      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.

            Migrating Subfolder content to New domain Safely

            migration seo ranking

            Hello everyone, I'm currently facing a challenging situation and would greatly appreciate your expertise and guidance. I own a website, maniflexa.com, primarily focused on the digital agency niche. About 3 months ago, I created a subfolder, maniflexa.com/emploi/, dedicated to job listings which is a completely different niche. The subfolder has around 120 posts and pages. Unfortunately, since I created the subfolder, the rankings of my main site have been negatively impacted. I was previously ranking #1 for all local digital services keywords, but now, only 2 out of 16 keywords have maintained their positions. Other pages have dropped to positions 30 and beyond. I'm considering a solution and would like your advice: I'm planning to purchase a new domain and migrate the content from maniflexa.com/emploi/ to newdomain.com. However, I want to ensure a smooth migration without affecting the main domain maniflexa.com rankings and losing backlinks from maniflexa.com/emploi/ pages. Is moving the subfolder content to a new domain a viable solution? And how can I effectively redirect all pages from the subfolder to the new domain while preserving page ranks and backlinks?
            I wish they did, but GSC doesn't offer a solution to migration content from subfolder to a new domain. 😢 Help a fellow Mozer. Thanks for giving a hand.

            Unsolved I have lost SEO Ranking while removing www from domain

            seo search visibility audit

            I have lost search SEO ranking for 4-6 core keywords while removing www from domain switch.
            Referring domain: https://cashforscrapcarsydney.com.au/ Earlier the domain was in the format: https://www.cashforscrapcarsydney.com.au/ But when I checked the search result, search engines had not yet crawled to the new format. Let me know if the server change or any algorithm hit might cause it. Also please share the feedback on - does removing www from the domain losses keyword ranking. Helpful replies are needed.

            Is domain forwarding the same as a 301 redirect?

            domain 301 redirect

            Hi, I have an older domain with some SEO auth for varying pages and a newer domain that is for the brand. Right now there are some 301s for about 13 pages and we are currently moving servers. I was wondering if domain forwarding is the same as writing 301 redirects for each page or is it something different (302)?

            How will changing my website's page content affect SEO?

            Our company is looking to update the content on our existing web pages and I am curious what the best way to roll out these changes are in order to maintain good SEO rankings for certain pages. The infrastructure of the site will not be modified except for maybe adding a couple new pages, but existing domains will stay the same. If the domains are staying the same does it really matter if I just updated 1 page every week or so, versus updating them all at once? Just looking for some insight into how freshening up the content on the back end pages could potentially hurt SEO rankings initially. Thanks!

            Domain Redirect and SSL Cert

            Hi, When redirecting an entire site to another domain, do you have to maintain the SSL certificate? The SSL expires 3 days before the planned redirect. Thanks in advance.

            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. 
            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!

            Does font size affect SEO?

            In the eyes of Google, would the font text size of say a news article affect SEO?  For example, a slightly larger font being easier to read by those with bad eyes?  Accessibility?  If so, what size would be ideal? 10, 12, 14? Your thoughts and suggestions are greatly appreciated.
