To understand the impact of JS on SEO, you have to understand what the meaning of JS, JS Basic grammar and other related knowledge, no one you talk to the public about the SEO effect is not in the nonsense, you do not feel that the export of their hearts are empty? Yes, how to be righteous, courteous, Then you must master JS basic syntax, to understand the advantages of JS and JS shortcomings.
First of all, I would like to talk about JS:
JS Benefits:
In fact, this is why the emergence of JS this language is an important reason, JS full name Javascript,javascript is a object-based and event-driven and relatively secure client script language. It is also a kind of scripting language widely used in client Web development, which is often used to add dynamic functions to HTML Web pages, such as responding to user's various operations. This piece of text you may read more blunt, I would like to introduce you should be able to understand, I think you have noticed that the green color of the font, yes this is what we need to understand the point.
First JS is a client script language, you may ask this and SEO have what relationship? can tell you very directly, this relationship is big. Because JS is a client-based scripting language, so it renders the data and action is not required to interact with the database, such as we often see the provincial and municipal linkage, in the registration often encountered Drop-down list provinces, urban areas, county, etc., these data as not often changed, So the large web site is to use JS call, this can greatly reduce the consumption of the server, but also shorten the time to feedback to the user data. Since the page is presented to the user's time shortened, ask if the SEO is relevant, the answer is yes, and this is not the main consideration of SEO, the important purpose of the server and users. In fact, this is the simplest user experience function.
Then also mentioned JS can bring dynamic effects of HTML, we all know that HTML is static Web pages, looks more rigid, many people prefer to be able to move the page, such as the 56 album inside the Merry-go-round these effects once I also downloaded imitation, and the page of the Matrix, At the same time I use JS also developed a similar jinshan typing game. JS can make HTML move up, then have JS HTML page is dynamic website? (What is a dynamic Web site? What is a static web site?)
Finally there is a response to the user's operation, just in fact mentioned a provincial-level linkage function, in the registration we also often see some JS upgrade Ajax efficacy, such as the validation of password length and security, verification code, whether the check for empty, and so on, these work can be done to JS, Not every time the user commits like a database request, greatly reducing the load on the server.
JS Disadvantage:
Talk about JS shortcomings as simple as possible, personally think JS is a difficult to develop difficult to debug script language, write JS code people know that debugging JS is very troublesome opinion things, so the Web engineers get high wages we do not think there is anything unfair, and then is that we all know the JS on the impact of SEO, Frankly I think the impact of JS is not very large, as long as not too much, if the code too much to encapsulate to the JS file call. A few days ready to write an optimization of the JS code of the article, I have not used JS for a long time, and everyone needs to learn. So specially do a blog, after good articles will be submitted to E-commerce Research Center, thank you for your support (contact QQ 915344355).
said the advantages of JS and JS shortcomings, I think you should know when the site development, how to weigh JS when to use, when not to use or less use. A lot of JS on the impact of SEO I think you know more than I do, after all, a lot of people have mentioned, I just did some very few mentioned factors, perhaps my personality problem, I have always insisted that JS SEO is a great advantage, once I was a programmer, completely do not understand SEO, I and a so-called seoer quarrel , he said the site must not use JS, I read the server load on the database to answer him, this debate no one wins who negative, we all retain their views. Indeed JS is more or less a certain impact on the search engine, but as long as you do not use excessive or more advantages than disadvantages.
JS those places do not use it? For example: Navigation, do not for cool to dazzle, and lost the value of the SEO. Of course, many bosses will not consider these, they only want to look good this is also no way to lose, cosmetics industry is typical, either JS navigation or is the whole station flash! in fact there is no need to tangle those places do not use, you only remember a little, the more important to the SEO place, It is best not to appear JS code.
