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 International Targeting Not Working as Expected
If the pages are equivalent, make sure you set up the hreflang markup.

comment How hard is it to get back in the search results after being offline for a long time?
You can use the Fetch & Submit feature in Google Webmaster Tools to speed that up too. Usually you'd see individual URLs back in the index after a few days, so you probably see them already in the meantime :). It might take a while for things to rank again like they did in the past though (and Google's algorithms change regularly anyway, so it would never be identical).

comment Several headings inside <nav>
Most search engines aren't going to use a HTML5 parser and will just see multiple H1's. That said, I've never seen a site where this would cause any noticable change, I wouldn't be pedantic about "only one H1/page" for SEO purposes if you have good reasons to use that markup.

comment Google's cache is not using my custom font
The font-types don't really play a role for indexing, so that's not really something I'd lose any sleep over.

comment What’s up with this 302 redirect to the same URL?
stackoverflow.com/questions/20885695/… seems to have more details from Github on why they do this.

comment Is it safe to let anyone add my site in Google Webmaster Tools?
Another aspect is that as a verified owner, you can link the website to a YouTube channel (to make it official), to a Google+ page, and to apps uploaded in Google Play.

comment Is it safe to let anyone add my site in Google Webmaster Tools?
Regarding URL removals, in Webmaster Tools, as a verified owner, you can request complete removal of your website at any point, even if the website is still live. As a verified owner, Webmaster Tools assumes you know what you're doing.

comment Is it safe to let anyone add my site in Google Webmaster Tools?
I'd definitely avoid letting random people verify ownership of your site in Webmaster Tools, lots of things can be broken... Adding people with "read-only" access is less problematic, but even there they'd be able to see your search query data (which might be a competitive advantage), and see if URL removal requests were submitted.

comment How do search engine crawlers deal with imported HTML using link rel import tags?
FWIW if you block import.html via robots.txt, then that would also prevent its content from being picked up for indexing at all (even when pulled in via JavaScript like this). You can test this with "Fetch as Google" using the rendered option, in Webmaster Tools.

comment What's the smallest page size for Googlebot to not go “Soft 404”?
If Google is getting soft-404s wrong for your site, send me some sample URLs and I'll forward them to the team here. You shouldn't need to artificially tweak the response size.

comment Does Googlebot support SPDY?
With regards to potential future functionality, this kind of thing is something they would definitely consider, if they can see that it would have a significant impact. For example, if they see many servers that are overloaded with requests, where combining requests could allow better crawling, then maybe this would be an option. On the other hand, if it's only an option on servers that are already well-crawled, then it probably doesn't make that much sense.

comment Does Googlebot support SPDY?
I ended up talking with someone from the Googlebot team about this. At Google, we don't have these things documented (the list of things Googlebot doesn't do it pretty big), so I can't really point to anything as a reference.

comment Prevent Googlebot from seeing or indexing common keywords such as “read full story”
FWIW the content keywords report in Webmaster Tools is based on crawling, not indexing/ranking/relevance. Just because something's mentioned there doesn't mean that Google sees it as being relevant for the site. You don't need to optimize for that report.

comment How do I find when an URL was first indexed by Google?
Like others have mentioned, you can't get this information. If you have access to the server logs, you could see when it was first crawled, but even that doesn't mean that it was indexed then.

comment Can we use regex in robots.txt file to block URLs?
I'd caution from using too fancy directives in your robots.txt file; these are really, really hard to debug later on. Try to keep things as simple as possible. Also remember that robots.txt is case-sensitive, so you may need to add alternate versions of the directives depending on your site.

comment Where should I put the sitemap of mobile version of my site?
Keep in mind that mobile sitemaps (like you're using here) are meant for featurephone content (WAP, WML, etc), not for smartphone content. The solution for smartphone sites is in the answer below.
