Custom Error and page not found responses
-
When there is a 500 Internal Server Error, is it better to return an HTTP 500 response and custom error page from the requested URL, or is it better to return a 302 redirect? The redirect would send the browser to the custom error page, which would return the HTTP 500 result.
We tell Google not to index or follow our error pages, so if Google sees an error at a URL, we don't necessarily want Google to think that the URL should be ignored. That's why the alternative would be to redirect to a custom error page with it's own URL.
Similarly, what's the best approach if the response is a 404? Return HTTP 404 and custom 404 page from the requested URL, or redirect?
Thanks.

Just to add to Ryan's comments - if you had massive 500 issues, then you might theoretically argue that 301'ing would keep Google from crawling so many errors. At best, though, it's a band-aid, and maybe even a poor-fitting one. The better question is - why are those 500s occurring. Ultimately, they should be fixed, not patched.
Usually, Google isn't going to penalize a one-time 500 error or a short-term server problem. The only time I could see 301'ing is if you knew you had a major problem and couldn't fix it for a few days. The 301 (or possibly 302, in this case) could buffer you from crawl problems while you made the fixes. Obviously, that wouldn't be an ideal situation.

I have often though about this but have never really come to a answer.
If you 301 or 302 a page to a 404 error page and then return a 404, what are you telling the search engine. are you telling them that the erorr page does not exist, not the origianl page.I have always done just that, it was only recently that when wondering why goolge has not dropped pages from the index, that I had a good think about it. If you dont do anythiong and use the default ugly error page, it give a 404, rather than a 302 then a 404.
is this what gogole was talking about when they came up with soft 404 errors in WMT?
I did set up a test where i did both in 2 sites but i did not follow up on the test. -
The header response code chosen is important. I cannot think of any reason why you would choose to provide a 500 response code other then when your server naturally offers that response.
A 301 code should only be returned if you actually 301 the URL to the proper target. This code sends a message to search engines saying "hey, update the URL in your index to this new URL".
A 404 code should be returned if the content is no longer offered on your site and will not be offered. Actually, a 410 response "Gone" means the content is permanently gone and wont return. This tells search engines they should definitively remove the link. A 404 code tells search engines the content is not presently available. It may be a temporary issue which can later be resolved. When a search engine repeatedly finds a 404 error, they will then take action and remove the link.

Thanks for the replies.
I'm not sure I stated my question clearly. What I was wondering, was whether it is better to return status code 500 from the requested url, or status code 301 from the requested url. So in one case, the actual url content would be the error page, and in the other case it would redirect to the error page.
I'm not even sure if there is a difference, but if there is I'd like to learn more.
Thanks.

The best approach for a 404 error varies. If you know what the user was looking for and you have that content or similar content available, you should 301 redirect the user to the appropriate page on your site. For example, if you have a page on "Top 10 Christmas Gifts for 2010", if you delete that page you likely should perform a 301 redirect to your "Top 10 Christmas Gifts for 2011" page if it is available.
If you don't have a similar page available on your site, let the URL 404. Ensure your 404 page is helpful. It should have a basic "oh no, we lost your page" message along with your site's normal navigation and a search box. 404 errors are a natural part of the internet. In small numbers they are perfectly fine. Also, ensure your site's links are all valid. You can't control whether an external link leads to a 404 error but none of your internal links should cause a 404 error.
With respect to a 500 error, those are not common (at least compared to 404s). Something on your server is not configured correctly. You should have an error log and investigate the root cause of any 5xx errors. Find the source of the error and take action to fix it.

A 404 error means "not found". This is usually the page you get when you make a mistake spelling page name in a site, or if the page is deleted or moved. The problem is that the standard 404 page is ugly and unhelpful.
Many people have figured out that if you use a custom 404 page you can present a much more helpful page to you visitors. Others have taken it a step further and made that custom page a redirect to the home page, so that any links (and PR) pointing to pages that have been deleted (or misspelled) will be passed on to the website.
Hope this helps

My last site crawl shows over 700 404 errors all with void(0 added to the ends of my posts/pages.
Hello, My last site crawl shows over 700 404 errors all with void(0 added to the ends of my posts/pages. I have contacted my theme company but not sure what could have done this. Any ideas? The original posts/pages are still correct and working it just looks like it did duplicates and added void(0 to the end of each post/page. Questions: There is no way to undo this correct? Do I have to do a redirect on each of these? Will this hurt my rankings and domain authority? Any suggestions would be appreciated. Thanks, Wade

Responsive Content
At the moment we are thinking about switching to another CMS. We are discussing the use of responsive content.Our developer states that the technique uses hidden content. That is sort of cloaking. At the moment I'm searching for good information or tests with this technique but I can't find anything solid. Do you have some experience with responsive content and is it cloaking? Referring to good articles is also a plus. Looking forward to your answers!

Why is page still indexing?
Hi all, I have a few pages that - despite having a robots meta tag and no follow, no index, they are showing up in Google SERPs. In troubleshooting this with my team, it was brought up that another page could be linking to these pages and causing this. Is that plausible? How could I confirm that? Thanks,

Where is the best place for Landing Pages to reside on the Home Page?
On this site http://www.austintenantadvisors.com/ I have my main landing pages listed in the navigation under "Types". The reason why I did this is because I am not sure where to insert those on the home page where it does not look spammy to Google and looks natural for users. Obviously they need to appear somewhere on the home page for Google to be able to continue crawling and indexing them. Any thoughts or suggestions would be appreciated.
