Server Migration, Does it effect SEO?
-
About to go through a server migration. My intitial thought is that a change in servers shouldn't really change my rankings. But I've heard rumors...
Can a server migration change rankings? Why?
-
No language change on the servers. I know I shouldn't be worried but hey, it's my baby. All grown up and going off to a college of her own now...
The upgrade should help with site speed so I am hoping that I might get a boost.
-
Good to know that the SEO isn't harmed if there are no errors... I can see how a site missing the htaccess could be damaging. Ouch.
-
As long as the site and URL structure remain unchanged, then a server migration shouldn't make any impact in the rankings.
That being said, there are a few relatively uncommon things that could potentially cause some issues -
1. If you are going to be moving from a PHP server to an IIS server and you need to change your URLs to .asp or something like that, then you make take a temporary hit while the search engines crawl and index the new versions.
2. If the new server is slower or is prone to frequent downtime, then yes, it could negatively affect your rankings.
3. If you are moving to a new shared server, make sure the rest of the sites on that server are all legitimate sites that haven't been blacklisted by the search engines for any reason. For example, if you move your site to a server that has 100 Russian sites or Nigerian spammer sites all on the same IP, then it's possible your site could be negatively impacted.
Again, these are all relatively uncommon scenarios as long as you are simply moving your site over to another server while keeping everything else the same, so you shouldn't notice any difference in your rankings.
-
Unless the layout was changed or things went wrong, no. I've migrated maybe 50 websites over the past year with no ill effects. Any that did, occurred because something went wrong (htaccess issues, extended downtime) or because there was a design change. In the case of the latter, rankings return any time between a few days to a few weeks. (Assuming the markup/content is still good)

Why is pagination SEO such a mystery in 2021?
Hi folks. I would like to discuss pagination. I use WordPress (Genesis, specifically). I ran my site through a site scan and it flagged an error which told me that my blog was producing duplicate meta descriptions because the blog is paginated - the same meta description from the blog page is being used on Page 2, Page 3 etc. I looked into this and the Internet is awash with many other people scratching around for a solution. My understanding is that using a canonical link on the first page is not a good idea, because it says to Google that only Page 1 of the blog is important. I also read an article that states Google no longer reads the Rel=Prev/Next code that could be used to tell Google to ignore the issue. So, what's the solution? Do I even need one? As a side-thought, it seems to me that pagination is, well, pretty useless. I mean, if my blog has 20 pages and I've worked hard to create content, who is going to click through to anywhere near page 20? Nobody. There has to be a smarter way for people on-site to access content. I would love your thoughts on all of this. Cheers.

Is tabbed content bad for SEO?
I work for a Theater show listings and ticketing website. In our show listings pages (e.g. http://www.theatermania.com/broadway/this-is-our-youth_302998/) we split our content into separate tabs (overview, pricing and show dates, cast, and video). Are we shooting ourselves in the foot by separating the content? Are we better served with keeping it all in a single page? Thanks so much!

Should I redirect images when I migrate my site
We are about to migrate a large website with a fair few images (20,000). At the moment we include images in the sitemap.xml so they are indexed by Google and drive traffic (not sure how I can find out how much though). Current image slugs are like:
Intermediate & Advanced SEO | | ArchMedia
http://website.com/assets/images/a2/65680/thumbnails/638x425-crop.jpg?1402460458 Like on the old site, images on the new website will also have unreadable cache slugs, like:
http://website.com/site_media/media/cache/ce/7a/ce7aeffb1e5bdfc8d4288885c52de8e3.jpg All content pages on the new site will have the same slugs as on the old site. Should I go through the trouble of redirecting all these images?0 -

Is DOCTYPE important for SEO?
Hello fellow Mozzers. I am just having a brief look at a potential clients website before speaking to them tomorrow and whilst looking at the source I noticed that they don't appear to have a clear definition for their Doctype. All the have at the top of each page is I have to admit that Doctypes aren't my strong point but I know that they are normally slightly more descriptive than this. Can this have any effect on rankings? or is this just an issue for W3C validation? Thanks 🙂

URL Shorteners. Are they SEO Friendly?
Do URL shortener services like bit.ly act as 301 redirects? I was thinking about utilizing one for longer query based URLs and didn't want to risk losing link juice. Thanks for the insight! Regards - Kyle

Subdomains and SEO - Should we redirect to subfolder?
A new client has mainsite.com and a large numer of city specific sub domains i.e. albany.mainsite.com. I think that these subdomains would actually work better as subfolders i.e mainsite.com/albany rather than albany.mainsite.com. The majority of links on the subdomains link to the main site anyway i.e. mainsite.com/contactus rather than albany.mainsite.com/contactus. Having mostly main domain links on a subdomain doesnt seem like clever link architecture to me and maybe even spammy. Im not overly familiar with redirecting subdomains to subfolders. If we go the route of 301'ing subdomains to subfolders any advice/warnings?
