For example, using an account-based marketing tool like Sixth Sense gives us insights into only a small portion of our audience. And while we can be confident that the matched customers fit our ideal customer profile, what about the other 90% of visitors who aren't matched? Lytx makes it easy to leverage the data you do have to uncover customers who behave similarly. Building on our previous example, we can take the 10% of our audience we know and find customers who resemble the ideal profile from that group. We do this using Lytx Lookalike Modeling, a fully automated and highly configurable engine that surfaces the insights you need to engage your audience. To get started, navigate to Lookalike Models under the Using Profiles section in the main menu and choose Create New Model. From there, select the audience you want to analyze, in this case, customers without Sixth Sense data. Next, choose the audience you'd like to compare them to. Finally, Lytx will analyze all available data, including behavioral and interest signals, to determine how closely the customers in your source audience resemble those in your target audience. Next, we'll activate our model at the top of the screen. This will start the analysis process. Finally, we can choose to create a new audience using this model. It will take you directly to the audience builder with an initial definition in place. Customize it to your liking and sync the resulting audience. It's that easy. Under the hood, the result is a score between 0 and 1, 0 being a very low level of similarity, while 1 represents a high level of similarity. These scores exist independently on every user profile. #### Subtitles (WebVTT) ```webvtt WEBVTT 1 00:00:00.000 --> 00:00:19.700 As marketers, we know that data isn't always readily available. 2 00:00:19.700 --> 00:00:24.040 For example, using an account-based marketing tool like Sixth Sense gives us insights into 3 00:00:24.040 --> 00:00:26.740 only a small portion of our audience. 4 00:00:26.740 --> 00:00:31.220 And while we can be confident that the matched customers fit our ideal customer profile, 5 00:00:31.220 --> 00:00:35.900 what about the other 90% of visitors who aren't matched? 6 00:00:35.900 --> 00:00:41.500 Lytx makes it easy to leverage the data you do have to uncover customers who behave similarly. 7 00:00:41.500 --> 00:00:46.220 Building on our previous example, we can take the 10% of our audience we know and find customers 8 00:00:46.220 --> 00:00:49.300 who resemble the ideal profile from that group. 9 00:00:49.300 --> 00:00:53.840 We do this using Lytx Lookalike Modeling, a fully automated and highly configurable 10 00:00:53.840 --> 00:00:58.080 engine that surfaces the insights you need to engage your audience. 11 00:00:58.080 --> 00:01:02.520 To get started, navigate to Lookalike Models under the Using Profiles section in the main 12 00:01:02.520 --> 00:01:11.560 menu and choose Create New Model. 13 00:01:11.560 --> 00:01:16.200 From there, select the audience you want to analyze, in this case, customers without Sixth 14 00:01:16.200 --> 00:01:19.200 Sense data. 15 00:01:19.200 --> 00:01:26.240 Next, choose the audience you'd like to compare them to. 16 00:01:26.240 --> 00:01:33.520 Finally, Lytx will analyze all available data, including behavioral and interest signals, 17 00:01:33.520 --> 00:01:37.240 to determine how closely the customers in your source audience resemble those in your 18 00:01:37.240 --> 00:01:38.480 target audience. 19 00:01:38.480 --> 00:01:42.040 Next, we'll activate our model at the top of the screen. 20 00:01:42.040 --> 00:01:44.120 This will start the analysis process. 21 00:01:44.120 --> 00:01:47.800 Finally, we can choose to create a new audience using this model. 22 00:01:47.800 --> 00:01:52.560 It will take you directly to the audience builder with an initial definition in place. 23 00:01:52.560 --> 00:01:55.480 Customize it to your liking and sync the resulting audience. 24 00:01:55.480 --> 00:01:57.520 It's that easy. 25 00:01:57.520 --> 00:02:03.680 Under the hood, the result is a score between 0 and 1, 0 being a very low level of similarity, 26 00:02:03.680 --> 00:02:06.680 while 1 represents a high level of similarity. 27 00:02:06.680 --> 00:02:09.800 These scores exist independently on every user profile. ``` ```transcript [00:00] As marketers, we know that data isn't always readily available.
