Noscript tags: what are they and how do they affect SEO?

JavaScript is a programming language that is very useful for web design and allows you to display a lot of dynamic elements. However, it may happen that the user’s web browser does not support JavaScript or this support is disabled. Then it is worth using the noscript tags. What are they, how do they influence positioning and how to use them effectively on a website?

What are noscript tags?

Google robots have a problem with efficient rendering of elements implemented on the website in JavaScript. However, the algorithm is constantly being developed and now, when JavaScript elements appear on the page, the content of the web page is indexed by more advanced robots. Even so, some SEO specialists recommend using the noscript tag. This is an HTML tag (code snippet) that causes alternative content to be displayed to users who have disabled Javascript or whose browser does not support this language. In theory, this should be a good solution for website positioning. However, it turns out that this is not always the case, and improper use of noscript tags can harm your website’s SEO.

Where should you use noscript tags?

Noscript tags are used to mark up dynamic page content, that is, one that requires JavaScript to display. They were very useful when Google’s crawlers were unable to read the content in JavaScript. Currently, Google crawlers are coping with this challenge, but they’re not perfect, and it’s still worth using noscript tags to tag content found in:
– sliders,
– according drop-down lists,
– the case of pagination (paging).

Noscript, javaScript tags and SEO – do crawlers read the content contained in the noscript tag?

In 2013, Google announced advances in rendering JavaScript content by Google robots. The robots are getting better at this, but still they don’t read JavaScript content as well as it does in HTML. To make the task of Google robots easier, noscript tags are used. However, it is worth placing in them exactly the same content as that in JavaScript – otherwise, the action may be considered inconsistent with Google’s guidelines. Until a few years ago, many webmasters used noscript tags for keyword placement. This is a bug that can result in penalties from Google. If the content is crucial for the positioning of the page, it should be included in the HTML content.

Advantages and disadvantages of noscript tags

By using the noscript tag:
– you make it easier for Google robots to read JavaScript content,
– you provide a better experience for users whose browsers do not support JavaScript or who have disabled JavaScript.

However, implementing noscript tags requires more time, money, and effort. What’s more, adding new elements increases the page code. The more complex the page code, the longer the site load time (which is a ranking factor), but if you add noscript tags, the expansion should not significantly affect the efficiency and speed of the page.

However, incompetent use of noscript tags can have a negative effect on the positioning of the page. If a message prompting the user to turn on JavaScript support is displayed on each of your pages on your site, your page may frustrate the user when they encounter it and not be able to display its content. This can increase your bounce rate and reduce your conversion rate.

How to use noscript tags in order not to limit positioning effects? Take advantage of our tips.

Use noscript tags only where necessary.
Make sure the content of the noscript tag accurately reflects the content of the JavaScript content.
Don’t put really important content in the noscript content, relevant to the user and Google robots – put it in HTML, which is better understood by Google.
Do not embed links in the noscript content – Google robots may treat them as spam because developers have used the noscript tag in the past for activities against webmaster guidelines.
– If you need to use the noscript tag on different subpages, make sure that the content of the messages is different.
You can apply a message prompting you to enable JavaScript in graphic form. Thanks to this, Google robots will not index the text content and will not display it in organic search results.
