生成HTML, CSS和JavaScript。编写生成器比编写解析器更容易，因此可以以不同的方式生成每个服务页面。这样就不能再使用缓存或静态内容了。

提供一个XML API来访问您的数据;以一种易于使用的方式。如果人们想要你的数据，他们就会得到，你不妨全力以赴。

通过这种方式，您可以以有效的方式提供功能子集，至少确保刮刮器不会消耗HTTP请求和大量带宽。

然后，您所要做的就是说服想要您的数据的人使用API。；）

快速解决这个问题的方法是设置一个陷阱。

Make a page that if it's opened a certain amount of times or even opened at all, will collect certain information like the IP and whatnot (you can also consider irregularities or patterns but this page shouldn't have to be opened at all). Make a link to this in your page that is hidden with CSS display:none; or left:-9999px; positon:absolute; try to place it in places that are less unlikely to be ignored like where your content falls under and not your footer as sometimes bots can choose to forget about certain parts of a page. In your robots.txt file set a whole bunch of disallow rules to pages you don't want friendly bots (LOL, like they have happy faces!) to gather information on and set this page as one of them. Now, If a friendly bot comes through it should ignore that page. Right but that still isn't good enough. Make a couple more of these pages or somehow re-route a page to accept differnt names. and then place more disallow rules to these trap pages in your robots.txt file alongside pages you want ignored. Collect the IP of these bots or anyone that enters into these pages, don't ban them but make a function to display noodled text in your content like random numbers, copyright notices, specific text strings, display scary pictures, basically anything to hinder your good content. You can also set links that point to a page which will take forever to load ie. in php you can use the sleep() function. This will fight the crawler back if it has some sort of detection to bypass pages that take way too long to load as some well written bots are set to process X amount of links at a time. If you have made specific text strings/sentences why not go to your favorite search engine and search for them, it might show you where your content is ending up.

无论如何，如果你从战术和创造性的角度思考，这可能是一个很好的起点。最好的办法就是学习机器人是如何工作的。

我还会考虑打乱一些ID或页面元素上的属性显示方式:

<a class="someclass" href="../xyz/abc" rel="nofollow" title="sometitle"> 

每次都会改变它的形式，因为一些机器人可能会在你的页面或目标元素中寻找特定的模式。

<a title="sometitle" href="../xyz/abc" rel="nofollow" class="someclass"> 

id="p-12802" > id="p-00392"

将你的内容放在验证码后面意味着机器人将很难访问你的内容。然而，人类会不方便，所以这可能是不可取的。

可能对初学者不利的事情:

IP封锁 大量使用ajax 检查引用请求头 需要登录

通常会有帮助的事情:

每周改变你的布局 robots . txt

有帮助但会让你的用户讨厌你的东西:

验证码
