Basic understanding of JavaScript has become an important skill for an SEO professional today, although the recent relationship between these two disciplines is highly debated. The important point between SEO and JavaScript is whether the search engine's crawler can sense the content of a webpage in a way that actually judges the user experience.

Although HTML works with Php, CSS, etc. can be read directly by the crawler, but can not be accessed by JavaScript. Google's crawl bot will first parse the DOM (the DOM and the abstract of the Document Object Model) and then read the page display.

  • JavaScript is a programming language used to make pages. The web is more dynamic and interactive. And it is possible to specialize JavaScript into HTML documents or create links to it.
  • HTML stands for Hypertext Markup Language. It is a content organization that provides website structure such as Title, H1 H2 tags, Meta description and other static content.
  • AJAX is JavaScipt and XML asynchronous. Basically it updates the content without refreshing the whole page. AJAX allows applications and website servers to communicate without the intervention and the current page.

However, beginning in the second quarter of 2018 Google will no longer need AJAX to display web based Java Script again. And a modern SEO person should also have a basic understanding of the DOM. You can think of the DOM as a tool used by Google to discover and analyze web pages.

Google first received an HTML document and identified sections from its JavaScript. Then the browser initializes the DOM, now lets the search engine display the page.

Allows the search engine to view your JavaScript.

The Robots.txt file is set to provide the search engine. Google with appropriate data collection opportunities. If you block the bot from finding and reading JavaScript, the page will appear different from the web crawl bot than the user.

This means that the search engines will not get the user experience. and Google can explain the above actions as cloaking, shady. And the best approach is to provide web crawlers with all the resources they need to see the site in the same way and most accurately as the user.

And also consider Hide files from the Google bot and give them access to files.

Internal Link

Internal Link is a powerful SEO tool used to display with the search engine architecture. Your website and point to the content or important web pages.

The advice here is to use internal links should not try to change the JavaScipt event upon mouse click. There are URLs that can appear and gather information by itself, but the Google bot will not appreciate this link for your site navigation.

So the site would be better if you Implement internal links using common link tags in the DOM or HTML to provide a better user experience.

URL structure

JavaScipt-based web pages are used to Identifies segments within the URL. But hashes (#) and hashbangs (#) are not recommended by Google.

A highly recommended method is the pushState history API. It updates the URL in the address bar and allows JavaScript sites to use clean URLs. A clean URL called Friendly URL includes plain text and is easy to understand for non-proficient users.

Consider using pushState for a website that uses page scrolling, so the URL updates every time a user visits. Access a new section of the page. In a perfect render, the user can refresh the page while maintaining exactly the same position.

Website Testing

Google can crawl and understand many forms of JavaScript, although some of these forms may be more difficult than others. This is a test by Bartosz Gozalewicz showing how Googlebot interacts with JavaScipt on different frames.

This study helps us understand when it is time to worry and act more proactively. However it is always better to anticipate possible mistakes and problems to avoid them. So why do not you do some experiments?

Follow these two basic steps to make possible errors:

  • Check that the content on your site appears in
  • Check out a few pages to make sure that Google can index your content index.

It's important to find out if Google can see your content and JavaScript in robots. txt or not, and analyze it properly. So consider manually checking the content and fetching it with Google to see if your content appears.

If you've completed all your experiments and the results look promising The appointment was so great. But what if something does not work?

If there are any signs that Google can not read your content in a way, call the Google support team for help. In the process of supporting HTML snapshot to rescue when the worst situations can occur.

HTML Snapshot

Google introduced the HTML snapshots in 2009 and it was no longer It's a very long story and an ongoing topic.

One thing you should know is that Google still supports HTML snapshots, although it has identified them as weak. Elements to “dodge”

HTML snapshots may be needed in some situations. For example if search engines can not capture JavaScript on your website, then you can provide them with an HTML capture. This is better than no documentation to authenticate with Google.

And there is a website for displaying HTML snapshots for bots and users. Note that Google strives to see exactly the same experience as the user. Better yet, provide an HTML snapshot for the search engine spider. However, do so only in cases where there is a problem with JavaScript and can not contact your support team.

Web page latency

When a browser creates a DOM using an HTML document, The browser loads the majority of the resource exactly as it is in the HTML document.

If a large file exists at the beginning of an HTML document, the browser downloads the file first and all other information is retrieved. Appears later with a noticeable delay.

The key idea behind Google's key display paths is that it downloads the first important pieces of information to users. Another way to put the most essential content for the user in the first appearance screen.

If your JavaScript file or some unnecessary resources slow down the download speed of the website then you can block JavaScipt. display. This means that your pages are likely to appear faster, but JavaScipt code is slowing them down.

It's a good idea to check how long it takes to load a page, which must have speed information. pages or other similar tools. Analyze the results of whether or not JavaScript blocks the display.

Here are some top solutions to this problem:

  • Adding JavaScript to HTML
  • Adding “async” attribute to HTML to make your JavaScript asynchronous.
  • Reducing JavaScript Elements in HTML Documents

Another thing to keep in mind is that when trying to improve your website's content, remember the basic rules of JavaScript. JavaScript. You should keep in touch with your web code team to ensure that any changes do not disrupt the user experience.

Conclusion

Search engines are constantly evolving, so they will not. Have any doubts when understanding your JavaScript better and faster in the future.
