14Costs
- The web is growing quicker than it can be
indexed. - Search engines slow down because of indexing new
web pages - Queries currently limited to keywords, resulting
in matching random words scattered across large
pages (as opposed to limiting matches within a
paragraph or phrase)
Description SMCR BCV
Competition Future Summary
15Costs
- Many dynamically generated sites are not
indexable, resulting in the invisible web - Some search engines do not rank by relevance, but
rather by how much the websites pay - Hundreds of generated sites use tricks to
manipulate a search engine into displaying them
higher in results
