Create SEO compliant contents. To build the foundation for a website that is well indexed and easily found by visitors, proceed as follows: Choose appropriate titles for your contents If you change a content title, remember to update the content "Name" accordingly: it is used by SevenDaysWeb as link to the content page. Remember to do the same for category title and name. These are the basic SEO - and thus web marketing - rules. As an example, look at the link to the "Modular" content pege in this website: http://sevendaysweb.com/plus/modular-website.html Queste informazioni sono mappate dai motori di ricerca nelle loro operazioni di indicizzazione e sono la prima linea di informazioni che essi forniscono al pubblico per individuare la pagina. Also important is to write content which is at least interesting - if not compelling - to the audience, select and add relevant keywords to contents, assign relevant names and keywords to content images. Banners e Advertising. Banners can be either third-party ads or internal highlights, leading to interesting articles and news within your website; in both cases they are managed the same way. Social Networks. Social network integration requires setting your Twitter, Facebook, Google+ and LinkedIn accounts in the Website Information page; it is supported by SevenDaysWeb depending on the layout you have chosen. Landing Pages and Advertising Campaigns. If you advertise your website with Google, make sure that the keywords you use in your Google campaign are consistent with those entered in your website contents. SevenDaysWeb allows you to create campaign specific landing pages, to guide the website visitors through a path that may be targeted to selling, lead conversion, or just providing useful information. The same principle can be applied to newsletter based campaigns. SevenDaysWeb is a professional tool, that allows you to define and manage all aspects of online communication, even the most critical.
FreeMarker template error (HTML_DEBUG mode; use RETHROW in production!)
The following has evaluated to null or missing:
==> sharethis_active [in template "settegiorniweb.it/layouts/macro/_google_analytics.ftl" at line 38, column 8]
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
