Changing DNS -- SEO implications?
-
Hey Moz,
We're migrating an old site on an old server over to a new server/DNS. The plan is to keep the same URL structure and reuse our existing URL's. As long as we make minimal changes to each page's content, we should be able to update our DNS entry and get all the pages recreated and assigned to their correct URLs without any reduction in SEO rankings. Is this correct?
This site gets a lot of organic traffic and ranks highly on some challenging keywords, so it's key that we retain our rankings as much as possible.
I've read that it's wise to lower the DNS time-to-live to one hour, about a day before the move, to help Google crawl the DNS a little quicker.
Are there any other recommendations you guys can offer or past experiences?

Can you 301 from the DNS in HTTP or would you do an .htaccess

While the Bruce Clay link seems solid, I believe it is also quite dated. Steps 1 and 2 usually happen within minutes, not days. I have moved multiple sites between hosts without performing those steps and have not experienced any issue. I have also used tools to validate the results which use checkpoints from around the world and the transition happens very smoothly, very quickly.
If you have a static site which does not depend on User Generated Content (i.e. forums, etc.) the process is as easy as copying the old site to the new location, verifying the move, then updating the DNS records and 301'ing the old site to the new location. If anyone has a different experience from this year, I would love to hear additional feedback.

If all things end up be exactly the same your biggest risk is resetting your domains trust with Google. In theory a new website's owner may not run the website with the same credibility as the former owner... It is a risk to wear if you can justify the speed improvements cost differences etc...
The above being said it is something that happens on the net quite often. If your new structure will effectively be an improvement to users and you map everything correctly you should be o.k.
Here are some steps I have used before taken from the Bruce Clay Website:

How to move a site to a new host
If you are moving your site to a new IP address or ISP this procedure will help minimize the downtime and confusion during DNS propagation.
|

- Set up the DNS on your new host to point to your existing (old host) site first. This is an important first step.
- Now change the TLD (top level domain) information at your domain registrar to point to this new site DNS. Your old site should still show by either by IP or domain name. This step results in "propagation" which commonly takes 72 hours to update servers world-wide, so do not proceed with step 3 for about four days.
- Copy your existing site to your new site and validate that all files have transferred and the links work.
- After allowing 4 days for the DNS to be fully propagated, point your new DNS to your new site. Make sure that your old site mailboxes have been emptied before you change any DNS info at this time. Once this DNS change occurs you cannot get to your old mail.
- If everything has been validated you should now also point the old DNS to your new site. This is a safety issue in case there is a lingering propagation error.
- Search Engine rankings or bookmarked pages should transfer to your new site with a 301 redirect.
After everything has been checked you should be able to delete your old site after a sufficient amount of time has passed (not more than 3 months). Note that Google does cache the old DNS address information and until they verify that the site has moved and store the new DNS information they may not visit your new site. The 301 will assist in this area.
If you are moving from an IIS server to Linux (Apache) you should validate your formmail scripts, and any items that may not be cross platform compatible. If you are moving from Linux to IIS then your .htaccess file will not be compatible as well as the ability to CHMOD permissions. Validate all functions with your ISP Administrator (some of the following steps may need to be redone on your new server).

Do long UTM codes hurt SEO?
Since most UTM codes/URLs are longer than 70ish characters, is this hurting my SEO? If it is, how can I solve the problem while still using a UTM code? Thanks!

Craft CMS SEO Resources
I'm just starting out in freelance SEO & I've taken on a client who is using Craft CMS (version 2.0ish) for their site. I am not even close to being competent enough to manually code via Twig, but I had the main developer install the SEOmatic plugin for me. My question from here is - are there any resources or tips I should be aware of starting out? I just started by updating meta title/descriptions via "New Template Meta(s)" but I'm a bit concerned i'm doing the "template path" thing right - I haven't seen any visible changes in browser, and the SERP preview I'm getting is giving me a broken link. But i'm doing a fresh Moz crawl right now to see if the changes took place or not. so 1. Am I on the right track? 2. How long does it typically take for changes to start to show? 3. Is there anything I should be aware of? any follow up questions just let me know, I'll be following this thread!

Any SEO benefits of adding a Glossary to our website?
Hi all, I manage a website for a software company. Many terms can be quite tricky so it would be nice to add a Glossary page. Other than that, I have 2 questions: 1. What would be the SEO benefits? 2. How would you suggest to implement this glossary so we can get as much SEO benefit as possible (for example how would we link, where would we place the glossary in the terms of the sitemap, etc.). Any advice appreciated! Katarina

Coming soon SEO
Hi, I was wondering what is the best practice to redirect all the links juice by redirecting all the pages of your website to a coming soon page. The coming soon page will point to the domain.com, not to a subfolder. Should I move the entire website to a subfolder and redirect this folder to the coming soon page? Thanks

PageSpeed Insights DNS Issue
Hi Anyone else having problems with Google's Pagespeed tool? I am trying to benchmark a couple of my sites but, according to Google, my sites are not loading. They will work when I run them through the test at one point but if I try again, say 15 mins later, they will present the following error message An error has occured DNS error while resolving DOMAIN. Check the spelling of the host, and ensure that the page is accessible from the public Internet. You may refresh to try again. If the problem persists, please visit the PageSpeed Insights mailing list for support. This isn't too much an issue for testing page speed but am concerned that if Google is getting this error on the speed test it will also get the error when trying to crawl and index the pages. I can confirm the sites are up and running. I the sites are pointed at the server via A-records and haven't been changed for many weeks so cannot be a dns updating issue. Am at a loss to explain. Any advice would be most welcome. Thanks.

Changing menus regularly - will this impact SEO
We are working on an internal project, where the website owner is thinking of making regular changes to one or two items on the top level menu. Assuming they redirect the original pages or navigate to them in other ways, is there any other impact on SEO to changing the menu structure? I assume they'd submit new sitemaps after each change. Many thanks Fiona

International Seo - Canada
Our organization is currently only operating in the USA but will soon be entering the Canadian market. We did a lot of research and decided that for our needs it would be best to use a subfolder for Canada. Initially we will be targeting the english speaking community but eventually we will want to expand to the french speaking Canadians as well. The question is - is there a preferred version in setting up the subfolders: www.website.org/ca/ -- default will be english www.website.org/ca/fr/ - french www.website.org/en-ca/ - english www.website.org/fr-ca/ - french www.website.org/ca/en/ -english www.website.org/ca/fr/ - french Thanks

How much will changing IP addresses impact SEO?
So my company is upgrading its Internet bandwidth. However, apparently the vendor has said that part of the upgrade will involve changing our IP address. I've found two links that indicate some care needs to be taken to make sure our SEO isn't harmed: http://followmattcutts.com/2011/07/21/protect-your-seo-when-changing-ip-address-and-server/ http://www.v7n.com/forums/google-forum/275513-changing-ip-affect-seo.html Assuming we don't use an IP address that has been blacklisted by Google for spamming or other black hat tactics, how problematic is it? (Note: The site hasn't really been aggressively optimized yet - I started with the company less than two weeks ago, and just barely got FTP and CMS access yesterday - so honestly I'm not too worried about really messing up the site's optimization, since there isn't a lot to really break.)
