By default Optimizer displays your Site Title as your Text Logo, you can customize the look of this text logo by going to Appearance > Customize > Header > Site Title & Logo > Text
In Optimizer, you can either upload an image as a logo or write your company name as text and display it as your logo. To add a logo to your Header simply go to Customize > Header > Site Title & Logo and click the “Image” tab and then click “Select Image” button to upload your logo image. When you do that, the Site title that was displayed by default will be replaced by the logo image.
You can align the logo to center, left or right from the “Site Title / Logo Position”.
Tip: If you dont have a logo, you can easily make one free from: logomakr.com
