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

One robots.txt file for multiple sites?
I have 2 sites hosted with Blue Host and was told to put the robots.txt in the root folder and just use the one robots.txt for both sites. Is this right? It seems wrong. I want to block certain things on one site. Thanks for the help, Rena

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

Log in, sign up, user registration and robots
Hi all, We have an accommodation site that asks users only to register when they want to book a room, in the last step. Though this is the ideal situation when you have tons of users, nowadays we are having around 1500 - 2000 per day and making tests we found out that if we ask for a registration (simple, 1 click FB) we mail them all and through a good customer service we are increasing our sales. That is why, we would like to ask users to register right after the home page ie Home/accommodation or and all the rest. I am not sure how can I make to make that content still visible to robots.

Will the authentication process block google crawling it? Maybe something we can do? We are not completely sure how to proceed so any tip would be appreciated. Thank you all for answering.3 -
Robots.txt and Multiple Sitemaps
Hello, I have a hopefully simple question but I wanted to ask to get a "second opinion" on what to do in this situation. I am working on a clients robots.txt and we have multiple sitemaps. Using yoast I have my sitemap_index.xml and I also have a sitemap-image.xml I do put them in google and bing by hand but wanted to have it added into the robots.txt for insurance. So my question is, when having multiple sitemaps called out on a robots.txt file does it matter if one is before the other? From my reading it looks like you can have multiple sitemaps called out, but I wasn't sure the best practice when writing it up in the file. Example: User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /wp-admin/ Disallow: /wp-content/plugins/ Sitemap: http://sitename.com/sitemap_index.xml Sitemap: http://sitename.com/sitemap-image.xml Thanks a ton for the feedback, I really appreciate it! :) J

Adding multi-language sitemaps to robots.txt
I am working on a revamped multi-language site that has moved to Magento. Each language runs off the core coding so there are no sub-directories per language. The developer has created sitemaps which have been uploaded to their respective GWT accounts. They have placed the sitemaps in new directories such as: /sitemap/uk/sitemap.xml /sitemap/de/sitemap.xml I want to add the sitemaps to the robots.txt but can't figure out how to do it. Also should they have placed the sitemaps in a single location with the file identifying each language: /sitemap/uk-sitemap.xml /sitemap/de-sitemap.xml What is the cleanest way of handling these sitemaps and can/should I get them on robots.txt?

Adding 'NoIndex Meta' to Prestashop Module & Search pages.
Hi Looking for a fix for the PrestaShop platform Look for the definitive answer on how to best stop the indexing of PrestaShop modules such as "send to a friend", "Best Sellers" and site search pages. We want to be able to add a meta noindex ()to pages ending in: /search?tag=ball&p=15 or /modules/sendtoafriend/sendtoafriend-form.php We already have in the robot text: Disallow: /search.php
Technical SEO | | reallyitsme
Disallow: /modules/ (Google seems to ignore these) But as a further tool we would like to incude the noindex to all these pages too to stop duplicated pages. I assume this needs to be in either the head.tpl or the .php file of each PrestaShop module.? Or is there a general site wide code fix to put in the metadata to apply' Noindex Meta' to certain files. Current meta code here: Please reply with where to add code and what the code should be. Thanks in advance.0
