They want to index the entire web. So if you want to stop Google from indexing your WordPress site, you need to be proactive about it.
Without taking the proper steps to block Google from your site, Google will invariably find your site, crawl it, and put it in the index. Here are a few ways in which you can do it…. To get started, the easiest way to keep Google away from your site is to use a core WordPress function. The robots.
The noindex tagas applied by WordPress, tells every single robot not to index your site. You could always manually add these two code snippets to your robots. The above method will stop Google and other search engines from indexing new pages of your site. But if Google already indexed your site, visitors will still be able to see your site in the search results for a period of time.
Google will eventually get around to removing your site from the index — but there will be a how to block web crawlers period where your site is still indexed and available.

Why Should I Block a Search Engine?
Jun 18, · In order for your website to be found by other people, search engine crawlers, also sometimes referred to as bots or spiders, will crawl your website looking for updated text and links to update their search indexes. How to Control search engine crawlers with a datingusaforall.com file. Website owners can instruct search engines on how they should crawl a website, by using a datingusaforall.com file. If you would like to place a block of your own for a bad bot or crawler, you can block them by IP in your Firewall app. In addition, customers that are on a paid plan can look at turning on Cloudflare’s Web Application Firewall (WAF) to further help reduce the threat of bad bots and crawlers that don’t follow good behavior guidelines.
I have a dozen websites hosted on a large VPS Linux webserver. Being lazy, I gradually upgraded my VPS server. And now, even that server is getting too small. It is Xmas time. So what else to do with my spare time but to optimize my server.
Once more! Ugly crawlers suspected In the past year, I refused to allocate any time to website upgrades — which often seem a waste of time and are a continuous source of new problems. I did not change anything significant on the server other than making it bigger. Recalling my past experience with excessive crawling activity , I suspected excessive crawlers, bots and spiders traffic again. Ok, roll up your sleeves, clean your guns, lock and load. Google by far and Bing to a minor extend have the most active web crawlers.
They can be over-active if you have a lot of content, like I have on my news sites. To make it worse, both of them do not respect the robots. You have to adjust their crawl rate manually, using the Google and the Bing web master utilities. To beat it all, Google resets its crawl rate every 3 months.
If I unleash Google with its default crawl settings on my sites, I get 7, crawl hits. Poor server…. Adjusting Google and Bing crawlers, is important for the type of sites I run, but it might not be for yours. The more content you have, and the more frequent it is updated, the heavier the crawler traffic will be.
Just check in the Bing and Google crawl statistics in the same webmaster tools. If there is no excess access say less than 1, per day , I would leave as is. If higher, slow down the crawlers. But, there are many more villains in town! I found an easy way to check for crawler activity using the Apache access log.
The access log registers all requests Apache the actual web server software receives. Analyzing the access log is like following the breadcrumbs to find the villains.
Or something like that. Locate the Apache access log on your server. I actually copy the file to my Mac, as it runs a Linux-clone anyways. With a single Linux command line, take all user agents, and sort them, based on occurrence: magic!! Beware, these are not all crawlers, as the data is intermixed with actual human user traffic and other useful traffic..
That is roughly x per hour. On the kill list, you go! The first port of call, is to limit crawler access using a robots. On my larger sites, I disallow ANY crawler, except a handful of useful ones. Check the robots. That will stop a good deal of traffic. Now, in my case, I had already tuned my robots. It sprinkles magical stardust on your website using heavenly redirects and surgical reconstructions of URLs etc.. Anyone who masters.
Which does not include me, by the way.. Edit it with a Linux-compatible text editor like Textwrangler.
One of the things you can do, with. It catches the server-hogging spiders at least those which were hogging MY server resources , bots, crawlers with a substring of their user. Thanks Emanuele Quinto! The previous method re-directed any request from the blocked spiders or crawlers to one page.. Using the spiders I wanted to block in the previous example, just add this code in your. While you are playing with the accesslog, try to catch the IP addresses of those malicious bots trying to hack into your website.
A simple hacking technique is poll your site for login or user registration pages. On my Drupal site, for instance, I can catch those bots trying to access the WordPress login page wp-login with this Linux command using the same test access log we used previously :. There is no reason why any human with honorable intentions would try to access the WordPress login on a Drupal site, except for hacking, so that gave me really suspicious IPs.
You can double check where the suspected IP addresses come from with a reversed IP tool. In my case I found multiple hack attempts coming from General information and location of No doubt then. I actually found loads of hacking attempts from After almost a decade of running my own VPS servers, I experienced there is not one recipe for web server tuning.
You should first look at using a proper cache on all your sites , ensure all plugins are working well , check what is causing system bottlenecks , tune the MySQL server ,.. BUT over the years, and talking with many webmasters, I have learned one thing: they often forget to look at the crawler traffic.
And with that, they forget that even the best tuned massive server will go on its knees if even one bot or crawler really misbehaves.. Previous post: « Monitor Twitter interactions on your mobile phone Next post: Block WordPress brute force attacks via xmlrpc. Super-helpful, thanks! I got the list like so:. Thanks again. I liked the php code in the redirect page. Useful for data gathering. Good post, but I would recommend against locking down your robots.
Respecting the settings in robots. Most traffic on the Internet is bots. By a gigantic margin. While it may seem on the face of it that most bots do not offer you any value in return for use of the resources you pay for, I think the situation is a bit more complex. Those bots serve to fuel useful services for users.
They make the Internet, overall, a helpful place to be. And they make you a part of it. If you start a war with them, they will win. They will change their bot to use a user-agent string identical to what the majority of users use, or have it select from a list of user agents that it is known you cannot block. They will route their requests through Tor, making it look like requests are coming from anywhere and everywhere.
At the end of the day, this is a situation where everyone relies upon everyone else to be understanding, tolerant, kind, and polite. This would mainly solve your bad traffic issues if you are blocking at the ISP level. Super helpful bro! Gave them a nice surprise in the. Excellent post. The free version shows you a list of the bots that are hitting your website — quite the wake-up call!
I tried eliminating it by adding known bot domains to GA, and even installed heat maps to track user actions.
But they only worked fine on smaller scales when I had enough time to watch all the videos. So bots have been a huge problem for me, yes.
Hi Alex, thanks.. You asked how else I protect my sites from bots. Well, I only use the tools I described in this article. Of course top 20 of those are bots. I can see their IP addresses an block them. Not on a technical side unfortunately but this is the only way i do it.
