I want a program that does that, from a website, get all the urls indexed to it with a good output, like, all the urls line by line, and get the urls not used in the website (because a spider can already do that).
I have been searching and finding sloopy options, what I want is accurate and simple: INPUT: URL OUTPUT: ALL THE URLS.
I don't know such applications for now, but I'll try to simplify your task by dividing it:
Yon need a list of your website's internal links. Any webcrawler tool can do that.
You need a list of your website's pages indexed by Google. There are a lot of SE index checkers, you can google it.
Compare 2nd list to the 1st one, and find all the links presents in Google's index but missing on your website.

On the webmaster's Q and A site, I asked the following:
https://webmasters.stackexchange.com/questions/42730/how-does-indeed-com-make-it-to-the-top-of-every-single-search-for-every-single-c
But, I would like a little more information about this from a development perspective.
If you search Google for anything job related, for example, Gastonia Jobs (City + jobs), then, in addition to their search results dominating the first page of Google, you get a URL structure back that looks like this:
indeed.com/l-Gastonia,-NC-jobs.html
I am assumming that the L stands for location in the URL structure. If you do a search for an industry related job, or a job with a specific company name, you will get back something like the following (Microsoft jobs):
indeed.com/q-Microsoft-jobs.html
With just over 40,000 cities in the USA I thought, ok, maybe it's possible they looped through them and created a page for every single one. That would not be hard for a computer. But then obviously the site is dynamic as each of those pages has 10000s of results and paginated by 10. The q above obviously stands for query. The locations I can understand, but they cannot possibly have created a web page for every single query combination, could they?
Ok, it gets a tad weirder. I wanted to see if they had a sitemap, so I typed into Google "indeed.com sitemap.xml" I got the response:
indeed.com/q-Sitemap-xml-jobs.html
.. again, I searched for "indeed.com url structure" and, as I mentioned in the other post on webmasters, I got back:
indeed.com/q-change-url-structure-l-Arkansas.html
Is indeed.com somehow using programming to create a webpage on the fly based on my search input into google? If they are not, how are they able to have a static page for millions and millions and millions possible query combinations, have them dynamically paginate, and then have all of those dominate google's first page of results (albeit that very last question may be best for the webmasters QA)?
Does the javascript in the page somehow interact with the URL
It's most likely not a bunch of pages. The "actual" page might be http://indeed.com/?referrer=google&searchterm=jobs%20in%20washington. The site then cleverly produces a human readable URL using URL rewrite, fetches jobs in the database that matches the query, and voíla...
I could be dead wrong of course. Truth be told, the technical aspect of it can probably be solved in a multitude of ways. Every time a job is added to the site, all pages that need to be done to match that job, might be created, thus producing an enormous amount of pages for Google to crawl.
This is a great question however remains unanswered on the ground that a basic Google search using,
ste:indeed.com
returns over 120MM results and secondly a query such as, "product manager new york" ranks #1 in results. These pages are obviously pre-generated which is confirmed by the fact the page is cached by the search engine (sometimes several days before) has different results from a live query on the site.
Easy when Googles search bot crawls the pages on indeed or any other job search site those page are dynamically created. Here is another site: http://jobuzu.co.uk i run this which is similar to how indeed works.
PHP is your friend in this and Indeed don't just use standard databases look into Sphinx and Solr as they offer Full text search for better performance then MySql etc.
They also make clever use of rel="canonical" and thorough internal linking:
http://www.indeed.com/find-jobs.jsp
Notice that all the pages that actually rank can be found from that direct internal link structure.
I am managing a website that has only about 20-50 pages (articles, links and etc.). Somehow, Google indexed over 1000 links (duplicates, same page with different string in the URL). I found that those links contain ?date= in url. I already blocked by writing Disallow: *date* in robots.txt, made an XML map (which I did not had before) placed it into root folder and imported to Google Webmaster Tools. But the problem still stays: links are (and probably will be) in search results. I would easily remove URLs in GWT, but they can only remove one link at the time, and removing >1000 one by one is not an option.
The question: Is it possible to make dynamic 301 redirects from every page that contains $date= in url to the original one, and how? I am thinking that Google will re-index those pages, redirect to original ones, and delete those numerous pages from search results.
Example:
bad page: www.website.com/article?date=1961-11-1 and n same pages with different "date"
good page: www.website.com/article
automatically redirect all bad pages to good ones.
I have spent whole work day trying to solve this problem, would be nice to get some support. Thank you!
P.S. As far as I think this coding question is the right one to ask in stackoverflow, but if I am wrong (forgive me) redirect me to right place where I can ask this one.
You're looking for the canonical link element, that's the way Google suggests to solve this problem (here's the Webmasters help page about it), and it's used by most if not all search engines. When you place an element like
<link rel='canonical' href='http://www.website.com/article'>
in the header of the page, the URI in the href attribute will be considered the 'canonical' version of the page, the one to be indexed and so on.
For the record: if the duplicate content is not a html page (say, it's a dynamically generated image), and supposing you're using Apache, you can use .htaccess to redirect to the canonical version. Unfortunately the Redirect and RedirectMatch directives don't handle query strings (they're strictly for URIs), but you could use mod_rewrite to strip parts of the query string. See, for example, this answer for a way to do it.
I'm having a hard time finding out where to start with this one. I pull information from an external website and put some of the content on my page. I think I need two things done. 1. A google search that takes the url of the top search given a name of my current object. 2. A way to examine the source of the result and output the information of a tag with a specific class.
To better explain this, I'll create a hypothetical situation: Say I have a website that lists mattresses and gives reviews. Say I want to add other websites reviews and in this website there's a tag like 3.5/5. Then I want to display this review along with a link to the external page. Is there a way to search the site like "site:http://mattressreviewsite/ #matress.name", pull that top url, and then search the source for the string "class='rating'" and display this in my view?
Thanks for any help or guidance. I'm using Rails 3.
You need an HTTP client (httparty, net/http-default) for that and do some parsing to get the required results.
Go study the url patterns of google (as far as I remember it was google.com?q=search_string) and use the http client for requests (get/post). Parse the result (there are many HTML parser gems available too) to get what you need and for any subsequent HTTP requests. And don't forget the 'I am feeling lucky' feature of google which returns only one result.
All the best!
Basically I want to know how many people have tweeted a link to a url, but since there are dozens of link shortener out there I don't see any way to do this without having access to all of their url maps. I found a previous question here but it was over a year old and didn't have any new answers.
So #1, does anyone know of a service/API for doing this?
And #2, can anyone think of a way to accomplish this task other than submitting the long url in question to all the popular link shortening sites?
ps- I'm also open to comments about why this is impossible or impractical.
You could perform a Google search (or the equivalent via API) for any pages that link to your page. This is done with the link: keyword. So if you're trying to figure out how many people link to www.example.com (regardless of whether it's through a link shortner URL), then you would just do a Google search for link:www.example.com.
e.g.: http://www.google.com/search?q=link:www.example.com
Note that this will only find pages that have been indexed, so pages that haven't been crawled, or pages that get crawled infrequently, will not show up in the results until a later date (if at all).
Since all sites have different algorithms for shortening the URLs, and these are different sites that most likely do not share their data with each other, how can you hope to find all of them in a single or small number of queries?
All you can do is brute-force it, and even then this might not be any good if a site is content to create a new value for the same long-form URL (especially if you send a different long-form URL that maps to the same place, like http://www.stackoverflow.com/ rather than http://stackoverflow.com/).
In order to really get this to work, there would have to be a site that ALREADY automatically collects all of this information from every site, which the URL shortening sites voluntarily call. And even if you wrote such a site, that doesn't account for the URL-shortening sites already out there who already have data!
In short, I do not see how this is remotely possible, unless I'm wrong about there being such a database somewhere out there.
So months after asking this question I came across a solution to a similar question, that is how to tell how many times a link has been shared on facebook. The solution, via a simple new API call:
http://graph.facebook.com/http://stackoverflow.com
returns the following json data:
{
"id": "http://stackoverflow.com",
"shares": 1627
}
How can i get private pages of my web site being crawled and indexed by google ?
maybe it's not very "conventionnal", but i want my private page "links" displayed in google index, but next require a registration to display the page.
EDIT: Based on the addition of "maybe it's not very "conventionnal", but i want my private page "links" displayed in google index, but next require a registration to display the page." To the question:
You can check the User Agent in your php code to basically allow google to see pages if it was a registered user (google's user agent is "Googlebot/1.0" and you can search to find user agents for other common engines).
However, this behavior is specifically against google's rules and they can and will remove your site from the index if they catch you doing it. Their policy is you should not treat googlebot any differently than you treat any random person who visits your site.
(Original Answer) One way is to use a sitemap to show google how to find all of your pages.
In general, and even in the case of sitemaps, if the content you want indexed is not linked to from a page that can be found through the "root" (/) (i.e. there is no way for the public to find it), then it probably won't get indexed. The only way to get it indexed is to link it in someplace.
The question is though, why do you want your private pages in google anyway?
They'll get crawled if and only if they're publicly accessible and your robots.txt file allows it. That's pretty much all you need to do.
Are you asking how to get Google to index your pages?
There are a couple of ways. You need to ensure that you have SEO'd, or Search Engine Optimisation, the pages properly with title text and description key words in your meta data.
You can also submit your site to Google, it's a free service, and it'll be placed in a queue of things that Google will index. May take some time though.
By far the best way to get your pages indexed is using the meta data in the pages themselves.
Google will only index what is
linked from somewhere already in Google's index
accessible to its crawler via normal (unauthenticated) HTTP
It will also
make the contents available in search results to anyone.
This may conflict with your idea of a "private" page.
I'm going to assume that all the other previous answerers are misunderstanding you. As I read it, you aren't asking how to get Google to index your pages, but rather how to get a list of all the pages that Google currently has already indexed on your site? If that is true, you should have a look at the Google Webmaster Tools.
