Search Engine Optimization ( Seo )

For this assignment, I was allowed to improvise on a provided base code to develop a functioning web crawler. The web crawler needed to accept a starting URL and then develop a URL frontier queue of “out links” to be further explored. The crawler needed to track the number of URLs and stop adding them once the queue had reached 500 links. The crawler needed to also extract text and remove HTML tags and formatting. The assignment instructions offered using the BeautifulSoup module to achieve those goals, which I chose to do. Finally, the web crawler program needed to report metrics including the number of documents (web pages), the number of tokens extracted and processed, and the number of unique terms added to the term dictionary.

A Web crawler, sometimes called a spider, is an Internet bot that systematically browses the World Wide Web, typically for the purpose of Web indexing. Crawlers can validate hyperlinks and HTML code. They can also be used for web scraping. Crawlers consume resources on the systems they visit and often visit sites without approval. Issues of schedule, load, and "politeness" come into play when large collections of pages are accessed. Mechanisms exist for public sites not wishing to be crawled to make this known to the crawling

In layman’s terms, Search Engine Optimization or SEO is essentially tweaking your website so that it comes up naturally or organically for search results in Google, Yahoo Bing or any other search engine.

What the spider does is it works none stop to retrieve information so that when the user searches for something, they will get the information they searched for. There is also the returned information that is given every time when a word or a phrase is searched. The number that is given for every search shows how many times it has be searched or used before on the web. The engines have operators Boolean and Logical, these two operators are like filters. Boolean works symbols such as +/- signs that allow you to place with the searched word or phrase what it does is; filters that only web results with searched word are shown. The Logical operators implement “and”, “or” and “not” in the search engines. In short the operators are created to narrow your search result, or possibly widen. Searching on the web the student must know that having to use fully sentences

Crawler must avoid the overloading of Web sites or network links while doing its task. Unless it has unlimited computing resources and unlimited time, it must carefully decide what URLs to scan and in what order as it deals with huge volumes of data .Crawler must decide how frequently to revisit pages it has already seen, in order to keep its client informed of changes on the

First, a User types a domain or web address, let’s say “www.google.com” into a browser. The browser sends a message to the network asking for help, this is called query.

The World Wide Web (WWW or Web) is an application that relies on the Internet to function. The WWW was first developed as a concept of creating a “universal database of knowledge”, a way to link information easily for anybody to access (Johnson, 1995). The World Wide Web began in 1989. A simple system was created to use hypertext to transmit documents of information across the Internet (Johnson, 1995). The language used to create documents on the Web is known as HTML (HyperText Markup Language). HTML creates the documents and pages that

Nevertheless, it has obtained gigantic awareness best in the up to date years [41-58, 60-64]. Targeted crawlers avoid the crawling method on a certain set of issues that characterize a narrow area of the online. A focused or a topical internet crawler makes an attempt to download websites critical to a suite of pre-outlined subject matters. Hyperlink context varieties and most important part of web headquartered understanding retrieval assignment. Topical crawlers follow the hyperlinked constitution of the online making use of the supply of understanding to direct themselves towards topically relevant pages. For deriving the proper expertise, they mine the contents of pages which are already fetched to prioritize the fetching of unvisited pages. Topical crawlers depend especially on contextual understanding. This is considering that topical crawlers need to predict the advantage of downloading unvisited pages based on the understanding derived from pages that have been downloaded. One of the vital fashioned predictors is the anchor textual content of the hyperlinks [59]. The area targeted search engines like google and yahoo use these targeted crawlers to download selected

taking you from web page to web page, link after link. The method through which knowledge is

Algorithms are formulas that Google and other search engines use to rank websites and find relevant content to search engine queries. Originally, most websites focused exclusively on optimizing their content and Web copy by including the keywords that people use when searching online for answers, goods or services. However, using this method alone often resulted in literal word matches that didn 't really fit what people wanted to find.

A search engine are used to find out our website when we entering the key words in the search bar, if we use Google as an example if we are searching for something at advertised websites appears at the top of the page. It means these websites have paid Google to let them display their own advertising, having the website on the top of the page it increase the traffic you get on your website.

A URL (Uniform Resource Locator) is defined as human-readable text that is designed to be used in place of IP addresses. Computers use these text-based addresses to communicate with servers. Entering a URL in a web browser is the mechanism for retrieving an identified resource. A URL has many important factors but perhaps the most important factor is its ease of discovery. Visitors on the web have to be able to find a website based on the URL name. All major search engines (Google, Bing, etc.) return search results extracted from millions of web pages based on what the search engine considers to be most relevant to the user. Search results listed on a search engine are ranked based on relevancy. How the content on a website coordinates with a URL is part of that ranking. A search engine optimization (SEO) analyst’s job is to find, attract and engage internet users. To make sure a website is easily discoverable, a URL should be tailored to the content of the website. There are a number of factors that should be considered when creating a URL and they will be discussed in this report.

Search Engine Optimization: Also called as SEO, is the search result displayed search page of any search engine.

The main components include, parallel crawlers/ and crawler control (when and where to crawl), page repository, indexer, analysis, collection of data structures (index tables, structure, utility), and query engine and ranking module. Such a general architecture would take a significant amount of time to code. In this course, we implement stripped down versions of the main

A crawler is a program that retrieves Web pages, commonly for use by a search engine or a Web cache. The World Wide Web commonly known as "WWW ', "Web" or "W3", is a system of Search engine help users to find the documents of their interest with the help of its components called crawler. The basic task of a crawler is to fetch pages, parse them to get more URLs, and then fetch these URLs to get even more URLs. It is basically a program that retrieves and stores pages in a repository. interlinked hypertext documents accessed via the Internet.
