Will updating our site from ASP .NET 3.5 to ASP .NET 4.0 negatively affect SEO?
-
I've checked out some of the other posts related to .NET upgrades, but none specifically address ASP .NET 4.0.
I understand that there are many advantages to upgrading, but as with any change made to site code I want to be 110% positive that this upgrade will not affect how Google ranks my client's pages.
Since the URL extension isn't changing (will remain .aspx), I'm thinking that there won't be much of an affect on SEO at all. In fact, I'm making the argument that the upgrade will only improve page rank.
Anyone go through this upgrade and experience any immediate benefits or disadvantages?
Thanks for your help!

If your ASP code is used primarily for dynamically generating HTML (at or before page load), and the HTML isn't changing, and your URLs are staying the same, I can't see how SEO would be affected or why you'd run into any problems.
If the upgrade includes code modifications that change the way the pages load, however, it could affect SEO depending on how that's handled.

Login to see more (some text hidden by CSS height and jquery) will it ruin SEO?
Hey SEO masters! I have a website that is smashing it for SEO in Australia. In an effort to increase a user base I want to make it so only logged in users can see all the content. So today, I launched a new feature hiding content using CSS 'height:' property. The content is obviously still there and if you were a developer you could easily 'inspect element' and remove that CSS style to see everything... There are a few other tweaks i made for logged out users, but that only affects some json. Question: will this affect my SEO rankings? Here is a direct example: https://www.fishingspots.com.au/s/perth if you sign up, there is about 1400words of content.

Conversion drop after site move
Have just migrated current and active site to Magento 1.9 and a new hosting package (dedicated and reasonably powerful for what we need). But we seem to have had a drop in conversion rate. I don't really know whether it's anything to be concerned about the moment. I've set up extensive server level 301 redirects for old pages. Would be glad of any thoughts? Thanks you

SSL, SEO, and Site Migration question
When migrating a site to a new url and one where the old url had no https and the new url will be full https does it matter if the 301 redirect points at http://thisisthenewsite.com ? Meaning, should the new site have the ssl / https up prior to redirecting the old site? Does it matter if you redirect the old site to http://thisisthenewsite.com or https://thisisthenewsite.com? Since the site will force to https anyway?

Moving the site and Rebranding
I was wondering about moving the site and rebranding. If one was to move their site with a good Google Page Rank, how long should you take before doing the updated redesign, cms update and url restructuring? I know that Matt Cutts has said that you should move BEFORE doing your redesign but I don't remember him saying how long you should take for each step. Thanks!

How to correct error in customized posttype WP site
Hi folks Can anybody help me. I foolishly, dogedly followed a Lynda.com tutorial for developing an 'online portfolio in WP'. Little did I know that my initial assumption - to use the 'twenty twelve' rather than the 'twenty eleven' theme would land me in such deep water. I was attempting to learn php on my own. All went well, until, --- the index page for the customized post type. Now I have two beautiful customized posttypes, 'companies' 'coverage' and no idea how to create an index page for either. I can't do the next step! I have tried every permutation - changing the permalink settings, changing them back, desperately searching for any handle to the nebulous links within the menu section. The only thing I can do (and have done for now) is to link the menu item 'company' and the menu item 'coverage' to a single post. Then the poor visitor has to scroll through the posts individually. I tried contacting the tutor and Lynda.com, to no avail! I have searched forums and found this is a common problem, but because I am so confused and novice to php they might as well be speaking Chinese. To compound my problems, looking through 'Wordpress SEO' for Yoast, I am painfully aware I can't go to the first basic step and fix the peramilinks to 'Postname' as that just makes my flakey menu collapse like a pack of cards. Help!

How does a Responsive Site kill SEO?
How does a Responsive Site poentially kill SEO? I've seen a few feeds on twitter how a website took a rankings dive after implementing a Responsive theme; yet, it's not clear to me what is actually going on within a Responsive site that would cause the SEO rank to tank? I can only speculate that it introduces a bunch of 404 errors, or that it changes all of the URLs into gibberish, so you loose all of the links coming into your website if not 301'ed? Can someone clarify, what are the actual mechanical issues on a Responsive website that becomes a concern to SEO? Thanks.

Changing from Squarespace to Wordpress - Will I Lose My Rankings?
I have a friend who has a squarespace site that is giving him lots of trouble. For one, even though it is supposed to redirect to GreenSpaceConstruct.com...Bing and Yahoo don't seem to recognize this domain. Instead, they show greenlightconstruct.squarespace.com in the serp's. Oddly, Google shows the site as GreenSpaceConstruct.com. The site is ranking well for some terms. I'm afraid that converting to wordpress will hurt his rankings in the short term. If bing and yahoo are crawling this squarespace domain, and he moves it...is there a way not to just completely lose the rankings? Thanks for any thoughts. Much appreciated! Josh

Recommendation for a company to make a site more mobile friendly?
Hiya, We have a client who uses us for SEO, and a separate company for web development. They have a fairly large site on a bespoke CMS. They're happy with the site, but the user experience on mobile devices is not right. Can anybody recommend a company specializing in that area? Preferably a UK company but not essential. Thanks 🙂
