301 redirects from old to new pages whit a lot of changes
-
Hello all,
We are going to restyle and change CMS so all the urls will change. We are also updating content, adding much more content to the old pages trying to be more user and SEO friendly.
My doubt is about doing 301 redirects from old to new pages when the content has changed a lot. Does it will mantain the ranking of the page or will crawlers thought that is a total diferent page.
For example: one page new page will change from the old one the url, title, headers, meta description, content text and images.
Should i maintain old content and do the CMS change with the 301 redirects and later change the content, that means a lot of work, or do it all at once?
Thanks in advance
Tomas

The best way to think about this is - what happens if you don't do the 301 redirect from the old pages?
- Any links to those pages will be worthless (as the spiders will end up at a 404 error page, so the search engine will eventually drop the page from the search results)
- Any traffic which comes into those pages will get the same 404 page - so any referral traffic which follows those links in will be lost
- You're forcing the spiders to start from scratch again with your site - to spider and index all the content from the home page
What approach you take depends on your timescales, and how quickly you're going to create the new content. I'm also assuming that maintaining the existing URLs either isn't feasible or there's more value in creating new URLs (e.g. old ones were www.domain.com/index.php?id=3483844 and ones are www.domain.com/category/title-title-title.)
I would be tempted to try and do both at once - just doing the redirect will get people going to the correct URL, but the content will still be regarded as "old" by the search engines. Substantially changed content going onto new URLs will get the benefit of the 301 from the old URL (for referral links etc.), plus a "look again" from the spiders as it will be considered 'fresh'.
There is a very good recent discussion from a couple of weeks ago about new vs. old content http://www.seomoz.org/blog/new-links-old-pages-whiteboard-friday and one from November at http://justinbriggs.org/methods-for-evaluating-freshness

Going from 302 redirect to 301 redirect weeks after changing URL structure
I made a small change on an ecommerce site that had big impacts I didn't consider... About six weeks ago in an effort to clean up one of many SEO-related problems on an ecommerce site, I had a developer rewrite the URLs to replace underscores with hyphens and redirect all pages throughout the site to that page with the new URL structure. We didn't immediately update our sitemap to reflect the changes (bad!) and I just discovered all the redirects are 302s... Since these changes, most of the pages have a page authority of 1 and we have dropped several spots in organic search. If we were to setup 301 redirects for the pages that we changed the URL structure would there be any changes in organic search placement and page authority or is it too late?

301 process, migration to new domain
Hi all! We have an old site wordpress based, with great ranking and PR 7, called www.europe-internship.com which is going to be migrated into our new Django site www.eurasmus.com (specifically eurasmus.com/en/europe-internships)
Intermediate & Advanced SEO | | Eurasmus.com
The new one is a much more advanced version that we will keep developing. We have been migrating the information already but we are planning to apply the 301s in the next weeks to start passing the SEO value to our new site and traffic. We have all the url structures and everything checked and technically we are ready for it.
Therefore, we are almost ready. I have 2 questions: The new site includes more services, like accommodation, information...not only internships. Therefore, should we point the most relevant urls from our previous site to our home to share the value or just to the internships section? I am afraid that if the bounce rate goes higher from the 301 we could loose some value... 2)Should we point all the urls at the same time to the new site? Home, vacancies, blog pages, etc... or start gradually doing it to see how it goes till we make it to all the pages including the home? The old site still makes some money and I am not sure how quick will be to pass the SEO value, so in the way we may loose few thousand euros...We understand that, but we want to check what would be the best in your opinion. Let me know what you think and your opinion! Thank you in advance!0 -
Merging Sites: Will redirecting the old homepage to an internal page on the new site cause issues?
I've ended up with two sites which have similar content (but not duplicate) and target similar keywords, rather than trying to maintain two sites I would like to merge the sites together. The old site is more of a traditional niche site and targets a particular set of keywords on its homepage, the new site is more of an authority site with a magazine type homepage and targets the same set of keywords from an internal page. My question is: Should I redirect the old site's homepage to the relevant internal page on the new website...

...or should I redirect the old site's homepage to the new site's homepage? (the old site's homepage backlinks are a mixture of partial match keyword anchor text, naked URLs and branded anchor text) I am in two minds (a & b!) (a) Redirecting to the internal page would be great for ranking as there are some decent backlinks and the content is similar (b) But usually when you do a 301 redirect the homepage usually directs to the new homepage and some of the old site's links are related to the domain rather than the keyword (e.g. http://www.site.com) and some people will be looking for the site's homepage. What do you think? Your help is much appreciated (and hope this makes sense...!)0 -
Big 301 Redirect Help!
Hey guys I need a little help with setting up a big 301. Background: It's a bit of a mess as the old site is a total mess after being online for 10 years plus. It has html and php pages, and a mod rewrite to redirect old html links to the newer php version of those pages. It's now moving to a new site and as the domain name and URL structure has changed we can't use any fancy regex and have to do a page to page redirect. There are 1500 pages to redirect. However, the old site has thousands of linking root domains, and some of these are to the old html pages (which currently redirect to the php pages) and some to the newer php pages. Question: My initial plan was to leave the mod rewrite and only redirect the php pages. That means 1500 individual redirects instead of 3000 if I individually redirect both the php and html pages. I'm not sure what's best to be honest. We don't really want multiple hops in the redirect (html>php>new site), but surely 1500 redirects is better than 3000! Does anyone have any advice on which option may be best, or even a better option? Thanks 🙂

301 Redirecting an Entire Site
I have a question which has had me thinking for hours..... If SITE A is ranking well on a number of search phrases and you 301 that site to another (SITE B). The site will change on the Google SERPs to the site which you've re-directed to... In this case SITE B. But how do you maintain the rankings of SITE A?. Do you keep the rankings of SITE A forever? Or will your rankings of SITE A (now SITE B) gradually slip as other sites rank higher? As you can no longer edit SITE A does Google take into consideration the content on SITE B and no longer take anything that SITE A had to offer into consideration? SITE B has simply replaced it in the SERPs??...... Please can anybody help? Thanks,

How long do 301 redirects have to stay in place?
For a large retail site we have plenty of "old" pages that are 2-3 years old and still have 301 redirects to a new page. After a search engine has recognized a 301 redirect and dropped the "Old" URL from the index and started displaying the "New" URL, is it safe to delete that old page and thus remove the 301 redirect?
