          This is an Auto-Response for the (very) common question regarding Indexation Times.
          This is an attempt to compile information for questions/issues such as;

          Q: How long does it take to get Indexed.
          Q: How long does Google take to Index a site.
          Q: How fast does Google Index a site.
          Q: Still not Indexed.
          Q: How long does it take to get Crawled.
          Q: How long does Google take to Crawl a site.
          Q: How fast does Google Crawl a site.
          Q: Still not Crawled
          .

          =============   How long to get indexed   =================

          There is No set time in for Google to initially index your site - the time taken can vary.
          The time it does take may vary based upon factors such as;

             * Popularity of the site (Whether it has any links to it)

             * Whether the content is Crawl-able (Server Responses and Content type)

             * Site structure (how pages interlink)

          It is possible for a site to be crawled/indexed within 4 days to 4 weeks.
          In some cases, it may take longer.



          ## Things to do to check/ensure that things are "optimal" for crawling/indexing ##

             * Check Server responses
               Pages should return 200/OK responses.
               Use tools like   http://oyoy.eu/page/headers/  to check the response.

             * Have actual "content"
               This means having content that bots/spiders can "see" and understand (text!).
               If you are using purely Images, solely Flash or loading content up via JavaScript - then you are likely to encounter problems.
               Remember - bots like to "read" - so ensure that you have "text" for them to read!

             * Use "normal" links
               Normal  links are things such as    <a href="some_URL" title="optional"> Some Link Text </a>
               Using JavaScript based events (no href value, instead using on.click or using select list elements with on.click functions etc.) may result in the bots not following!

             * Submit the site
               NO - Verification is NOT the same as Submitting.
               To submit your site - use the URL Submittal tool   http://www.google.com/addurl/?continue=/addurl

             * Be discovered
               If at all possible, have a few links to the site from other sites.
               These links should be from related/topical/relevant sites.
               These links should be from quality/trusted/popular/
          reliable sites.
               Links do seem to help - but do NOT go overboard - it only needs 1 link that is "normal" (can be seen/followed by bots).

             * Verify your site
               Sign up for a Google Webmaster Tools account.
               This does NOT mean the same as Submitting your URL!
               This MAY NOT improve the chances of getting crawled/indexed.
               This can help in discovering/locating/understanding problems as/when/if they occur.

             * Provide a Sitemap
               This is completely Optional!
               Sitemaps do NOT guarantee getting Crawled/Indexed.
               Sitemaps MAY NOT increase your chances of getting crawled/indexed, nor improve the speed/rate.



          ## Common Problems/Causes for initial Crawling/Indexing ##

             * Poor Server responses...
                 - The server sending Bad Responses (404/410/500 etc.),
                 - The server being Slow/Timing out (taking ages to acknowledge/reply to the server request),
                 -  Having Excessive Redirect Strings (Redirect from URL A to B, to C, to D etc.),
                 -  Using non-standard Redirects (JavaScript etc.),
               ...may result in the initial crawl getting stuffed.
            
             * DomainNameServer responses...
               ...that fail to resolve or that have major issues can cause problems.

             * Really shoddy code/markup...
               ...such as seriously malformed <head></head> sections etc. can cause problems.

             * robots.txt ...
                 - being malformed,
                 - being incorrectly setup,
                 - not returning a proper response code,
               ...can cause crawling issues
            
             * robots meta ...
               ...people may have unwittingly blocked bots, included multiple/additional robots tags and unknowingly be denying bots to ability index/follow pages.



          ## Additional ##

          Please, before deciding that your site is Not Indexed ...

          1) Be aware that information/data in the Google WebMaster Tools (GWT/GWMT) may not be "accurate".
              (It is known to be out of date / out of synch in many cases)

          2) To check for your site in the Search Engine Results,
              a) please use the Site: operator  =  in Google search, in teh search box, type in    site:www.yourdomain.tld   or   site:yourdomain.tld)
              b) try doing a search for the <title> of a given page using quotes around it (  "your pages title"  )
              c) try doing a search for a snippet of "unique" content using quotes (  "just copy and paste a short sentence of so from one of your pages"  )

          3) If requesting help/assistance/information regarding your site and getting crawled/indexed - PLEASE supply relevant information.
              Tell us when the site went live, whether you have actually Submitted the site, whether it is Verified, whether you supplied a Sitemap, whether you access to your Server Logs, whether you can see the GoogleBot crawling your site and what response code it gives etc. etc. etc.
