Custom Viewport
Selecting Custom Viewport in the Viewport dropdown will allow you to enter the exact pixel specification you need.
The following fields will appear with this option is selected :
Viewport Width - Pixels (up to 2560) the crawler will use for the viewport width. Enter only a whole number, no unit is required.
Viewport Height - Pixels (up to 1440) the crawler will use for the viewport height. Enter only a whole number, no unit is required.
Crawler Viewport Pixel Ratio/Scale Factor - The measure of how many physical pixels there are in a virtual inch of space on the device.
Crawl Using a Mobile Device and/or Touch Screen Device checkboxes - These provide you the option to choose the type of options used for the re-crawl needed after you adjust these settings.
The default values for the Viewport Width/Height and the Crawl Using a Mobile/Touch Screen checkboxes are taken from the last pre-set selection in the Viewport dropdown.
After adjusting the Viewport Width and/or Height, the site must be re-crawled for the data and viewports to be updated.
