Every now and then, someone asks a perfectly reasonable question: why does a personal blog still run ads?
For readers considerate enough to care—and considerate enough not to be using an ad blocker—I have nothing but respect. So here is the sincere answer: keeping ads on the site is partly sentiment, partly survival. Yes, ad revenue is involved. That means it has something to do with the blog staying alive. And in a roundabout way, it also has something to do with whether you can look at this little blog and feel that having your own is still worth believing in.
Then there is the even more curious reader, the one who asks more bluntly: if you insist on running ads, why are some of them so... low?
I respect that kind of honesty even more. But I am not especially good at answering that question directly, so it is easier to borrow the standard explanation:
1、网盟推广合作业务的匹配度与相关搜索技术关联，具体广告内容是结合代码所在网页内容来进行匹配得出，是系统自动匹配抓取的结果。
2、平时你在网上搜索过的历史记录会在电脑缓存中保存，广告出现时会读取你查询过的记录，然后自动推荐与您有关的广告。
This is also why people often ask things like:
a、为什么我在淘宝搜过的东西老出现在网页广告里？
b、为什么我在淘宝买过或者浏览过什么东西后，去浏览一些其他网站时，其网页上的广告总是类似我买过的东西？
If that sounds too technical, the simple version is this: the ads you see are closely related to the content of the page, but even more closely related to your own browsing habits.
And since this blog has never exactly been an age-restricted corner of the internet, the more likely explanation is... well.
Some questions really are better left unasked.
Take a look at what ads are showing up on your device. :)
Although there are ads on the blog, I have already configured the ad network settings: regular categories are allowed, while sensitive categories that could potentially cause harm have been blocked.
For the record: I am trying to be a decent person.
