How to use
Simply add the SeoWidget into your UiBinder. It currently supports all the following tags :
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui"
xmlns:seo="urn:import:com.arcbees.seo.widget">
<g:HTMLPanel>
<seo:SeoWidget>
<seo:Title>My Title</seo:Title>
<seo:Description>My Description</seo:Description>
<seo:Keywords>kw1,kw2,kw3</seo:Keywords>
<seo:Og>
<seo:OgImage height="480" width="480">http://some.image.png</seo:OgImage>
<seo:OgType typeValue="WEBSITE"/>
</seo:Og>
<seo:Custom property="og:audio">http://example.com/bond/theme.mp3</seo:Custom>
<seo:FbAppId>1234567</seo:FbAppId>
</seo:SeoWidget>
<p>This is my page, now with SEO!</p>
</g:HTMLPanel>
</ui:UiBinder>
If you want to use other meta properties, you can use <seo:Custom property="theproperty">Value</seo:Custom> as a fallback.
Internationalization (i18n)
You can also use ui:msg inside the tags to use i18n messages :
<seo:SeoWidget>
<seo:Title>
<ui:msg description="SEO - MAIN - TITLE">Title</ui:msg>
</seo:Title>
<seo:Description>
<ui:msg description="SEO - MAIN - DESCRIPTION">Description</ui:msg>
</seo:Description>
<seo:Keywords>
<ui:msg description="SEO - MAIN - KEYWORDS">kw1,kw2,kw3</ui:msg>
</seo:Keywords>
<seo:Og>
<seo:OgImage height="480" width="480">http://some.image.url</seo:OgImage>
<seo:OgType typeValue="WEBSITE"/>
</seo:Og>
<seo:FbAppId>1234567</seo:FbAppId>
</seo:SeoWidget>
Although there are no specific og:title and og:description tags, they are copied at runtime from the seo:Title and ``seo:Description` tags.
How it works
When the SeoWidget is attached to the DOM, the content is used to generate <meta> tags. Those tags are then inserted into the <head> section. At the moment, nothing is done when the widget is detached. A good practice is to define specific SEO components in all your views.
Dynamic data
GWT-SEO can also simplify the way you handle meta properties from dynamic data
import com.arcbees.seo.Image;
import com.arcbees.seo.OpenGraph;
import com.arcbees.seo.SeoElements;
import com.arcbees.seo.TagsInjector;
// Other imports...
public class MyViewImpl implements MyView {
interface Binder extends UiBinder<Widget, MyViewImpl> {}
private final Widget widget;
private final TagsInjector tagsInjector;
@Inject
MyViewImpl(
Binder binder.
TagsInjector tagsInjector) {
widget = binder.createAndBindUi(this);
this.tagsInjector = tagsInjector;
}
@Override
public void setProduct(Product product) {
Photo photo = product.getPhoto();
Image image = new Image(photo.getUrl(), photo.getHeight(), photo.getWidth(), photo.getMimeType());
OpenGraph openGraph = new OpenGraph.Builder()
.withImage(image)
.build();
SeoElements seoElements = new SeoElements.Builder()
.withTitle(product.getName())
.withDescription(product.getDescription())
.withOpenGraph(openGraph)
.build();
tagsInjector.inject(seoElements);
}
// ...
}
