# TikTok Ads

> Connect your TikTok Ads account to Eyk, so your daily ad spend, clicks and impressions land in BigQuery next to your sales.

Connect TikTok Ads to Eyk to collect the daily results of your campaigns.

To send events from Eyk to TikTok Ads instead, see the [TikTok Ads destination](https://docs.eykdata.com/destinations/tiktok-ads.md).

## What Eyk builds from this data

Eyk copies the daily results of your campaigns into your own BigQuery project. BigQuery is the data warehouse Eyk sets up for you. All ad platforms land in the same tables, so you can compare them side by side.

| Table in BigQuery | What it holds |
| - | - |
| `fact_daily_ads` | Spend, impressions and clicks per ad per day, plus the orders and revenue the platform reports |
| `fact_attributions` | Your revenue per marketing channel, campaign and ad, for each attribution model, next to your ad spend |

In Canvas and Alvin AI, your ad spend shows up in **Attributions**, next to your sales. Connect a store platform too, so Eyk can calculate your return on ad spend, cost per acquisition and profit after ad spend.

The orders and revenue an ad platform reports can differ from your real sales. Eyk's attribution uses your own orders and tracking data instead. To open your BigQuery project, click **Google BigQuery** at the bottom of the Eyk sidebar.
