Use of javascripts is good for SEO? OR does it have any disadvantages. ??
“Use of Javascript” and “SEO” don’t belong in the same sentence.
There are good ways to use Javascript, and there are bad ways to use Javascript.
The good ways are to enhance the basic functionality of a site - the site should still be usable and have all the essential content without Javascript, but will be better, slicker, easier to use etc for people who do have it.
The bad ways are to create the basic functionality of a site. If the content isn’t all there or the essential features don’t work or people can’t navigate around the site without Javascript, that is a complete failure.
Search engine spiders don’t pay a lot of attention to Javascript. If you’ve used it in a good way, they will still be able to access all of your site, and you’ll be fine. If you’ve used it in a bad way, they won’t be able to access all of your site, and you will suffer as a result. It’s pretty much impossible to use Javascript to improve your search rankings, but if it’s used badly it can seriously harm them.
If i use javascripts then will it be affect negatively on crawling??
If you can still navigate around the site with Javascript turned off, and all essential functions and features still work, then your use of Javscript will not have any noticeable impact on your crawlability or search rankings.
If you get stuck when you turn Javascript off, and you can’t get to some pages or they don’t work properly, search engines will face the same problem and won’t be able to crawl and index your site properly.
I would add that javascript is good when you want to hide something from search engines (and I don’t mean that in a bad way!). But a submenu that is not critical to a website navigation and in some ways duplicates another menu can be created in javascript to avoid any dangers of duplicating in the eyes of search engines
That’s a fair point, but IMX lots of webbies who use Javascript-generated navigation don’t have a plain HTML alternative, rendering some, most or all pages inaccessible without JS. And I don’t think search engines would be at all bothered by having two lots of internal navigation on a page.
Absolutely wrong in an absolute way - read all the posts in this thread which will explain why.
Well put. JavaScript should enhance the site, not operate it.
I thing SE bots ignore the data contains in the script. So no need to worry much about the negative part…
i think it does not matter what kind of coding language you are using as seo really concern with contents and website layout, tags, urls and web presence means backlinks. But your website loading speed does matter which should be optimize…
The search engines can follow and execute some javascript so you need to be careful that thinking because you put a link in javascript it will not be followed or found. Also, the search engines have stated that they do scan javascript sometimes to find links to crawl.
If your java script does not too complex, I think it will not effect
All that needs to be said has been said.
