We recently changed our domain from http to https. When a user enters any URL on http, there is an global 301 redirect to the same page on https. I cannot find instructions about what to do with robots.txt. Now that https is the canonical version, should I block the http-Version with robots.txt? Strangely, I cannot find a single ressource about this...

Hi This subdomain has about 4'000 URLs indexed in Google, although it's blocked via robots.txt: https://www.google.com/search?safe=off&q=site%3Awww1.swisscom.ch&oq=site%3Awww1.swisscom.ch This has been the case for almost a year now, and it does not look like Google tends to respect the blocking in http://www1.swisscom.ch/robots.txt Any clues why this is or what I could do to resolve it? Thanks!

Hi. We had some URLs that were indexed in Google from a www1-subdomain. We have now disabled the URLs (returning a 404 - for other reasons we cannot do a redirect from www1 to www) and blocked via robots.txt. But the amount of indexed pages keeps increasing (for 2 weeks now). Unfortunately, I cannot install Webmaster Tools for this subdomain to tell Google to back off... Any ideas why this could be and whether it's normal? I can send you more domain infos by personal message if you want to have a look at it.

We have a site offering a voip app in 4 languages. Users are currently 302 redirected from the root page to /language subpages, depending on their browser language. Discussions about the sense of this aside: Is it correct to use a 302 redirect here or should users be 301 redirected to their respective languages? I don't find any guideline on this whatsoever...

I'm optimizing a pet supplies site (http://www.qualipet.ch/) and have a question about the best practice for expired product pages. We have thousands of products and hundreds of our offers just exist for a few months. Currently, when a product is no longer available, the site just returns a 404. Now I'm wondering what a better solution could be: 1. When a product disappears, a 301 redirect is established to the category page it in (i.e. leash would redirect to dog accessories). 2. After a product disappers, a customized 404 page appears, listing similar products (but the server returns a 404) I prefer solution 1, but am afraid that having hundreds of new redirects each month might look strange. But then again, returning lots of 404s to search engines is also not the best option. Do you know the best practice for large ecommerce sites where they have hundreds or even thousands of products that appear/disappear on a frequent basis? What should be done with those obsolete URLs?

hi we can get a valuable link with the desired anchor text from a news site. the destination url would be something like www.site.com/product. but in order to track conversions, our sales team would like to add an affiliate id to the url, so that it would look like this: www.site.com/product?sess_affiliate=ta how much link juice would a link to this affiliate url pass? would we be shooting our wad by linking to the ?sess-URL instead of the original URL?

Does anyone have experience on soft hyphenation and its effects on rankings? We are planning to use  ­ in our company blog to improve the layout. Currently, every word above 4 syllable will be soft hyphenated.
This seems to render okay in all browsers, but it might be a problem with IE9... In HTML 5, the "­" soft hyphenation seems to be replaced with the <wbr> Tag (http://www.w3schools.com/html5/tag_wbr.asp) and i don't find anything else about soft-hyphenation in the specs. Any experiences or opinions about this? Do you think it affects rankings if there are a lot of soft hyphens in the text? Does it still make sense to use ­ or would you switch to <wbr> already?
