Webmaster Trends Analyst at Google Switzerland. I work together with the web-search engineers and the webmaster-support team to help webmasters to make awesome content that search engines can understand and recommend.

I primarily post in the Google Webmaster Help forums (in English & German). You can also catch me on Google+, occasionally even in live hangouts :-).

comment When to tell Google Webmaster Tools that domain has moved
@dasickle Ah, yes, we just recently added a check for redirects before using the feature (well, at least for the homepage -- for the whole site we'd have to recrawl everything, which can take a lot of time). It sounds like we should have waited until you had it set :)

comment Should I include the current language code in <link rel=“alternate” hreflang=“” />?
The main reasons are that it makes it easier to reuse the same block of annotations on all pages of the set, as well as making sure that canonicalization issues don't cause unnecessary problems. For example, if /en.htm?sessionid=123 doesn't mention that /en.htm is the English version, we may assume that the "sessionid=123" part is important (but not confirmed by the other pages).

comment Google indexing pages with #! although we don't have any
I wouldn't recommend that: it would be cloaking and against Google's webmaster guidelines.

comment Moving from http to https - Google webmaster tools | Bing webmaster tools
Google Webmaster Tools treats https:// and http:// as separate sites; you should definitely add them separately if you use them both (or are migrating from one to the other). You should also update the sitemap file to point to the new URLs.

comment Indexing internationalized pages
FWIW we currently also only index one language version per URL, so if you serve different language content on the same URL, Google would only index one of those versions (whichever is served by default, probably). Use separate URLs per langauge & region! support.google.com/webmasters/answer/189077?hl=en has more on how hreflang works.

comment New Google SEO benefit with SSL - with only a few sections in SSL, or always on?
Yes, it's per URL, you could pick & choose if you wanted to. That said, in most cases it wouldn't be worth your time to do this selectively, just do the whole site if you're going to do a part of it.

comment Do noindex,follow pages pass pagerank / link juice?
Matt's statement is still correct. In a similar vein, pages that are disallowed from crawling in the robots.txt can also collect PageRank. These are essentially technical aspects of Google's algorithms, and not something you'd need to optimize for with most (probably all) real websites (I haven't seen any sites where either of these cases was causing a noticable problem).

comment Which meta names are case-sensitive?
FWIW I believe it's the same with other meta-tag verification setups, like those from Yandex and Bing.

comment Google sitemap priorities, am I doing the right thing?
FWIW Google pretty much doesn't use the priority value at all for web-search. changefreq only makes sense if you're not specifying a date (which you're doing here). Hope that saves you some unnecessary work :)

comment How to disallow robots from the first 185 pages?
Google recommends not using the robots.txt file as a way of handling duplicate content, so using the robots meta tag (or x-robots-tag HTTP header) is preferred.

comment Can Google index a non-80/non-443 URL?
You can definitely do that, but I'd tend towards using subdomains / hostnames: many users don't understand port numbers and might be confused with them (eg how do they recommend the website to others?).

comment Why has Google removed authorship images from its SERPs?
Just to add, authorship (as a concept & the semantics) itself isn't gone, it's really just the profile photos & the circle count. Google is still processing & using authorship markup, we're still showing the name of the author as well.

comment How do you tell search engines not to index this page just yet, but maybe in the future?
FWIW "follow" is the default behavior, you can drop it if you want (it doesn't cause any problems, and maybe it's meant more for humans reading it, so you can leave it too).

comment Should a website be directly accessible by its IP address?
This answer is definitely not true. Many websites are accessible on their IP address, it does not cause search engines headaches, it won't kill your "SEO." Duplicate content is a technical problem that has been around since the beginning of the web, search engines have various ways of dealing with it. It's not the end of the world. That said, if you have a preference regarding indexing, adding a rel=canonical is a great way to guide search engines towards that.

comment Search results for my website show content that isn't mine including pharmacy (Viagra and Cialis)
FWIW sometimes these hacks are only visible to search engines (IP addresses or user-agents), check with a tool like Fetch as Google if you're unsure: googlewebmastercentral.blogspot.ch/2009/11/…

comment Canonical tags for separate mobile URLs
If the primary content isn't equivalent, don't use the rel=canonical.

comment 404 - Page not found error while using Google's Instant Preview in Webmaster Tools
404 in the browser when accessing the tool, or the tool showed a 404 from your website?

comment Can we 301 redirect to a new page, but still publish the old content somewhere else?
Another idea is to have a more-generic page be the main landing page (eg /blue-widgets) which shows the current information, and have the archived pages (/2013/blue-widgets, etc) linked from there. That way, it's easy to focus on the current information (also for search), but still possible to find the rest.

comment Massive 404 attack with non existent URLs. How to prevent this?
A "404 attack" will definitely NOT affect your site's pagerank, nor its ranking. (If your competitors are spending time linking to pages that 404, that's less time they're spending on doing something useful, so be happy :).) Sites are supposed to have 404s, it's a sign that you have set up the server properly, so if anything, it would be a good signal for us.

comment Need to add 30K new pages to a 10K page website - troubles ahead? (SEO)
30k pages isn't that much, I'd just put them up at the same time (with the caveat that they should be great pages, otherwise I wouldn't put them up at all).
