Emphasis on brand names should also be checked. Price figures should be analyzed. If price lines are involved either in the ad or in the merchandise line of which the advertised product is a part, you should consider them also. Check the effect of the length of broadcast ads. Check the size of print ads.
Size often has a bearing on response.
As a general rule, the larger the ad, the larger the response. Try to find the combinations which work best for your firm and merchandise. Note changes occurring over time You should never take a winning combination for granted. There is no single formula that will insure high response ads every time. Therefore, you should watch the ads of others to see what changes are occurring.
