PAGE STRUCTURE ADJUSTMENTS

Example implementations relate to page structure adjustments. The system may convert a binary tree representation of a plurality of content items to an initial page structure that includes a plurality of regions. The system may determine a region metric of each of the plurality of regions. The system may determine an item metric of each of the plurality of content items rendered on a respective region of the plurality of regions. The system may calculate an error associated with the initial page structure based on the region metric and the item metric for each of the plurality of regions. The system may generate a plurality of adjusted page structures and calculate an error associated with each adjusted page structure. The system may select an adjusted page structure from the plurality of adjusted page structures based on the selected adjusted page structure being associated with an error below a threshold.
