How to handle web server downtime?
-
We have a client who is taking their web server down Saturday morning from 1am - 7am for planned maintenance. Initially, we thought to have all requests return a 503 (service unavailable) response but the web server itself will be down so we are not able to have it return any response codes. Updating the DNS on the registrar will have too much lag time while it propogates out so we aren't sure exactly how to handle this. I had thought possibly of using a second DNS, or a service like DynDNS but that seems like a large amount of effort to set up just for some planned downtime. I have to imagine that Google understands planned website/server downtime every once in a great while.
This client has pretty good rankings for some incredibly competitive terms so we want to do all that we can to make sure those rankings are preserved. What are some other potential solutions? We could totally just be overthinking this but we'd rather be safe than sorry...
Thanks in advance!

We had an excellent post about that from a YouMoz author in January. http://www.seomoz.org/blog/how-to-handle-downtime-during-site-maintenance should tell you everything you need to know!

Yes, I would not worry about it. Google understands these issues specially on large scale websites. I have worked in scenarios where there's a weekly rebuild or deployment which essentially means the site is down for 2-6 hrs. Nothing happens. In a rare occasion, if your page with the maintenance message gets cached, you can always request a re-crawl of upto 50 pages from your Google Webmaster Console. I have never had to do that.

Our site is on a secure server (https) will a link to http:// be of less value?
Our site is hosted on a secure network (I.E. Our web address is - https://www.workbooks.com). Will a backlink pointing to: http://www.workbooks.com provide less value than a link pointing to: https://www.workbooks.com ? Many thanks, Sam

When Mobile and Desktop sites have the same page URLs, how should I handle the 'View Desktop Site' link on a mobile site to ensure a smooth crawl?
We're about to roll out a mobile site. The mobile and desktop URLs are the same. User Agent determines whether you see the desktop or mobile version of the site. At the bottom of the page is a 'View Desktop Site' link that will present the desktop version of the site to mobile user agents when clicked. I'm concerned that when the mobile crawler crawls our site it will crawl both our entire mobile site, then click 'View Desktop Site' and crawl our entire desktop site as well. Since mobile and desktop URLs are the same, the mobile crawler will end up crawling both mobile and desktop versions of each URL. Any tips on what we can do to make sure the mobile crawler either doesn't access the desktop site, or that we can let it know what is the mobile version of the page? We could simply not show the 'View Desktop Site' to the mobile crawler, but I'm interested to hear if others have encountered this issue and have any other recommended ways for handling it. Thanks!

Mixing static.htm urls and dynamic urls on a Windows IIS Server?
Hi all, We've had a website originally built using static html with .htm extensions ranking well in Google hence we want to keep those pages/urls. We are on a dedicated sever (Windows IIS). However our developer has custom made a new DYNAMIC section for the site which shows new added products dynamically and allows them to be booked online via shopping cart. We are having problems displaying them both on the same domain even if we put the dynamic section withing its own subfolder and keep the static htms in the root. Is it possible to have both function on IIS (even if they may have to function a little separately)? Does anyone have previous experience of this kind of issue or a way of making both work? What setup do we need to do on the dedicated server.

Magento Help - Server Reset
Good Morning, After rebooting a server, a magento based website reset itself going back to December 2013. All changes to the site and orders dating up until yesterday (6/19/14) have disappeared. There are several folders on the root of the server that have files with yesterday's date but we don't know how to bring everything back and restore. Any Magento or server experts out there ever face this issue or have any ideas or potential solutions? Thanks

Does having all client websites on same server/same Google Analytics red flag Google?
If you have several clients, and they are all on the same server, and also under ONE Google Analytics account, will that negatively impact with Google? They all have different content and addresses, some have the same template, but with different images.

Redirect at Registrar or Server
Hi folks, I have run into a situation were a new client has 3 TLDs (e.g. mycompany.com, mycompany.org and mycompany.biz), all with the same content. They are on a Windows IIS environment, which I am not familiar with. Until now, all of my clients have been Linux/Apache environment, so I always dealt with these issues utilizing htaccess. Currently all resolve to the same IP, but the URL remains the same in the browser address field (e.g. if you type-in mycompany.org - it remains as such). We want the .org and .biz version to 301 Redirect to the .com TLD. I am wondering what the best practice might be in this situation? Could we simply redirect at the registrar level or would implementation at the server level be best? If so, I would really appreciate an example from someone with experience implementing redirects on IIS. Thank you!

Thousands of Web Pages Disappered from Google Index
The site is - http://shop.riversideexports.com We checked webmaster tools, nothing strange. Then we manually resubmitted using webmaster tools about a month ago. Now only seeing about 15 pages indexed. The rest of the sites on our network are heavily indexed and ranking really well. BUT the sites that are using a sub domain are not. Could this be a sub domain issue? If so, how? If not, what is causing this? Please advise. UPDATE: What we can also share is that the site was cleared twice in it's lifetime - all pages deleted and re-generated. The first two times we had full indexing - now this site hovers at 15 results in the index. We have many other sites in the network that have very similar attributes (such as redundant or empty meta) and none have behaved this way. The broader question is how to do we get the indexing back ?

How to handle link building to product pages that change regularly?
How do I handle building links to an eCommerce site where the product pages change regularly because product is only available for a certain time frame? Should I focus on building links to the category pages instead?
