By now, you've likely finished your holiday ads for social media — or perhaps you're putting the final touch on them. Either way, before you mark them done, do a quick check to make sure you’re reaching the right people.

If you’re like most businesses, the bulk of your holiday advertising budget is allocated to social media. 36 percent of small and medium companies are spending the majority of their budget on social media marketing, according to Reveal Mobile 2018 data. That’s nearly double what they pay for email marketing and five times the amount spent on search engine marketing.

It’s no small chunk of change either. Marketers are planning to spend 25 percent of their entire annual ad budget to target shoppers just during the Thanksgiving weekend, according to 2018 Nanigans data.

As a group, U.S. retailers are estimated to spend $6 billion during this four-day period from Black Friday to Cyber Monday, according to eMarketer estimates.

This holiday season, make sure to maximize your social media marketing dollars with this quick checklist.

What platform each generation prefers:

Are you targeting the right demographic on each social platform?

Baby boomers (ages 54 to 72) and the silent generation (ages 73 to 89): Baby Boomers prefer Facebook. There are nearly 32 million of them there!

That’s more than double the amount of Pinterest users and triplethe amount of Instagram users, according to 2018 eMarketer data. Plus, this year, 4.9 percent more 55- to 64-year-olds will join Facebook as will 6 percent more of those older than 65.

Generation X (ages 38 to 53): Facebook has the most Gen X users, followed by Instagram, found 2018 eMarketer data. This generation also spends more time on social media than any other generation. They spent nearly an hour more on social each week than Millennials, according to 2017 Nielsen data.

Millennials (ages 22 to 37): Millennials make up the lion’s share of Instagram users. There are 29.4 million users between just the ages of 25 and 34, according to 2018 eMarketer data.

However, millennials also like Snapchat. Those between the ages of 25 and 44 are the ones posting the most Snapchat Stories.

Gen Z (ages 6 to 21): There are nearly 4 million more teens on Snapchat than Instagram, according to 2018 eMarketer data. Teens also say it’s their favorite platform. But it’s not the most used.

Teens are using Instagram slightly more than Snapchat (85 percent checking it at least once a month compared to 84 percent looking at Snapchat). In the same vein, they cite Instagram as the place they want brands to contact and connect with them, according to a 2018 Piper Jaffray survey.

Avoid these most-hated tactics:

Once you know where your ads are going and whom you’re talking to, avoid these mistakes that no generation likes!

Too intrusive. 71 percent of people feel ads are more intrusive now than they used to be. If you have the urge to use a pop-up ad, resist it!

Advertise to the same person on every device and browser. It’s just too much! 42 percent of customers get overloaded, annoyed and often flag your ads when they see them everywhere they look. Instead, target the above generation on one (or maybe two) platforms.

Talking to strangers. 6 percent of shoppers tune out ads that come from brands that they don’t know or trust. Digital, especially social, ads are most effective when shown to people who have had at least one touchpoint with your company.
