Every marketing team operates with a working library of “best practices” — heuristics that started as someone’s specific finding, got generalized in a conference talk, and now circulate as universal advice.
Some of them remain genuinely useful. Others survived past their expiration date and now actively damage the campaigns built around them. Leadia Solutions OÜ, a performance-driven marketing partner working across the customer journey, fields questions on this topic from clients almost daily. According to Leadia Solutions, the honest answer is that the same “best practice” can be helpful in one context and lazy in another — and the discipline worth building is the discipline of asking which context applies. This FAQ collects the questions Leadia hears most often, with the answers experts at Leadia Solutions suggest companies sit with.
Are marketing best practices ever genuinely useful?
Of course, if they contain valuable insights into patterns gained through experience and confirmed across many scenarios. For instance, “always test creativity,” “segment your audience before investing in a budget,” and “evaluate the performance of cohorts rather than campaigns” are still around because the core rationale applies broadly.
The easy way out is when marketers apply the name without comprehending the underlying principles — for example, using an A/B test sample size too small to draw conclusions or creating meaningless segments that share behaviors.
When does a best practice become lazy?
Leadia Solutions suggests four warning signs:
It’s repeated without reference to the specific context that produced it
It’s applied identically across channels with very different mechanics
It produces decisions no one can defend with current data
It substitutes for thinking rather than accelerating thinking
When any of these are true, the practice has stopped being a tool and started being a script.
How can a marketing team tell the difference in real time?
Experts at Leadia Solutions suggest a simple test: ask whoever is invoking the best practice to articulate the specific evidence that supports it for this business, this channel, and this audience. If the answer is “everyone does it this way,” the practice is functioning as a default rather than a decision. If the answer references measurable evidence the team can verify, the practice is doing useful work.
Are some best practices universally outdated by now?
A handful of marketing maxims circulate well past their useful life:
“Higher click-through rates always mean better creative”
“Last-click attribution is good enough for most decisions”
“Frequency caps should be set at 3”
“Mobile traffic and desktop traffic should be optimized the same way”
“Brand campaigns can’t be measured against performance metrics”
None of these are uniformly wrong. All of them are uniformly outdated as universal advice.
The deeper problem is that marketing teams often feel like they’re measuring rigorously when they aren’t. Nielsen’s 2025 Marketing ROI Blueprint surfaced exactly this gap: globally, 85% of marketers report being extremely or very confident in their ability to measure holistic ROI, but only 32% actually measure traditional and digital spending in a truly holistic way. That’s a roughly 50-point gap between perceived capability and actual practice. Leadia Solutions OÜ reads this as the clearest possible warning sign — when confidence dramatically outruns measurement reality, the “best practices” guiding decisions are almost certainly riding on assumption rather than evidence.
What about platform-recommended best practices? Are those different?
This is one of the more nuanced questions Leadia Solutions gets. Platform-recommended practices — the guidance Meta, Google, and similar platforms publish — are optimized for outcomes the platforms can measure within their own walls. They’re often genuinely useful for in-platform performance. They’re sometimes misaligned with business outcomes measured outside the platform.
The performance marketing toolset by Leadia Solutions OÜ used internally is built around this principle: layer platform recommendations on top of business-outcome measurement, and let the data resolve the tension when it appears. Treating platform recommendations as inputs to evaluate against business data, not as instructions to follow, is the consistent posture worth building.
How does Leadia Solutions weigh testing best practices versus following them?
The test isn’t testing versus following. It’s understanding why a practice works before either testing it or adopting it. A team that understands the mechanism behind a practice can adapt it intelligently. A team that’s only memorized the headline will either follow it blindly or test it badly.
Are there best practices Leadia Solutions OÜ consistently recommends?
Yes — a small set that holds up across nearly every B2B context:
Define the downstream business metric before building the campaign. Reverse-engineering campaign goals from existing creative leads nowhere good.
Build cohort-level measurement before scaling spend. Aggregate metrics hide the truth that cohort metrics reveal.
Maintain creative diversity within active campaigns. Creative fatigue is the most predictable cause of performance decay.
Treat audience definition as a discipline, not a one-time setup. Audiences shift; static audience definitions silently degrade campaigns over time.
Review channel mix against incremental contribution quarterly. Channels that produced last year’s wins rarely produce next year’s at the same rate.
These hold up not because they’re trendy but because the underlying logic is durable.
What’s the single most lazy thing teams do with best practices?
The consistent answer: copying the practice without copying the measurement that justified it. A best practice without its measurement context is folklore. The measurement is what makes it useful — without it, the practice is just confident-sounding guesswork. And as the Nielsen research above suggests, confident-sounding guesswork is exactly what most marketing teams unknowingly produce.
How often should best practices be re-evaluated?
Quarterly review of operational best practices, annual review of strategic ones. Quarterly is fast enough to catch shifts in platform mechanics and audience behavior. Annual is appropriate for higher-order decisions about channel mix, attribution philosophy, and measurement architecture.
What replaces best practices when they fail?
Not the absence of practice — that’s chaos. What replaces a failed best practice is a better one, derived from current data in the current context. Marketing teams should always be running a small portfolio of practices on probation: practices that have worked historically but are due for re-validation. When the data confirms them, they continue. When it doesn’t, they’re replaced with the next candidate.
The Posture Worth Building
For B2B companies trying to decide whether their marketing operates on living practice or inherited folklore, Leadia Solutions OÜ believes the most valuable shift is treating best practices as hypotheses with expiration dates rather than as rules. The teams that build this posture stop arguing about whether a given practice is “right” and start asking whether it’s still earning its place in the current portfolio. Leadia Solutions views this discipline — the willingness to question what’s working as rigorously as what isn’t — as the difference between marketing organizations that compound and marketing organizations that stagnate.
