SEO Impact of IPv4 and iPv6?
-
Thought I'd see what the asking side of Q&A feels like
We've been hearing for forever that the internet is running out of IP addresses, but I finally encountered the reality of it. I just realized that one of my sites is on a shared IP (hosted by Hosting.com, formerly HostMySite.com). My other sites with them included a unique IP, so I was surprised to discover this. They claim it's due to limitations on their IP allocations.
Hosting.com doesn't have the option to buy a unique IP, but some other hosts do. I noticed, though, that many of them are using IPv6 for the new accounts. Has anyone had practical experience with having an IPv6 address and is there any impact on SEO?

Shared IPs can cause issues with reverse lookups, which could make spiders confuse you with sites sharing that IP. Admittedly, it's rare, but there have been cases of penalties jumping within an IP, for example. I suspect that, as IP sharing grows, Google is getting better about this, but I generally like to avoid it.

Is a shared IP bad? My site shares an IP on GoDaddy.

Problems with Wordpress and Yoast SEO Plugin
Hi, I've been working with a Wordpress site and the Wordpress SEO plugin for a few months now and I've managed to get pretty decent results for some of the keywords I was targeting, however since last week I've lost all my rankings sharply and everything dropped out. This had happened once before and the problem was that the plugin was somehow stopped but not this time. I've had a look through all of the MOZ resources and I cannot find what the problem might be. Page optimization hasn't changed and the on page rankings are the same here. Everything seems to be the same except that all my top 10 ranking disappeared. I'm new to all of this and I'm still learning so I'd appreciate if anyone could help me on this. I'm up for trying any ideas you might have but I've tried almost everything I could. I've reinstalled, updated and done everything I could with the plugin, I've checked that Google is indexing the pages and it is. I've monitored for errors on the pages and critical issues, nothing major to report so I don't know anymore what to do. Thank you so much in advance for your help. M3rgAcQ paFNOlb

AJAX and SEO
Hello team, Need to bounce a question off the group. We have a site that uses the .NET AJAX tool kit to toggle tabs on a page. Each tab has content and the content is drawn on page load. In other words, the content is not from an AJAX call, it is there from the start. The content sits in DIV tags which the javascript toggles - that's all. My customer hired an "SEO Expert" who is telling them that this content is invisible to search engines. I strongly disagree and we're trying to come to a conclusion. I understand that content rendered async via an AJAX call would not be spidered, however just using the AJAX (Javascript) to switch tabs will not affect the spiders finding the content in the markup. Any thoughts?

Are Collapsible DIV's SEO-Friendly?
When I have a long article about a single topic with sub-topics I can make it user friendlier when I limit the text and hide text just showing the next headlines, by using expandable-collapsible div's. My doubt is if Google is really able to read onclick textlinks (with javaScript) or if it could be "seen" as hidden text? I think I read in the SEOmoz Users Guide, that all javaScript "manipulated" contend will not be crawled. So from SEOmoz's Point of View I should better make use of old school named anchors and a side-navigation to jump to the sub-topics? (I had a similar question in my post before, but I did not use the perfect terms to describe what I really wanted. Also my text is not too long (<1000 Words) that I should use pagination with rel="next" and rel="prev" attributes.) THANKS for every answer 🙂

SEO impact of adding a forum module to a site
I help maintain a site and the owners want to start a forum for their club members. This is a site that runs on Joomla, so it's likely we'll use some form of a Joomla module to add the forum functionality. My main question is whether there is anything to be concerned about for SEO purposes when adding the forum. I've never set one up, so I don't know the best practices for forums/discussion boards (although I'm scouring the web for general info). Should it be a subdomain or on the main domain -- or does this not matter? Are there any general setup processes that I should pay attention to for SEO best-practices? This question was mainly about the SEO impact, but if anyone can point me in the direction of forum best practice info as well, It would be appreciated. Cheers!

Will an identical site impact SERP results
I came across two identical sites for two different business owners in the same industry. I'm sure you've seen these. A web company offers individuals in the same profession a template site with the exact same content for each site. All that is different is the domain. i.e. mycompany.com/news/topicsname will have the exact same content, images, tags, etc. as mycompany2.com/news/topicsname. I would assume having the duplicate content, especially if two site owners are in the same town, will ultimately hurt the rankings of at least one site. Is this correct? Thank you for your help.

The best way to organize a gallery for SEO?
I need to redo the following gallery
Technical SEO | | UnderRugSwept
http://goo.gl/PFvjE
because besides the fact that it looks ugly, it's an SEO mess. Since all the pages are comprised of images, and the only text is the navigation, I'm getting duplicate content issues. I tried adding a little paragraph of text on some of the pages, but this thing needs a total revamp. My main question is this: is that menu being repeated on all the pages really a good thing? What good is it to, say, on the fire patches page, to have a menu that includes all these keywords for sports patches? Would it be better to just have a main gallery page that lists the main patch types: applique, motorcycle, Scouting, ect, and then once you get to that page, list all the different sub categories?0 -
