Changing website framework: Any negative SEO ramifications?
-
Hello! We have a website that is built using Asp.net. My colleague and I are wondering whether or not changing the framework from Asp.net to php or html would have any negative impact on current rankings.
My colleague was told by an SEO company that doing this would have a big negative effect, but we just can't see why that would be. The URLs of the site do not have an .asp extension, so we don't feel there would be any issues with 404s after the migration. The content, meta data and URL structure would remain the same.
We posted this question in the Webmaster Central Forum and were told by a top contributor that it wouldn't have any negative impact, but we wanted a second opinion here. Thanks!

I think Hutch42 is right. If your urls have no file extensions on them (.asp, .php, .htm), you really shouldn't see any dip from merely changing over.
It would be worth triple-checking about the extensions, though. We changed our site over a few years back and saw a dip in some key lead-generating pages that had extensions on them.
One place you may see a difference is with load times. Your pages' code structure will likely change. And .NET/IIS sometimes has different speeds than a LAMP stack even with the same content.

There should be no issue as long as you do everything that you have planned.

Two Different IP address pointing to my website, does it will effect my website from SEO point of view
Due to some reason my website https://xyz.com is not redirecting to my main website domain - https://www.xyz.com so our tech team suggested - we will have the non-www name on a different IP and we'll 301 redirect that to the https://www.xyz.com. if it works does it will effect our website from SEO point of view? please let me know.

Redirecting M Dot Mobile Website to Responsive Design Website Questions
Hi amazing Moz community 🙂 Couldn't find this question anywhere, and knew this was the place to ask! We are helping a client redirect an M Dot website to a Responsive Design website. We want to retain our mobile rankings for keywords. Three questions - We should use 301 redirects from the M Dot website to the new website correct? (not 302s?) How long does it take for Google to understand that we have launched a responsive website? Can we remove the 301 redirects after a few days (if the M Dot website interferes/breaks the new Responsive website)? We have verified an account on Google Search Console for the M Dot website, along with a mobile sitemap that has been submitted and verified. What should we do with this M Dot GSC account? Just delete it? Or keep it and upload the NEW XML Sitemap with the new WWW links (because the website is responsive). THANK YOU!

Website not ranking
Firstly, apologies for the long winded question. I'm 'newish' to SEO We have a website built on Magento , www.excelclothing.com We have been online for 5 years and had reasonable success. Having used a few SEO companies in the past we found ourselves under a 'partial manual penalty' early last year. By July we were out of penalty. We have been gradually working our way through getting rid of 'spammy' links. Currently the website ranks for a handful of non competitive keywords looking at the domain on SEM RUSH. This has dropped drastically over the last 2 years. Our organic traffic over the last 2-3 years has seen no 'falling off a cliff' and has maintained a similar pattern. I've been told so many lies by SEO companies trying to get into my wallet I'm not sure who to believe. We have started to add content onto all our Category pages to make more unique although most of our Meta Descriptions are a 'boiler plate' template. I'm wondering.... Am I still suffering from Penquin ? Am I trapped by Panda and if so how can I know that? Do I need more links removed? How can I start to rank for more keywords I have a competitor online with the same DA, PA and virtually same number of links but they rank for 3500 keywords in the top 20. Would welcome any feedback. Many Thanks.

Negative seo problem
Hello, Someone attacked our website with negative SEO and our website fell drastically. If i use bing webmaster tools link explorer i see dozens and dozens spam links but if open a link i don't find this link in that website. Is it possible that someone added the links and then remove thouse links when we got hit? Or is it possible to hide the links that they don't show up on webpage but they are still there? How can i use Google disavow links tool if there is no links in thouse websites but Bing link explorer shows spam domains pointing to our website. BR, T

Links from a website or a subdomain, which would generate more benefits in terms of SEO?
I have a customer who just bought a domain (and the full website) of a competitor and decided that they will no longer update the website purchased. The website of my client has a Domain Authority = 50 and DA of the website purchased is 45. Each of them was registered by different companies and are on different servers too.
Intermediate & Advanced SEO | | marciofelias
The reason for my message is that by being registered by different companies and are in differrent servers I can use the site purchased as a way to make link building to the main website (one way link buiding only from the website purchased to the main website), but I can put the website purchased as a subdomain of the main website and agregate content to the main website.
In your opinion which would generate more benefits in terms of SEO to the main website? Links from the website purchased or put this website as a subdomain to the main website?0 -
Mobile SEO? Do we need it or not?
Hi Guys, I am about to start to redesigning a new mobile website and am curious if mobile SEO is actually having an affect or not. The site I am doing the redesign for, already has a very well optimized desktop site and has an existing mobile website with no optimization. The mobile website is ranking well in Mobile search so I am curious why I I would need to optimize the new mobile website properly, especially when the mobile website has a canonical tag for its desktop counter part? Love to get everyone's thoughts on this & where they see mobile SEO going in the next 12 months.

Expiring URL seo
a buddy of mine is running a niche job board and is having issues with expiring URLs. we ruled it out cuz a 301 is meant to be used when the content has moved to another page, or the page was replaced. We were thinking that we'd be just stacking duplicate content on old urls that would never be 'replaced'. Rather they have been removed and will never come back. So 410 is appropriate but maybe we overlooked something. any ideas?
