Indexing & JavaScript
Historically, there were concerns that search engines only indexed the HTML source returned from the server, potentially missing content generated by JavaScript. However, search engines now incorporate JavaScript execution as part of their rendering process. This means that pages are fully loaded and indexed, including JavaScript-generated content.
While server-side rendering remains a recommended practice by search engines, Tweakwise JS improves performance compared to the existing solutions in the platforms. This mitigates concerns related to JavaScript's impact on SEO, with many users experiencing positive effects on search engine rankings due to improved page performance.
User Experience and performance
In recent years, Google has put more value on user experience (UX) and performance, making these aspects crucial for effective SEO strategies. Improving website performance leads to a smoother user experience, which can positively influence search rankings.
Tweakwise JS enhances both performance and UX, which in turn can have a positive impact on SEO.
To further enhance SEO capabilities, Tweakwise JS is actively developing features to meet additional SEO requirements. Updates on these developments will be communicated through our changelog.
