Why not to post more than 2 articles in a day

If you are new blogger and willing to write more than 10 articles in day then I suggest posting article in older dates or in future days.

If you post more than 2 articles in a single day then Google will consider them as scam article as it think they are copied from other website.

If you post more than 15 article in week then your blog archive for the week will not have proper keyword density for the entire week and leads to low rank in the search results.
If new blogger accepts article from other writer then care should be taken about the how unique they write and whether they have some internal links for the websites.

I suggest new blogger not to submit article by using fetch as Google instead wait for Google robots to crawl the blog as search engine re crawls a new website within 2 hours of posting fresh article.

If you have more and more post to be published for the day then post then in earlier date by using setting at blog post under schedule time of article.

If your blog maintain the code of posting less than 20 article in week then Google consider all article free from plagiarism and index them according to the weeks they belongs and have good alexa rank for such blogs and website. 

Google also re crawls website which have reader from every country as it loves issues related to universal in nature. So try to find out the new blogs which post unique article and leave a link of your blog by commenting at the comment section and ask the blog owner to keep the link.

Fresh blogger if you have the article not related to your blog then post then in other blogger who write on such issues and ask him to give link to your main page.
