A/B Split Testing - Rankings Drop? Need an expert opinion...
-
We are running an A/B split test (Started on 12/12), and a few days after we started the test, we fell from position 9/10 (about 3 weeks on page 1) to position 11/13, and we've been there ever since.
We are still running the test. We disallowed the test page in robots.txt, but that's all.
- no canonical
- no noindex
-no Google Experiments code.
Theoretically, Google could crawl the site, and find the page, but then the page is disallowed. The alternate page is not indexed.
Could this explain the rankings drop?
-
It's a big site, and the most important category page. It explains a lot.

How big is your site? Is the page being A/B tested a pretty strong page (PA, PR)?
Let's say you've got a relatively small site, with a few dozen pages, and the page in question is one of only a couple linked to from the main nav. So it's one of the stronger pages on the site. Blocking it in robots.txt means Google isn't going to continue to distribute link juice from that page to other pages on your site, so all of those other pages get slightly weaker.
In general, robots.txt isn't the place to block Google, as you throw away the outbound link juice from that page that's blocked. Instead, you'd want to do a meta robots noindex,follow on the page itself.
If you've got a big site, and this particular landing page isn't a major portion of the overall site in terms of PA, then you shouldn't have seen an effect like I've described.

Lost ALL my rankings
Dear experts, We have suddenly lost all our positions on our keywords, I’m talking for example from position 2 to 35 in one huge drop ☹ . Even when you search for our name and domain name namely “KV16”, the main page does NOT come up. (We do however still get the local business / map result on the right side!) I have looked in google search console, but nothing to see here – no penalty. However, I need to mention, that we just now, after the issue, setup the google search console – so maybe that is why there is no information about a penalty!? (If the problem is a penalty, btw we have not been doing any link building!) One year ago, we made a permanent redirect from our old site, www.kontoret-gammeltorv.dk, because we moved our coworking office, to a new location, and needed a new name – (because the old name is referring to a location, hence no longer made sense.) This worked flawlessly, and we got all the link juice, and the new site ranked just as good as the old one. Aprox four months ago, we made some changes to the site, where we amongst other things, changed the title description on the frontpage, focusing more on another keyword – and doing this we unknowingly change the permalink to the frontpage (in WordPress). I have read that this can do some real damage, however its so long ago, that it seems unlikely to be the cause!? Please help!? Thanks a million, in advance. Cheers, Christian pJp4Uyx

Ranking fluctuation
Has anybody got any ideas? I have a website that ranks quite well for an industry keyword, the site has a reasonable amount of authority. But the term is fluctuating between position 3 and position 9! It is on a beefy stable server. It is reasonably well optimised from both SEO and speed point of view. It is tracked using Moz RankTracker. I do realise that rankings fluctuate, but this is ridiculous!

Website redesign, some urls are no longer available. How do I mitigate ranking drops?
I am currently refreshing my WordPress business website. I used a theme that had a built in portfolio option. I wanted to strip down the bloat and move to something more simple to better articulate my message. Upon switching themes I will loose my urls for my portfolio projects. I should have never used this built in function but it did exactly what I needed and wanted here is an example. http://silvernailwebdesign.com/portfolio-view/central-jersey-claims-association-wordpress-consulting/ Now on my staging site these portfolio pieces have vanished and the urls are indexed with google. I could create posts and recreate the portfolio pieces however the problem with the url is the /portfolio-view/ portion. I cannot recreate the part of the url. Any advice would be greatly appreciated. I receive some traffic through the portfolio pages but not much, however, I do not want to loose any traffic. I am looking for a strategy that will solve this url issue with WordPress. I have about 10 separate portfolio pages with this url issue.

Site Rollback for Careless Website Design That Caused Rank Drop
New PPC Client (out of necessity) had their site redesigned for mobile without much care given to it by a "SEO Expert". None of the meta data was copied over to the new images and pages, much of the old content was simply deleted, intra site links completely changed. Huge hits in organic rank, resulting in traffic declines occurred as their lead volume hit zero the following month (April 21 until Present). Any concerns I should have in doing a simple rollback beyond redirects and GWT (Search Console) ops? Current plan is 1. Setup redirects back to old site 2. Launch PPC campaign to recover call volume and leads. 3. Optimize old site for mobile simultaneously with simple responsive framework for menu, text. 4. Start disavowing poor-quality links that were added (got 10 with spam rating >4). 5. Eventually move them back to Wordpress and the theme they paid for with site content, meta data, etc all in tact.

Links / Metadata around Recent Posts etc in Wordpress / Blog - Good SEO Practice?
Hello In a Wordpress blog ( or part of an ecommerce site that runs under wordpress ) it is good to show recent posts in the sidebar on most pages. Obviously the posts aren't going to be relevant to every post , so my questions are: Is having these on the page hurting SEO for the page? Is there good metadata structure to put in there? ( like rel="nofollow" or similar ) Thoughts?

Ranking strangeness
Just wondering if anyone had come across this kind of scenario which I had/have with a client. Rebuilt/revamped site that has got problems with thin content we are looking to resolve. Rankings for the main keywords were ok on page 2 or 3 and being worked on. Two weeks ago ALL main keywords disappeared from ranking (category pages). The homepage took over and ranked ALL those keywords at #1! Bang -straight to top spot. However happy I was I find this disconcerting as there is a reasonable level of competition. Today homepage rankings in the main go and directories come back into the rankings at some good positions on page one. We still need to fix thin and duplicated content! I can justify the problems and swing with the category pages but the massive cross the board top position for the homepage has been pretty bizarre. Has anyone else had the experience where the homepage suddenly 'out-performs' in a big way?

Would love a second opinion
Hi Mozzers, i have been tirelessly working on our site www.palicomp.co.uk for the past few months auditing and fixing what we can, we have recently recovered from a mind bending google panda penalty, but i would really love a second quick glance from another mozzer to see if theres anything glaringly obvious that we have missed onpage or looks wrong if anyone has 2 minutes of time to give 🙂
