Hi Swati,
Any article which has a long term value, are evergreen and can generate revenue on a regular basis are generally considered as valuable for a website. Remember, your article should be specific to a particle subject. Rather than writing about 2 to 3 different historical events, write an article on 1 specific topic. This reduces the competition and also removes the general nature of an article.
Try to write about a topic in a topic. For example Architecture in Mughal Dynasty, Poetry from the Tang dynasty.
Then write in details about the information about that particular topic. When it comes to history, people who look for detailed information come on to history based articles. So make sure you provide in depth information for the article. IndiaStudyChannel says provide 1000 to 1500 words of rich content for the article.
Provide your own analysis and inference for the article. This step brings authority to your article. Rather than simply giving information already present on the internet and in the books, provide your insight to the article. Give proper headings to the article which state what is present on the internet and what is your inference. A simple heading like "My views" or "My Analysis" would be sufficient.
To summarize, try to create an article which has a comprehensive coverage of the topic. Whenever possible try to create images. You may want to use AI tools to create images and provide courtesy link as to from where the image was generated. History articles are better appreciated when provided with present day maps, but with courtesy links and descriptions.
Lastly, I would suggest of making use of modern tools like Gemini and Krutrim to do a good research on the topic. And present the same in your own words.
In the end, if you are looking to gain cash credits from the article, do keep a note that given the current downtrend of online businesses, cash credits may be low. If you are looking for Google AdSense Revenue generation, things are tight and revenue generation may be low.
But if you are looking to contribute to IndiaStudyChannel's growth, your articles would contribute to the website in the long run. Every penny counts in today's competition created by Search Engines and online presences.
