What are the impact of doing URL Rewriting instead of 301 redirections whille optimizing a blog?
-
In WordPress, with the ALL In ONE SEO pluggingm we've optimze the permalinks to show more keewords in the URL'. What can be the impact?

Hi Alexandre,
You will need to look at the code in the .htaccess file generated by All in One SEO to see whether the plugin is just using URL rewriting or creating 301 redirects. As far as I am aware, that particular plugin does not have an option to manually stipulate when you wish to create a 301, but the only sure way is to check the code.
You will need to go into your wordpress /blog directory and download the .htaccess file, then open it in a text editor (like notepad). This is a separate .htaccess file, specifically relating to what happens within your wordpress installation.The one in the root folder for your site will not tell you what you are wanting to know.
I don't use All In One SEO as I prefer the Yoast plugin, but typically, what you might expect to see is code that looks something like this:
BEGIN WordPress
<ifmodule mod_rewrite.c="">RewriteEngine On
RewriteBase /blog/
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]</ifmodule>END WordPress
The key to identifying whether the plugin is using standard URL rewrites or creating a 301 Redirect is to look at the very last part of the Rule - the part that is enclosed in square brackets [ ]
A plain vanilla flavored standard URL Rewrite Rule will end with [L]
If the Rule is creating a 301 (Permanent) Redirect, it will end with [R=301,L]
and for a 302 (Temporary) Redirect, it will end with [R=302,L]
As far as your question, which I understand to be asking essentially, "what is the difference" between the two:
-
A standard URL Rewrite is simply instructing the server that any request for a certain URL should be served a different URL. As far as the search engine is concerned, nothing changes. It is simply used to change the ugly URL to a pretty URL (in your case one that contains the keywords you want).
-
A 301 redirect serves the alternative URL, but also sends a signal to the search engine that the URL requested has been permanently replaced with the one that is served. This indicates to the search engine that the requested URL should be removed from the index and replaced with the URL that is served. A 301 redirect also signals to the search engine that most of the link value being passed to the requested URL should now be passed to the URL that replaces it in the index.
Hope that helps,
Sha

I'm not 100% familiar with all that ALL IN ONE SEO PACK is doing there, but usually when you use mod_rewrite (most commonly that I've seen amongst SEO's to rewrite to 'www'), it IS a 301 redirect.

301 redirecting a previously abused URL
A client previously had their most important landing page at domain.com/example.htm They carried out the sort of link building that was commonplace a few years back (exact match anchors, paid blog links etc) targeting this URL, but they also got a bunch of legitimate decent quality links here. I believe they may have had a number of issues when link quality algo updates were rolled out, so rather than try and get links removed and go through the disavow process they instead decided to abandon this URL, let it 404 and start afresh at domain.com/example.html - updating all internal navigation, XML sitemaps etc. So fast forward to today. What is the best practice for this URL these days do we think? Is it now possible to 301 domain.com/example.htm > domain.com/example.html and recover whatever value may be left here? The argument for not doing so may be that you could pass over the negative metrics associated with the old URL, but would this not be handled by the real-time penguin update and the poor links just devalued rather than actually harming? And could this just be tested - i.e. add in the 301, monitor the impact and if things don't go the way we'd want then just remove the 301 again? Would be keen to get a few opinions on this. TIA

Best way to redirect friendly URL in direct mail ?
Hi, When we do direct mail to our customers talking about a specific product we sell we usually put a link in the letter so the customer can go directly to the product just by typing a short link, something like:
Technical SEO | | BigJoe
www.example.com/blue-widget This link will then re-direct to:
www.example.com/shop/product/brand-name-big-blue-widget-with-green-ends-200m-50diameter.php Which we are happy with at the moment but I want to check we are doing it correctly in terms of redirects, we currently re-direct it using .htaccess like:
Redirect /blue-widget http://www.example.com/shop/product/brand-name-big-blue-widget-with-green-ends-200m-50diameter.php This re-directs it as a 302 but should it be done as a 301 ? I am not sure why we did 302's to start with but I am thinking they should be 301's, I think it might have been because the URL we were redirecting from was imaginary ? Also should we use the Redirect line in the .htaccess or should we do each one with a RewriteRule ? Thanks BigJoe0 -
Changing a blog url from subdomain to subfolder
I am abou to change my company blog from a subdomain (blog.mydomain.com) to a subfolder (mydomain.com/blog), from suggestions from this awesome community! Not only that though, because the current blog is on another server than the main site I have to move my blog between servers as well. This will be a big hassle for me, and means a big risk for errors as I don't have a clue what I am doing on the development part. Hint: I'm no developer. My blog is fairly new, having posted 18 blog posts so far. There is no major linking to or from the blog as it has been basically no activity on the blog. It has been fairly good optimized for SEO, with custom plugin settings for Wordpress SEO plugin and similar. Also followed advice from Rand regarding wordpress SEO. So I guess my question is: Would it be a big loss for me to just start over with a new blog on the subfolder domain? And move content over from the old blog manually (and then deleting the old one). Or would It be plain stupid taking that route? Thankfull for all help I can get!

How long should I keep 301 redirects?
I have modified a the URL structure of a whole section of a website and used mod_rewrite 301 redirect to match the new structure. Now that was around 3 months ago and I was wondering how long should I keep this redirect for? As it is a new website I am quite sure that there are no links around with the old URL structure but still I can see the google bot trying from time to time to access the old URL structure. Shouldn't the google bot learn from this 301 redirect and not go anymore for the old URL?

Google Webmaster redirect vs 301 redirect
OK assuming a client's website has the right tracking script (hopefully analytics isn't effected by this issue), ... what happens if the htaccess file has a 301 redirect to the www-address, but within Google Webmaster Tools, the address chosen to crawl by Google is the non-www address? How will Google handle and which address takes precedence in this situation? _Cindy

IP address URLs being indexed, 301 to domain?
I apoligize if this question as been asked before, I couldnt' find in the Q&A though. I noticed Google has been indexing our IP address for some pages (ie: 123.123.123.123/page.html instead of domain.com/page.html). I suspect this is possibly due to a few straggler relative links instead of absolute, or possibly something else I'm not thinking of. My less-evasive solution a few months back was to ensure canonical tags were on all pages, and then replaced any relative links w/ absolutes. This does not seem to be fixing the problem though, as recently as today new pages were scooped up with the IP address. My next thought is to 301 redirect any IP address URL to the domain, but I was afraid that may be too drastic and that the canonical should be sufficient (which it doesn't seem to be). Has anyone dealt with this issue? Do you think the 301 would be a safe move, any other suggestions? thanks.
