Lookalike Audience มีประโยชน์อย่างไร

What are Facebook Lookalike Audiences?

Imagine being able to expand your audience reach beyond your existing customer base and connect with individuals who share similar characteristics, behaviours, and interests. That’s the magic of Facebook Lookalike Audiences

This innovative feature empowers advertisers by harnessing the power of data-driven insights to identify new audiences and tap potential customers who are similar to or look like your existing customers and are, therefore, more likely to engage with their content and be interested in their products and services. 


How Does Facebook Create Lookalike Audiences?

The success behind Lookalike Audiences lies in its intricate algorithms that analyse a wealth of data and dissect your current audience’s demographics, interests, online behaviours, and purchase history. With extensive insights drawn from this data, the algorithm is able to identify commonalities among your existing audience and search for users who match these traits, yet have not yet engaged with your brand. 

The result? A dynamic and accurate Lookalike Audience that possess similar attributes to your existing customer base, bringing you an untapped potential market through precise targeting. 


Benefits of Using Facebook Lookalike Audiences

Unlocking the potential of Lookalike Audiences can be a game-changer for your advertising strategy. The benefits are many and impactful:

Improved Targeting Accuracy

With this custom advertising tool, you can bid farewell to the guesswork associated with traditional targeting methods and find high-quality leads more efficiently. Lookalike Audiences empower you to reach individuals with similar characteristics and traits to your most engaged customers. This focused targeting increases the relevance of your ads and improves the changes of capturing the attention of potential customers.

Higher Conversion Rates

Engaging with individuals who already have similar interests and behaviours as your current customers are expected to improve conversion rates. This will bring more value to your advertising spending since you can also test out multiple audiences at once without needing to create several campaigns, saving you time and resources.

Increased Return on Investment (ROI)

Utilising Lookalike Audiences lowers acquisition costs, minimises ad spend wastage on uninterested audiences, and enables you to channel your resources to where they have the highest potential for conversion. With this type of strategy, you are able to nurture leads into first-time customers, and loyal patrons, which translates into a higher return on investment for your advertising campaigns.


How to Set Up Lookalike Audiences on Facebook?

Now that you have a clear understanding of the benefits of using Lookalike Audiences, let us go through this step-by-step guide to creating them:

Step 1: Select a Source Audience

Start by going to Audiences in your Ad Manager and choosing a source audience; this could be your current customer list, website visitors, or those who have engaged with your Facebook page. Your source audience can be based on a custom audience you already have. For example, a custom audience from customer lists can include those who have already shown an interest in your business or product outside of Facebook, and who have shared their email addresses and phone numbers. A custom audience from websites can be all visitors within a certain time period, or those who visited a specific product page or category page. Meanwhile, a custom audience from engagement are those who have viewed a video, followed your page, clicked on an ad, or responded “Interested” to an event. 

Your source audience can also be those whom you consider your qualified audience, drawn from your best customers based on lifetime value, transaction value, total order size, or engagement for a higher chance of conversion. The source audience can be as small as 100, but the recommended range is between 1,000 and 5,000 people so there is more data to work with.

Step 2: Choose Audience Size and Location

Determine the size of your Lookalike Audience and the geographical location or area you want to target depending on your goals. Facebook offers a sliding scale that allows you to adjust the audience size from 1 to 10. You can also choose a percentage range for how close you want your new audience to match your source audience. For optimal reach, it is best to strike a balance between having a broad reach or choosing a large percentage and hyper-targeting or choosing a small percentage.

Step 3: Create Your Lookalike Audience

Once you have the source audience and parameters in place, click on the “Create Audience” button and let Facebook’s algorithm get to work. It will analyse all relevant data and craft a Lookalike Audience tailored to your specifications. It can take 6 to 24 hours for your Lookalike Audience to be created, which will be refreshed every 3 to 7 days as long as the ads are active. You can create up to 500 Lookalike Audiences from a single source audience.

How to Optimise Lookalike Audiences on Facebook

Set Goal-specific Lookalike Audiences

Consider the goal of your campaign when creating your Lookalike Audience. If your goal is to increase awareness of your brand, a broader audience is more appropriate. However, if you want to target an audience that will likely have the interest or intent to purchase, then a smaller, more focused audience is more suitable.

Update Lookalike Audiences

Regularly check if the settings to your Lookalike Audiences are updated to keep the results relevant and effective. Updating them every 1 to 3 months is a good frequency to enable Facebook to create the accurate results that you need. 

Choose High-quality Sources

The results you get will vary depending on the quality of your source audience, so using your most engaged audience and best customers is your best bet. The closer in similarity your Lookalike Audience is to your source audience, the more effective your campaigns will be.

Use A/B Testing to Optimise Bids

Create multiple Lookalike Audiences based on a range of similarities to your source audience and initially test out the same ad on different Lookalike Audiences to see which will perform better. Once you know which ads work best for which audience, you can then increase your bids on those and use your ad spending more efficiently.

Use Other Parameters

Try enhancing your targeting by adding more parameters such as age, gender, and interests for your Lookalike Audience. You can also use other custom audiences such as website visitors in the last 30 days, those who have added things to their cart, or those who have signed up for your newsletter.


Lookalike Audience Mistakes to Avoid

Using Low-quality Sources

A broad or large source audience may sound like a good thing but not if many of them are unqualified, unengaged, uninterested, or unsuitable as your target audience. Taking the time to get high-quality sources would ensure that the results are most useful in executing campaigns effectively.

Neglecting to Update

This is related to the previous paragraph since it relates to the resources used in creating Lookalike Audiences. If the information provided is inaccurate or outdated, then the results from Facebook’s algorithm will also not be as useful or effective in achieving your campaign goals.

Having Insufficient Resources

Like with any advertising campaign, Lookalike Audiences may not bear the results you desire if the allotment of resources, such as knowledge, budget, and time, is insufficient. Ensure that you can invest adequately into the proper execution of this strategy, however, you also need to be careful that your resources do not go to waste in case it is not going as well as you planned.
