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

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!

Meta Description VS Rich Snippets
Hello everyone, I have one question: there is a way to tell Google to take the meta description for the search results instead of the rich snippets? I already read some posts here in moz, but no answer was found. In the post was said that if you have keywords in the meta google may take this information instead, but it's not like this as i have keywords in the meta tags. The fact is that, in this way, the descriptions are not compelling at all, as they were intended to be. If it's not worth for ranking, so why google does not allow at least to have it's own website descriptions in their search results? I undestand that spam issues may be an answer, but in this way it penalizes also not spammy websites that may convert more if with a much more compelling description than the snippets. What do you think? and there is any way to fix this problem? Thanks!

Two META Robots tags on a page - which will win?
Hi, Does anybody know which meta-robots tag will "win" if there is more than one on a page? The situation:
Technical SEO | | jmueller
our CMS is not very flexible and so we have segments of META-Tags on the page that originate from templates.
Now any author can add any meta-tag from within his article-editor.
The logic delivering the pages does not care if there might be more than one meta-robots tag present (one from template, one from within the article). Now we could end up with something like this: Which one will be regarded by google & co?
First?
Last?
None? Thanks a lot,

Robots.txt to disallow /index.php/ path
Hi SEOmoz, I have a problem with my Joomla site (yeah - me too!). I get a large amount of /index.php/ urls despite using a program to handle these issues. The URLs cause indexation errors with google (404). Now, I fixed this issue once before, but the problem persist. So I thought, instead of wasting more time, couldnt I just disallow all paths containing /index.php/ ?. I don't use that extension, but would it cause me any problems from an SEO perspective? How do I disallow all index.php's? Is it a simple: Disallow: /index.php/

Can I Disallow Faceted Nav URLs - Robots.txt
I have been disallowing /*? So I know that works without affecting crawling. I am wondering if I can disallow the faceted nav urls. So disallow: /category.html/? /category2.html/? /category3.html/*? To prevent the price faceted url from being cached: /category.html?price=1%2C1000

Should I set up a disallow in the robots.txt for catalog search results?
When the crawl diagnostics came back for my site its showing around 3,000 pages of duplicate content. Almost all of them are of the catalog search results page. I also did a site search on Google and they have most of the results pages in their index too. I think I should just disallow the bots in the /catalogsearch/ sub folder, but I'm not sure if this will have any negative effect?
