Is there a limit for 301 redirection in htaccess file?
-
For the SEO perspective, there is a limit for the number of 301 redirection inside the htaccess file?

Hi Naghirniac,
This is a very general question. As far as a limit the answer would have to be no, there is no limit. However, what is going on here? Are you rebuilding a very large website and attempting to consolidate pages? Be sure you are pointing old URLs to pages that are very relevant to the old content or you will surely see rankings fall for those pages. Also, do the old URLs have lots of backlinks? You may consider contacting the webmasters of the websites that link to your old pages and told of the change so they can update their links to point to the new pages, at least for the more important links – the 301’s will pass most of the juice, but not all.
Hope this helps,
Vizergy

The simple answer is no. Let's say you have page A and 301 it to page B. As soon as Googlebot gets the 301 (might take a bit longer but for argument's sake we'll say it's instant) it drops page A and indexes page B. As the ranking process moves along (which is slower than indexation) most, if not all, of the PR that A had is now moved to B.
Google can't read your htaccess file (Apache will not show any page with a period as the first character in the filename for security reasons) and I've not heard of any long term penalties from changing URLs. Just realize that there is a gap (days or weeks) between the time that Google notes A moved and B is ranked like A was.

Has anyone ever tested to see if having an ads.txt file provided any SEO lift?
I know that the ads.txt system is designed to prevent ad fraud and technically has nothing to do with search. That said, the presence of such a file would seem to be an indicator of overall site quality because it would show that a site owner wants to participate in a fraud-free system. Has anyone ever tested that? If so, they don't seem to have published their results. Maybe it's a secret weapon that some pros are using and not sharing?

Spanish website indexed in English, redirect to spanish or english version if i do a new website design?
Hi MOZ users, i have this problem. We have a website in Spanish Language but Google crawls it on English (it is not important the reasons). We re made the entire website and now we are planning the move. The new website will have different language versions, english, spanish and portuguese. Somebody tells me that we have to redirect the old urls (crawled on english) to the new english versions, not to the spanish (the real language of the firsts). Example: URL1 Language: Spanish - Crawled on English --> redirect to Language English version. the other option will be redirect to the spanish new version, which the visitor is waiting to find. URL1 Language: Spanish - Crawled on English --> redirect to Language Spanish version. What do you think? Which is the better option?

Website Redesign - What to do with old 301 URLs?
My current site is on wordpress. We are currently designing a new wordpress site, with the same URLs. Our current approach is to go into the server, delete the current website files and ad the new website files. My current site has old urls which are 301 redirected to current urls. Here is my question. In the current redesign process, do i need to create pages for old the 301 redirected urls so that we do not lose them in the launch of the new site? or is the 301 command currently existing outside of our server so this does not matter? Thank you in advance.

Do I need to 301 redirect www.domain.com/index.html to www.domain.com/ ?
So, interestingly enough, the Moz crawler picked up my index.html file (homepage) and reported duplicate content, of course. But, Google hasn't seemed to index the www.domain.com/index.html version of my homepage, just the www.domain.com version. However, it looks like I do have links going specifically to www.domain.com/index.html and I want to make sure those are getting counted towards my overall domain strength. Is it necessary to 301 redirect in the scenario described above?

How to rewrite/redirect a folder name with .htaccess
I have a folder in my site that I want to rename. I don’t want to just rewrite the URL and keep my old folder name, I want to change the folder name and then do whatever is necessary with .hataccess to not lose search engine rankings. The folder name I want to change has a space in it and also is misspelled (whoops x2) Example. Mysite.com/old foldr/page.html Mysite.com/newfolder/page.html How would I go about doing this with .htaccess? Do I just switch the folder name on my server and then set up a redirect, or do I do a rewrite? Sorry now familiar with the terms or .htacces. Thanks all

Display a message after 301 redirect.
I know this one is a little more technical than pure SEO, but it somewhat ties in. I'm redirecting 2 sites to one. The companies have combined, and I've imported all their content that has been created, and the url mapping is set up correctly. So it currently is set up like this: A.com --> C.com
Web Design | | WilliamBay
A.com/blogpost-1 --> C.com/blogpost-1 B.com --> C.com B.com/blogpost-20 --> C.com/blogpost-20 What i would like is some method a redirect when landing at C.com or C.com/blogpost-XX. And in turn display a message in a DIV so I can style it. And yes, I have nothing better to do on a Friday night 🙂0 -
Optimal redirect configuration from a misspelled domain that we own.
We have a handful of inbound links to www.t-chek.com (note the hyphen). Our normal site is www.tchek.com (no hyphen). We own both domains and have some sort of domain-wide redirect set up now. This works fine for traffic, but I suspect it's not optimal for SEO purposes. I came to this conclusion by looking in OSE and noticing that none of the inbound links to www.t-chek.com were also being attributed to www.tchek.com. 2 questions: Is it immediately evident what type of redirect I have in place now, or do I need to figure that out? Is the fix as simple as editing the .htaccess file on the hyphenated domain? I don't have direct control over the hyphenated domain, and I'd like to be able to know exactly what we need to do so I can request help from my IT department. I'd appreciate hearing your wisdom. Thanks!
