Re: GWT - Crawlable (SEO)
I can only comment how I did it; Googles bot will read any url in the form: #!key1=value1key2=value2 As: ?_escaped_fragment_=key1=value1%26key2=value2 Thus I built a php version of my site that delivered the same content without the need for JavaScript. By using escape fragments the same request data is avaliable to the server as the client, so you should be able to pull up the same contents as the client. (for example, from a mysql database). So effectively the javascript and php versions of my site mirror eachother in terms of content, and the bot has access to the php one via the ?_escaped_fragment_ url standard.

Re: GWT Crawlable (SEO)
Jan you seem to be kind of trolling; duplicate thread created 5 days ago by yourself and you clearly didnt bother to use the search feature but I will answer anyways Just copy the filter I wrote: https://groups.google.com/forum/#!topic/google-web-toolkit/aBt-QCCQkKY On Thursday, December 27, 2012 3:36:17 AM UTC-8, Jan wrote: Hi I like to make my GWT-App by the google bot.

If i use for example the activities and places pattern, than the page changes are on the client-side only and there is no servlet involved - servlet filter does not work here. Can someone give me an explanation? Or is there another good tutorial tailored to gwt how to do this?

Re: GWT Crawlable (SEO)
Check out this link, specifically point 3 on how to set up a servlet filter that works with _escaped_fragment. https://developers.google.com/webmasters/ajax-crawling/docs/html-snapshot You now have two choices: in the link above, they use a java WebClient ( http://htmlunit.sourceforge.net/ ) to grab the html from your real page. The WebClient can parse javascript, and if your GWT page is fairly straight forward it should just work and give the right html back to google bot with zero extra work beyond the web.xml config / filter on your end. However, if WebClient can't get good data from your pages (you'll need to test using WebClient directly), then you can inline some html for any pages that don't work, and you can make calls to your database/servlets to pull any dynamic data you might need. This output should be valid html, but it doesnt have to be pretty - just a bodyLots of text here.../body is enough for googlebot to understand the content on your page.

Re: GWT Crawlable (SEO)
I solved this by effectively having a crudely laidout, but text/ content identical php system that gives the content when javascript isnt present and a ?_escaped_fragment_ url is given. As a bonus to making my site crawlable, this also makes it usable(ish) for those without javascript on.
