Can I redirect my current wordpress blog to another domain/blog?

First thing you need to do is change the message on your 404 ....so that it can link people back to the main page.

Second thing check your permalinks as this can be a problem....have you recently moved things?

Third..did you buy spammed links to achieve your ranking? Google penguin and panda slapped out those practices and you get penalised harshly.

Fourth.. Are you adding regularly content that is being shared through social media as the new algorithm is counting this highly. You can improve this by syndicating with a service like http://tribepro.com?afid=7806ca0f-8feb-4ab4-ad50-79e228a4c5fc and link it to onlywire. works best with paid accounts but you use it free.

Lastly it is possible to redirect but that leaves you with more chances for bugs..and will slow down your site slightly and then greatly over time

You may want to check if google has penalized you also..because that is a large downgrade
