OK so I'm building a site and have like 20 articles to add as fas as SEO is concerned is their an optimal way to add the content? add all 20 pages at one time add 1 article a day for 20 days space it out about 3 articles/week for 2 months it doesnt matter you're being overly cautious! ok just curious as I have always wondered about this ...
You should always finish your site before you start major SEO operations, always take SEO in to view when developing your website, but having more content is always best to rank correctly.
you are putting your self into nothing but wasting your time..why don't you take it one at a time.. i think its more convenient and effective.
The main thing to focus on is unique content. Be careful of duplicate content and make good use of keywords (not stuffing) and keyword phrases throughout your content.
