Talking Paper: The Scientific Principles Of Media Planning Are Few, but Awesome

No, "Talking Paper" is not some new media device developed at MIT. It's a short-text brief, like those prepared for the President to keep him out of trouble in Burundi.

This is a Talking Paper on the Scientific Principles of Media Planning. It's a brief because there aren't many.

Agreed, scientific principles are no match for the mysteries of life. But media planners still need to be pupils of Science, not its fugitives. And if "principles" seems an over claim, let's think of them as things that seem to work.

There are five media planning ideas worth studying. Targeting, Recency, Satiation, Acceleration and Synergy. It makes for a hopeless acronym.

  1. TARGETING

    Henry Kissinger said the "organizing principle" of Western geo-political strategy was the threat of Communist aggression. I admire the phrase, so I've decided to steal it. The organizing principle of media is "the consumer target", which we need to develop further in our planning.

    Targeting's value is consistently underestimated, because we fix on demographic, user and life style targets, which don't work well for television, where most of the money is still spent.

    When we expand our target to include those more likely to buy for other reasons, it now includes "geo-targeting," and "receptivity" targeting. Both are powerful.

    Geography and Receptivity

    Geo-targeting is a fancy name for spot planning. It works because all brands have good and bad markets, which sell for much the same CPM.

    Receptivity targeting exploits the psychological dimension of response. When I was a kid impatient for my allowance, my mother would advise "ask your father after dinner." That is receptivity targeting. What a person is feeling, doing or thinking at the time of communication can greatly enhance response. Other dinner-related examples:

    A Pizza Hut commercial, before dinner, when we're hungry.
    A "stop smoking" spot after dinner, when we've lit-up, a though we've quit.
    A Weight Watchers commercial Monday, when we've over-indulged all weekend.

    When receptivity requires precise targeting-in-time, it's limited to TV, Radio and the Internet. But in Print, context can create its own receptivity.

    Media people champion the benefits of "environment". That usually means content, quality and even rating level. I would argue what is going on inside the consumer's head when the message is received is the most important environment of all.

    Near-to-purchase

    "Near-to-purchase" is more generalized targeting-in-time. It has leverage because often purchases are concentrated, and the last competing message received is more likely to be remembered. Near-to-purchase targeting works with most media. Seasonality is a special case.

    We vote on election day.
    We decide to order "take-out" between 4 and 8 PM.
    We go to movies and shop cars on weekends.
    We buy insect repellent in the summer.

  2. RECENCY

    Recency is receptivity targeting expanded into a model of advertising effect. The recency model is simple. Advertising works with consumers who are in the market for the product being advertised at the time. It doesn't convince those people they need something. Life does that (the car lease is up). It gets those people to buy a brand (Toyota is having a sale).

    Skimming

    In any selling situation, there are hard and easy sales. Survival dictates a brand go after the easy ones first. Recency is a skimming strategy.

    When a person is ready to buy a product (the corn flakes box is empty), life has already done the hard work. That consumer needs cereal. If you are there with an ad to remind them of your brand (Kellogg's) before they make the purchase, you will get more than your share.

    The problem is you can't target incipient purchasers directly, because you don't know who they are. Instead, you have to reach as many potential purchasers as possible, over as many weeks as the budget will allow, and let probability pull the trigger.

    But recency is not simply reach planning. It stresses reach with continuity. This transforms frequency into something much more valuable in advertising -- continuing brand presence.

    Presence

    The idea of "presence" helps explain the reach-frequency issue. Most advertising doesn't work through repetition. It works by being there at the right time.

    Successful scheduling reminds more people who are ready to purchase the product; about a brand they already know.

    This suggests brands should plan for the highest 52-week total of weekly reaches the budget can afford, because different people are in the market for a product during different weeks, but most people shop each week.

    Frequency is part of the old teaching/learning model. Sellers like the idea of advertising teaching people about products because that seems to deserve a higher CPM.

    The Recency rule on planning interval is "shorter is better". The actual length is a function of budget. McDonald's should plan by the day.

    Using the highest "sum of weekly reaches" as a planning goal, results in schedules of moderate GRP weight and more weeks of advertising.

    ROI Modeling

    For the remaining three planning principles, Satiation, Acceleration and Synergy, we move to a new area of discovery through Return On Investment (ROI) analysis.

    ROI is the philosopher's stone of media measurement. It looks at dollars in and dollars out. What does a dollar spent on the Internet deliver in payback compared to a dollar spent in magazines or TV? Does a mix of media payback more? Which is the best mix?

    When we look directly at media's contribution to sales, we leapfrog the troubling lack of media comparability. Here's what ROI modeling tells us about how media work:

  3. SATIATION

    Satiation is why that first beer tastes best. In media, satiation is diminishing marginal returns to concentration.

    It shows up in two ways. Within a planning week, there is decreasing marginal response to frequency, (the earlier exposure has the greater effect). And there is decreasing marginal response to concentration, (the earlier GRP in any medium has the greater effect).

    The first supports reach, not frequency, the second argues for media-mix. Satiation also works within a medium. For example, dispersion across TV dayparts and venues produces a higher payback than concentration does.

    But evaluating media ROI is not that simple. Since the rate of response to a medium changes with dollars spent in that medium, the most effective media may be overspent and have the lowest ROI. MMA data (above) show that at current dollar allocations, other media now usually outperform television.

  4. ACCELERATION

    Acceleration is increasing returns to continuity. There is a higher marginal response to each added week of advertising. This is probably a systemic effect of prior weeks of advertising, which increase brand awareness and saliency, and make advertising and all other marketing efforts more productive.

  5. SYNERGY

Synergy is increasing returns to media convergence. It is the idea that concurrent brand messages to the same consumer in different media will produce a total effect, greater than the sum of the effects of the individual exposures. This is the so-called "Media Multiplier."

This is quite different from our current media-mix planning. We combine media so as to reduce overlap. Synergy planning would favor overlap.

It's appropriate to end our discussion of planning principles on a guarded note. There is always noise and conflicting goals.

Brand size effects may confound continuity effects, since larger brands can afford more weeks of advertising.

Media overlap can reduce the positive effect of continuity since overlapped schedules may result in fewer weeks of advertising. And attempting to cover the same consumer with multiple media will increase schedule frequency, at the cost of reach. So, synergy is not a clean win. But it's probably has greater importance in media-mix than we assign it now.

Those are the five principles of media planning and this was a talking paper. If you're ever invited to Burundi, Mr. President, now you can talk media.
