The biggest challenges facing digital marketers

Key takeaways

• Measurement is harder because privacy rules, browser limits and cross-device behavior break user-level tracking, so teams now combine data-driven attribution, incrementality tests, marketing mix modeling and first-party data.
• Third-party cookies are already blocked by default in Safari and Firefox; Google kept them in Chrome in 2025 and dropped its plan for a new prompt, but cookie-dependent tactics remain fragile.
• AI search is cutting clicks: Pew Research Center found Google users clicked a traditional result in 8% of visits when an AI summary appeared, compared with 15% when none did.
• Rising acquisition costs and content saturation reward conversion improvements, retention, owned channels and original research over more spending and more volume.
• About 20 states now have comprehensive consumer privacy laws in effect, so consent management and data minimization are standard requirements.

Marketing teams now face problems that go beyond technology into strategy, organization and budget. Understanding why digital marketing has become harder helps teams build strategies for current conditions rather than those of five years ago.

Why is measuring marketing performance getting harder instead of easier?

Measuring performance is getting harder because privacy rules, browser tracking limits and customers moving between devices and platforms have eroded the precise attribution digital marketing once promised. Teams could once see which channel, ad or message produced a sale; now much of the path is invisible.

Last-click attribution was always flawed, and it’s less accurate than ever. Someone might hear about a brand on a podcast, look it up on a phone and buy on a laptop weeks later, and last click credits only the final paid search ad. Google Analytics 4 now offers data-driven attribution and last click after Google retired its rules-based models such as position-based in 2023.

At Emulent, attribution has become one of our hardest client conversations, because everyone wants a clean answer and clean attribution no longer exists as it once did. The goal now is directional accuracy, and teams that accept that make better decisions than those chasing a number that can’t be measured.

Four approaches that help marketers work through attribution gaps:

How have changes to third-party cookies affected what marketers can do?

Changes to third-party cookies have weakened cross-site targeting, retargeting and measurement, though not as completely as once predicted. Safari and Firefox block third-party cookies by default, and Chrome’s Incognito mode does too. Google spent years planning to remove them from Chrome, then in April 2025 announced it would keep its current approach, leaving users to control cookies in Chrome’s settings, and it later retired several Privacy Sandbox technologies.

So cookie-based tactics still work for much of Chrome’s audience but fail for a large share of browsers and users who block them, and consent rules limit them further. Programs built on third-party audience segments, cross-site retargeting pools or tracking without consent remain exposed, and some teams have already lost campaign types that once produced meaningful revenue.

Four first-party strategies that reduce dependence on third-party cookies:

• Email and CRM growth. An email address is a direct line to a customer that no platform change can take away. Teams that treat list growth as a core metric build an owned audience whose value rises as third-party options shrink.
• First-party on-site tracking. Server-side tracking and first-party cookies on your own domain aren’t affected by third-party restrictions, and strong event tracking supports personalization and optimization.
• Customer data platforms. A CDP combines website, CRM, email and point-of-sale data into unified profiles for segmentation without third-party data brokers.
• Contextual targeting. Placing ads based on page content rather than viewer identity reaches relevant audiences without user-level tracking.

What is AI’s actual impact on digital marketing work right now?

AI’s biggest impacts right now are a flood of easily produced content and fewer clicks from search. Generative AI speeds up writing, images and ad copy, but because every competitor has the same tools, more output alone doesn’t help and adds to content overload.

AI answers are also absorbing clicks. In a Pew Research Center analysis of 68,879 Google searches by 900 U.S. adults, users clicked a traditional result in 8% of visits when an AI summary appeared, compared with 15% when none did, and clicked a link inside the summary in just 1% of visits. Teams that relied on informational search traffic have seen the biggest effect.

Four ways marketers are adapting to AI’s effect on search and content:

• Target queries AI answers poorly. AI handles simple factual questions well but struggles with local knowledge, recent events, opinion, first-hand experience and proprietary data. Shifting content toward those areas reduces direct competition with AI answers.
• Create content AI systems cite. AI Overviews and similar tools draw on trusted sources. Strong E-E-A-T, original research and citations from respected sites make your content more likely to appear in AI answers.
• Use AI for research and refinement. Teams that use AI to speed research, find content gaps, test messages and analyze performance gain productivity; teams that mass-produce finished content with it often see weaker results than those publishing expert-created work.
• Invest in owned channels. Email, SMS, communities and direct subscriptions reach audiences without depending on search, which stabilizes marketing if search traffic falls.

AI doesn’t shortcut to better results; it amplifies what you bring. Strong strategy, positioning and expertise get executed faster, and weak ones just produce weak content faster.

Why do customer acquisition costs keep rising, and how can teams respond?

Customer acquisition costs keep rising mainly because more advertisers compete for limited ad inventory on platforms such as Google and Meta, and auction pricing climbs as competition grows. That affects paid search, paid social and programmatic advertising alike.

Higher costs hit hardest for businesses with thin margins, long sales cycles or low customer lifetime value. If acquiring a customer costs as much as the first purchase earns, paid acquisition can’t be the main growth engine, and teams have to find growth within tighter budgets.

Four strategies for managing acquisition costs:

• Improve conversion before raising spend. Doubling your conversion rate halves cost per acquisition. Fixing landing pages, checkouts and lead forms pays off across every paid channel.
• Build organic channels. SEO, content marketing and organic social bring traffic at a lower cost than paid ads, and a balanced mix lowers blended acquisition cost over time.
• Invest in retention and lifetime value. Keeping customers usually costs less than finding new ones. Loyalty programs, repeat-purchase offers and post-purchase email grow revenue from existing customers.
• Tighten targeting. Broad paid social targeting shows ads to many people who won’t convert. First-party lookalike audiences, CRM segments and behavioral data concentrate budget on likely buyers.

How is content saturation making it harder to build organic visibility?

Content saturation makes organic visibility harder because publishing alone no longer earns attention. More pages compete for each query, the cost of producing mediocre content has collapsed and the pages that rank consistently show clear topical authority, strong E-E-A-T and depth thinner content can’t match.

Organic social reach has followed the same path. Facebook, Instagram and LinkedIn distribute brand content to a smaller share of followers than they once did, so organic social only drives meaningful results when content earns real engagement.

Four content strategies that cut through saturation:

• Original research and proprietary data. Findings available nowhere else earn citations, links and visibility that rewritten content can’t, making your page a primary source.
• Depth on focused topics. Sites that cover a narrow area thoroughly, including common questions, comparisons and subtopics, usually outperform sites that cover many subjects lightly.
• Content that fills real gaps. Before writing, study what already ranks and find what it misses. Filling that gap beats copying what’s already strong.
• Distribution matched to production. Expecting algorithms to distribute strong content on their own is unreliable. Email, social promotion, community sharing and publication outreach give content the early momentum it needs.

How are privacy regulations changing what digital marketers are allowed to do?

Privacy regulations are adding consent requirements, opt-out rights for data sale and sharing, limits on sensitive data in targeting and disclosure obligations, and the rules vary by state. The U.S. has no single federal privacy law; about 20 states now have comprehensive consumer privacy laws in effect, starting with California, and more have passed laws that take effect later. For national brands, compliance is an ongoing process that changes with each new law.

Brands that haven’t reviewed their marketing data practices against current state requirements are likely out of compliance somewhere, with real financial and reputational risk.

Three privacy practices that protect marketing programs:

• Consent management platforms. A CMP records and honors cookie and tracking consent across jurisdictions and is now a basic requirement for collecting behavioral data.
• Data minimization. Collect only the data you need and use. Regularly audit what marketing systems capture and remove the rest, which lowers both legal and security risk.
• A clear value exchange. People share data more readily when they know what they get in return. Plain explanations of what you collect and why build trust and durable opt-in rates.

Privacy regulation will keep expanding. Brands that treat compliance as a minimum and respect user preferences beyond it build trust, while those treating it as a checkbox will keep playing catch-up.

How do you build a digital marketing practice that holds up against these pressures?

You build a resilient practice by accepting these conditions as permanent and designing around them: directional measurement, first-party data, owned channels, conversion and retention work and content with real expertise. Complex measurement, privacy rules, rising costs, AI-driven search and content overload won’t fade on their own. Not every trend hits every business equally, though; a local service company with strong referrals may feel AI search far less than a publisher, so focus first on the problems that show up in your own numbers.
