Cross linking websites of the same company, is it a good idea
-
As a user I think it is beneficial because those websites are segmented to answer to each customer needs, so I wonder if I should continue to do it or avoid it as much as possible if it damages rankings...

I asked a similar question a few months back so some of the responses on this Moz thread will be of interest to you. Cheers.

Hi Matthew
You'll probably be interested to see what Matt Cutts has to say about the issue: http://youtu.be/x0-jw_PfwtY
In short, a small number of sites that are related are fine to link to each other and won't flag quality guidelines. It sounds like your websites fall under this, so you should be fine.
A problem may occur if there is a gratuitous amount of links or websites all passing PageRank.
If you want to be ultra-safe, you can make the links between the sites nofollow - which will you'll out any chance of a penalty due to interlinking. But I think you'll be fine without this if done sparingly.
Hope this helps.

Sitewide nav linking from subdomain to main domain
I'm working on a site that was heavily impacted by the September core update. You can see in the attached image the overall downturn in organic in 2019 with a larger hit in September bringing Google Organic traffic down around 50%. There are many concerning incoming links from 50-100 obviously spammy porn-related websites to just plain old unnatural links. There was no effort to purchase any links so it's unclear how these are created. There are also 1,000s of incoming external links (most without no-follow and similar/same anchor text) from yellowpages.com. I'm trying to get this fixed with them and have added it to the disavow in the meantime. I'm focusing on internal links as well with a more specific question: If I have a sitewide header on a blog located at blog.domain.com that has links to various sections on domain.com without no-follow tags, is this a possible source of the traffic drops and algorithm impact? The header with these links is on every page of the blog on the previously mentioned subdomain. **More generally, any advice as to how to turn this around? ** The website is in the travel vertical. 90BJKyc

Site Footer Links Used for Keyword Spam
I was on the phone with a proposed web relaunch firm for one of my clients listening to them talk about their deep SEO knowledge. I cannot believe that this wouldn’t be considered black-hat or at least very Spammy in which case a client could be in trouble. On this vendor’s site I notice that they stack the footer site map with about 50 links that are basically keywords they are trying to rank for. But here’s the kicker shown by way of example from one of the themes in the footer: 9 footer links:

The canonical for each page links back to itself. I simply can’t believe Google doesn’t consider this Spammy. Interested in your view.

Advice needed! How to clear a website of a Wordpress Spam Link Injection Google penalty?
Hi Guys, I am currently working on website that has been penalised by Google for a spam link injection. The website was hacked and 17,000 hidden links were injected. All the links have been removed and the site has subsequently been redesigned and re-built. That was the easy part 🙂 The problems comes when I look on Webmaster. Google is showing 1000's of internal spam links to the homepage and other pages within the site. These pages do not actually exist as they were cleared along with all the other spam links. I do believe though this is causing problems with the websites rankings. Certain pages are not ranking on Google and the homepage keyword rankings are fluctuating massively. I have reviewed the website's external links and these are all fine. Does anyone have any experience of this and can provide any recommendations / advice for clearing the site from Google penalty? Thanks, Duncan

Suspicious external links to site have 302 redirects
Hi, I have been asked to look at a site where I suspect some questionable SEO work, particularly link building. The site does seem to be performing very poorly in Google since January 2014, although there are no messages in WMT. Using WMT, OPenSiteExplorer, Majestic & NetPeak, I have analysed inbound links and found a group of links which although are listed in WMT, etc appear to 302 redirect to a directory in China (therefore the actual linking domain is not visible). It looks like a crude type of link farm, but I cant understand why they would use 302s not 301s. The domains are not visible due to redirects. Should I request a disavow or ignore? The linking domains are listed below: http://www.basalts.cn/

Why website isn't showing on results?
Hello Moz! Just got a quick question - we have a clientcalled and for some reason they just aren't showing up in the search results. It's not a new domain and hasn't been penalised (or has reason for penalty). All the content is fresh and has no bad back links to the site. It is a new website and has been indexed by Google but for even for branded search terms, it just doesn't show up anywhere on page 1 (i think page 4). Any help or advise is great appreciated is it's doing my head in. We are using www.google.com.au. Kindest Regards

Why do websites use different URLS for mobile and desktop
Although Google and Bing have recommended that the same URL be used for serving desktop and mobile websites, portals like airbnb are using different URLS to serve mobile and web users. Does anyone know why this is being done even though it is not GOOD for SEO?
