    I have an auto-blog that is basically a news aggregate. I had around 30,000 posts and about 5,000 tags which caused my plug-ins and server to begin having issues. I decided to just keep the posts from the last 45 days as well as tags that were used more than 5 times and delete the rest. I was able to delete what i needed and saw immediate improvement on the back end of my site. However, I then noticed traffic started slipping. This wasn't because of missing links however because I know from my tracking that the only links people are entering are news stories from within the last two weeks at the latest. I then read that when you delete web pages that are indexed G starts collecting 404 errors from spiders or the sitemap and does not like that.

    So, to the point, is there a way to automatically make all my 404 errors become 301 redirects to my homepage or a page that says the item they are looking for is expired ? There is a plug-in I've read about called "objection redirection" that sounds like it would do this automatically so 404 errors are never detected, however I can not find an active download link and their website is never up.

    Any suggestions?

    I'd be happy to enlighten you. It's really just setting up url-rewrites in a specific manner. If you can't google-find it, then just let me know.

    appleman - I have the small plan on hostgator and not enough money yet to upgrade. As soon as I can I will so I don't have to mess with this.

    tiero - I didn't know about url-rewrites. I googled it and will do some reading up. I will let you know if I still need help.

    rather than deleting your posts, use some good wp cache plugin and get a VPS. burst.net has cheap linux vps.

    but still if you decide to delete posts, you can use 404 SEO plugin or add following code to your theme's 404.php page.

    header("HTTP/1.1 301 Moved Permanently");
    header("Location: ".get_bloginfo('url'));
    • Thanks Thanks x 1

    leolion - went with your fix and just tossed that into the beginning of the 404.php It is sending 404's to the homepage which is perfect. I had a bunch of information in my 404.php because it displayed a custom page from the theme I was using. Do i need any information besides your code anymore since it will redirect everything to my homepage and no one will ever see the 404 page now?

    demoniox - Thanks for the code. any advantage of yours over just putting in the one part of leo's?
