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.

Content Based on User's IP Address
Hello, A client wants us to create a page on two different sites (www.brandA.com/content and www.brandB.com/content) with similar content and serve up specific content to users based on their IP addresses. The idea is that once a user gets to the page, the content would slightly change (mainly contact information and headers) based on their location. The problem I am seeing with this is that both brandA and brandB would be different Urls so there is a chance if their both optimized for the similar terms then they would both rank and crowd up the search results (duplicate content). Have you seen something similar? What are your thoughts and/or potential solutions? Also, do you know of any sites that are currently doing something similar?

Add Small Relevant Posts to website?
Hello Everyone, I'm starting a new WordPress-based community site WP Temple. As a part of this site, i'm going to be adding a "Code Snippets" Section which will show visitors how to do very specific things on their site. These snippets, by nature, will be small articles but contain highly-relevant for search. Should this content be indexed and followed, as well as added to my XML sitemap? I appreciate the feedback!

Including videos on an eCommerce website.
Hi,
Technical SEO | | ChrisHolgate
We're about to start integrating video content on our eCommerece site in order to bolster the quantity and diversity of useful content that each page presents a potential customer. We’re talking product reviews, information relating to the differences between different products and company information. From an SEO perspective it has been suggested that Google will like this however I have a question regarding the actual method of integration. Usually I would just insert some embed code linking to the correct video on our YouTube channel however I’m really conscious that a search engine will just see the embed code, notice the page loads slightly slower and not really gain anything useful from the video file. I’m assuming that this isn’t the case but I have several questions: - Would you host on YouTube and simply insert the embed code in to the page. Would any alternative site (or even self-hosted) be preferable? - Should I be padding out either side of the embed code with a description of the video and an annotation on OUR site? - Does Google actually look at the link and ascertain the relevance of the video file to the actual page? If it does this does it gain anything useful that could help on-page SEO? These are probably all pretty basic questions for which I do apologise but I want to make sure that before spending a sizable amount of time on this that we start off with a correct integration! Many thanks0 -
IP addresses indexed?
I've met with a potential client who has a site with 1,000's of very specific part #'s which don't show in the SERP's on Google. They definitely have the issue of dynamic URL's - but the URL for the part # searches is an IP address rather than their domain name - example: 188.888.888.888/partssearch.php?pnum='1233445' I've not seen the IP address used like this for an external website - is this acceptable for SEO purposes? Thanks, Mark

Google website-links changing back and fourth
Thought I might ask you guys if you have ever seen anything similar, 'cause I sure haven't. 🙂 I have a client who stumbled across a problem with his website links. Google change them back and fourth. one day one of the links will be called "iPhone 4 accessories" and some weeks pass and then it changes to " 4 accessories". Weeks pass again and then the iphone is back. First I thought to myself that Google might have expanded the AdWords filter to include website-links.. But then I remembered that they were ordered by the EU courts to size that practice.. so that can't be it. Plus allot of his competition doesn't seem to have the same problem. I have checked everything, the links, title tags, page titles exc.. and I acn't realt find any reason why this should be happening to him and I must admit I have never seen anything similar. Any hints and pointers would be most welcome 🙂
