General directories have a wide range of categories and subcategories under which all kinds of sites, however specific, can be submitted. Besides this, general directories have a larger audience and a wider reach than niche directories. Having said that, it is also worthwhile to submit to niche directories because they are more relevant and directly target a specific audience or industry. However, the number of niche directories available is much smaller than the number of general directories, which is why it is worth submitting to general directories as well, in order to support the links that are received from niche directories.
