To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots. When a search seomag engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed, and will instruct the robot as to which pages are not to be crawled. As a search engine seomag crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific seomag content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because seomag those pages are considered search spam. |

SEO companies that employ overly aggressive techniques can get their client websites banned from the search results. In 2005, the Wall Street Journal profiled a company, Traffic Power, which allegedly used high-risk seomag techniques and failed to disclose those risks to its clients.[14] Wired magazine reported that the same company sued blogger Aaron Wall for writing about the ban.[15] Google's Matt Cutts later confirmed that Google did in fact ban Traffic seomag Power and some of its clients.[16] Some search engines have also reached out to the SEO industry, and are frequent sponsors and guests at SEO conferences, chats, seomag and seminars. In fact, with the advent of paid inclusion, some search engines now have a vested interest in the health of the optimization community. Major search engines provide information and guidelines to help with site optimization.[17][18][19] Google has a Sitemaps program[20] to help webmasters learn if Google is having any problems indexing their website and also provides data on Google traffic to the website. Yahoo! Site seomag Explorer provides a way for webmasters to submit URLs, determine how many pages are in the Yahoo! index and view link information.[21] |

Site owners started to recognize the value of having their sites highly ranked and visible in search engine results. According to industry analyst seomag, the earliest known use of the phrase "search engine optimization" was a spam message posted on Usenet on July 26, 1997.[2] Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag, or index files in engines like seomag. Meta tags provided a guide to each page's content. But using meta data to index pages was found to be less than reliable seomag because the webmaster's account of keywords in the meta tag were not truly relevant to the site's actual seomag keywords. Inaccurate, incomplete, and inconsistent data in meta tags caused pages to rank for irrelevant searches.[3] Web content providers also manipulated a number of attributes within the HTML source of a page in an attempt to rank well in search engines.[4] |

Webmasters and content providers began optimizing sites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all a webmaster needed to do was submit a page, or URL, to the various engines which would send a spider to "crawl" that page, extract links to other pages from it, and return seomag information found on the page to be indexed.[1] The process involves a search engine spider downloading a page and storing it on the search engine's own server, where a second program, known as an indexer, extracts various seoamg information about the page, such as the words it contains and where these are located, as well as any weight for specific words and all links the page contains, which are then placed into a scheduler for crawling at a later seomag date. |
