Displays unbeatable information to site visitors arriving at a non-existant page (from a bad link). Major SEO with Google AJAX, Google 404 Helper, Re
The goal of this plugin is to boost your sites SEO by telling search engines to ignore your error pages, with the focus on human users to increase people staying on your site and being able to find what they were originally looking for on your site. Because I am obsessed with fast web pages, many various speed/efficiency improvements are also on the horizon.
Another feature that I am using with beta versions of this plugin, is tracking information for you to go over at your leisure, to fix recurring problems. The information is collected is the requested url that wasnt found, the referring url that contains the invalid link.
The reason I didnt include it in this release is because for sites like AskApache with a very high volume of traffic (and thus 404 requests) this feature can create a bottleneck and slow down or freeze a blog if thousands of 404 errors are being requested and saved to the database. This could also very quickly be used by malicious entities as a Denial of Service attack. So I am figuring out and putting into place limits.. like once a specific requested url resulting in a not found error has been requested 100x in a day, an email is sent to the blog administrator. But to prevent Email DoS and similar problems with the number and interval of emails allowed by your email provider other considerations on limits need to be examined.
FAST! CACHE! SPEED!
One other big improvement or feature-add is to show the admin a list of error urls and allow the admin to specify the correct url that the error url should point to. Then using mod_rewrite rules automatically generated by the plugin and added to .htaccess these error urls will 301 redirect to the correct urls, boosting your SEO further and also helping your visitors. A big difference between this method and other redirection plugins is that it will use mod_rewrite, I would really like to avoid using php to redirect or rewrite to other urls, as this method has a HUGE downside in terms of your site and servers speed, bandwidth usage, CPU/Memory usage, Disk Input/Output (writes/reads), security issues, Database Usage, among other problems.

Anyone smart enough to find and use this plugin deserves to earn a little income too, so I am working on integrating AdSense into the Search Results. Currently this is very new and not enabled or allowed by Google in certain circumstances and just isnt a feature yet of the Google AJAX API. At the very least I am going to add a custom search engine results for your site that will allow you to display relevant ads, but I am still waiting for some clarification from my Google Homeslices on whether we can use the AJAX API to display ADS on 404 error pages automatically based on the requested url or if that violates the Google TOS, which is something I would never condone or even get close to violating. If not then we will have to settle for no ADS being displayed automatically and only being displayed if the user actually types something in the search box. So go get your AdSense account (free) and also sign up for a Google CSE (custom search engine) as soon as possible.
