How To Stop Bad Bots (SpamBots) From Stealing Your Magento Store’s Bandwidth

Share

If you are amongst those Magento store owners who never look into access_log still notice that your Magento store is slow then there is serious rethinking to do. Internet is flooded with variety of bad bots who typically steal your bandwidth and make huge number of requests to your server. Your server starts serving the requests from bad bot and in return becomes very slow to genuine visitors/customers. You might say that i have perfect robots.txt file in place which is allowing only legitimate Magento directories to be crawled. You might have setup Crawl-delay properly so you are safe. Well, like is said you have some rethinking to do.
What are Bad Bots (SpamBots)?
Bad bots or spambots are computer generated programs who attacks your site to steal all your data. They can also do some specific tasks like email harvesting, content scraping or simply trying to index your pages in their less known search engines. Whatever the reason of their attack they are simply putting immense load on your server and consuming precious bandwidth.  If you are on a shared hosting your mighty suspension due to overuse although the actual traffic (customers/visitors) is pretty less.
How To Block Bad Bots (SpamBots)
The traditional way is the to setup rules in your robots.txt file to allow/disallow certain bots from crawling your site. Most of the decent bots (Google, Yahoo, MSN etc.) obey robots.txt directives when it comes to crawling. But, don’t expect the same from Bad Bots, they are thieves and they tend to ignore robots.txt so you have to device a different technique for them which i am listing below.

1. Set up crawl delay if you are experiencing load even from good bots. to do this you have to write the following lines in your robots.txt file situated at your root folder where Magento is installed.

# Crawlers Setup
User-agent: *
Crawl-delay: 10

# Disallow Internet Archiver Wayback Machine
User-agent: ia_archiver
Disallow: /

Note: Google don’t read crawl-delay so you have to explicitly set crawl rate in your Google Webmaster control panel.

2. Block bad bots (SpamBots) via .htaccess file: Whether bots like it or not but they have to obey .htaccess file for sure. We can write a huge list of known bad bots and keep on adding to the list by looking at your access_log. One’s which are attacking most should be checked via reverse proxy and if they are illegal bots just block them. add the following lines of code in your .htaccess file

# Start Bad Bot Prvention
