What is AngularJS?• AngularJS is a structural framework for dynamic web apps. It

lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly. Angular's data binding and dependency injection eliminate much of the code you would otherwise have to write.

AngularJS by other Names• Many dev shops are cloning the features of AngularJS and

creating their own platform…

Popularity of Angular & Others

• 400k sites using AngularJS• 558k sites using BackboneJS• 14k sites using Meteor• 9k site using EmberJS

Source: BuiltWith April 2016

9

Why are Developers Using It?• Developers can write less code than before• Simplified App development by removing program flows and

load order as Angular handles dependencies• MVC components reduce shortcuts and potential breaks• DOM manipulation in directive = more flexible designs

• Simply, Angular has wired up all of the common framework tools and ensures they work together.

10

Why Should We Care?• Developed for “Single Page Apps” • Pages may not have unique URL’s (no URL no links or indexing)

• Most of the text is “Rendered” in browser not in the page• Search Engines can render the page but cannot understand context

and relevance of the content (no text no relevance and no rank)

• Links and Connections are Dynamically Created• Deeps links are added during page load and not static (no links to

follow = no crawl = no index = no ranking)

11

Self Test 1 – Unique URL’s

• When you scroll the page, do the modules have unique URL’s?

12

Self-Test 2 – View Source• view-source:http://www.barbie.com/en-us

Do you see any text or content that would tell the search engine what the page is about?

13

Self-Test 3 – Does Google See Text?• Info:http://www.barbie.com/en-us – View Text-Only

Does Google have any text cached for the page?

14

Self-Test 4 – Page Relevant?• Barbie spy squad site:barbie.com/en-us

Does Google show the page as relevant for the query?

15

Collaboration• Determine the benefits of using AngularJS and the potential

impact on the business

• Collaborate with SEO and Dev and Creative teams to ensure search friendly implementation

Introduction• A number of my clients have had significant

SEO issues using Angular JavaScript• Each of the three anonymous case studies

presented were coded in Angular JS prior to SEO consultation• These SEO issues include:

• Content not being indexed / Blank pages indexed• Links not being indexed / Navigation not being

indexed• Pages not being indexed / Pages being indexed

under the wrong URL• Each of these case studies is in a different

stage of resolution.

20

Client 1• Issue: Content Populated in

Angular JS• Some content seen / Some

content not seen• Cache was blank but specific

string search pulled up page• Recommendation: Recode

affected area• Still unresolved

Sample Footer

This area required a “Click More” action to see the

content. This content was not indexed by search

engines.

21

Client 1• Steps used to Identify the Issue:1)Check Text Cache:

a) Use Cache link from Google Results or

b) Use Cache: command in Googlec) Click on Text Cache Link in Cache

Header d) You may need to use the ESC button

to disable redirectse) Or append &Strip=1 to Cache URL

2)Check for Unique Stringa) Use “inurl” command in conjunction

with unique string in quotes

Sample Footer

22

Client 2• Issue: Page Navigation templates

not being indexed as links (showing up as code)• Slow / Inconsistent of Indexing of

Pages• Links not passing trust and

authority to pages linked from the navigation• Content is correctly indexed• Recommendation: Change

navigation code• Issue unresolved

Google Text Cache:

http://www.doz.com/search-engine/angularjs-index-seo

23

Client 3• Issue: Page content not indexed and pages

not being indexed• Ecommerce site had only 10 pages indexed

and only two product pages• Blank pages considered duplicates• Text cache showed blank page / search for

specific text had no results• Recommendation: Implement Prerender.IO• Results

• 5 pages to 13k+ Indexed• Content Seen and Indexed

• Issue resolved / But there are additional issues

24

Client 3• Additional Client Specific Issues with Prerender.IO Solution:• *Issues not related to Prerender.io solution • Canonical Tags

• Wrong Canonical Tags on • Pagination (Single URL)

• Pagination doesn’t have unique URLs to build fragments from• Make sure rel=next / rel=prev is implemented on both regular URLs and

fragments

25

Making the Case to Management / IT

• Two Potential Scenarios• Already Have Angular JS• Considering Angular JS

26

Making the Case to Management / IT• Already Have Angular JS

• Determine if performance is currently affected using methodologies described earlier

• This is evaluation should always be done following the launch of a redesign that uses Angular JS

• If so, explain potential / current issues to management and IT (use this Webinar)

• Present Documentation to Management with Impact Report

• Create Impact Report with Potential Loss of Revenue / Opportunity for Growth (SEOClarity Forecast Report)

27

Making the Case to Management / IT

• Considering Angular JS• Explain Potential Issues to

management and IT (use this Webinar)• Determine if Functionality is Needed• Create Impact Report with Potential

Loss of Revenue / Opportunity for Growth• Evaluate Potential Solutions• Launch Site with Optimization

Solution in Place• Validate Solution is Working

Onclick events will load the AngularJS site with return false, and keeping static URLs in

the link href attribute value.

If there is no _escaped_fragment_ GET variable, load the AngularJS site.

The loadpage.js has all the instructions for PhantomJS

If there is an _escaped_fragment_ GET variable, run the loadpage.js file using PhantomJS and save it as a plain html file.

The middleware of Prerender.io is what controls the URL rewriting to point the _escaped_fragment_ URLs load from Prerender.io’s server that cached and prerendered the code.

Submit the URLs you want to be cached and prerendered. A token passed in the HTTP headers is used to identify your account.

Technical Implementation for SEO


Developer SEO UserWhy Like? Why Dislike? Whatever Dude!• Great Control Over the

DOM• Data binding• Easy Form Validation• Grouping HTML into

reusable components

• Search engines typically do not read JavaScript code.

• Google, which has a headless browser performs inconsistently in crawling and indexing JavaScript code.

• The page loads fast, and acts like a desktop application. No long page reloading.

• Sites that rank high where the top results are exactly what they were looking for that there is no need to go deeper.

(5) Pre-rendering Services

(1) Don’t Use AngularJS


• 1. Don’t use AngularJS• 2. Static Site Equivalent

• <meta name="fragment" content="!">• ?_escaped_fragment_ 301 redirects to static version.• href values point to static version.• Onclick window.location.href loading AngularJS version with return false

• 3. Initial Static HTML Rendering• AngularJS tags where the content is dynamically added by DOM control, will already

have the content preloaded by server-side scripting.• href values will have unique URLs but with onclick values loading AngularJS version

with return false.

• 4. Headless Browser Prerendering• <meta name="fragment" content="!">• ?_escaped_fragment_ will trigger to load the headless browser. • Caching the page for server efficiency, faster page loading.

• 5. Pre-rendering Service• <meta name="fragment" content="!">• ?_escaped_fragment_ will trigger to load he cached prerendered pages. • The middleware handles the URL rewriting and fetching from the cache source.

Never experienced an AngularJS developer agree. Only for small JS usages.

Never experience as the primary strategy.Experienced as a takeover SEO project

My Favorite, no meta fragment tag, no _escaped_fragment_ , nothing to install.Only experienced with new websites and refactored websites.

Based on industry peers, those that want to stray away from the PhantomJS installation and configuration will use Prerender.io…

…But when a site has a very large amount of pages, and cost goes up, they start considering the headless browser.
