Good point with the backlinks! Currently, both robots.txt files are open and google does not seem to have canonicalization problems so far. So it makes sense to leave it this way anyways... Thanks Thomas!

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...

Yes, I think the crucial point is that addressing googlebot wouldn't resolve the specific problem I have here.

I would have tried adressing googlebot otherwise. But to be honest, I wouldn't have expected a much different result than specifying all user agents. Googlebot should be part of that exclusion in any case.

100 points for you Martijn, thanks! I'm pretty sure you've found the problem and I'll go about fixing it. Gotta get used to having https used more frequently now...

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!

Maybe linking each blog post might be overdoing it. But link to your sales pages where it makes sense, i.e. where you specifically talk about the products/services you sell. Don't overoptimize your anchor text though. But smart internal linking can indeed improve authority of your linked-to pages.

My pleasure! Have a nice day as well:)

Yes, probably a good idea to use specific portfolio tags (like "portfolio cats", "portfolio dogs", etc.). That way it doesn't get mixed up with other content (unless you want it to, of course).

Then you could create a portfolio overview page where you link to your sub-topics.

Split the portfolio up into various topics? This seems better for usability as well. Tag the various portfolios by category and make it nice and browseable. Does that make sense?
