Similar Sites on Same Class C
-
Hi there,
I asked a similar question a while ago - please pardon the dupe. I figured being more specific may help.
Here's the scenario:
I have two customers which sell very similar products. They both host with me so they are both on the same class C of ip addresses. Content on sites is similar due to the nature of the business/industry.
- There are no links between the two sites - they do not link to one another
- The HTML is about 50% the same, content near zero other than site structure. They have similar category structures.
Question - could being on the same Class C adversely effect rankings of either. One site did particularly well until Panda came around and it's sloooowly coming back. Some advise has been given to the client that the IPs being on the same Class C is killing rankings. I am trying to either validate or refute the claim.
All help/feedback appreciated.

Chris,
So far as I know this is not an issue. If I'm not mistaken, you have it set-up so that the registrar is pointing multiple domains to your host IP and you're maintaining all of your sites within one cPanel (or one parent directory).
If that's the case, it's OK. I asked a similar question several months back and the general consensus seems to have been that it's not going to effect rankings as long as a majority of the links are not coming from the same IP block. I think this kind of piggybacks on the whole 'link farming' problem that was popular amongst Black Hat SEOs back in 2009-2010.
For some additional insight, check out the discussion here: http://www.seomoz.org/q/managing-multiple-websites-via-add-on-domain.

As far as I know, the Class C issue is only relevant for linking. It's widely suspected that links from domains on the same Class C IP are less valued, since that's a good indicator of a "fake" link (i.e. a backlink that the site owner created, rather than a true editorial backlink).

I have a metadata issue. My site crawl is coming back with missing descriptions, but all of the pages look like site tags (i.e. /blog/?_sft_tag=call-routing)

Merging B2B site with B2C site
Hi, A mobile phone accessory client of ours has a retail site (B2C) and a trade site (B2B). The retail site does pretty well and ranks highly for a number of terms. The trade site doesn't really rank for anything as they don't optimise it. They would like to merge the two sites and allow trade customers to log-in and purchase goods in bulk for their business. If they were to merge the trade site into the already successful consumer site, what would be the best way of doing this and what, if any, implications would it have on the organic visibility of the B2C site? Would it be possible to target retail and trade customers on one website? Cheers, Lewis

Meta refresh for news site?
We have a news site that uses a meta refresh (<meta < span="">http-equiv="refresh" content="600" /> across all content. I understand the reasoning on the homepage and am trying to decide of the cons of using this (slows page, is it treated differently and loses pagerank/link ..) Does anyone have experience with meta refresh being a negative thing or does it no longer matter?</meta <>

There is no change of address pending for your site
Hi everyone. Google has recently started using our old .net instead of .com in the SERPS. I went to do a change of address for the old http://www.sqlsentry.net and it gives me the "There is no change of address pending for your site." I've tried for both www and non-www and still get the same result. All pages seem to be redirecting to the new site with no issues. Is there anything else I can do to change this? Or is there a step I'm missing? Thanks!

What is wrong with my once highly ranked site?
Hello, I'm really desperate for some help. I believe I've been hit by Panda as traffic started diminishing late March for my 6 year old website. I've never had a sharp drop, only gradual. I've lost a load traffic since then. I did change shopping carts in June since I had a a canonical issue from my old cart that couldn't be corrected. The old cart also did not allow me to have unique product titles and the urls were garbled with letters, numbers, etc... I know Panda did not like that. I've made several changes (cleaned up broken links, added more content to my site, added Disallow: /search/ and Disallow: /search to my robots.txt file to avoid duplicate content from my search box.) My most prized keywords (tutu and tutus) are on page 15 or so of Google now, when they used to be on page 1 or 2 at the worst. Other good ones are slipping too. I do need to hire an SEO to optimize my titles eventually as I believe my they are still a bit stuffed but before I do that, I am just trying to get the other stuff done first. My main questions are this... Do any of you see something else that looks bad to you in the eyes of Google? I'd love the cold, hard truth as I'm pretty desperate for my site to recover, if at all possible. Thank you in advance! Here is my site: http://alturl.com/mvmux

Best practice for site maps?
Is it necessary or good practice to list "static" site routes in the sitemap? I.e. /about, /faq, etc? Some large sites (e.g. Vimeo) only list the 'dynamic' URLs (in their case the actual videos). If there are urls NOT listed in a sitemap, will these continue to be indexed? What is the good practice for a sitemap index? When submitting a sitemap to e.g. Webmaster tools, can you just submit the index file (which links to secondary sitemaps)? Does it matter which order the individual sitemaps are listed in the index?

Building a mobile site.
We are building a mobile site that will be launching in another month. I’m concerned that the mobile site will start catabolizing our traditional rankings. Is there a way to keep this from happening? Should we utilize the cross domain canonical tag and point back to the traditional site URLs?
