In my COMM 464 lecture on Search Advertisement, my professor mentioned an interesting fact: “Search Engine Optimization is 6 times more effective than banner ads”. I did some research about this to find out why this was the case and stumbled upon an article that compared the effectiveness of search advertising and banner ads.
Based on an experiment conducted by a major bank in the US which used both banner and search ads, it was concluded that search advertising is more effective in driving sales compared to banner ads. This was because search advertising could be directly measure in its contribution to user’s purchase decision. Moreover, banner ads pose the attribution problem, where it is hard to identify which ads attributed to customers’ decision to buy business’ product.
However, it is important to note that banner ads does play a role in improving the purchase funnel process. Banner ads can be seen as being on the top of the funnel which drives customers down towards the bottom of the funnel, that is the search ads. Thus is because customers who are researching about whether they should open a bank account with them tends to take more time in the research process. During this stage, they are more likely to go through several webpages over time that also serve the bank’s banner ads. The constant exposure to the bank’s ads help drive customers’ curiosity to start clicking on their search ads which then leads to customer purchase.
Thus, although banner ads may not seem to give as much ROI as search ads, I believe that there is still value in having them for certain cases. Banner ads seems more helpful in increasing brand awareness, especially for products or services that would require strong consideration by customers (e.g. luxury products, opening bank accounts). For these type of businesses, it would not hurt to try using the combination of banner ads and search ads to help further optimize the effectiveness of their online advertisements.
