How to dynamically change a web page's title? (12)

Update: as per the comments and reference on SearchEngineLand most web crawlers will index the updated title. Below answer is obsolete. but the code is still applicable.

You can just do something like, document.title = "This is the new page title.";, but that would totally defeat the purpose of SEO. Most crawlers aren't going to support javascript in the first place, so they will take whatever is in the element as the page title.

If you want this to be compatible with most of the important crawlers, you're going to need to actually change the title tag itself, which would involve reloading the page (PHP, or the like). You're not going to be able to get around that, if you want to change the page title in a way that a crawler can see.

I have a webpage that implements a set of tabs each showing different content. The tab clicks do not refresh the page but hide/unhide contents at the client side.

Now there is a requirement to change the page title according to the tab selected on the page ( for SEO reasons ). Is this possible? Can someone suggest a solution to dynamically alter the page title via javascript without reloading the page?

But in order to get the SEO befits

You need to do a page reload when the page changes so that the search engine's see the different titles etc.

So make sure the page reload works first then add document.title changes

I just want to add something here: changing the title via JavaScript is actually useful if you're updating a database via AJAX, so then the title changes without you having to refresh the page. The title actually changes via your server side scripting language, but having it change via JavaScript is just a usability and UI thing that makes the user experience more enjoyable and fluid.

Now, if you're changing the title via JavaScript just for the hell of it, then you should not be doing that.

I want to say hello from the future :) Things that happened recently:

  1. Google now runs javascript that is on your website1
  2. People now use things like React.js, Ember and Angular to run complex javascript tasks on the page and it's still getting indexed by Google1
  3. you can use html5 history api (pushState, react-router, ember, angular) that allows you to do things like have separate urls for each tab you want to open and Google will index that1

So to answer your question you can safely change title and other meta tags from javascript (you can also add something like if you want to support non-Google search engines), just make them accessible as separate urls (otherwise how Google would know that those are different pages to show in search results?). Changing SEO related tags (after user has changed page by clicking on something) is simple:

if (document.title != newTitle) {
    document.title = newTitle;
$('meta[name="description"]').attr("content", newDescription);

Just make sure that css and javascript is not blocked in robots.txt, you can use Fetch as Google service in Google Webmaster Tools.


One way that comes to mind that may help with SEO and still have your tab pages as they are would be to use named anchors that correspond to each tab, as in:,, etc.

You would need to have server side processing to parse the url and set the initial page title when the browser renders the page. I would also go ahead and make that tab the "active" one. Once the page is loaded and an actual user is switching tabs you would use javascript to change document.title as other users have stated.

The code is
document.title = 'test'

The simplest way is to delete <title> tag from index.html, and include

<title> Website - The page </title></head>

in every page in the web. Spiders will find this and will be shown in search results :)

Use document.title. It will be useful for most things, but it will destroy SEO on your website.


document.write("title - " + document.title + "<br>");
document.title = "New title here!";
// Notice: this will defeat purpose of SEO. Not useful for SEO-friendly sites.
document.write("title - " + document.title + "<br>");
body {
  font-family: Consolas, 'Courier New', monospace;
<!DOCTYPE html>
  <head><title>Old title</title></head>

Use document.title.

See this page for a rudimentary tutorial as well.

You can use JavaScript. Some bots, including Google, will execute the JavaScript for the benefit of SEO (showing the correct title in the SERP).

document.title = "Google will run this JS and show the title in the search results!";

However, this is more complex since you are showing and hiding tabs without refreshing the page or changing the URL. Maybe adding an anchor will help as stated by others. I may need to retract my answer.

Articles showing positive results:

Don't always assume a bot won't execute JavaScript. Google and other search engines know that the best results to index are the results that the actual end user will see in their browser, including JavaScript.

You'll have to re-serve the page with a new title in order for any crawlers to notice the change. Doing it via javascript will only benefit a human reader, crawlers are not going to execute that code.
