- Driving Organic Traffic: At the heart of SEO lies the goal of driving organic traffic. Unlike paid traffic, organic traffic is not only cost-effective but also tends to have a higher engagement rate. When your website ranks high on search engine results pages (SERPs), it naturally attracts more visitors.
- Enhancing Credibility: Websites that appear on the first page of search results are often perceived as more trustworthy and credible by users. A higher ranking signals to users that your website is a reputable source of information or services in your domain.
- Understanding User Behavior: SEO isn’t just about optimizing for search engines; it’s also about understanding your users. By analyzing keywords and search trends, businesses can gain insights into what their audience is looking for, allowing them to tailor their content and services accordingly.
- Staying Ahead of Competitors: In a saturated online marketplace, SEO provides businesses with a competitive edge. By optimizing your website for search, you ensure that you remain visible to your audience, even amidst a sea of competitors.
- Adapting to Search Engine Algorithms: Search engines, especially giants like Google, frequently update their algorithms. These updates can significantly impact website rankings. Staying updated with SEO best practices ensures that your website remains compliant with these algorithms, safeguarding your position on the SERPs.
While the benefits of SEO are manifold, integrating it with modern web development frameworks like Angular presents its own set of challenges. As we delve deeper into this guide, we’ll uncover these challenges and provide actionable strategies to ensure that your Angular applications are not just optimized for users but also for search engines.
Challenges with Angular and SEO
It is undeniable that with Angular development one can create dynamic, interactive web applications. However, when it comes to SEO, this very dynamism can pose challenges. Let’s explore some of the primary obstacles developers face when optimizing Angular apps for search engines:
- JavaScript Rendering: Traditional search engine crawlers are designed to read static HTML content. Angular, being a JavaScript framework, generates content dynamically. This means that when crawlers visit an Angular site, they might only see the basic HTML template without the actual content, leading to indexing issues.
- Single Page Applications (SPAs): Angular’s strength in creating SPAs can be a double-edged sword for SEO. Since SPAs load content dynamically without refreshing the entire page, crawlers might not recognize or index the new content, affecting the site’s visibility on SERPs.
- Initial Load Time: Angular apps, especially those not optimized, can have longer initial load times. Search engines consider page speed as a ranking factor, and slower loading times can negatively impact SEO rankings.
- Complexity of the Framework: Angular’s intricate nature means that developers need a deep understanding of the framework to implement SEO effectively. Simple tasks like adding meta tags or creating SEO-friendly URLs can become cumbersome.
- Lack of SEO Tools Integration: Many popular SEO tools are designed with traditional websites in mind. Integrating these tools with Angular apps can be challenging, limiting the SEO capabilities for developers.
While these challenges might seem daunting, the good news is that with the right strategies and tools, Angular apps can be optimized for search engines without compromising on their dynamic capabilities.
Solutions for Angular SEO
Despite the challenges, there are effective strategies and tools available to make Angular apps SEO-friendly. Here’s a comprehensive guide to optimizing your Angular applications for search engines:
Dynamic Rendering
Dynamic rendering involves serving static HTML to search engine crawlers while delivering the usual dynamic content to users. This ensures that crawlers can easily index the content.
Tools like Rendertron or Puppeteer can be used to pre-render pages, ensuring that search engine bots see a fully rendered page.
Setting Titles and Metadata
Titles and metadata provide context about a page’s content to search engines. Dynamic setting of these elements is crucial for SPAs.
Angular provides Title and Meta services that allow developers to dynamically set and update these elements based on the content.
Setting up Title and Meta Services
To set up Meta Services, first Angular Universal is needed. You can import Angular Meta service from the app/app.component.ts file of Angular Universal app. The service lets you add fields such as robots, keywords, date and viewport.
To import Angular Meta Service:
Run the command:
import { Meta } from ‘@angular/platform-browser’;
Then inject private metaTagService: Meta in the constructor and use addTags() for configuration of the given HTML meta attributes:
@Component ({
selector: ‘app-root’,
templateUr1: ‘./app.component.htmI’,
styleUrls: [‘ ./app.component.css’]
})
export class AppComponent implements OnInit {
constructor(
private metaTagService: Meta
) { }
ngOnInit() {
this.metaTagService.addTags([
{ name: ‘keywords’, content: ‘Angular SEO, Angular Universal’ },
{ name: ‘robots’, content: ‘index, follow’ },
{ name: ‘author’, content: ‘Ronak Patel’ },
{ name: ‘viewport’, content: ‘width=device-width, initial-scale=1’ },
{ name: ‘date’, content: ‘2021-05-17′, scheme: ‘YYYY-MM-DD’ },
{ charset: ‘UTF-8’ }
]);
}
}
SEO Title and Meta Description
Title, Meta can be imported from @angular/platform-browser . Add the following code to app/components/add-car/add-car components.ts file
Import { Title, Meta } from ‘@angular/platform-browser;
@Component({
selector: ‘app-add-car’,
templateUrl: ‘-/add-car.component.htmI’,
styleUrls: [‘ ./add-car.component.css’]
})
export class AddCarComponent implements OnInit {
title = ‘Add Car – Angular Universal Car App’;
constructor(
private titleService: Title,
private metaTagService: Meta
) { }
ngOnInit() {
this.titleService.setTitle(this.title);
this.metaTagService.updateTag(
{name: “description*, content: “Add car template’ )
);
}
}
Angular Universal
Angular Universal offers Server-Side Rendering (SSR), ensuring that the application displays quickly, improving user experience and making it crawlable by search engines. By implementing Angular Universal, the application’s content is rendered on the server, making it instantly available for both users and search engine bots.
Angular Universal uses the TransferState API to transfer content from the server used for rendering to the browser. The application layer is preserved, while the second layer takes care of the rendering. The Architecture of Angular Universal is as follows:
Angular Universal can generate a file representing a Node server called server.ts file. An isomorphic application is derived from this process- one in which rendering takes place on the server end while navigation takes place on the client end.
Manual Prerendering using Command Line
To install the prender:
<l> npm install angular-prerender –save-dev <l>
Now, for prerendering your application:
First, use the following command on the project:
<l> npm run prerender<l>
Use guess parser to determine the application routes. A prerender builder allows developers to specify the routes of those pages of the site that they would like to render in advance. This builder can be found in the angular.json file of your website.
For example:
“prerender”: {
“builder”: “@nguniversal/builders:prerender”
“options”: {
“browserTarget”; “universal-app:build:production”,
“serverTarget”: “universal-app: server :production”
“routes”: [
“/”,
“/about-us”
” /contact-us”
]
}
“configurations”: {
“production”: {}
}
Meta Tags in Angular
Meta tags provide additional information about a webpage to search engines. In Angular, these can be dynamically set and updated.
Here’s a list of some commonly used Meta Services by Angular:
| Meta Tags | Description |
| addTag() | To include one meta Tag |
| updateTag() | Updates meta Tag in Angular Component |
| getTags() | For getting HTML Element for any specified meta selector |
| removeTag() | For removing meta tags for any specified selector. |
| removeTagElement() | For removing meta tag for a specified HTML Element |
| addTags() | To include more than one meta tag in angular components. |
Using Angular’s Meta service, developers can add, update, or remove meta tags based on the content being displayed.
Angular SEO Checklist
Ensuring that your Angular application is SEO-friendly requires a systematic approach. Here’s a checklist to guide you through the optimization process:
- Server-Side Rendering (SSR): Ensure you’re using Angular Universal for server-side rendering. This ensures that search engine bots can crawl and index your content effectively.
