First, fix the landing page - you need to present value before you can expect a conversion. This means making something that is interesting and aesthetically pleasing.

Second, if this is a business idea, I'm not sure how you monetize this. Is it ads from user visits? If so, you are going to need a ton of user visits.

Third, up the social media game. If you want visitors you need to make these articles/timelines sharable and unique.

Fourth, I'm in agreement with others here when they say this is not a timeline. Medium/Wordpress provide the same functionality. This can be replicated in Wordpress/Medium just be including subtitles with dates in between paragraphs.
