How to Point Multiple Domain Names to One Website: And How to Avoid Search Engine Probl... - 0 views

  • The 3 sites, "example.com", "example.net" and "example.org", all point to the exact same page on the site's web host. It is done by hosting all three sites on the same web host, and arranging it so that they all resolve to the same account.
  • That is, there's a simple way to tell the search engines that all 3 domains point to the same site, and to add up all the links together and associate them with that site.
  • Next, you will also need to arrange with your web host to host all your domains so that they point to the same website.
  • ...3 more annotations...
  • After pointing all your domains to your website, you'll have to decide which of those domains is going to be your primary or main domain.
  • The kind of redirection employed above is recognised by search engines as an indication that all your different domains have moved permanently to your primary domain.
  • After setting the above, wait a couple of days for your changes to spread (or in the technical jargon for such things, "propagate") throughout the world, then test your secondary domains in your web browser.

    "A visitor recently asked me whether it was possible to point multiple domain names to one website, more or less the conceptual reverse of what I wrote about in "Can I Create Multiple Websites with One Domain Name?". This article discusses why a person might want to do this, how it can be accomplished, and provides a practical guide on the additional steps you need to take in order to avoid losing potential search engine ranking as a result of doing things this way."

Microdata - Dive Into HTML5 - 0 views

  • a third option developed using lessons learned from microformats and RDFa, and designed to be integrated into HTML5 itself: microdata.
  • “Adding microdata” to your page is a matter of adding a few attributes to the HTML elements you already have.
  • So where is the real information? It’s in the <dd> element, so that’s where we need to put the itemprop attribute. Which property is it? It’s the name property. Where is the property value? It’s the text within the <dd> element. Does that need to be marked up? the HTML5 microdata data model says no, <dd> elements have no special processing, so the property value is just the text within the element.
  • ...7 more annotations...
  • This technique is also useful for microdata. There are two distinct pieces of information here: a title and an affiliation. If you wrap each piece in a dummy <span> element, you can declare that each <span> is a separate microdata property.
  • There are two major classes of applications that consume HTML, and by extension, HTML5 microdata: Web browsers Search engines
  • a handy tool to see how Google “sees” your microdata properties
  • Google supports microdata as part of their Rich Snippets program.
  • Just like associating a URL with a Person, you can associate a URL with an Organization. This could be the company’s home page, a contact page, product page, or anything else. If it’s a URL about, from, or belonging to the Organization, mark it up with an itemprop="url" attribute.
  • To handle edge cases like this, HTML5 provides a way to annotate invisible data. This technique should only be used as a last resort. If there is a way to display or render the data you care about, you should do so. Invisible data that only machines can read tends to “go stale” quickly. That is, someone will come along later and update the visible text but forget to update the invisible data. This happens more often than you think, and it will happen to you too.
  • itemscope says that this element is the enclosing element for a microdata item with its own vocabulary (given in the itemtype attribute). All the properties within this element are properties of http://data-vocabulary.org/Geo, not the surrounding http://data-vocabulary.org/Organization.

sitemaps.org - Protocol - 0 views

  • You can specify the location of the Sitemap using a robots.txt file. To do this, simply add the following line including the full URL to the sitemap: Sitemap: http://www.example.com/sitemap.xml This directive is independent of the user-agent line, so it doesn't matter where you place it in your file. If you have a Sitemap index file, you can include the location of just that file. You don't need to list each individual Sitemap listed in the index file.
