How does Google handle pages with content that changes on each page load?
Google's Matt Cutts answers that question in a video:
"The short answer is: when we crawl a page, we basically know that snapshot that we fetch on that particular instant in time. If you have got something that rotates through, we might not necessarily see it. [...]
If you have five links and really care about one of these links, take that one out of the rotation and make sure that it is always on the homepage."
Google launches social search in 19 new languages
"Just like on google.com, social search results in other languages and on other domains are mixed throughout the Google results page based on their relevance. For example, if you're looking for information about low-light photography and your friend Marcin has written a blog post about it, that post may show up higher in your results with a clear annotation and picture of Marcin. [...]
So how does this all work? Social search results are only visible to you and only appear when you choose to log in to your Google Account."
Matt Cutts: a rel=canonical corner case
"We take rel=canonical urls as a strong hint, but in some cases we won't use them:
- For example, if we think you're shooting yourself in the foot by accident (pointing a rel=canonical toward a non-existent/404 page), we'd reserve the right not to use the destination url you specify with rel=canonical.
- Another example where we might not go with your rel=canonical preference: if we think your website has been hacked and the hacker added a malicious rel=canonical.
On the 'bright' side, if a hacker can control your website enough to insert a rel=canonical tag, they usually do far more malicious things like insert malware, hidden or malicious links/text, etc. [...]
Should Google trust rel=canonical if we see it in the body of the HTML? The answer is no, because some websites let people edit content or HTML on pages of the site."
Editor's note: Check your web pages now with the search engine spider simulator in the free IBP demo version to find out if your website shows the canonical tag to Google.
Google: easier URL removals for site owners
"When a page's URL is requested for removal, the request is temporary and persists for at least 90 days. We may continue to crawl the page during the 90-day period but we will not display it in the search results.
You can still revoke the removal request at any time during those 90 days. After the 90-day period, the page can reappear in our search results, assuming you haven't made any other changes that could impact the page's availability."
Matt Cutts: should internal links use rel="nofollow"?
"The answer is no. If you are linking from one page of your site to another page of your site, don't use nofollow. [...] I don't know how to make it more concrete than that."
The nofollow attribute should only be used if you link to a web page that you don't trust or endorse.
