Welcome to the Q&A Forum

_Ideal solutions would be using Meta refresh tag but the problem is search engines are against this practice. So, as things stand, you have to use 301 redirect to fix this issue. I know there is a possibility that ranking may suffer a bit. So, here is the suggestion - What about making a bit changes in the body content to use this page as a landing page for a new product. I hope you just have to make some changes in the specification or the title will have a slight modification. If you can manage to do this, you will be in a win-win situation. Let us know what you think about this. _

CSS can definitely get in your way. Glad to hear that your rate has normalized now.

Hi Mike, The rel=canonical information is in the notices section. It's just a notice to say "hey, it's here, check and make sure you have it set up right". I took a look at your account and at first glance it does look OK (you don't have everything set to the home page and you're taking care of sort parameters). It's not a warning or error, just a notice, and all appears to be OK.

Mike, I agree with Alan that it is a serious issue that warrants some attention and planning. Worst case scenario, the expired pages return a 404 and you're missing a big opportunity to boost the rest of the site. Best case scenario, you 301 or link to category or cross-promotional pages to pass PR and visitors to the next most relevant page/category. The 301 would accomplish this, but like Alan said you run the risk of inadvertently creating redirect loops if there's no long-term planning for potentially thousands of pages and/or categories.
