

• No UTM tracking or affiliate codes to monitor conversion

• Choosing creators based on following size instead of engagement rate or niche relevance

• One-off collaborations without follow-up touchpoints

• Using influencer content in silos instead of repurposing across paid media

The Fix:

• Use performance-based agreements with clear metrics (clicks, conversions, reach)

• Implement UTM parameters, unique codes, and pixel tracking to attribute results

• Prioritize micro-influencers (5K–50K followers) with strong engagement over mass reach

• Build long-term partnerships and follow up with owned channel flows (email/SMS)

• Repurpose influencer content in your paid ads, landing pages, and email campaigns for added ROI

A Nielsen study found that influencer content repurposed for paid ads delivered 4x higher engagement rates than brand-generated content alone.

Bonus Channel: Organic Social (Without a Purpose)

Organic social still plays a role, especially for community building and customer service—but expecting it to drive large-scale reach or conversions in 2025 is unrealistic without paid amplification.

Posting regularly is not a strategy. It’s noise, unless it fits into your broader content and campaign ecosystem.

Fix it by:

• Aligning posts to your campaign calendar and funnel stages

• Pairing organic content with email and SMS themes

• Using social for community, UGC, testimonials, and retention, not just reach
