Best method of redirecting http to https on homepage

[PeterAlexLeigh]

Hi everyone,

I'm looking to redirect all http requests to https for a site's homepage. It only needs to be for the homepage, not site wide.

What's the best method of doing this without losing pagerank or ranking?

I'm using IIS7.5 so I've been looking at a URL Rewrite or possibly this ASP.Net solution;

Or is a simple 301 or 302 (for some reason Microsoft's site says to do a 302 re-direct, though I'm not sure if this is great from an SEO perspective?) re-direct from http version to the https version the best method?

Also if the solution retained the URL query string that would be even better!

Any help appreciated! Thanks

Are you securing a lead-gen form? One thing to test first - have you done an A/B test of the in-page form vs. a large call-to-action button? I've seen testing go both ways. Sometimes, the in-page form drives more leads, but sometimes a clear call-to-action to a separate form is better (really seems to depend on the form and the industry). If the call-to-action works just as well, it would be much easier to secure the stand-along form than your home-page.

Going secure full-site would help solve some problems, although you do need full-site 301-redirects then, and you've got to make sure your servers can handle it (https: needs additional overhead). It's really tough to tell without knowing the nature/scope of the site.

I'd be happy to close the private question, but if you want to dive into details there, it might not be a bad idea. Seeing the site would really help, since this is a tricky issue.

Ooo, doesn't sound great.

Do you think if I was to do this it would be better to convert the whole site to HTTPS and enforce it site wide?

(I actually posted a private question on this as well hoping you'd answer it, but you've done it here! - can I close the private one??)

Thanks

301 is probably best here. There are two tricks here, though, and it can get messy:

(1) You'll need to link to the HTTPS version in your internal links as well.

(2) If you use relative links (like "/about.aspx"), then all the navigation links from your secure home-page will cause Google to crawl the rest of the site with HTTPS, possibly creating mass dupe content.

Practically, there's a fair amount of risk in just securing your home-page, and it goes beyond the home-page itself. I'd proceed with caution and really evaluate the pros and cons.

For SEO the 301 is the best and simple solution

Naghirniac - thanks for your answer.

Granted, but which is the best for SEO?

I'm thinking, surely I can just do a simple 301?

Shelly,

There are tree methods, all with their benefits and difficulties. They are: Redirect via a landing page, Redirect via a custom error and Redirect via URL manipulation.
