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)

WordPress Sub-directory for SEO
Hi There, I'm working on a WordPress site that includes a premium content blog with approx 900 posts. As part of the project, those 900 posts and other membership functionality will be moved from the main site to another site built specifically for content/membership. Ideally, we want the existing posts to remain on the root domain to avoid a loss in link juice/domain authority. We initially began setting up a WordPress Multisite using the sub-directory option. This allows for the main site to be at www.website.com and the secondary site to be at www.website.com/secondary. Unfortunately, the themes and plugins we need for the platform do not play nicely with WordPress Multisite, so we started seeking a new solution, and, discovered that a second instance of WordPress can be installed in a subdirectory on the server. This would give us the same subdirectory structure while bypassing WordPress Multisite and instead, having two separate single-site installs. Do you foresee any issues with this WordPress subdirectory install? Does Google care/know these are two separate WordPress installs and do we risk losing any link juice/domain authority?

Lightboxes and SEO
Do lightboxes (AKA popup boxes when you click "learn more" type CTAs) have any negative effect on SEO? We are looking at revamping our sites to have more of a tiled approach, and a lightbox with summary content popping out with additional CTAs, directing to pages with more information or free trial pages. Is there any downside to this approach from an organic perspective? is there anything specific to keep in mind when creating these if not?

Are these URL hashtags an SEO issue?
Hi guys - I'm looking at a website which uses hashtags to reveal the relevant content So there's page intro text which stays the same... then you can click a button and the text below that changes So this is www.blablabla.com/packages is the main page - and www.blablabla.com/packages#firstpackage reveals first package text on this page - www.blablabla.com/packages#secondpackage reveals second package text on this same page - and so on. What's the best way to deal with this? My understanding is the URLs after # will not be indexed very easily/atall by Google - what is best practice in this situation?

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!

Are backlinks the most important factor in SEO?
I have had an agency state that "Backlinks are the most important factor in SEO". That is how they are justifying their strategy of approaching bloggers. I believe there are a lot more factors than that including Target Market definition, Keyword identification an build content based on these factors. What's everyone's thoughts?

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?
