Running online ads has become a crucial part of business growth. Platforms like Facebook Ads and Google Ads allow businesses to reach their ideal customers, generate leads, and boost sales like never before. Yet, many businesses in Tanzania and beyond are still losing money on ads because of simple, avoidable mistakes.

If you have ever spent money boosting posts or running Google campaigns without seeing results, you’re not alone.

This article highlights the top mistakes businesses make with Facebook and Google Ads, why they happen, and actionable tips to fix them for better results and higher return on investment (ROI).

1. Not Having Clear Goals Before Running Ads

One of the biggest mistakes businesses make with Facebook and Google Ads is launching campaigns without clear objectives.

Are you trying to:

Increase website traffic?
Generate leads?
Get WhatsApp inquiries?
Boost brand awareness?
Drive sales?

When you don’t define your goal, your ads lack direction.

Why This Is a Problem
Both Facebook (now under Meta Platforms) and Google use campaign objectives to optimize your ads. If you choose the wrong objective, the platform will show your ad to the wrong audience.

For example:

Choosing “Engagement” when you want sales
Choosing “Traffic” when you want conversions

How to Fix It
Before creating any ad:

Define one clear goal.
Choose the campaign objective that matches that goal.
Measure success based on that objective.

2. Targeting Everyone Instead of a Specific Audience

Another common mistake is trying to reach “everyone.”

Business owners often think:

“The more people who see my ad, the better.”

That is not true.

Why Broad Targeting Fails
If you sell baby products, advertising to people aged 18–60 without narrowing down to parents wastes your budget.

With Facebook Ads targeting options, you can:

Target by age
Target by location
Target by interests
Target by behavior
Create custom audiences

With Google Ads, you can:

Target specific keywords
Target specific search intent
Target by demographics
Use remarketing

How to Fix It

Define your ideal customer profile.
Narrow down your audience.
Use custom and lookalike audiences.
Test different audience segments.

Remember: A smaller, relevant audience performs better than a large, random one.

3. Boosting Posts Instead of Using Ads Manager

Many businesses rely only on the “Boost Post” button on Facebook.

While boosting is simple, it is very limited.

Why Boosting Is a Mistake
Boosting:

Offers limited targeting
Gives limited optimization options
Does not allow advanced tracking
Often leads to poor conversion results

Using Facebook Ads Manager gives you:

Advanced targeting
A/B testing
Pixel tracking
Conversion optimization

How to Fix It
Stop relying only on boosting. Learn how to use Facebook Ads Manager properly. It may look complex at first, but it gives you full control over your advertising strategy.

4. Ignoring the Power of Keywords in Google Ads

When using Google Ads, keywords are everything.

Many businesses:

Choose very broad keywords
Ignore negative keywords
Don’t research search intent

For example:
If you sell “office chairs in Dar es Salaam” but bid on the keyword “chairs,” your ad may appear for people searching for dining chairs, plastic chairs, or even chair repair.

That means wasted money.

How to Fix It

Use specific long-tail keywords (e.g., “ergonomic office chairs in Dar es Salaam”).
Add negative keywords.
Use keyword research tools.
Match your ad copy to search intent.

The more specific your keyword strategy, the better your results.

5. Poor Ad Copy and Weak Messaging

Even with perfect targeting, bad ad copy can ruin your campaign.

Common mistakes include:

Being too vague
Talking only about the company
No clear call-to-action (CTA)
Too much text
No emotional appeal

Example of Weak Ad Copy

“We are the best digital marketing company. Contact us.”

This does not explain:

The problem you solve
The benefit to the customer
Why they should act now

How to Fix It
Good ad copy should:

Focus on the customer
Address a problem
Offer a solution
Include a strong CTA
Highlight benefits, not just features

For example:

“Struggling to get leads? Our digital marketing strategies help Tanzanian businesses generate qualified leads in 30 days. Book a free consultation today.”

That is clear, benefit-driven, and action-oriented.

6. Not Installing Tracking Tools (Pixel & Conversion Tracking)

Running ads without tracking is like driving at night without headlights.

Many businesses:

Don’t install the Facebook Pixel
Don’t set up Google conversion tracking
Don’t measure ROI properly

Without tracking, you cannot:

See which ads are converting
Retarget website visitors
Optimize for sales

Why This Is Critical
Both Facebook and Google optimize ads based on data. If you don’t give them data, they cannot improve your performance.

How to Fix It

Install the Facebook Pixel on your website.
Set up Google Ads conversion tracking.
Track purchases, form submissions, and calls.
Monitor results weekly.

7. Sending Traffic to a Poor Landing Page

Many businesses spend money on ads but ignore where users land.

Common landing page mistakes:

Slow website speed
No clear call-to-action
Too much information
Not mobile-friendly
No trust signals

If your landing page is weak, your ad performance will suffer.

Why Landing Pages Matter
Even the best Facebook or Google ad cannot fix a bad website.

In Tanzania especially, most users browse on mobile. If your page is not optimized for mobile, you lose potential customers instantly.

How to Fix It

Keep landing pages simple.
Use one clear CTA.
Make it mobile-friendly.
Add testimonials.
Ensure fast loading speed.

8. Not Testing Different Ads (No A/B Testing)

Another major mistake is running one ad and expecting perfect results.

Digital advertising is about testing.

You should test:

Different headlines
Different images
Different audiences
Different CTAs

Why Testing Is Important
What works for one business may not work for another. What works this month may not work next month.

How to Fix It
Run multiple variations:

Version A vs Version B
Different creatives
Different audience groups

Then analyze performance and scale the winning ad.

9. Giving Up Too Soon

Some businesses run ads for 3 days, see no sales, and stop.

Digital ads need:

Time to optimize
Data to learn
Budget for testing

Both Facebook and Google have learning phases where the algorithm adjusts delivery.

How to Fix It

Give your ads enough time.
Allow data collection.
Optimize based on performance.
Avoid constant changes during the learning phase.

Patience and strategy bring better long-term results.

10. Focusing Only on Sales and Ignoring Brand Awareness

Not every ad should push for immediate sales.

Many businesses ignore:

Brand awareness campaigns
Video view campaigns
Engagement campaigns

Sometimes customers need to:

See your brand
Trust your brand
Then buy

How to Fix It
Create a marketing funnel:

Top of funnel: Awareness
Middle of funnel: Engagement
Bottom of funnel: Conversion

This strategy improves long-term profitability.

How to Succeed with Facebook and Google Ads

Running successful Facebook Ads and Google Ads is not about luck—it is about strategy.

To avoid wasting money:

Set clear goals.
Target the right audience.
Use proper tracking.
Write strong ad copy.
Optimize landing pages.
Test consistently.
Be patient.

Businesses that treat digital advertising as a long-term investment see better results than those looking for instant miracles.

If you are serious about growing your business online, take time to learn how these platforms work; or work with a professional who understands digital advertising strategy.

Done correctly, Facebook and Google Ads can:

Increase brand visibility
Generate qualified leads
Boost sales
Scale your business

Avoid these common mistakes, apply the right strategy, and your ads can move from being an expense to becoming a powerful revenue engine for your business.
