Often, the term "search engine" is misused to describe both directories and pure search engines. In fact, they are not the same thing; the difference lies in the way result listings are generated.

• directories (mostly human-edited catalogs);
• hybrid engines ( META engines and those using other engines' results);

1997 – 1999 were the early years of search engine era. SEO mainly consisted of submitting your sites to the search engines. These "voices from the past" are still heard today when this or that SEO company and / or automatic submitting software will claim to do search engine promotion for you by submitting your site to hundreds and thousands engines and directories. The search engines' indexing programs, called "robots" or "spiders", looked through all of the HTML code of a page and used some page ranking algorithms that they kept in secret.
