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.

My website is constantly decreasing
For few weeks ago my website is constantly decreasing in search position. I lost keywords and is gooooing down.
Technical SEO | | Dan_Tala
Although it is well rated on several on page and off page seo verification software that I have tried.
I checked Google search console and Analytics and found no major problems. However… from one day to another it keeps going down.
I also checked what the main competitors are doing and they are not doing well, at all.
The main competitor actually has a creepy website. Totally devoid of onpage or offpage SEO but with an enormous number of backlinks. And of a very bad quality, which should disqualify it, still…
Few weeks ago I changed something.
In the pages I had H1, 4xH2, no H3 and an H4 without content.
An unnatural H tag structure.
Now I have H1, H2, H3, 3xH4, with the coherent information.
Theoretically, Google should have been “happy” or I’m missing something. I use a SAAS platform.
I just found out that they made changes to the keywords (tags).
I am selling toner cartridges for printers.
So…
The tags are printer models and generate a url in which they have the products.
Ex. https://www.sertit.ro/cartus-imprimanta-cilindru-color-hp-laserjet-pro-m-177fw goes to the products for that printer model.
The question is… should I make tag canonical?
Is it possible for products to loose so much in Google search?0 -

Businesses That Have 2 Trading Addresses
Hi, I have a quick question regarding Local SEO. We have a building company that operates from 2 addresses, about 70 miles apart. When we changed the address in the footer of our website to a different registered office the rankings for that local area bombed. What I would like to know is if there is a way I can properly mark up the site so that Google recognizes the same business works from 2 locations. Thanks

Would adding an SSL certificate help my website?
SSL certificates can obviously be a used as a ranking factor by Google, but would a site with no need for an SSL certificate notice a gain by adding one? Is it possible to demonstrate you have an SSL certificate without having some https pages on your site?

How do I resolve Twin domains? redirect website.com to www.website.com?
I am new to this website. Tried to run a campain and got a warning that website.com resolves to www.website.com which hinders SERP by competing for Keyword indexing!. (website is my domain name) Would appreciate help with this. Thanks. S.H. PS: here is the exact wording of error : We have detected that the domain www.yfvaccine.com and the domain yfvaccine.com both respond to web requests and do not redirect. Having two "twin" domains that both resolve forces them to battle for SERP positions, making your SEO efforts less effective. We suggest redirecting one, then entering the other here.

Mobile Google Not Indexing Mobile Website
Google currently does not index our mobile website. It has the WWW website in it's index. When a user from a mobile phone clicks on a mobile search result for WWW we redirect them to our mobile website. This is posing problems for us as our mobile website is a fraction of the # of pages/sections as our WWW. So for example, mobile search results show that we have a "careers" section; but that's not the case for the mobile website. As a result a user gets a 404. How do we force mobile Google to index our mobile website instead of our WWW?
