Some of the world's biggest consumer-goods firms are ratcheting down ad spending, starving Madison Avenue of revenue and further threatening ad firms and ad-dependent media companies already coping with a rapid shift to digital advertising.

Shares in the world's largest advertising company, London-based WPP PLC, fell nearly 11% Wednesday after it reported a steeper-than-expected slowdown in global ad buying, particularly from consumer-goods companies. It was the stock's biggest one-day drop in more than 18 years. Stocks of rivals also tumbled.

WPP, which owns agencies such as J. Walter Thompson, Young & Rubicam and Ogilvy & Mather, said the pain was global, with North American advertisers pulling back especially hard.

Consumer-goods companies, including Procter & Gamble Co. and Unilever PLC and packaged food giants like Kraft Heinz Co. and Nestlé SA, have typically driven revenue at the world's biggest agencies. But these clients are struggling to boost sales amid pressure on multiple fronts. To cope, they have been cutting back on spending.

WPP Chief Executive Martin Sorrell on Wednesday said the pullback was cyclical but cautioned that it's a "big wake-up call." Sales volumes at consumer-goods companies "are flat or falling," Mr. Sorrell said. "It means you have less consumers, and that's the beginning of serious problems."

The penny pinching has been widely telegraphed, but the sharp declines at WPP shocked investors.

Already, the world's largest advertising companies have been coping with marketing clients reviewing their agency contracts to reduce costs, questions about the effectiveness and quality of digital advertising, digital ad fraud, and demands for assurances that ads won't run alongside inappropriate content.

The pressures in the industry have been exacerbated by a breakdown in trust between marketers and agencies. A report from the Association of National Advertisers last year found that ad agencies were accepting rebates from media companies without clients' knowledge, stoking concerns about transparency. Big ad companies denied wrongdoing.

Ad companies' revenue growth is slowing as companies continue to cut the fees they pay agencies and amid growing competition from consulting firms, said Brian Wieser, a senior analyst at Pivotal Research Group.

There is also heightened competition from clients creating in-house marketing and digital buying groups and from media companies creating bespoke brand content.

"I do think the spending levels will return," said Wenda Harris Millard, a media veteran and vice chairman of consultancy MediaLink. "There's just a confluence of factors that are making people very, very nervous."

In response, ad-holding companies such as WPP have been simplifying their organizational structures and consolidating agency groups to be more nimble and coordinated in response to client requests.

Marketers, meanwhile, have been auditing their agency contracts and frequently switching firms or reducing the number of agencies they work with.

P&G, long the biggest advertiser in the world, reduced digital ad spending by $100 million in the last quarter. It said the reductions came mostly from cutting out what it found was largely ineffective digital advertising. It also reduced overhead, agency fee and ad-production costs in the quarter.

"We want our advertising to be seen by real people, not bots, and where we could be assured that our brands would not appear next to objectionable content," a P&G spokeswoman said, adding that the company has been outspoken about identifying "fraud and waste" in the ad industry.

Others are experimenting. Unilever, the Anglo-Dutch maker of Dove soap and Hellmann's mayonnaise, and WPP's biggest client, has been turning to YouTube stars and beauty bloggers to push its products, diverting some money from traditional advertising channels. Earlier this year, it said it planned to cut the number of ads it created by 30% and reduce the number of creative agencies it works with by half.

Kraft Heinz, Mondelez International Inc. and Kellogg Co. are also shifting more marketing dollars to nontraditional forms of advertising, including hiring people with influential social media presence to promote their brands. A report by Nielsen showed that 92% of consumers trust that type of advertising over traditional marketing.

Carli Evilsizer, head of marketing at the privately held snacking company Graze, said with these so-called influencers, "for a relatively small amount of money, we're reaching a large amount of customers who are the right people for Graze. It is game changing."

Still, digital ads are growing strongly. Worldwide revenue is projected to increase 17% this year to $223.7 billion, according to eMarketer. In a period of confusion about the kind of advertising that works, analysts say companies are choosing to tighten their belts, or experiment on their own.

"All of a sudden, marketers realize that they don't know what they're buying," said Charles Bedouelle, an analyst at Exane BNP Paribas, adding: "The clients are lost."

Google parent Alphabet Inc. and Facebook Inc. aren't showing signs of taking on the creative role that big ad agencies say clients need. Still, they wield enormous clout as media sellers, capturing 77 cents of each new digital ad dollar spent, and their ability to target ads is the envy of ad land.

Shares in other advertising giants, as well as media companies reliant on selling ad space to them, also tumbled Wednesday. Omnicom Group Inc. shares fell 7%. Interpublic Group of Cos. dropped more than 6%, and France's Publicis Groupe SA slid more than 3%.

The S&P 500 Media Index fell 1.45%. Axel Springer SE, the Berlin-based publisher of Germany's mass-market Bild newspaper and operator of the N24 cable-news station, ended down 1.4%. British broadcaster ITV PLC closed 1.9% lower.

Those moves came after WPP said like-for-like net sales fell 0.5% in the first half of the year, from a year earlier. In July alone, they fell 2.6%. The company also lowered its net sales growth forecast for the full year to 1% or less.

Its closest competitors face similar headwinds. Japan-based advertising company Dentsu lowered its full-year net sales guidance by 1.5% earlier this month, citing ad account reviews at consumer-goods firms. Last month, Interpublic said spending cuts by such clients hit revenue.

Consumer-goods companies have all struggled with a host of headwinds. Changing tastes are favoring healthier, fresher options for food makers. New, often smaller, local upstarts are competing for sales of everything from shaving cream to ice cream. Low inflation in many parts of the world has kept them from raising prices to make up for slowing volumes.

The industry -- in many cases encouraged by activist investors -- has responded by cutting back on costs. Nelson Peltz's Trian Fund Management is agitating at P&G, though it has specifically objected to P&G's decision to cut advertising. Daniel Loeb's Third Point has taken a big stake in Nestlé.

A key cost-cutting strategy for many firms has been so-called zero-based budgeting, the practice of justifying every cost from scratch each year. The tool was made popular by 3G Capital, the Brazilian investment fund that rolled it out in recent years at companies like Kraft and Anheuser-Busch InBev NV.

The strategy can be particularly painful for ad executives, who essentially have to justify their campaigns to clients each year. WPP's Mr. Sorrell specifically blamed zero-based budgeting among clients for some of his company's woes. Still, he said there are indications consumer goods companies are planning to increase their spending again as early as the latter half of the year.

"Whether they have the vim and vigor to do that given the current market situation is another story," Mr. Sorrell said. "We will have to see how those activist situations, zero-based budgeting situations play out over time."
