    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.
