Redirection of 100 domain to Main domain affects SEO?
-
Hi guys,
An email software vendor managed by a different area of my company redirected 100 domains used for unsolicited email campaigns to my main domain. These domains are very likely to get blacklisted at some point. My SEO tool now is showing me all those domains as "linking" to my main site as do-follow links. The vendor states that this will not affect my main domain/website in any way. I'm highly concerned. I would appreciate your professional opinion about this. Thanks!!

You're right to be concerned. These backlinks from spammy domains can hurt your SEO. Explain the situation to your company's SEO team and request disavowing the links to protect your main domain's reputation.

Most probably, these are PBN links. They may not impact your site immediately, but they will affect it at some point. In this case the Moz spam score will increase and you'll see a lot of broken links to your site. You should ask your vendor to disavow these links as soon as possible.

Using a Reverse Proxy and 301 redirect to appear Sub Domain as Sub Directory - what are the SEO Risks?
We’re in process to move WordPress blog URLs from subdomains to sub-directory. We aren’t moving blog physically, but using reverse proxy and 301 redirection to do this. Blog subdomain URL is https://blog.example.com/ and destination sub-directory URL is https://www.example.com/blog/ Our main website is e-commerce marketplace which is YMYL site. This is on Windows server. Due to technical reasons, we can’t physically move our WordPress blog to the main website. Following is our Technical Setup Setup a reverse proxy at https://www.example.com/blog/ pointing to https://blog.example.com/ Use a 301 redirection from https://blog.example.com/ to https://www.example.com/blog/ with an exception if a traffic is coming from main WWW domain then it won’t redirect. Thus, we can eliminate infinite loop. Change all absolute URLs to relative URLs on blog Change the sitemap URL from https://blog.example.com/sitemap.xml to https://www.example.com/blog/sitemap.xml and update all URLs mentioned within the sitemap. SEO Risk Evaluation We have individual GA Tracking ID and individual Google Search Console Properties for main website and blog. We will not merge them. Keep them separate as they are. Keeping this in mind, I am evaluating SEO Risks factors Right now when we receive traffic from main website to blog (or vice versa) then it is considered as referral traffic and new cookies are set for Google Analytics. What’s going to happen when its on the same domain? Which type of settings change should I do in Blog’s Google Search Console? (A). Do I need to request “Change of Address” in the Blog’s search console property? (B). Should I re-submit the sitemap? Do I need to re-submit the blog sitemap from the https://www.example.com/ Google Search Console Property? Main website is e-commerce marketplace which is YMYL website, and blog is all about content. So does that impact SEO? Will this dilute SEO link juice or impact on the main website ranking because following are the key SEO Metrices. (A). Main website’s Avg Session Duration is about 10 minutes and bounce rate is around 30% (B). Blog’s Avg Session Duration is 33 seconds and bounce rate is over 92%

Combine .com and .co.uk domain? So forward .co.uk to .com for SEO?
Hello, A new client of mine has an .com and an .co.uk domain. Both the same content (and they don't have the capacity to make specific content on both domains). I am thinking building al domain authority to 1 domain. In this case the .com domain.
Intermediate & Advanced SEO | | Seeders
And forward the .co.uk to this .com domain.
In this way, the .com will rank in both UK as in other English speaking countries, right? Or not?
Or should I use the rel="alternate" hreflang="x" tag? I am not sure. But I do know big brands rank high in the Netherlands with .com domains (for example booking.com). Looking forward on feedback on best practices here... Thanks!0 -
What are the effects of having Multiple Redirects for pages under the same domain
Dear Mozers, First of all let me wish you all a Very Happy, Prosperous, Healthy, Joyous & Successful New Year ! I'm trying to analyze one of the website's Web Hosting UK Com Ltd. and during this process I've had this question running through my mind. This project has been live since the year 2003 and since then there have be changes made to the website (obviously). There have also been new pages been added, the same way some new pages have even been over-written with changes in the url structures too. Now, coming back to the question, if I've have a particular url structure in the past when the site was debuted and until date the structure has been changes thrice (for example) with a 301 redirect to every back dated structure, WOULD it impact the sites performance SEOwise ? And let's say that there's hundreds of such redirections under the same domain, don't you think that after a period of time we should remove the past pages/urls from the server ? That'd certainly increase the 404 (page not found) errors, but that can be taken care of. How sensible would it be to keep redirecting the bots from one url to the other when they only visit a site for a short stipulated time? To make it simple let me explain it with a real life scenario. Say if I was staying a place A then switched to a different location in another county say B and then to C and so on, and finally got settled at a place G. When I move from one place to another, I place a note of the next destination I'm moving to so that any courier/mail etc. can be delivered to my current whereabouts. In such a case there's a less chance that the courier would travel all the destinations to deliver the package. Similarly, when a bot visits a domain and it finds multiple redirects, don't you think that it'd loose the efficiency in crawling the site? Ofcourse, imo. the redirects are important, BUT it should be there (in htaccess) for only a period of say 3-6 months. Once the search engine bots know about the latest pages, the past pages/redirects should be removed. What are your opinions about this ?

How does badly formatted HTML affect SEO?
Our website uses a custom built CMS, but uses a fairly standard WYSIWYG text editor. I've looked at some of the code it produces, and it's not pretty. My gut feeling tells me that this extra bloat is bad for SEO. Am I right in thinking that Google doesn't look kindly upon badly formatted and bloated HTML? Thanks,

How long should a domain redirect take?
Hi, I know that this is a 'How long is a piece of string?' type question but at what point should the ranking value of site A pass over to site B following a domain 301 redirect? I have shifted a domain over to a new URL, same hosting server, same IP address. I haven't made any URL changes or any content changes other than to change the site logo to match the new domain name. Domain B is basically an exact clone of domain A. I have redirected Domain A to domain B using the following line at the top of the .htaccess file:- Redirect 301 / http://www.newdomain.com/ I have submitted a sitemap for the new domain via google webmaster tools. It looks like the original domain as been completely indexed by google following the redirect as all rankings have been dropped from the results and there are no results for a site:olddomain.com search. Surely the rankings should have switched over at this point? Any help would be much appreciated.

Subdomains and SEO - Should we redirect to subfolder?
A new client has mainsite.com and a large numer of city specific sub domains i.e. albany.mainsite.com. I think that these subdomains would actually work better as subfolders i.e mainsite.com/albany rather than albany.mainsite.com. The majority of links on the subdomains link to the main site anyway i.e. mainsite.com/contactus rather than albany.mainsite.com/contactus. Having mostly main domain links on a subdomain doesnt seem like clever link architecture to me and maybe even spammy. Im not overly familiar with redirecting subdomains to subfolders. If we go the route of 301'ing subdomains to subfolders any advice/warnings?
