Empty Meta Robots Directive - Harmful?
-
Hi,
We had a coding update and a side-effect of that was that our directive was emptied, in other words it now reads as:
on all of the site.
I've since noticed that Google's cache date on all of the pages - at least, the ones I tested - have a Cached date of no later than 17 December '12 - that's the Monday after the directive was removed on mass.
So, A, does anyone have solid evidence of an empty directive causing problems? Past experience, Matt Cutts, Fishkin quote, etc.
And then B - It seems fairly well correlated but, does my entire site's homogenous Cached date point to this tag removal? Or is it fairly normal to have a particular cache date across a large site (we're a large ecommerce site).
Our site: http://www.zando.co.za/
I'm having the directive reinstated as soon as Dev permitting.
And then, for extra credit, is there a way with Google's API, or perhaps some other tool, to run an arbitrary list and retrieve Cached dates? I'd want to do this for diagnosis purposes and preferably in a way that OK with Google. I'd avoid CURLing for the cached URL and scraping out that dates with BASH, or any such kind of thing.
Cheers,
-
Can't answer the API question I'm afraid.
However on the other bits - if you don't specify robots directive, search engines are likely to behave in the default manner - i.e. index, follow unless you're blocking them another way (i.e. robots.txt)
A good test of this would be if you've launched a page since the 17th and it's not in Google's index and you know you've been crawled.
Check in GWT for your crawl data - and don't worry about the cache because your users will always be taken to the current version of your site. It's only a concern if you're no longer being crawled.
If it's an ecommerce site, then it should just be one site-wide tweak to put index,follow back in. Re-create and re-submit your sitemap.xml to GWT then Google will go after all your new content as well - i.e. it hurries up re-crawling.
Hoping something helped you there

Is having my homepage on a subfolder harmful?
Hi guys, I am the webmaster of the following two websites: www.gpblog.com/nl
Technical SEO | | NielsDE
www.gpblog.com/en The first URL is the Dutch version of GPBlog, the second URL is the UK version of GPblog. Whenever a person visits www.gpblog.com he gets redirected to either the Dutch version or the UK version based on his location. My question is: is it harmful to have 1. your homepage on a subfolder and 2. is it harmful to run two different languages on one domain using this technique? Thank you in advance!1 -

Google indexing despite robots.txt block
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!

Are robots.txt wildcards still valid? If so, what is the proper syntax for setting this up?
I've got several URL's that I need to disallow in my robots.txt file. For example, I've got several documents that I don't want indexed and filters that are getting flagged as duplicate content. Rather than typing in thousands of URL's I was hoping that wildcards were still valid.

Doing research for clients, I have came across seeing sites displaying hyperlinks underneath their own meta description. keywords that I have googled that result with hyperlinks displaying under meta descriptions: Google'd: iacquire (brand) bmw wheels (Beyern Wheels, position 1) aftermarket bmw wheels (MMR Wheels, position 2) These companys have hyperlinks underneath their descriptions. Anyone have any ideas why this happens or how it happens?

Robots.txt and canonical tag
In the SEOmoz post - http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts, it's being said - If you have a robots.txt disallow in place for a page, the canonical tag will never be seen. Does it so happen that if a page is disallowed by robots.txt, spiders DO NOT read the html code ?
