A/B testing entire website VS Seo issues
-
I'm familar with A/B testing variations of a page but I'd like to A/B test a new designs version of a e-commerce site. I´m wondering about the best way to test with SEO concerns... this is what I´ve in mind right now, any suggestion?
- Use parameters to make version B different from A version.
- Redirect 50% of the users with 302 ( or javascript would be a better way?)
- Use noindex in the B pages.
- Use rel=canonical in the B pages pointing to A version.
- In the end use 301 redirect to all B pages to A urls.
PS: We can´t use subdomain and i don´t wanna use robots.txt file to protect the new design from competitors.
I´d love any suggestions and tips about it - thanks folks

My main experience with A/B is via Google Experiments and it looks like they highlight option 4:
To ensure that serving your variation pages does not have a negative impact on your site's SEO rankings, you can use the
rel="canonical"
link attribute on your variation pages.rel="canonical"
is a signal to search engines that the content of your variation pages is essentially the same as that of your original page, and that you would prefer that search engines index your original page rather than the variations you're using in your experiment.Source: https://support.google.com/analytics/answer/2613318
If you roll out rel=canonical correctly then this seems to be your safest bet in Google's eyes. My main experience is with split-testing single pages, but theoretically this should work out okay with the correct use of canonical. If you're really not sure you could roll out a mini-test with a couple of key pages first?

Home Page Being Indexed / Referral URLs /
I have a few questions related to home page URLs being indexed, canonicalization, and GA reporting... 1. I can view the home page by typing in domain.com , domain.com/ and domain.com/index.htm There are no redirects and it's canonicalized to point to domain.com/index.htm -- how important is it to have redirects? I don't want unnecessary redirects or canonical tags, but I noticed the trailing slash can sometimes be typed in manually on other pages, sometimes not. 2. When I do a site search (site:domain.com), sometimes the HP shows up as "domain.com/", never "domain.com/index.htm" or "domain.com", and sometimes the HP doesn't show up period. This seems to change several times a day, sometimes within 15 minutes. I have no idea what is causing it and I don't know if it has anything to do with #1. In a perfect world, I would ask for the /index.htm to be dropped and redirected to .com/, and the canonical to point to .com/ 3. I've noticed in GA I see / , /index.htm, and a weird Google referral URL (/index.htm?referrer=https://www.google.com/) all showing up as top pages. I think the / and /index.htm is because I haven't setup a default URL in GA, but I'm not sure what would cause the referrer. I tracked back when the referrer URL started to show up in the top pages, and it was right around the time they moved over to https://, so I'm not sure what the best option is to remove that. I know this is a lot - I appreciate any insight anyone can provide.

Http:// vs Https:// in Og:URL
Hi, Recently, we have migrated our website from http:// to https://. Now, every URL is in https:// and we have used 301 permanent redirection for redirecting OLD URL's to New Ones. We have planned to include http:// link in og:url instead of https:// due to some social share issues we are facing. My concern is, if Google finds the self http:// URL on every page of my blog, will Google gets confused with http and https:// as we are providing the old URL to Google for crawling. Please advice. Thanks

Negative SEO
I have got some idiot bombarding my site with spam links, most likely a negative SEO attempt. It started off very small and has ramped up to between five and 10 spam links per day. I think it may be having a slightly negative affect although difficult to tell. I can do a link cleanup, but I'm not sure that is a long term solution, I'm just going have to do it again in a few weeks time. Does anyone have any experience?

SEO Content Audits Questions (Removing pages from website, extracting data, organizing data).
Hi everyone! I have a few questions - we are running an SEO content audit on our entire website and I am wondering the best FREE way to extract a list of all indexed pages. Would I need to use a mix of Google Analytics, Webmaster Tools, AND our XML sitemap or could I just use Webmaster Tools to pull the full list? Just want to make sure I am not missing anything. As well, once the data is pulled and organized (helpful to know the best way to pull detailed info about the pages as well!) I am wondering if it would be a best practice to sort by high trafficked pages in order to rank them for prioritization (ie: pages with most visits will be edited and optimized first). Lastly, I am wondering what constitutes a 'removable' page. For example, when it is appropriate to fully remove a page from our website? I understand that it is best, if you need to remove a page, to redirect the person to another similar page OR the homepage. Is this the best practice? Thank you for the help! If you say it is best to organize by trafficked pages first in order to optimize them - I am wondering if it would be an easier process to use MOZ tools like Keyword Explorer, Page Optimization, and Page Authority to rank pages and find ways to optimize them for best top relevant keywords. Let me know if this option makes MORE sense than going through the entire data extraction process.

Should I change hosting / registration when buying an established website?
I am buying an established website that is currently ranking very well for several keywords. I have no intentions of changing anything on the site. My question is, will it matter if I change where the site is hosted, and the whois information (I want to change it from public to private)? i.e., I don't want to do anything to mess up the current rankings of the site - will these changes have any effect? Thanks for the help.
