Redirects (301/302) versus errors (404)
-
I am not able to convincingly decide between using redirects versus using 404 errors. People are giving varied opinions. Here are my cases
1. Coding errors - we put out a bad link
a. Some people are saying redirect to home page; the user at least has something to do PLUS more importantly it does NOT hurt your SEO ranking.
b. Counter - the page ain't there. Return 404
2. Product removed - link1 to product 1 was out there. We removed product1; so link1 is also gone. It is either lying in people's bookmarks, OR because of coding errors we left it hanging out at some places on our site.

To add to what George says....
Google often tries to crawl pages that don't exist - simply to make sure they aren't missing anything on your site. When a page is clearly broken, you want to communicate this to Google by serving a 404 (but you can make it a friendly 404)
Here's what Googler John Mueller has to say:
What about the funky URLs that are “clearly broken?” When our algorithms like your site, they may try to find more great content on it, for example by trying to discover new URLs in JavaScript. If we try those “URLs” and find a 404, that’s great and expected. We just don’t want to miss anything important (insert overly-attached Googlebot meme here)."
Google expects to find 404s on your site. When they don't find 404s for links that should be broken, this sends confusing signals and could cause crawl problems.
I recommend reading this entire article - it's one of the most helpful I've ever read on the subject: http://googlewebmastercentral.blogspot.ch/2011/05/do-404s-hurt-my-site.html
As for expired products - as George said it's best to 301 them, usually to a category level page.

I have similar issue, Recently Google blocked my blog for Google Adsense then after removing two to five articles, now they are online.
But now i get more 404 error for that page. I removed from the blog, I drafted them, in case if google not allowed the ads, i will re-publish it.
Now i have to remove the post link from the search results and from cPanel i can redirect to the home page
Their Page Authority is 25-30 respectively ! Plz advice me !

Richard and Moosa are right, use a friendly 404 page to help your users when they reach a page that can no longer be found. Simply redirecting them to the home page doesn't fix the issue of the missing page. Here's an old, but relevant, post on the subject: http://www.seomoz.org/blog/personalizing-your-404-error-pages.
For your second issue, if you've permanently moved to a new product page, you should certainly 301 redirect to not only pass on all the link juice from the old page, but also to provide the best user experience for your customers - they were looking for the product so give them the new improved page :).

Ok, here is the easiest way to understand this (As far as I think)!
- 404: This is the status code that browser give when the page on the website is not available.
- 302: This is the status code of the page if it is temporary redirected to some new page. This simply means that old page will not pass the link juice to the new page but when user reach to this URL will drive them to a new location.
- 301: This is the status code which does almost the same work as 302 but in that case old URL passes its link juice as well. This is commonly known as permanent redirection.
Websites usually should not use 404 as this disturbs the user experience of the page but upon requirement and keeping scenarios in mind use of 301 or 302 is always an intelligent approach.

Hi For 1: I would suggest a custom friendly 404 page. This means the user sees a page saying something like 'Sorry the product / page you were after no longer exists. Here are some useful options ( then list a handful of popular page links). You could even includes a site search or your tel number / email to contact. This means the user knows what has hppened, had somewhere useful to go but it returns a 404. For 2: If the page is being moved - use a 301 redirect on the existing page. If you are simply not selling that product anymore than do a 404 as above. In both cases monitor your GA and GWT for 404s and fix where applicable. All the best. Richard

How long should an old site redirecting to a new site remain activated on a server?
Once I switch a site to a new domain (with links to corresponding/relative pages), will I have to keep the old site live forever for those links to work, or how long should I wait before I inactivate the old site on our server?

How to split organic traffic for A/B testing
This might be a silly questions as I may be missing something completely obvious here, but we are completely new to A/B testing. Our site doesn't receive a phenomenal amount of traffic although we are looking to set up some A/B testing for our popular products. Is there a way to split organic traffic for a specific product page. I'm aware that we need to experiment which one performs better in Analytics but I'm unsure how to redirect 50% of the organic traffic.

Multiple websites for different service areas/business functions?
I'm wondering what the implications are for having multiple domains for different service areas of a company? I realize having multiple domains for one company can be troublesome because of the possibility of duplicate content, keyword cannibalization, and linkbuilding to multiple domains. But when the domains are for very different service offerings/unique business functions that each serve their own purpose (and have different positionings), is there a downside to having more than one domain? Any thoughts would be appreciated!

SEO strategy for UK / US websites
Hi, We currently have a UK-focused site on www.palmatin.com ; We're now targeting the North American market as well, but the contents of the site need to be different from UK. One option was to create another domain for the NA market but I assume it would be easier to rank with palmatin.com though. What would you suggest to do, if a company is targeting two different countries in the same language? thanks, jaan

Image with 100% width/height - bad ranking?
Hi, we have some articles like this: http://www.schicksal.com/Orakel/Freitag-13 The main image has a width of 100% and a height of 100%. Today, I've discovered that GWT Instant Preview has some troubles with rendering the page. We have CSS rules to deliver the image with the right dimensions. If a bot like google is not sending any screen height / width we assume the screen size is 2560x1440. Does this harm the ranking of the page? (Content starts below the fold/image) What is a "default" screen size for google? How do they determine if something is "above the fold"? Any tips or ideas? Best wishes, Georg.

Is it cloaking/hiding text if textual content is no longer accessible for mobile visitors on responsive webpages?
My company is implementing a responsive design for our website to better serve our mobile customers. However, when I reviewed the wireframes of the work our development company is doing, it became clear to me that, for many of our pages, large parts of the textual content on the page, and most of our sidebar links, would no longer be accessible to a visitor using a mobile device. The content will still be indexable, but hidden from users using media queries. There would be no access point for a user to view much of the content on the page that's making it rank. This is not my understanding of best practices around responsive design. My interpretation of Google's guidelines on responsive design is that all of the content is served to both users and search engines, but displayed in a more accessible way to a user depending on their mobile device. For example, Wikipedia pages have introductory content, but hide most of the detailed info in tabs. All of the information is still there and accessible to a user...but you don't have to scroll through as much to get to what you want. To me, what our development company is proposing fits the definition of cloaking and/or hiding text and links - we'd be making available different content to search engines than users, and it seems to me that there's considerable risk to their interpretation of responsive design. I'm wondering what other people in the Moz community think about this - and whether anyone out there has any experience to share about inaccessable content on responsive webpages, and the SEO impact of this. Thank you!
