The growth of telemarketing has made it increasingly important to quantify commercial radio's ability to deliver effective response and also to determine how to exploit that response most efficiently.
The objectives
The research into the use of direct response by radio advertisers set out to achieve the following:-
The increase in telephone buying has been
quite marked across many sectors as the following chart shows. At the same time the
consumer's awareness of special numbers, particularly 0800 numbers, has increased.

The research was conducted over a 3 week period from 6.00am to midnight.
The stations were:-
LOCAL
NATIONAL
The advertisements were monitored and those with BT direct response numbers noted with their times of transmission. The spots employing those phone numbers were matched to RAJAR Audience Data and passed to BT to extract the appropriate telephone response from BT's billing records*.

The final clean data set contained details on 4,248 direct response radio advertisements for a total of 71 different advertisers.
Response rates were monitored 5 minutes before and then after the advertisement was aired.
Response rate percentages were calculated by dividing the number of calls by the radio audience size.
Response indices compare specific response rates with the average response rate.
Whilst there can be no direct comparison with earlier surveys, as the samples were so different, the results showed that 64% of the advertisements during the period included a telephone number, which is considerably higher than had been assumed. Of these, 20%, employed a BT special number and were included in this research.

The consumer's awareness of freephone numbers is reflected in the higher response efficiency of 0800 numbers compared to other numbers.


From the following chart we can see quite clearly that the advertisements achieving the highest response far outstripped the average. This underlines the need to create direct response advertising that is focused on generating response with the creative treatment embracing this focus.
The results showed that ten second commercials achieve the highest response rate. These are used as a call to action after a longer informative spot earlier in the break. This also explains the comparative under performance of the 60 second spot, which is often use in conjunction with 10 second spots.

By looking at the chart below we can see that calls came in very quickly after the advertisement was broadcast and that the background level of calls received a boost only during the 5 minute period immediately after the spot. This rapid response time demonstrates radio's immediacy particularly when compared to television where the peak response time is 15 minutes after the broadcast time.

The need for efficient call handling facilities to cope with these fluctuations is vital and service performance can be enhanced with the introduction of IVR for certain applications. This was demonstrated by the results of recent research into IVR in a financial services test situation.

With consumer expectations increasing all the time, generating response that is not handled effectively can be counter productive. The effect on the brand or company image by consumer intolerance to poor call handling could provide opportunities for competitors. This message seems to have been understood by most advertisers in that nearly 84% of all calls were answered while only 16% failed to be answered (ineffective).
| Effective responses | 59,972 | 83.7% |
| Ineffective responses | 11,661 | 16.3% |
| Total responses | 71,633 | 100% |
If you remove the 10 radio advertisements with the worst percentage of ineffective calls;
Timing as much as frequency can be a critical factor in achieving effective response. The charts show that whilst most DR advertising is carried out in morning airtime the most response efficient time of day is early evening.
There is obviously a trade-off between audience size and efficiency. Advertisements rotated evenly throughout the day would seem to benefit from increasing effectiveness as the audience diminishes.


The charts showing efficiency by time of day imply that the best strategy would involve building brand and establishing an offer through the day and achieving response by spreading the campaign into the evening when the listener is more able to respond. This efficiency boost also applies to the weekend where the listener obviously has a greater opportunity to respond.


Many radio campaigns are part of a multi-media approach. As can be seen from the chart, previously televised campaigns have enhanced the response rates, however, part of this success may be due to television advertising being more likely to be undertaken by better known companies, thus increasing the confidence factor vital to direct response.

The frequency of repeat has a direct effect on the performance of the advertising. Repeats within 30 minutes to one hour show a marked difference to the rest.

When comparing one sector with another is it evident that some fare better than others. There are probably two factors that contribute to this: one is the increasing use of the telephone in a particular sector i.e. financial services; and the other is confidence which rises with the simplicity of the proposition such as the purchase of specific products like replacement windows.


Direct Response Radio is an effective marketing tool with enormous future potential.
Consumer confidence in the sector has grown in tandem with the increase in use of direct response numbers by advertisers.
The research has shown that it is important to plan direct response radio with care, to maximise the potential of the medium.
