12. A method comprising: obtaining a Document Object Model of a web page; identifying Document Object Model elements, of the Document Object Model, associated with native advertisement placement candidate containers, comprising: identifying, with the Document Object Model, HTML tag sequences that include at least L tags, where L is a specified number, repeat at least R times, where R is a specified number, and all correspond to a single element of the Document Object Model: constructing a suffix tree of a string of tags comprising all tags in the Document Object Model; performing a traversal of the suffix tree, beginning with a root node, and computing, for each node that is non-root and non-leaf, a number of leaf nodes of the each node; analyzing the Document Object Model by performing a recursion of the suffix tree and pruning the recursion when the number of leaf nodes of the each node is less than R; and based at least in part on the analysis relating to the Document Object Model, and utilizing at least some of the identified elements, determining, within the Document Object Model, one or more native advertisement placement candidate containers.
