Just wondering what are the pros and cons of linking your own websites? How does google know you own them? I have noticed people talking about C-block or some IP thingy..what is that?
if you have a little number of sites you can crosslink them but I would not recommend to crosslink a big number of sites. (lets say 100 sites). Because google will see this as manipulation, and artificial link network and you could get penalized. You can use a hub and spoke method. From all sites you link to one your's "authority site" and then you link from that site to other sites.
IP addresses are divided into classes taht some peopel refered to as blocks. There are 5 of them called Class A IP Addresses, Class B IP Addresses, Class C IP Addresses, Class D IP Addresses and Class E IP Addresses. Class D is for multicast transmissions and Class E is reserved. That leaves us with A, B and C. Class A is 0.0.0.0 through 126.255.255.255; Class B is 128.0.0.0 through 168.255.255.255 and 170.0.0.0 through 191.255.255.255; and Class C is 192.0.0.0 through 223.225.225.225. So what people mean by C-block addresses are IP addresses in the range 192.0.0.0 through 223.225.225.225.
Just keep it simple..use free ones for 2-3 pages with links to your site. Blogger.com + pages.google.com + wordpress.com etc + mylot + forums..etc there are many many ways..
It doesn't really matter. They're just addresses that are assigned to your domain. ISP's are assigned a block of IP addresses (which are usually contiguous such as 196.0.0.0 through 196.255.255.255). They assign adresses out of this block to domain that host with them. It might matter if your links are all coming from the same block of IP addresses, which could happen when you have multiple domains on shared hosting at one web hoster and you interlink those. But that's just a "might" I don't know of any evidence that confirms or dismisses it.
Also remember G analytics, which is something I didn't realize till later. Our company has several websites, of which a third of them are hosted by different companies. It wasn't intentional, just how it kind of grew from the beginning through various sources. Well, dumba$$ me signs up for GA, and lists all the sites. Some of these sites had links pointing to one, which was trying to target a very competitive term. Looking back, I'm thinking G now see's that I own all the sites, and devalued the links.... which were obviously located in prime text territory. Yeah... smacking myself. But whatever. I need the analytics information anyways, and I'll just go about my merry way.
MrStitch That's very possible. But we need more testers to confirm. It is real possible now that G knows you have access to the site. Important lesson here
That is actually part of the information .... This is historically correct, that when someone needed a certain amount of IP addresses that they were allocated blocks, depending on how big a block an individual (or corporation) needed was dependent on what addresses were allocated. An IP address is made up of 4 octets - an octet is simply an 8 bit binary number, but most humans don't read binary too well and for convenience they are represented by numbers between 0 and 255 (2x2x2x2x2x2x2x2 = 256 or an 8 bit number) A class A Block is an allocation that has a fixed first octect such as 10.x.x.x - and provides around 16 million addresses. A class B Block is an allocation that has a fixed first and second octet such as 172.16.x.x and provides around 65,000 addresses. A class C Block is an allocation that has a fixed first, second and third octet such as 192.168.1.x and provides 256 addresses. Now, with all of the required background we can get back to the original question regarding what are different Class C addresses. Knowing that each Class C has the first 3 octets that are different, then a couple of examples will show what you are looking for. Lets say company 1 was allocated the range 192.168.1.x and choose to used 192.168.1.123 as web server 1 and 129.168.1.234 as another webserver. Company 2 was allocated 192.168.5.x and also chose to use 192.168.5.123 as their web server. Getting a site hosted on different servers by Company 1 puts your sites within the same Class C range, where choosing to host with company 1 and company 2 puts your site in 2 different Class C blocks, even though the last octet in the address may be the same. Where the first 3 octets are the same, regardless of the last octet, you are in the 1 Class C network Block. This actually brings up several points regarding the importance of having your sites on seperate Networks - if we consider that a Class A allocation has about 16 million addresses that are "owned" by the 1 entity, is there any value having your sites hosted on different Class C's (blocks with the first 3 octets the same) within this Class A allocation - as in reality, you would appear to be hosted under the 1 allocation. I guess we can only speculate as to the exact details of the Algorithms that are used to determine when a site is actually somewhere else! * for all examples given I have chosen the private IP address blocks as defined by RFC1918 and these addresses should never be routed on the public Internet.
