Websites on same c class IP address
-
If two websites are on the same c class IP address, what does it mean ?
Does two websites belong to the same company ?
-
But if you have 20 sites linking to you, and they're all from the same Class C IP address, and those are pretty much your ONLY links, that looks a bit fishy to the search engines. It's a signal to the search engines that "hey, this person can only get links from sites that have a high probability of the same person being in control of all of the sites".
That's why you'll see people talk about linkbuilding and wanting to do so from different Class C IP addresses.
-
Not necessarily. f you see different C blocks, you are usually talking about two different webhosts. So there is a chance that different sites from one owner are hosted in one C-block.
Even an IP-address is not always used for one company. You can have your own IP-address which leads to your website. But providers can also share an IP-address for different domains/ websites for different companies.
To find if website belong tot the same owner you need to check te registars database or tools like allwhois.com.

Thanks Olaf.
So, does it mean that sites hosted on same C class IP belong to one owner ?
-
A "C" Block address is based on your IP address.
For example 190.245.111.001 is a standard IP address. The c-blocks in this case are: AAA.BBB.CCC.001-254
So these are within the same C-class:
190.245.111.001
190.245.111.230And these are different C-Class IP's:
190.245.111.001
190.245.222.001Google may assume that sites hosted in differnet C-blocks are more likely to be from different people.

How to Handle Website Merge?
We are a law firm and have another law firm merging into ours. Our branding will remain the same, but I am trying to figure out how to best handle their website transition. Should we link it to ours (although their PR & page authority are not significant) or should I map each page to ours with similar content with a redirect? MY main concerns are not damaging our website's SEO by doing something search engine's would frown on and also to try to take advantage of any organic traffic or referral traffic. Or maybe some combination - link homepage with added verbage that attorney is now with our firm and a link and redirect the sub-pages? I look forward to thoughts from anyone who might have experience with this type to issue. Thanks in advance! JulieHow t

How long does it take to reindex the website
Generally speaking, how long does it take for Google to recrawl/reindex an (ecommerce) website? After changing a number of product subcategories from 'noindex' back to 'index', I regenerated the sitemap and have fetched as Google in WMT. This was a couple of weeks ago and no action yet. Second question: Does Google treat these pages as if they're brand new? I 'noindexed' them back in April, and they were ranking ok then. (I had noindexed them on the back of advice from my SEO, due to concerns about these pages being seen as duplicate content). Help!

Optimizing a website which uses JavaScript and jQuery
Just a quick question (or 2) If I have divs which are hidden on my page, but are displayed when a user clicks on a p tag and the hidden div is displayed using jquery a user clicks on an a tag and the hidden div is displayed using jquery with the href being cancelled in both examples, will the hidden content be optimized, or will the fact it is initially hidden make it harder to optimize? Thanks for any answers!

Struggling to get my lyrics website fully indexed
Hey guys, been a longtime SEOmoz user, only just getting heavily into SEO now and this is my first query, apologies if it's simple to answer but I have been doing my research! My website is http://www.lyricstatus.com - basically it's a lyrics website. Rightly or wrongly, I'm using Google Custom Search Engine on my website for search, as well as jQuery auto-suggest - please ignore the latter for now. My problem is that when I launched the site I had a complex AJAX Browse page, so Google couldn't see static links to all my pages, thus it only indexed certain pages that did have static links. This led to my searches on my site using the Google CSE being useless as very few pages were indexed. I've since dropped the complex AJAX links and replaced it with easy static links. However, this was a few weeks ago now and still Google won't fully index my site. Try doing a search for "Justin Timberlake" (don't use the auto-suggest, just click the "Search" button) and it's clear that the site still hasn't been fully indexed! I'm really not too sure what else to do, other than wait and hope, which doesn't seem like a very proactive thing to do! My only other suspicion is that Google sees my site as more duplicate content, but surely it must be ok with indexing multiple lyrics sites since there are plenty of different ones ranking in Google. Any help or advice greatly appreciated guys!
