Redirecting 301 Redirects -- Will Search Engines Notice?
-
Hello Mozzers,
We're currently evaluating a client site where the previous web developer redesigned the site and got lazy, 301 redirecting hundreds of pages to the home page instead of to their respective new URLs. Ugh.
In any case, we will probably fix this for the sake of implementing best practices. But I am curious how search engines treat 301'd URLs, as they are supposed to be permanent redirects. Will search crawlers ever visit the old URLs again to find that we've re-redirected them? Or have they written them off as moved to the home page for good, meaning that there's no way to direct the authority of the previous URLs to their rightful targets?
Thanks!

Recently I just did a domain change of a company website, did a 301 redirect for each page and after 2 months everything were fine and keeping the same position in SERP it previously had (some even gained rank)
The only thing is, the site was quite small, with around 15 links, so was a easy job to do.

The message is: This move is permanent, however, crawlers will always follow links and always bump into old version of the page so there is a chance that they may pick up that 301 is changed or removed. Google (Matt Cutts) also stated that they follow 301 chains but they do not guarantee that it would work well if you have many 301s in the chain. Search engines obey 301 much more firmly than rel canonical for instance as 301 is a directive and canonical is a "hint" as he describes it.
To answer your specific question, if you set new redirection rules they will be picked up. That said I have had cases in the past where it took Google more than 6 months to clean up messy redirection situations and some cases where they have completely failed it at. In your case it should be all fairly straightforward.

Https Implementation - Weird Redirection After Putting 's' in http://
Hi Mozers, I have come across some websites with their https version going to a totally different website. For example, http://www.samplesite1.com will load fine but when the protocol is changed to https (https://www.samplesite1.com) it will go to a total different domain say, https://www.samplesite2.com How does this happen, in technical sense? In the warning from browser, it says the the security certificate is from the other website but I would like to understand how this happens and how it impacts SEO. I seem to be not able to understand the relationship of this error and SEO impact. Thanks in advance for your response. Malika

Help with redirects
Our travel company used to maintain a set of country destination guides on our site, under the www.oursite.com/destinations/country folder path. Because we offer tours all over the world, we used these pages as high-level guides to each country so a prospect could get a sense of the highlights of those destinations. These pages operated as landing pages too. Unfortunately the pages became stale and unfocused, and we decommissioned them. In order to bring them down, we put a 301 redirect on these URLs, pointing them to a faceted-search page that showed all of our tours to that country, with URLs: www.oursite.com/trips/country. These faceted-search pages were pulling double duty as both search pages and landing pages, which isn't ideal (from a users perspective). We are now in the process of redoing our search function and we'll need to move the search URLs off /trips/ and onto /search/. Within this transition, we are going to re-launch destination guides, and I think the best place for them will be back on the old /destinations/ subfolder. So, a few moving parts here. My question: Do you see problems with reversing the redirect path completely? Ie. where we currently redirect /destinations/country to /trips/country, we are now proposing to redirect /trips/country to /destinations/country. Our concern in this equation is that, over the last few years, we've built up significant link volumes and equity to the /trips/ pages, and we don't want to lose that.

Page Title or Search Friendly Urls?
We are currently auditing our website as part of our SEO strategy. One item which hascome up is the importance of search friendly urls against the search engine friendly page titles. Do url's or page titles carry more relevance than the other in search engines? Obviously the ideal would be to have both to maximise search impact but do either carry more importance. Thanks

The primary search keywords for our news release network have dropped like a rock in Google... we are not sure why.
Hi, On April 11th, a month after the farmer update was released for U.S. users of Google, the primary keywords for ALL our sites significantly dropped in Google. I have some ideas why, but I wanted to get some second opinions also. First off, I did some research if Google did anything on the 11th of April... they did. They implemented the farmer update internationally, but that does not explain why our ranks did not drop in March for U.S. Google users... unless they rolled out their update based on what site the domain is registered in... in our case, Canada. The primary news release site is www.hotelnewsresource.com, but we have many running on the same server. EG. www.restaurantnewsresource.com, www.travelindustrywire.com and many more. We were number 1 or had top ranks for terms like ¨Hotel News¨, ¨Hotel Industry¨, ¨Hotel Financing¨, ¨Hotel Jobs¨, ¨Hotels for Sale¨, etc... and now, for most of these we have dropped in a big way. It seems that Google has issued a penalty for every internal page we link to. Couple obvious issues with the current template we use... too many links, and we intend to change that asap, but it has never been a problem before. The domain hotelnewsresource.com is 10 years old and still holds a page rank of 6. Secondly, the way our news system works, it´s possible to access an article from any domain in the network. E.G. I can read an article that was assigned to www.hotelnewsresource.com on www.restaurantnewsresource.com... we don´t post links to the irrelevant domain, but it does sometimes get indexed. So, we are going to implement the Google source meta tag option. The bottom line is that I think we put too much faith in the maturity of the domain... thinking that may protect us... not the case and it´s now a big mess. Any insight you can offer would be greatly appreciated. Do you think it was farmer or possibly something else? Thanks, Jarrett
