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)

Javascript and SEO
I've done a bit of reading and I'm having difficulty grasping it. Can someone explain it to me in simple language? What I've gotten so far: Javascript can block search engine bots from fully rendering your website. If bots are unable to render your website, it may not be able to see important content and discount these content from their index. To know if bots could render your site, check the following: Google Search Console Fetch and Render Turn off Javascript on your browser and see if there are any site elements shown or did some disappear Use an online tool Technical SEO Fetch and Render Screaming Frog's Rendered Page GTMetrix results: if it has a Defer parsing of Javascript as a recommendation, that means there are elements being blocked from rendering (???) Using our own site as an example, I ran our site through all the tests listed above. Results: Google Search Console: Rendered only the header image and text. Anything below wasn't rendered. The resources googlebot couldn't reach include Google Ad Services, Facebook, Twitter, Our Call Tracker and Sumo. All "Low" or blank severity. Turn off Javascript: Shows only the logo and navigation menu. Anything below didn't render/appear. Technical SEO Fetch and Render: Our page rendered fully on Googlebot and Googlebot Mobile. Screaming Frog: The Rendered Page tab is blank. It says 'No Data'. GTMetrix Results: Defer parsing of JavaScript was recommended. From all these results and across all the tools I used, how do I know what needs fixing? Some tests didn't render our site fully while some did. With varying results, I'm not sure where to from here.

Domain Migration Hell!
5 weeks ago we migrated our site to a new domain. We also installed an SSL certificate on the new domain. The new domain was purchased 5 years ago but we only used it as a redirect address. It was more consistent with our brand so we decided to migrate to it. Great care was taken setting up page to page redirects. A formal domain change request was made to Google. In fact the move was implemented with only a handful of broken links on a 500 page site. Those links were quickly fixed. Our traffic declined from about 350 visitors a week to as low as 40 visitors the first full week after the move. Now the number of organic Google visits is up to 80, a drop of 75% !!! All except 20 (out of 500) pages are reindexed on Google Search Console. MOZ domain authority for the new domain has climbed from 5 to about 12. The old domain had a DA of 23. In Google Search Console hundreds of "URL Not Allowed" errors are the site map for our previous domain that redirects to our new domain. Attached please see image of this. The site map for the new domain appears normal, but about 160 pages are indexed that are not in the sitemap. I wonder if these two issues have somehow contributed to the drop in ranking. I have included images showing GCT for the 2 domains. I posted on MOZ a month ago and was told it just might take time. No improvement and now I am wonder if there is not some issue with the sitemaps causing havoc. Are traffic is down more than 80%. This does not seem normal. Any advice? Any suggestions as to how to expedite recovery? Thanks,

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?

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 -
Recovering from a site migration
Hi. I've been working on http://www.alwayshobbies.com/ for a number of months. All was fine, but then we had a site migration which involved a huge number of redirects. There's been a couple of similar moves in the past. As a result, rankings have plummeted. To resolve this, we're considering letting all the old pages 404 by turning of the redirects, and removing all links to them where we can. Some key pages could have canonicals added, but basically we're looking to purge as much as possible. Does this sound like a reasonable tactic?

Effects of having both http and https on my website
You are able to view our website as either http and https on all pages. For example: You can type "http://mywebsite.com/index.html" and the site will remain as http: as you navigate the site. You can also type "https://mywebsite.com/index.html" and the site will remain as https: as you navigate the site. My question is....if you can view the entire site using either http or https, is this being seen as duplicate content/pages? Does the same hold true with "www.mywebsite.com" and "mywebsite.com"? Thanks!

Help with Effective Meta Description
Can someone give me a sample of an effective meta description tag? All of the best practice stuff I read doesn't talk about how to raise CTR. It seems to me that this is a neglected area of SEO, and we want to do this right. Obviously, we will need to test. For example, my main home page keyword is "IT Support" Things I might want to put in the tag: Free Network Assessments 100% Risk Free Trials "Relentless IT Support" (Major Theme) 30 Years of Experience (since 1984) Eliminate your IT Support Headaches Forever (Too long) Call to action? BTW, Thanks to everyone for your help. This is a great community. Solid advice from experts. Here's an example of what I would create Relentless IT Support Since 1984. Trust and Accountability. 100% Risk Free Trials. Contact us today for Free IT Assessment.
