keyword targeting
The keyword targeting we are talking about is actually Contextual in Google AdWords .
Keyword targeting implementation must have the following capabilities:
The ability to crawl web content and analyze it
When analyzing, it is necessary to take into account the influence of the structure of the page, html tags, links, etc., analyze the body of the page, and obtain the most appropriate keywords to describe the content expressed by the page. This is the bottleneck of whether keyword targeting is effective.
It should be noted that due to the high requirements for real-time and rapid analysis of pages, when there are enough pages, the system execution efficiency will be very low, so it must have the ability to crawl pages that may appear advertisements in advance.
Of course, fast analysis in real time is equally important.
The ability to set keywords for advertising in the advertising system
It needs to be able to ensure that operators can easily and quickly set keywords in the system (forward selection, reverse exclusion), and it is better if they can provide analysis and recommendation on the effect of keywords that have been placed before.
