SEO engineers to share the impact of JS optimization

SEO engineers talked about the shortcomings of JS as simple as possible, personally think that JS is a hard-to-debug development of scripting language, wrote JS code, people know that SEO engineers debugging JS is a very troublesome opinion things, so the web engineer to take High wages we do not think there is any unfair, and then we all know the impact of JS on SEO, frankly I think the impact of JS is not great, as long as not too much, if the code as much as possible encapsulated into the JS file Call can be. A few days ready to write an article to optimize the JS code finishing, SEO engineers have not used JS for a long time, and everyone needs to learn.

First of all JS is a client-side scripting language, you may ask what is the relationship with SEO? Can tell you directly, the relationship went big. Because JS is a client-based scripting language, the data and actions it presents do not need to interact with the database. For example, we often see the provincial-level linkage at the time of registration, often encounter drop-down list provinces, Urban, county, etc., these data are not often changed, so large sites are using JS calls, so that you can greatly reduce the server consumption, but also shorten the time to feedback data to the user. Since the page is presented to the user's time is shortened, I ask whether SEO related, the answer is yes, and this is not the main consideration SEO, the important purpose is still in the server and the user. In fact, this is one of the most simple user experience features.

In fact, this is why JS language is an important reason, JS full name JavaScript, JavaScript is based on an object-based and event-driven and relatively secure client-side scripting language. It is also a scripting language that is widely used for client-side web development and is often used to add dynamic functionality to HTML pages, such as responding to user actions. This text we may read harder, I introduce a little we should be able to understand, I think you all noticed this paragraph added a green font, yes, this is what we need to understand.

Said the advantages of JS and the shortcomings of JS, I think you should know when the site development, how to weigh JS when to use, when not to use or less to use. A lot of JS on the impact of SEO I think you know better than I, after all, many people have mentioned, I just did a few here just mentioning the factors that may be my personality, I always insisted JS SEO is great The benefit, when I was a programmer, did not understand SEO at all, and I quarreled with a so-called SEOer who said he could not use JS inside the site, and I answered him for the reason that the database read the server load, which was not debated Who wins or who wins, we all retain our point of view. Indeed, JS is more or less a certain impact on the search engine, but as long as you do not over-use or more advantages than disadvantages.

Finally, SEO engineers also respond to the user's actions, just in fact mentioned a provincial-level linkage function, SEO engineers in the registration we often see some JS AJAX upgrade features, such as verification password length and security, verification code, Is empty check, etc., these tasks can be completed to JS, do not have to submit every time like a database request once, greatly reducing the load on the server.
