Impact of 401s on Site Rankings
-
Will having 401s on a site negatively impact rankings? (e.g. 401s thrown from a social media sharing icon)
-
Hi! We're going through some of the older unanswered questions and seeing if people still have questions or if they've gone ahead and implemented something and have any lessons to share with us. Can you give an update, or mark your question as answered?
Thanks!
-
So how would you block spiders from crawling social media sharing icons? Or is there another workaround?
-
Yes, I believe any http error response is a bad thing and could affect your ranking. Even 404's or 301's (when links on-site or in sitemap cause them) are cause for concern. You want to make your site as squeaky clean as possible.
I regularly use a site crawler to check my site, including sitemap/rss feeds, and fix any non-200 responses.

First here is an error list: http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=40132
Response code 403 is for requests, where authentication makes no difference, disabled directory browsing.
401 Unauthorized would be the response to send.I'd suggest using robot.txt to stop going to these pages? Or even better, if you can allow Google's spiders access (I'm not 100% sure how this is done)

Page Rank Flow
I wonder if someone can help me understand clearly page rank flow. If we have a website with a Home page, Services, About and Contact as a very basic website and the page rank will flow to each of those pages from the Home page (i'm not including internal linking between pages or anchor text from the home page content - this is a question purely about home page flow via the main navigation). If the Services page had 3 drop down pages. Would the home page rank also flow to each of these or is it going to the Services page which then distributes it to the three drop down. So instead of Home page rank flowing to 3 pages 33% each - it is flowing to 6 pages 16.6% each. Or is it flowing to 3 pages - 33.3% then the Services pages get a third of 33.3% ->10.1% I know this is simplifying it all a great deal- but it is the basic concept I am trying to grasp on this simple example. Thanks

Hey guys, for some reason my homepage has gone down in rankings though other pages on my site have not.
This is not something I have ever seen before. The site is still indexed if I search for it directly, but not in top 100 rankings for keywords even though sub-pages are ranking for the given keyword. Changes I have made recently include site transfer to wordpress, force redirect http to https removal of www by redirect and adding new property instance in Google Search Console. I have checked htaccess file and sitemap and all seem fine. ideas? Site: https://dublinSEO.co

How Long To Recover Rankings After Multi-Day Site Outage?
Hi, A site we look after for a client was down for almost 3 days at the start of this month (11th - 14th of May, to be exact). This was caused by my client's failure to verify their domain name in accordance with the new ICANN procedures. The details are unimportant, but it took a long while for them to get their domain name registration contact details validated, hence the outage. Very soon after this down time we noticed that the site has slipped back in the Google rankings for most of the target keywords, sometimes quite considerably. I guess this is Google penalizing this client for their failure to keep their site live. (And they really can't have too many complaints about this, in my opinion). The good news is that the rankings show signs of improving again slightly. However, they have not recovered all the way to where they were before the outage, two weeks ago. My question is this ... do you expect that the site will naturally re-gain the previous excellent rankings without us doing anything? If so, how long do you estimate this could take? On the other hand, if Google typically penalizes this kind of error by 'permanently', is there is anything we can do to help signal to Google that the site deserves to get back up to where is used to be? I am keen to get your thoughts, and especially to hear from anyone who has faced a similar problem in the past. Thanks

Staging site and "live" site have both been indexed by Google
While creating a site we forgot to password protect the staging site while it was being built. Now that the site has been moved to the new domain, it has come to my attention that both the staging site (site.staging.com) and the "live" site (site.com) are both being indexed. What is the best way to solve this problem? I was thinking about adding a 301 redirect from the staging site to the live site via HTACCESS. Any recommendations?

How to create site map for large site (ecommerce type) that has 1000's if not 100,000 of pages.
I know this is kind of a newbie question but I am having an amazing amount of trouble creating a sitemap for our site Bestride.com. We just did a complete redesign (look and feel, functionality, the works) and now I am trying to create a site map. Most of the generators I have used "break" after reaching some number of pages. I am at a loss as to how to create the sitemap. Any help would be greatly appreciated! Thanks

Mobile site ranking instead of/as well as desktop site in desktop SERPS
I have just noticed that the mobile version of my site is sometimes ranking in the desktop serps either instead of as well as the desktop site. It is not something that I have noticed in the past as it doesn't happen with the keywords that I track, which are highly competitive. It is happening for results that include our brand name, e.g '[brand name][search term]'. The mobile site is served with mobile optimised content from another URL. e.g wwww.domain.com/productpage redirects to m.domain.com/productpage for mobile. Sometimes I am only seen the mobile URL in the desktop SERPS, other times I am seeing both the desktop and mobile URL for the same product. My understanding is that the mobile URL should not be ranking at all in desktop SERPS, could we be being penalised for either bad redirects or duplicate content? Any ideas as to how I could further diagnose and solve the problem if you do believe that it could be harming rankings?

Changing images on site without losing ranking
A number of images on my site rank very well under google image search but need to be replaced with updated versions. If I keep the file name and pixel dimensions identical will switching the image effect my rankings? Thanks!
