I'm trying to clear up a grey area about this much talked about topic...
Like most devs, I've made some pretty URLs with mod_rewrite. My sites internal links point to the pretty URLs and things are working nicely.
But, I can still access the old URL if I point to it directly.
Now, this is most certainly going to cause duplicate content issues so after doing some research it seems that 301 redirects are the way to go.
But.... and here's the grey bit...
If you are working on a site with thousands of URLs, what's best practice to achieve this? I don't wantto list 1k+ lines in .htaccess I thought of a regexp in my rewrite rule, but my pretty URLs have names from the database in them... and I can't access that from .htaccess :)
Have I hit a dead end? Is there a way around this? Would Google's canonical tag be a possibility??
Well, I don't know if this is the "definitive" answer, but I have a bunch of "functional" URLS like:
http://www.flipscript.com/product.aspx?cid=7&pid=42&ds=asdjlf8i7sdfkhsjfd978
but I remap the URLs, link to them and list them in my site map as:
http://www.flipscript.com/ambigram-ring.aspx
I haven't seen ANY evidence that identical URLS pointing to the same content within the same domain has any negative impact on SEO.
In fact, over the past year, I have climbed to the #1 position on Google with this in place for my primary keyword.
My theory about why this should be so is that Google applies the duplicate content penalty for entire "clone sites", not for just linking with different URLs to the same content within a single site.
A quick dirty way would be to re-route everything on the site via a PHP file that checks to see if the path is still valid, querying the database if necessary. Use a 301 redirect if the path has permanently moved. Soon enough these "grey urls" should hardly ever come across, and indexes should be updated across search engines. At which point you can remove the router.
If you could specify what your "grey url" looks like I may be able to suggest a better alternative.
"Would Google's canonical tag be a possibility??" -- Why not?
--> It automatically transfers page rank
--> Google recommends canonical tag even if the content differs slightly but is more or less similar.
--> Too many 301 redirects to pages within site are bad for SEO (my personal experience with Bing).
--> Too may 301 redirects increase the effective load time of content for your users (especially bad if the ping times from their location to your server is high).

Is there a problem if I have both English and Chinese versions of the same title/meta tags under the same exact url? I detect the language the user has set for the browser (through the http header "accept-language" field) and change the titles/meta tags based on the language set. I get a large percentage of my traffic from China and felt this was a better-localized user experience for those users BUT I have no idea how Google would view this. My gut feeling tells me that this is not good for SEO.
Baidu.com, a major Chinese search engine, does in fact pick up my translated tags however for other US based sites it does not translate their English title/meta tags into Chinese. I would think Chinese users are less likely to click on those.
Creating sub domains and or separate domains for other countries is not an option at this point. That being said should I only have one language (English) for my title/meta tags to avoid any search engine issues?
Thanks for any advice / wisdom you can offer. Really hoping to get clarity on best practices.
Thanks all!
Yes, it probably is a problem. Search engines see mixed language content. You are not describing how you “detect and change the titles/meta tags based on the users browser language”, but you are probably doing it client-side and using “browser language”, which is wrong whatever it means in detail (it does not specify the user’s preferred language).
To get a more targeted answer, ask a more real question, with a URL.
If you want to get search traffic from search engines in both English and Chinese, you should have two urls instead of one.
When googlebot crawls a page, it does not even send the "Accept-Language" header. You have to send it your default language. When there is one url, there is no way for you to have your second language indexed. You won't be ranked in search engines in multiple languages.
For best SEO, use separate top level domains, subdomains, or folders for different languages.
http://example.de/
http://example.es/
http://example.com/
http://de.example.com/
http://es.example.com/
http://www.example.com/
http://example.com/de/
http://example.com/es/
http://example.com/en/
I think there are no problem when you use English and Chinese in same meta tags.
Hi i hve been running forum for quite while and people started using it for spam etc and now even though i took it down i still got like 100 clicks day for threads that dont exist and the forum is not existing too.
I tired of seeing this crap in my piwik stats i want to move it with mod rewrite so every time someone access
site.com/samples/forum he goes soemwhere else like actual redirect to fbi.com etc. better without showing my url of couse or just to some non existing folder so it does not triger my stats.
You're probably looking for something along the lines of:
RewriteEngine on
RewriteRule /samples/forum http://othersite.com/path [L,R]
(of course can flex if you need patterns, or for different paths) There are tons of handy options that you can use, all documented in Apache's documentation.
I'd like to strip a URL of it's query string using mod_rewrite but retain the values of the querystring, for example, id like to change:
http://new.app/index.php?lorem=1&ipsum=2
to a nice clean:
http://new.app/
but retain the values of lorem and ipsum, so inside index.php:
$_GET["lorem"]
would still return 1 etc.
This is my first dabble with mod_rewrite so any help is greatly appreciated, and if you could explain exactly how your solution works, I can learn a little for next time too!
Thanks!
As Roland mentioned, you don't seem to understand the way rewriting works. It's typically done using Apache mod_rewrite in .htaccess, which silently rewrites the pretty URLs to the php script as /index.php?lorem=1&ipsum=2
Even Joomla uses .htaccess, except it has a single rewrite rule that passes EVERYTHING to a PHP script which does the actual rewriting in PHP.
What you are not understanding is that something still needs to exist in the "pretty" version for the php script to pull the value of $_GET["lorem"]
So it would be like http://new.app/lorem/ or http://new.app/section/lorem which would then (using mod_rewrite in .htaccess) rewrite TO the php script.
I don't understand exactly what you want. Your first URL is the external form, which the users see and can type into their browsers.
The second form has almost all information stripped, so when you send that to a server, how is the server supposed to know that lorem=1&ipsum=2?
If your question is really
How do I make the URLs in the browser look nice, even if the user is somewhere deep in the website clicking on URLs that carry lots of information?
then there are two solutions:
You can pass the information in small bits to the server and save them all in a session. I don't like that because then the user cannot take the URL, show it to a friend and have him see the same page.
You can have your entire web site in an HTML <frameset> containing only one <frame>. That way, the URL of the top-level window will not change, only the inner URL (which is not displayed by the browser) will.
Having a look at how google perceives our site at the moment and coming up short...
Basically, we use a bog-standard structure of URL rewriting to make them look SEO friendly.
for instance, a product URL takes shape of any string_([0-9]).html and so forth. of course, this allows us to link to whatever we want before the product id... which we have done. In the past, a product page was Product_Name_79.html and then became Brand_Name_Product_Name_79.html. apache does not really care and id 79 gets passed on in either case. However, google now has 2 versions of this product cached under different URLs - and that's not a good thing as it continues to arrive to the first URL and spider it.
same thing applies to our rewrite rules for brands and categories, some of which had been dropped and some of which have been modified.
there are over 11k urls in site:domain whereas our sitemap gets some 5.8k only. how would you prevent spiders from fetching older versions of urls that you no-longer link to (considering it's not a manual process and often such urls can be very dynamic).
eg, Mens_Merrell_Trail_Running_Shoes__50-100__10____024/ is a dynamic url for the merrell brand, narrowed down by items in trail running shoes that cost between 50 and 100 and size 10 with gender set to men's.
if we decide to nofollow any size and money filter urls, that leaves google still being able to access them through its old cache...
what is the best practice for disallowing a particular type of urls? as the combinations above are nearly infinite, i cannot produce a list and it certainly cannot be backdated against what brands and categories google may hold for us historically.
shall we add noindex when such filters are applied? shall we export them to robots.txt? do nothing in the hope that google stops returning?
to put it into perspective, we have 2600 product page urls that are now redundant / disabled, what would you do with them? redirect to homepage, brand page, 404, do nothing?
thanks for any advice
i think you're looking for rel="canonical", google should start ignoring you're links if they're really not linked to. You can check any incoming links with a tool like this: http://www.seomoz.org/linkscape.
Also if you're old urls match (or don't match) a consisent pattern you could set up a 301 redirect in apache either for pages matching the old pattern or not matching the new pattern...
hope this helps!
Just be sure to set up redirects for any URL you change. Also, I don't recommend using rel=nofollow since it indicates to Google that your site is not trustworthy.
What do you think.. are clean URLs a backend or frontend 'discipline'
The answer is BOTH.
For example:
https://stackoverflow.com/questions/203278/are-clean-urls-a-backend-or-a-frontend-thing
The number above is a database id, a back-end thing. Chop off the pretty part and it goes to the same page. Therefore the "are-clean-urls-a-backend-or-a-frontend-thing" is part of the front-end thing.
If we're talking url's being 'clean' from an end user experience then I'm going to break the mould a bit and say that url's in general are not intuitive and they never will be, they are intended to be machine readable.
There is no standard to the format of a url such that when navigating from site to site humans will never ever remember how to reach a resource purely through remembering urls and their 'friendly syntax'. We can argue the toss about whether using a '?' and '&' or '/' to express how how to identify a resource via a url; is one method better than the other? it doesn't matter. At the end of the day a machine parses it and sends back the result.
We should stop deluding ourselves that people actually type these things in and realise that uri's are for machines, not people.
I have yet to use/remember a uri that goes beyond the first few characters of the http://domain.com/ part of an address, and I've been using the web since a long time. That's what bookmarks are for. Nowhere on a website does it say 'change this part here in our url to view 'whatever else' resource' because url's are usually undocumented and opaque.
Yes make your uri's SEO friendly (hell even they change periodically) but forget about the whole 'human/clean' resource identifier thing, it's a mystical pipe dream.
I agree with Vlion that url's should provide a unique mechanism to bookmark a resource and return to it (unlike some of these abominable web 2.0 ajax/silverlight/flash creations), but the bookmark will never be for humans to comprehend and understand. There seems to be quite a lot of preoccupation and energy spent in dreaming up url strategies that humans can remember and type in, it's a waste of energy. Let's get on and solve real problems.
Sorry for the rant, but there's a lot of web 2.0 nonsense related to urls going on in certain circles that are just a total waste of time.
Now that Firefox's Awesome bar and Google Chrome's Omnibox address bars can be used to search the browsing history it makes it much easier for users to search their history for previously visited sites, so having clean urls may help the user find sites in their history more easily.
Making sure the page has an appropriate Title is important (as both browsers search the title as well as the url) but by making sure the url has relevant keywords in it as well, when those keywords are typed in the address bar the urls will be more likely to show up higher in the suggestions as the keyword will be matched twice, in the url and the title.
Also, once a user has typed the name of a site they will be presented with example urls from the site which they can then use as a template for narrowing down their search. So using verbs and nouns in the url for different sections or actions of the site will aid the user to narrow their search to just the part of the site they are interested in, e.g. the /questions/ or /tag/ sections of stackoverflow, or the "/doc" at the end of docs.google.com/doc that can be used to view just document pages on Google docs*.
Since both Firefox and Chrome search for each space separated word typed into the address bar, it could be argued that it isn't necessary for searching that the url be completely human readable, but to allow the user to actually read the keywords they are interested in from the url the amount of "noise" should be kept to a minimum.
* which are of the form http://docs.google.com/Doc?id=gibberish
My perspective is simple:
every place I visit with my browser(with various edge case exceptions) should be bookmarkable and Forward/Back should be usable and not destroy any data entry.
Backend for sure. Your server is the one that has to take care of the routing to the resources requested by the URL.
I think the main reasons for using friendly URLs are:
Ease of linking / sharing
Presentation
Seo
So I think it's purely a client-side pleasure. While they're nice on the server as well, they're not mission critical.
