SeoTags generates All SEO Tags you need such as meta, link, Twitter card (twitter:), Open Graph (for Facebook) (og:), and JSON-LD schema (structured data).
See https://mjebrahimi.github.io/SeoTags/ for more info.
PM> Install-Package SeoTagsEverything you need to do is to configure the SeoInfo object and render it in your _Layout.cshtml.
This configuring can be done by setting the properties of the SeoInfo object in three ways:
- When registering your services using
services.AddSeoTags(seoInfo => { ... })method. Html.SetSeoInfo(seoInfo => { ... })method in your.cshtmlviews (Mvc or RazorPages)HttpContext.SetSeoInfo(seoInfo => { ... })method anywhere you access theHttpContextobject (for example in your mvc Controller/Action or razor-pages PageModel)
There are general options that are constant for your entire website (not specific to a certain page), such as Website Title, Twitter ID, Facebook ID, OpenSearch URL, feeds (RSS or Atom), etc...
Usually, these values are set when registering services using services.AddSeoTags(seoInfo => { ... }) method.
//Register your services
app.Services.AddSeoTags(seoInfo =>
{
seoInfo.SetSiteInfo(
siteTitle: "My Site Title",
siteTwitterId: "@MySiteTwitter", //Optional
siteFacebookId: "https://facebook.com/MySite", //Optional
openSearchUrl: "https://site.com/open-search.xml", //Optional
robots: "index, follow" //Optional
);
//Optional
seoInfo.AddFeed(
title: "Post Feeds",
url: "https://site.com/rss/",
feedType: FeedType.Rss);
//Optional
seoInfo.AddDnsPrefetch("https://fonts.gstatic.com/", "https://www.google-analytics.com");
//Optional
seoInfo.AddPreload(new Preload("https://site.com/site.css"),
new Preload("https://site.com/app.js"),
new Preload("https://site.com/fonts/Font.woff2"),
new Preload("https://site.com/fonts/Font_Light.woff2"),
new Preload("https://site.com/fonts/Font_Medium.woff2"),
new Preload("https://site.com/fonts/Font_Bold.woff2"));
//Optional
seoInfo.SetLocales("en_US");
});
//...To render the output SEO Tags call Html.SeoTags() method in your _Layout.cshtml.
This method has two overloads, one with a SeoInfo argument (if you need to pass a new arbitrary instance of the SeoInfo object), and one without an argument that retrieves the configured SeoInfo object from your previous registered services.
<!DOCTYPE html>
<html lang="en">
<head>
<!-- Remove these tags from your _Layout.cshtml
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

<!-- SeoTags generates all of these for you -->
@Html.SeoTags() <!-- 👈 Add this line -->There are some specific SEO info that you may want to set for a certain page, such as such as Page Title, Page Description, Page Keywords, Page URL, Publish Date, Modified Date, Image Info, Page Type etc...
To do this, call Html.SetSeoInfo(seoInfo => { ... }) method in your .cshtml views to set specific desired SEO info for that page.
You can do the same by calling HttpContext.SetSeoInfo(seoInfo => { ... }) anywhere you access to HttpContext object (for example in your mvc Controller/Action or razor-pages PageModel)
@{
// Remove these line from your views
// ViewData["Title"] = "Page Title";
Html.SetSeoInfo(seoInfo =>
{
seoInfo.SetCommonInfo(
pageTitle: "SEO Tags for ASP.NET Core",

keywordTags: new[] { "SEO", "AspNetCore", "MVC", "RazorPages" }, //Optional
seeAlsoUrls: new[] { "https://site.com/see-also-1", "https://site.com/see-also-2" } //Optional
);
seoInfo.SetImageInfo(
url: "https://site.com/uploads/image.jpg",
width: 1280, //Optional
height: 720, //Optional

//mimeType: "image/jpeg", //Optional (detects from URL file extension if not set.)
