5. jQuery Pages Load Faster.

Google and other search engines using page load time as one of the many factors affecting SEO. (More on that later.) For this, and many other, reasons, every developer should strive to make code as light and concise as possible.

The best way to do this is to reduce the size of your code. If your site is coded with an HTML and CSS base, you can easily make uniform adjustments to your code that will reduce the size. Like CSS, jQuery files are generally stored separately from the Web page itself. This lets developers make modifications across the entire site through one central repository instead of search through folder structures. This is a core benefit of CSS coding-and it is a proven success.

In addition, jQuery gives you the option of loading Div tags only when you need them. If you are taking measures to improve the speed of your website, then you may consider loading only the necessary Div tags needed for your page load event. This way, you can display only what a user needs to see right away and have the rest of your division elements load as they are needed.

6. jQuery Can Be SEO Friendly.

You may have the most appealing site, but is it worth it if you sacrifice style for SEO? The way you code your site greatly affects the way it can be found in Google, Bing and other search engines.

As noted, jQuery can be optimized for search engines, and there are a lot of plug-ins available to aid developers in this task. Embedding your jQuery elements using unordered lists is an SEO friendly practice that works well.

For example- < UL >Render your jQuery output here< /UL >

The unordered list is a classic HTML tag that has been around for years-search engines will pick up or recognize < UL > tags much faster than a custom element or tag-and will still be utilized in HTML5.

Another SEO advantage of the HTML5-jQuery combo that's worth mentioning is that animations can be loaded with keywords that can be read by search engines.

Why You Need jQuery

Let's recap some of the advantages to using jQuery in your next Web development project.

  • The price is right. The jQuery library is free.
  • It's light. Since jQuery pushes content to the client, it therefore reduces the wait time for server response. Plus, it's smaller than Flash, so it results in smoother playbacks and less errors.
  • It works anywhere. HTML5 is cross-browser compatible-it will work on any browser, mobile phone or tablet, and even on Apple devices.
  • There's a low learning curve. Since it's based on plain old JavaScript, developers can learn jQuery fast.
  • Finally, jQuery is SEO friendly and CSS3 compliant.

In the future, your company will have to deliver content to a variety of different platforms, including desktops, tablets and smartphones, not to mention the advent of smart TVs and other connected devices. The 1-2 punch of HTML5 and jQuery is one of the best solutions for this type of development.

Since jQuery is a major component of HTML5, it is worth the time, money and effort for your developers to learn jQuery now. This library can deliver stunning effects with little coding-and, with more and more HTML5 integration, it will be a huge part of the future of Web development. If your goal is to build a site or Web app that is engaging and interactive, then jQuery is a necessary tool for your toolbox.
