What is better for SEO? One long page or several short web pages?
If web page is too big or long, they rank lower than pages that are small and focused.
Visitors do not like scrolling. Pages with really lot of text below the fold will
lose many visitors because of that.
With several pages you can link each other and pages will have few links already when Google index them. With one page you can’t do that.
Pages that are directly relevant to the keywords equals better ranking. And it’s easier to make a page more relevant if it’s just about one keyword.
With several pages you can target several keywords better.
So, the cut long story short, go with few shorter rather then with one long page if you are concern about SEO optimization.
