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

Can OG titles be used as a substitute for Meta titles
We use og (open graph) titles in lieu of meta titles. Is there any downside to using just one. Should we be using both og and meta titles on our page. Appreciate any insight. Himanshu

What punctuation can you use in meta tags? Are there any Google does not like?
So I know you can use dashes and | in meta tags, but can anyone tell me what other punctuation you can use? Also, it'd be great to know what punctuation you can't use. Thanks!

What to do with temporary empty pages?
I have a website listing real estate in different areas that are for sale. In small villages, towns, and areas, sometimes there is nothing for sale and therefore the page is completely empty with no content except a and some footer text. I have thousand of landing pages for different areas. For example "Apartments in Tibro" or "Houses in Ljusdahl" and Moz Pro gives me some warnings for "Duplicate Content" on the empty ones (I think it does so because the pages are so empty that they are quite similar). I guess Google could also think bad of my site if I have hundreds or thousands of empty pages even if my total amount of pages are 100,000. So, what to do with these pages for these small cities, towns and villages where there is not always houses for sale? Should I remove them completely? Should I make a 404 when no houses for sale and a 200 OK when there is? Please note that I have totally 100,000+ pages and this is only about 5% of all my pages.

Blocking Affiliate Links via robots.txt
Hi, I work with a client who has a large affiliate network pointing to their domain which is a large part of their inbound marketing strategy. All of these links point to a subdomain of affiliates.example.com, which then redirects the links through a 301 redirect to the relevant target page for the link. These links have been showing up in Webmaster Tools as top linking domains and also in the latest downloaded links reports. To follow guidelines and ensure that these links aren't counted by Google for either positive or negative impact on the site, we have added a block on the robots.txt of the affiliates.example.com subdomain, blocking search engines from crawling the full subddomain. The robots.txt file is the following code: User-agent: * Disallow: / We have authenticated the subdomain with Google Webmaster Tools and made certain that Google can reach and read the robots.txt file. We know they are being blocked from reading the affiliates subdomain. However, we added this affiliates subdomain block a few weeks ago to the robots.txt, but links are still showing up in the latest downloads report as first being discovered after we added the block. It's been a few weeks already, and we want to make sure that the block was implemented properly and that these links aren't being used to negatively impact the site. Any suggestions or clarification would be helpful - if the subdomain is being blocked for the search engines, why are the search engines following the links and reporting them in the www.example.com subdomain GWMT account as latest links. And if the block is implemented properly, will the total number of links pointing to our site as reported in the links to your site section be reduced, or does this not have an impact on that figure?From a development standpoint, it's a much easier fix for us to adjust the robots.txt file than to change the affiliate linking connection from a 301 to a 302, which is why we decided to go with this option.Any help you can offer will be greatly appreciated.Thanks,Mark

No indexing url including query string with Robots txt

Should I block robots from URLs containing query strings?
I'm about to block off all URLs that have a query string using robots.txt. They're mostly URLs with coremetrics tags and other referrer info. I figured that search engines don't need to see these as they're always better off with the original URL. Might there be any downside to this that I need to consider? Appreciate your help / experiences on this one. Thanks Jenni
