One of the major mistakes is to entask the wrong type of agency to handle your advertising needs like if you always deal with say Satchi & Satchi for your billboard advertising and print media which they are especially good and creative at what they do, don’t normally do a brilliant job at penetrating the New Age Media such as Blogs, Websites, Google Adsense or even those text messaging means and from my own experience in the field, they sub contract the job to another agency which does good at that medium but do not understand the need and locale restrictions of the business involved due to non disclosure agreements and such.
I am voted the worst blogger of all time outside the US for 3 years running by non conventional media ( Internet Based ) which my only competitor is only the likes of Perez Hilton and from my own experience in the media industry, having the wrong game plan cost dearly to the advertising budget.
Let’s just point into Electronic Means Advertising which covers the Internet, SMS – Text Messaging and E-Mails where there are over 1.5 billion users with nearly 3 billion having a cell phone. A very harsh way to blow your Google Adsense or Yahoo Ads budget is overbidding your keywords. Keywords are what weigh in the relevancy of the article or webpage to show the respective ads. Just like in this article, advertising keywords formed may be like Advertising which is not that expensive in normal times but if you add “Computers” “Web Hosting” and other hot keywords such as CHEAP, FREE and alike will drive up a standard bid from 20 cents to over $100 for webhosting where the Earnings Per Click or EPC is double or triple of the keyword bid. Major brands and events like thanksgiving will drive the cost higher and by placing the wrong sets and subsets of keywords will blow your $100,000 budget within a day!
Another mistake done is incorrect demographic mapping where you misplace your targets to the wrong zones, say if you only want California, specifically Los Angeles visitors for your Congress Election campaign but you fail to properly research the ISP and ZIP CODE GeoIP zoning will display all your ads all over the US or worst still, whole world and getting crappy traffic which are not converting.
Mass Mailing are a thing of the past and it will be gobbled up as fast as you send it out as fraud and heuristic programs built in place at mail servers will kill off and inform the other servers of your spam pattern. It is also ILLEGAL in many states and countries with criminal penalties of over BILLIONS OF DOLLARS in the case of a Facebook Spammer.
Going into the Print Edition, wrong type proofing, incorrect details and such costs money and reprints are time consuming and not to say more money especially due to a small error on a page of the magazine, you have to reprint the entire magazine which costs anything from US$1.20 onwards depending on your quantity and complexity. Typos and such must be compensated and those will eat into your budget too.
Whatever it is, plan for all contingencies as otherwise, you will cuss and swear at that tiny mistake which may even cost your business to belly up in these difficult times. I bear it all, as knowledge from events observed makes me mindful of those small tiny costly errors which we normally take it for granted.
