Facebook advertising, when done correctly, can be a major asset to your marketing efforts. Facebook offers businesses a wide variety of advertising options to choose from, and with a network of billions of users, it provides the potential to reach tons of prospects.

However, there are a lot of moving parts that go into creating and maintaining successful Facebook advertising campaigns. If you’re not familiar with the ins and outs of the platform, it’s possible to fall into some pretty common traps. Here are some of the mistakes that I see businesses making time and again on the platform, and what you can do to avoid them.

1. Setting Wishy-Washy Goals

Facebook advertising is a single tactic within your broader marketing strategy. But that doesn’t mean you can be less-than-intentional about the choices you make when designing your campaigns.

It’s not enough to just create posts promoting your business and hope that some generic good will come of it. You need to set specific goals for each and every advertising campaign you undertake. If you’re promoting the launch of a new product, set a goal to sell X number of units. If your campaign is designed to drive traffic to your website, set a goal to increase CTR by X percentage points.

By starting with a clear goal in mind, your messaging within the campaign will be stronger and more targeted. Plus, you’ll know which metrics you should be keeping an eye on and will know exactly how you’ll define success at the end of the campaign.

2. Selecting the Incorrect Ad Type

Once you’ve set goals for your campaign, it’s time to select the type of ad you want to run. Facebook offers businesses a wide variety of choices, and the various ad types can help you achieve all sorts of goals—from greater exposure for your brand to more conversions to facilitating offer claims.

Fortunately, Facebook makes it easy for marketers to determine what each ad is designed to do. Don’t try to get creative or reinvent the wheel in this step; go with the ad type that Facebook says best aligns with your goals.

3. Sticking to Only One Medium

If you’ve ever sat on Facebook and scrolled through your newsfeed, you know how easy it is for that content to simply become a blur. That’s why you need to do something unique to stand out from the personal posts, articles, and other ads filling up users’ feeds.

Facebook suggests that you keep text to a minimum on your images (ideally less than 20 percent). Include images that are bright, arresting, and are aligned with your brand’s tone. Go beyond still images and think about including video content.

But most importantly, mix things up. Even if you’re creating fascinating, engaging video ads, they’ll begin to feel stale after a while if that’s all you ever do. Mix up your media in order to keep viewers on their toes and eager to see what comes next from you.

4. Targeting Improperly

Facebook advertising targeting allows you to identify the desired audience for your ads. This keeps you from wasting your ad spend on people who would never realistically be interested in your business, but proper targeting is a tricky balancing act.

Make your audience too narrow, and Facebook will be unable to deliver your ad. However, make your audience too broad, and there will be lots of people who are not viable prospects seeing your ads.

The other mistake that marketers make is targeting the wrong audience. You might think you understand who wants to see your advertising, but unless you’re using your existing customers as a guide, you could be making some critical targeting mistakes and aiming your ad spend at the wrong group.

Take the time to analyze the demographics and actions of your current audience. You can even go so far as to send your existing customers a survey, asking them about their profile and lifestyle. Facebook even provides the option for you to create lookalike audiences for your advertising. By uploading a list of your existing customers, Facebook can then analyze that group for common attributes and target similar audiences.

5. Duplicating Efforts

Facebook is great at identifying their users who are most likely to want to see your advertising. Unfortunately, that sometimes means that people who are already familiar with your brand and who have converted on their own become the target of your Facebook advertising.

This is, of course, a waste of your time and budget. If they’ve already signed up for your newsletter, there’s no need to advertise said newsletter to them again! This is where the use of custom audiences comes in. Pull a list of all of your prospects or customers who have already taken the action you’re hoping to drive with the advertising and create a custom audience that excludes these people from seeing your ads. Not only does this save you money, it also keeps you from annoying those who have already said yes to your brand.

6. Letting Ads Go Stale

Even the best of Facebook ads begin to lose their luster after a few weeks. Users scroll past the same images and type time and again, and they eventually begin to gloss over the content. That’s why it’s critical for marketers to keep refreshing their ads on the platform. Changing up images, altering the text, and otherwise making the content appear fresh and new to the viewers is the way to get your brand noticed all over again.

7. Forgetting About Facebook Pixel

Facebook Pixel is a line of code that you insert into your website in order to track customer behavior on your website that happens as a result of your advertising efforts. This provides you with measurable data, so that you know if your ads achieved the desired results. This data can also help to inform your future marketing efforts. When you understand what was successful and what didn’t work so well in a given campaign, you can make changes to amplify the successes and pivot from the failures in the future.

There are a lot of moving parts for marketers to wrap their heads around when it comes to Facebook advertising. Understanding some of the most common mistakes businesses make can help you get more bang for your advertising buck and create content that stands out in a crowded newsfeed.
