 * I see url/null being the source url for 404 errors.
    Is this caused by bots. 
   I checked with the host support. They dont see any 404 errors. Is this to be 
   worried about.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2F404-errors-in-redirection-plugin%2F%3Foutput_format%3Dmd&locale=en_US)

 * Yes, bots and spammers sniffing around URLs can certainly cause plenty of 404s,
   but this is normal, not something to be worried about.
 * I see you already posted over there, which is what I was going to suggest:
 * [https://wordpress.org/support/topic/404-errors-114/](https://wordpress.org/support/topic/404-errors-114/)
 * There’s not really a conflict, or anything to fix. I’m happy to provide advice
   if you have more questions, but this issue isn’t relevant to the code of Stop
   Spammers.
 * The 404s would still be occurring and the Redirection plugin would still be logging
   them even if you didn’t have Stop Spammers installed.

 * Thanks @bhadaway .
    I see that the main issue could be bots. As you suggested
   these 404 errors will still occur.
 * BTW, when I searched Google for url/null kind of error, I didn’t get any specific
   reason anywhere. But I see some right direction answers here. Thanks.

 * `null` is a programming term that generally means invalid, empty, undefined, 
   etc. It could be a spam bot or the Redirection plugin throwing that error in 
   the URL.
 * Generally speaking, malicious bots are often just searching URLs on a given website
   for vulnerabilities.
 * In a brute force manner, they’re checking thousands of potential URLs for a 200
   response code (meaning that it exists, which then leads to further penetration
   attempts), some that lead to known software exploits.
 * To cut down on 404 errors and bad bots taking up your server resources in general,
   you might add this plugin as an additional layer:

 * Thank @bhadaway for the input provided regarding bots and spam.
 * Regarding this discussion, I would like to ask
 * – whether the plugin mentioned above and yours, do they slow the site or wordpress
   dashboard or cause any reduction in organic traffic or any negative effect.
 * This is just to confirm so that I can use your plugin and other one with relief
   and be safe too from spammers.

 * Anything you add to a website will require resources and technically slow it 
   down.
 * Every website is different, and requires many kinds of optimization.
 * Concerning SEO and organic traffic, it is absolutely vital that your site loads
   quickly. The most important aspect of this is the quality of your host.
 * But, beyond that, you need to use best practices and optimize, optimize, optimize.
 * I highly recommend [https://wp-rocket.me/](https://wp-rocket.me/).
 * Whatever you ultimately do, do a before and after speed test at:

 * Good luck!
