Ask any Las Vegas small business owner how to measure the success of an advertising campaign. The answer will almost always 'sales.'

According to Nielsen research, the media-element of a campaign that has the most significant effect on sales is reach. This is the number of different people exposed to the advertiser's message.

There are more ways than ever to advertise. But, which of those options has the largest reach among Clark County consumers?

Doug Schoen, an advertising professional with 35 years of experience, writes in Forbes: "You wouldn’t know it from all the media coverage focused on streaming video and streaming music, but radio actually has the most reach among American media consumers. 93% of adults listen to the radio each week as compared to 87% who watch TV, a substantive difference."

By April 15th next year, 885,929 residents in the Las Vegas area will file a tax return.  More than 53% of these returns will be completed by the taxpayer themselves, either by hand or with the help of an online provider like Turbotax.

Every season, Clark County small business owners who specialize in tax preparation services lose customers to the do-it-yourself options.  This year, 412,00 local consumers will spend $79,600,000 with tax professionals. But, based on the average cost of services, more than $91,000,000 will stay in the wallets of the DIY crowd.

To clawback this enormous amount of money from the DIY market, local tax services will need to advertise the valuable benefits of using a professional.

The best advertising option for tax professionals is on Las Vegas radio stations. Here's why.

Las Vegas small businesses that sell products or services to pet owners should sit up and take notice.  Local consumers will spend $465,000,000 this year on behalf of Fido and Fluffy. This amount has increased 323% since 1994, with no sign of letting up.

According to the American Pet Products Association, here's how local spending on furry companions breaks down:

• Food: $190,897,000
• Supplies/OTC Medicine: $102,432,000
• Vet Care: $116,400,000
• Live Pet Purchases: $13,968000
• Other Services: $41,904,000

The biggest month for sales of pet-related products and services in Las Vegas is, by far, December. That is when 10.5% of all annual spending happens in this category.

Las Vegas small business owners have depended on radio advertising to market their goods and services since 1941.  That's when the Laura Belle and her husband Maxwell Kelch put the first successful local radio station, KENO on the air.

Today, there are 35 radio stations that serve Clark County. Each provides a unique blend of music, information, and entertainment.  Some stations focus on politics or sports. Some play country music. Some play the hits. Some play classic rock. Some are on the AM dial. Some are on FM.

When KENO began broadcasting, there were no TV stations in Las Vegas. Those would come 13 years later. Also, there was no social media, YouTube, Sirius/XM, Pandora, Spotify, or smartphones. Each of those would be products of a new Millenium.

With an overabundance of advertising options now available to small business owners, does advertising on Las Vegas radio still make sense?  Here are five facts that serve to answer that question.

Las Vegas consumers are expected to spend $45.6 billion at retail this year, according to Nielsen. This means that every household, on average, will be paying out $55,451.

To capture a larger share of these dollars, local small business owners need to know the answer to two questions.

The first question is, where is this enormous amount of cash being spent?  The list below details the answer.

Some Clark County small business owners believe that local consumers have ditched their favorite Las Vegas radio stations in favor of music beamed to their cars from space. Is this true? 

The short answer is no. Here are the facts.

There are 1.6 registered vehicles in the Las Vegas area.  Nearly 44% of these cars and trucks are equipped to receive satellite radio from Sirius/XM. To use the service, however, drivers must pay between $10.99 and $20.99 per month.

According to Nielsen,  though, satellite radio has had no effect on the number of people who tune-in to Las Vegas radio stations each week.  For that matter, neither has Pandora, a streaming audio service that is also owned by Sirius/XM.

Last week, for instance, nearly 90% of all adult consumers tuned-in to a Las Vegas radio station. Only 17.2%, however, listened to Sirius/XM, which is the only remaining satellite service. 

Last week, according to Nielsen, 365,811 single, adult women tuned-in to a Las Vegas radio station.  This is 89% of every consumer who fits this description.

Why should Clark County small business owners take note of this demographic? A study by investment bank Morgan Stanley finds 41% of working-age women are single. That number is expected to increase to 45% over the next ten years.

The study, called 'Growth of the SHEconomy', indicates that single women outspend the average household in many retail categories. Remarkably, says, Erica Sweeney of MarketingDive, "Women purchase more than half of products traditionally considered 'male' including autos, home improvement products, and consumer electronics."

OMG! Did you just call the 1.5 million adult consumers who tuned-in to a Las Vegas station last week a 'nobody'?

If you did make that mistake, then you wouldn't be the first Las Vegas small business owner or media professional to do so. Even, Doug Schoen used to share that opinion. He came clean, however, in a Forbes article.

"You wouldn't know it from all the media coverage focused on streaming video and streaming music," writes Mr. Schoen, "but recent Nielsen data shows radio actually has the most reach among American media consumers. 93% of adults listen to the radio each week as compared to 87% who watch TV, a substantive difference."

This is true in Las Vegas, as well, where radio listeners far outnumber the people who watch local TV; read local newspapers; or stream audio sites like Pandora and Spotify; or log-on to social media sites like Facebook and Instagram.

It's the cycle of American business. During this country's history there have been more recessions than presidents, 47 vs. 45.  Unfortunately, some economists believe number 48 could start any day now.  

The textbook definition of a recession is a period of declining economic performance across an entire economy, frequently measured as two consecutive quarters. In other words: it's a time when most Las Vegas small business owners sell fewer of their goods and services.

There is one thing a recession is not.  It is not a time for local business owners to stop advertising.

One of the great marketing minds of all time, Henry Ford, once said, "The man who stops advertising to save money is like the man who stops the clock to save time."

There are many examples of companies that have proven Mr. Ford's observation to be accurate. The bowl of cereal you had this morning could be one example.

Based on information from the National Retail Foundation, Las Vegas consumers will be spending $55 million on Halloween this year. 

Typically, 80% of all Halloween shopping, according to the NRF, will occur between now and October 16.  The remaining dollars will be spent in the last 14 days leading up to the holiday.

Nearly 53% of consumers in Clark County are expected to participate in Halloween this year, each spending, on average, about $86.  This money will go towards the purchase of candy, decorations, costumes, pumpkins, and greeting cards.

Almost every type of small business in Las Vegas enjoys a taste of this spending. This includes hardware stores, convenience stores, craft stores, fabric stores, thrift stores, florists, card stores, consignment shops, haunted houses, home decor store, bakeries, and, of course, candy stores.

To claim a significant share of this Halloween cash will require local small business owners to advertise.  The key to successful advertising is reaching as many Halloween shoppers as possible over the next four weeks.
