    - by Josemalive

I supposed that not only will be sufficient the following tasks: Improve usability of those pages. Change the pages title. Add meta description and keywords. Url's in a REST way. 301's http header to dont lose page rank for the new URLS Optimizing content for Google. Configure links of the website (follow and no follow attributes) Get more inbounds links (Link building tasks). Create RSS. Put main website in Twitter (using twitter feed) using the RSS. Put main website in Facebook. Create a Youtube channel. Invest in Adwords. Invest in other online advertising companies. Use sitemap.xml and Google Webmaster tools. Use Google Trends to analyze the volume of searches of certain keywords. Use Google Analytics to analyze weak points and good points of your site, and find new oportunities in keywords. Use tools to find new keywords related with your content. Do you have some internet links, or knowledge about all the tasks that a SEO Expert should do? Could you share some knowledge about what kind of business could be do with another companies (B2B) to increase the search engine position of those product pages. Do you know more tecniques about how to get more inbound links? (i only know the link interchange) Thanks in advance. Best Regards. Jose.

  • What's the best C# recommendation engine or framework?

    - by cDima
    Is there anyway to use the examples for the "My Media" Microsoft research project? My Media is a "dynamic personalization and recommendation software framework toolkit" ( http://www.mymediaproject.org ), but out of the box it doesn't provide a sample database (only a LINQ-to-SQL .dbml schema), I don't believe it will be easy to re-create by hand. I was hoping to understand recommendation engines and machine learning with this C#/.Net as a testbed, but without a simple quick start or db it seems impractical. Any suggestions? (I guess it's time to switch to Java with Apache's Mahout, Weka or something similar?)

  • using grails and google app engine to store image as blob and the view dynamically

    - by mswallace
    I am trying to dynamically display an image that I am storing in the google datastore as a Blob. I am not getting any errors but I am getting a broken image on the page that I view. Any help would be awesome! I have the following code in my grails app domain class has the following @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Long id @Persistent String siteName @Persistent String url @Persistent Blob img @Persistent String yourName @Persistent String yourURL @Persistent Date date static constraints = { id( visible:false) } My save method in the controller has this def save = { params.img = new Blob(params.imgfile.getBytes()) def siteInfoInstance = new SiteInfo(params) if(!siteInfoInstance.hasErrors() ) { try{ persistenceManager.makePersistent(siteInfoInstance) } finally{ flash.message = "SiteInfo ${siteInfoInstance.id} created" redirect(action:show,id:siteInfoInstance.id) } } render(view:'create',model:[siteInfoInstance:siteInfoInstance]) } My view has the following <img src="${createLink(controller:'siteInfoController', action:'showImage', id:fieldValue(bean:siteInfoInstance, field:'id'))}"></img> and the method in my controller that it is calling to display a link to the image looks like this def showImage = { def site = SiteInfo.get(params.id)// get the record response.outputStream << site.img // write the image to the outputstream response.outputStream.flush() }

  • Google App Engine + AdWords API: java.lang.NoClassDefFoundError: javax/xml/soap/SOAPException

    - by Konrad
    Hi all, I know a lot so far about this exception. But I am wondering, if any of you tried to use AdWords API on GAE. AdWords uses Axis as underlying WS library, which do not work on GAE and unfortunately I cannot find solution to make it working. I tried already this: http://dev.bizo.com/2009/04/calling-soap-web-services-on-google-app.html Does any of you know if there is a way to use AdWords API on GAE with Java? Thanks in advance for any help Konrad

    How can I comment out parts of a Spark view so they aren't rendered to the client? In aspx pages I can do this: <%-- server-side comment --%> I had thought using three dashes would work: <!--- server-side comment ---> but it doesn't work and I now can't find the resource where I read that.

    This is using the web app framework, not Django. The following template code is giving me an TemplateSyntaxError: 'for' statements with five words should end in 'reversed' error when I try to render a dictionary. I don't understand what's causing this error. Could somebody shed some light on it for me? {% for code, name in charts.items %} <option value="{{code}}">{{name}}</option> {% endfor %} I'm rendering it using the following: class GenerateChart(basewebview): def get(self): values = {"datepicker":True} values["charts"] = {"p3": "3D Pie Chart", "p": "Segmented Pied Chart"} self.render_page("generatechart.html", values) class basewebview(webapp.RequestHandler): ''' Base class for all webapp.RequestHandler type classes ''' def render_page(self, filename, template_values=dict()): filename = "%s/%s" % (_template_dir, filename) path = os.path.join(os.path.dirname(__file__), filename) self.response.out.write(template.render(path, template_values))

  • Problem with Google App Engine Appstats

    - by Taylor L
    I'm having an issue getting Appstats to work correctly. Using /appstats or /appstats/stats ends up in an infinite loop that keeps redirecting back to /appstats/stats. This results in a 404 error saying the page isn't redirecting properly. Any idea what the issue is? Here are the relevant lines in my appengine-web.xml. I've tried using both /appstats/stats and /appstats and they both have the same issue. <admin-console> <page name="Appstats" url="/appstats/stats" /> </admin-console> Below are the http headers showing the infinite redirect loop: http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcHiwT8jH7e01V9O5iFu3kpBhDd3k3oBwwxylv5u0DbJ- utvdpsgdb4Xim2WXwobkJmgTGGljvuh94_yVQ__- VPnBsTtUAhRjSyZ2Lv3G7oUHAxTsCWHJIMChGT3- XUyUNx8wxwvJisL_RTXH8Hc4TTLh_rVHm2k8gk8kgdbVZXexSV0K- a3coELTecWIBolt0qLd5L-5vALm382KsqbHorPXqoZMPTvR_06g_mR1cbmF2Ihnk6YhP7no58BNpESM9HvFyKNKXODo39hF4oaZCcW0Q9TBqUMgsrBqlcIh3- VvC7qvH0n_nAtrLTBbK_swnOFvCDcaf3whT9ty0CJ0VRNuNqIPOLHIeQAMgwXUNMr89P64EsgmuyONHR67glCQXEPOGXIaT1vcBJFwFoeNUqjdp824fHvoVhaL7Xlav- LTIFuM3f_ymHLmibk57PRuXUYEaAG HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.645553 X-AppEngine-Resource-Usage: ms=18965 cpu_ms=27884 api_cpu_ms=0 Set-Cookie: ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS; expires=Mon, 12-Apr-2010 19:41:49 GMT; path=/ Date: Sun, 11 Apr 2010 19:42:08 GMT Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Cache-Control: no-cache, must-revalidate Content-Type: text/html Server: Google Frontend Content-Length: 0 ---------------------------------------------------------- http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.002243 X-AppEngine-Resource-Usage: ms=64 cpu_ms=93 api_cpu_ms=0 Date: Sun, 11 Apr 2010 19:42:08 GMT Content-Type: text/html Server: Google Frontend Content-Length: 0

  • App engine datastore - query on Enum fields.

    - by Gopi
    I am using GAE(Java) with JDO for persistence. I have an entity with a Enum field which is marked as @Persistent and gets saved correctly into the datastore (As observed from the Datastore viewer in Development Console). But when I query these entities putting a filter based on the Enum value, it is always returning me all the entities whatever value I specify for the enum field. I know GAE java supports enums being persisted just like basic datatypes. But does it also allow retrieving/querying based on them? Google search could not point me to any such example code. Details: I have printed the Query just before being executed. So in two cases the query looks like - SELECT FROM com.xxx.yyy.User WHERE role == super ORDER BY key desc RANGE 0,50 SELECT FROM com.xxx.yyy.User WHERE role == admin ORDER BY key desc RANGE 0,50 Both above queries return me all the User entities from datastore in spite of datastore viewer showing some Users are of type 'admin' and some are of type 'super'.

  • Java App Engine - ranked counter

    - by Richard
    I understand the sharded counter, here: http://code.google.com/appengine/articles/sharding_counters.html The problem is that a simple counter will not work in my application. I am sorting my entities by a particular variable so I am returned not so much a count, but more of a rank. My current method is: SELECT COUNT(this) FROM Entity.class WHERE value <= ? Result + 1 is then the rank of the parameter in relation to the value variable in the persistent Entity objects. The limitation of this is the highest rank being returned is 1001 because count() can give a maximum of 1000. The reason I cannot store the rank on the Entity object is that the ranks are updated very often, and re-setting this rank variable would be much too costly. Any ideas on the best way to accomplish this?

  • Using sub filters/queries in Google App Engine

    - by fredrik
    Hi, I'm trying to use figure out how to sub query a query that uses a filter. From what I've figured out so far while using .filter() it changes the original query, that leads to a second .filter() would also have to match the first filter. I would like to make something like this: modules = data.Modules.all().filter('page = ', page.key()) modules.filter('name = ', 'Test') modules.filter('name = ', 'Test2') I can't get the "Test2" filter to work. The only solution I have at the moment is to make all new queries. data.Modules.all().filter('page = ', page.key()).filter('name = ', "Test").get() data.Modules.all().filter('page = ', page.key()).filter('name = ', "Test2").get() Or write the same as an GQL. But for me it seams quite stupid way to go. I've looked at using ancestors, but I don't quite understand it and honestly don't know if that's the way to go. Any ideas? ..fredrik

  • database design in google app engine

    - by iamgopal
    hi , i am designing a simple project based to do list. the idea is to define tasks under project ( no workflow - just "task is completed" or not is required. ) in a hirarchial way. i.e. each task has multiple task and that task may have other multiple task. a project can be said to be completed if all task under that project are completed. , i tought of using refrenceproeperty to create hirarchy , but could not figure out easy way ( which do not take more than 30 seconds to find all the children of a project and check weather it is completed or not ) . to detect if project is complete or not. how to design database for such job ? and also , if i need to copy the project in order to define another project , how to copy hierarchical data ?

  • Google App Engine - Blob Store Service with a Dispatcher Servlet

    - by Rahul
    I have a central dispatcher servlet that has a servlet mapping of : <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> When i try to use the blob store service's createUploadUrl("/uploadComplete") it maps to a URL for e.g *'/_ah/upload/agp0d2VldG15cGljchsLEhVfX0Jsb2JVcGxvYWRTZXNzaW9uX18YEgw'*. Before the Blob store service can handle the upload and redirect to /uploadComplete; my dispatcher servlet gets called and i am therefore not being able to upload anything. Is there a servlet/ filter that i can map to /_ah/upload/* in my web.xml ? How do i avoid the dispatcher servlet from getting called before the Blob store service can do its thing?
