Doner successfully refreshed the image of the Chrysler Pacifica by tapping into cultural trends while staying grounded in real family needs.
Chrysler wanted to make the Pacifica more appealing to modern families, and the rise of the #VanLife trend created an opportunity to shift perceptions of the minivan. Doner connected this trend to everyday parenting by highlighting Pacifica’s practical, family-friendly features through engaging video content across broadcast and social media.
By blending aspiration with real-life usefulness, the campaign repositioned the Pacifica and delivered strong results, including a 143% year-over-year increase and a 95% increase in second-quarter sales.
FCB (Foote, Cone & Belding) is a globally recognized advertising agency known for its innovative and effective advertising and marketing campaigns. As part of the Interpublic Group, FCB has a substantial global footprint, with over 120 offices across over 80 countries.
FCB's impact is validated by numerous awards and recognitions in the industry, including the Cannes Lions and Effie Awards. The agency combines creative storytelling with deep insights into consumer behavior, aiming to create accessible advertisements that capture attention and drive meaningful results for its clients.
During the 2022 FIFA World Cup, Brazilian football fans wanted to support their national team by wearing the official jersey. However, the high cost of the jerseys (R$350) was a significant barrier, especially given the inflation Brazilians were facing at the time. This situation challenged FCB's client, Flash, to engage with fans and allow them to express their support.
FCB offered a 50% cashback on jersey purchases from Nike's eCommerce site in exchange for fans customizing the jersey with Flash's brand name and sharing it on social media. This campaign turned fans into brand sponsors and significantly boosted Flash's visibility, getting more than 5.1 million interactions and increasing brand mentions by 2300%.

With its unique All-Inclusive TV model, the agency handles all aspects of a campaign, including media buying, strategy, creative development, production, and reporting.

The strategy is powered by Annika, the agency’s own AI for media buying that analyzes large datasets to optimize media placements across linear and streaming TV. Marketing Architects serves B2B and B2C clients, using TV advertising as a key growth driver.
Joybird, a furniture retailer and manufacturer primarily focused on online marketing, wanted to expand its customer base and reach new audiences through offline channels. Marketing Architects launched TV ads on linear and streaming platforms, minimizing audience overlap with Annika's help.
The campaign led to over 700,000 web visits driven by TV, over 16,000 TV-attributable orders, and 7-10X return on ad spend (ROAS).

"The Last Photo" campaign featured an exhibition of 50 last photos of suicide victims and a 90-second film distributed across television, cinema, outdoor, digital, and social media channels. It also directed the audience to CALM's website for suicide prevention.
"The Last Photo" drew over 500,000 visitors to the exhibition, reached 7.5 million people through live TV, and generated 1.6 billion impressions. Additionally, it became the most talked-about video on Reddit globally for 48 hours and increased online discussions about suicide by 33%.

Nike faced the challenge of promoting women's fitness and sports. W+K created the "Better for It" campaign, inviting women globally to share their fitness journeys and personal bests.
This campaign included "Margot vs Lily", a scripted series about two sisters with differing fitness goals, directed by Tricia Brock. It also launched Nike's first Tumblr site and short films "Inner Thoughts" and "Last," encouraging women to share their fitness missions.
"Margot vs Lily" led to 3.5 million downloads of the Nike Training Club App and inspired two million new workouts. The campaign's Tumblr quickly gained 175,000 followers, becoming the most reblogged fashion brand of 2015. Moreover, two months after the campaign's launch, Nike's women's division sales increased by 20%.

Dole Sunshine Company wanted to address the stigma associated with the "forbidden fruit" to encourage healthier eating and start a global discussion about the importance of fruit. The agency humorously requested Pope Francis to rebrand the fruit's bad image, suggesting a biblical revision to replace "fruit" with an unhealthy snack.
The campaign was launched on International Fruit Day 2022. It generated over 55 million media impressions and appeared in 784 media outlets, including Design Taxi and Bloomberg, earning $2.2 million in media value.

What should you consider before contacting advertising agencies?
Before contacting ad agencies, you must define your priority business objectives, success metrics, ad spend limit, expected timeline, internal decision-maker, and available resources.
Without that foundation, agencies will make different assumptions, which can make proposals difficult to compare and lead you to hire agencies for the wrong problem.
With 71% of CMOs reporting that they lack the budget to fully execute their strategy, it is vital to distinguish between "must-have" and "nice-to-have" campaign features before the first discovery call.
When should you hire a specialist advertising agency vs. a full-service digital marketing agency?
Hire a specialist advertising agency when you are experiencing issues with paid media execution and results. Conversely, hire a full-service digital marketing agency when the larger problem is coordination across channels, brand, content, and web.
Consider specialized ad agencies when:
Paid search, paid social, or media buying is your growth lever, but performance is inconsistent.
You already have brand, web, and content support in-house.
You need faster testing, tighter optimization, and deep platform expertise (e.g., Google Ads and paid media).
Consider full-service digital marketing agencies when:
Your message, funnel, creative, and channel mix need to work together.
You want one partner for different marketing services, such as social media, search engine optimization, email marketing, and performance marketing.
The primary issue is fragmented execution and not just ad performance.
How much should you realistically budget for advertising?
A realistic advertising budget typically ranges from 5% to 15% of your total annual revenue, depending on your growth stage and industry competitiveness.
For example, small businesses typically dedicate 2%-4% of their revenue to PPC advertising, with aggressive, growth-stage organizations typically spending more.
As a market benchmark, Gartner's 2025 CMO Spend Survey found CMOs reporting marketing budgets at 7.7% of company revenue and paid online channels accounting for 69% of digital spend.
The practical takeaway is to ask each shortlisted agency for a minimum viable testing budget by channel, then reject plans that cannot generate enough volume to prove or disprove the strategy.
How should you measure the success of your advertising campaigns?
Measure the success of your advertising campaigns by tracking bottom-line outcomes.
For lead generation campaigns, success metrics may include qualified leads, cost per sales-qualified lead, close rate by source, and pipeline contribution.
For eCommerce brands, success metrics to consider include customer acquisition cost, contribution margin, repeat purchase behavior, and return on ad spend (ROAS).
While platform metrics, such as click-through rate (CTR) and cost per click (CPC), are valuable, consider these as diagnostic metrics rather than success metrics.
How long does it take to see the results of your advertising campaigns?
Advertising campaigns may produce results within a few weeks or days. However, sustained ad performance may take 1-3+ months.
Typically, ad agencies dedicate the first 30 days to campaign ramp-up, data gathering, experimentation, testing, and conversion lag.
Then, they allot days 31-60 for campaign optimization. After 90 days from the campaign launch, you may record tangible outcomes, such as increased leads, higher ticket sales, and revenue growth.
The actual timeline before you see results will depend on current performance, ad channel, ad quality, target niche, industry competition, and the aggressiveness of your advertising campaign.
What common mistakes do businesses make when choosing their ad agencies?
Common mistakes include choosing based on the lowest hourly rates, being overly influenced by the pitch, and failing to confirm ownership of accounts, data, and reporting.
To avoid these mistakes, look for data-backed case studies that match your industry, market niche, and campaign type.
Also, review client feedback and request client references to better understand the agency's project management style, account ownership practices, reporting standards, and approach to campaign optimization.
