I have created a new site with a new niche, just have a question, What is better for seo, alot of small articles with 150 to 200 words or long articles with 500 words ?
both are good but to have the same result, you should write 5 100 words articles or 1 500 word article to get the same result
You don't have to choose one or the other. I have articles of varying lengths between 150 and 700 words ranking at the top of Google. Mix it up.
If you plan to submit your articles to article directory then keep your article atleast of 500 words; because most of the directory don't accept less then 500 words & if you dont want to submit your article to such directory then length does not matter. IMO good luck
Articles having less or more than 500 words may attract the search engines as well as for the readers compared with 100 words articles. However, small articles may cover several topics within a single page.
