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).

If I change Tags and Categories in Wordpress blog post, will it negatively affect SEO and cause 404s?
Hi, I have belatedly come to the conclusion that I have been using tags and categories when blogging in wordpress incorrectly. The result is that Google seems to prefer to show my archives and tags in search results rather than the post itself. Not good UX. As the site is only a few months old, am I best to learn my lesson and tag and categorize correctly moving forward or Should I go back in to these posts and clean them up & categorize and tag correctly. If I do this, will it cause 404s and hurt my SEO? Thanks!

Schema for Banks and SEO
I'm researching Schema opportunities for a bank, but besides the shema markup available today (like bankorcreditunion) and developments with FIBO, I can find no answer as to the effect of tagging interest rates and such in terms of SERP/CTR performance or visibility. Does anyone have a case study to share or some insight on the matter?

URL path randomly changing
Hi eveyone, got a quick question about URL structures: I'm currently working in ecommerce with a site that has hundreds of products that can be accessed through different URL paths: 1)www.domain.com/productx 2)www.domain.com/category/productx 3)www.domain.com/category/subcategory/productx 4)www.domain.com/bestsellers/productx 5)... In order to get rid of dublicate content issues, the canoncial tag has been installed on all the pages required. The problem I'm witnessing now is the following: If a visitor comes to the site and navigates to the product through example 2) at time the URL shown in the URL browser box is example 4), sometimes example 1) or whatever. So it is constantly changing. Does anyone know, why this happens and if it has any impact on GA tracking or even on SEO peformance. Any reply is much appreciated Thanks you

Target: blank. Does it make an SEO difference?
I've notice many sites MOZ included no longer use the target: blank attribute. I think that's what it's called. Basically when a link on your site opens a new tab in the browser as opposed to replacing the browser window you are in. Given that MOZ think of everything, I would love to hear opinions on this.

Dynamically changing a title with javascript
Hi, I asked our IT team to be able to write custom page titles in our CMS and they came up with a solution that writes the title dynamically with javascript. When I look on the page, I see the title in the browser, but when I look in the source code, I see the original page title. I am thinking that Google won't see the new javascript title, so it will not be indexed and have no impact on SEO. Am I right ?
