Google is a web powerhouse and has been synonymous with information retrieval. Jonathon Fletcher, twenty years ago, invented the first search engine that crawls the internet. This web giant would not be the same place it is today. Fletcher's invention, which was developed at the University of Stirling in Scotland is still used by many of the most popular search engines. But how did it get there? What should you know?
Objectives
Crawling a website's content is done to find links and relevant content. Search engine algorithms are programmed to collect billions of links and then sort them in seconds. They aim to deliver high-quality search results that meet a user's query. After crawling a website they analyze its content and code in order to determine if it's indexable. This information is used by indexers to rank pages and show content in search results.
Uniform policy
The content on a website can affect the best revisiting policy. For example, a proportional policy ignores pages that are frequently updated, while a uniform policy increases access frequency as the rate of change increases. A uniform policy favors freshness and a re-visiting strategy is more similar. A search engine should visit a webpage as often and as frequently as possible. It should also penalize pages that are too frequent.
Proportion
Google's percentage in crawling websites varies. While major search engines typically cover a substantial part of the public internet, this number may be misleading. One study showed that Google, Yahoo, and MSN index only 40 to 70 percent of the web. However, only 16% of the web was indexed by search engines in 1999. While crawlers do download some pages, they want to pick the best ones for indexing purposes.
Request rate limitation
Many third party platforms have limits on the amount of pages a crawler can call. This is done to stop crawlers from calling too many pages in a short time. The server can crash if the crawler keeps calling pages at high rates. A good solution is to create a crawl schedule that limits the number of requests from a specific IP address. A crawl schedule to limit the requests from a certain IP address is a good idea. But there are other factors.
Different types of focused crawlers
A focused crawler algorithm is one that uses a topic taxonomy to determine the topic. It makes efficient use of reinforcement learning to crawl a markup language. Human users are required to provide example URLs related to a topic. Once the user has given an example URL, the focused crawler routes the current webpage to the most relevant nodes. The user can also mark any nodes along the route. These nodes are then highlighted in the tree view.
Methods
Crawlers use links to navigate between pages. These links may have the nofollow attribute set, which tells search engines to ignore the link. Although crawlers can still follow the links on the page, nofollow links won't pass any link juice onto the destination page. This will not affect any links on the page but could impact the search engine’s indexing. In such a situation, a webmaster should implement a nofollow attribute to prevent crawlers from following links.

Creative writing requires that you know how to set yourself apart from the rest.
Most writers are similar. Writing follows the same patterns. They fall back to cliches and repeat themselves.
Breaking out of the patterns is key to developing new ideas. It's about thinking outside the box.
You must also find interesting ways to make you writing more engaging. You must think about what motivates your audience when writing for them. What turns them on? What makes them giggle? What makes them weep?
