Give examples to illustrate bidding advertisements, brand advertisements, channel advertisements and direct mail advertisements. Advantages and disadvantages.

Bidding advertisement: When users search with a keyword, the advertising content related to the keyword will appear on the search results page. Because keyword advertising has high positioning and better effect than general online advertising, it has developed rapidly.

Brand advertising: In order to improve brand awareness or open the market of products, many enterprises will advertise. We generally believe that advertising will bring very positive help to enterprises in this respect, while competitors will be negatively affected to a certain extent. But the truth may be far from it? Your advertisement is likely to become someone else's wedding dress, which is more likely to happen to small and medium-sized enterprises with insufficient budget. A large number of experiments show that in many cases, advertising will have a strong spillover effect. In other words, advertising will not only improve the sales of advertisers, but also greatly stimulate the sales of competitors' products. In some cases, this spillover effect is still very obvious, and the biggest beneficiary of advertising is not the advertiser itself, but the competitor. This spillover effect will occur in many advertising methods, including search advertising, mail marketing, TV advertising, Internet display advertising and so on.

Channel advertisement: A channel can view a detailed report on the effect of specific pages and advertising units. By specifying the channel of page or advertising unit combination, you can track the effect of banner advertisement and other banner advertisements at the top of the page, or compare the effect of motorcycle page and automobile page. You can also create channels to track each different domain so that you can see the source of the click. Although channels are used to track results and revenue, they will not affect revenue or advertising positioning. There are two channels to choose from: URL channel and custom channel.

Direct mail advertising: Direct mail advertising can locate customers more accurately than any advertising. Direct mail advertising can provide effective feedback information and reasonable reference for your schedule and price positioning, thus enhancing the adaptability and competitiveness of the market. Direct mail advertising can understand the customer's needs through the customer feedback information table, and can exclude customers who have no demand for the products introduced by the advertisement, thus reducing a lot of advertising costs. Enterprises can send product information directly to interested potential customers through direct mail advertising, and get the most effective information at the least cost.
