Does anybody know if there's any complementary product available which automatically sets the bid prices if they change and adjusts position settings based on user-given rules?
If u have more than 200 conversion in a month, google is giving convertion adjustment tools, which is by far the best..as google itself will adjust your bids based on your set criteria and targets However, if you are new, lots of commercial products available..but it costs a lot which are good..just search for converions adjustment, bid tool , bid tool adwords etc
