We saw a big opportunity in growing sales from adhesives, grouts and other tiling accessories, focussing on brand related searches (such as Mapei, Ardex, Schluter, etc), and separating the accessories from the tile products into different campaigns.
As the path to purchase is quite different for tiles compared to tiling accessories, this allowed us to use different bidding strategies. People looking for tiles may initially buy a sample order before coming back to place a full order, and hence value based autobidding is not appropriate in thise case.
However, for the tiling accessories, where people are likely to buy instantly, values based bidding would be appropriate. Having moved the tiling accessories into a different campaign, we could change to value based bidding , which has resulted in a significant increase in sales from the tiling accessories, maintaining a ROI over the target value of 500%
