Crawler Parental Control issues?

I just got today Crawler Parental Control, and after it is installed, started giving me problems. The form that set the options in "Manage Accounts" Change Settings "Enable Internet navigation" Limits of contents page disabled by default websites blocked off, do not put anything in trusted Web sites, and put a site on the users blocked websites. I learned in order to work, you must configure the proxy. So I followed the instructions. I have Mozilla Firefox version 3.0.13, and said crawler for version 1.5.0.1 of Firefox go to connection settings and check the manual configuration of proxy and http proxy to localhost, and put the port 3128. So when I try to load any page that just show a blank page. And when I go on that site blocked it is blocked. Please help me. If you did not know what the problem, please put a parental control program that is free to download and requires no subscription and requires a password. And please, no Add-ons.

This is very popular and free to use. Http: / / www1.k9webprotection.com /

Anatomy of a search engine and trackers Khonz.com

When you go to a search engine and perform a search that many people do not understand how results end there. Some people may think that the sites are submitted while others know that a piece of software finds the pages. This article explains a piece of that puzzle: The search engine crawler.

Today, search engines are based on packages of software called spiders or robots. These automated tools are used to search the web to discover new pages.

A brief history of search crawlers "The first crawler was Wander World Wide Web and appeared in 1993. It was developed by MIT and its primary purpose was to measure the growth of the web. Soon after, however, produced an index from the results – in fact the first "search engine."

Since then, the trackers have evolved and developed. At first they were simple creatures crawlers only specific bits can index web page data, such as meta tags ( Khonz.com do not believe in target search). Soon, however, search engines realized that a truly effective crawler must be able to index other information, including visible text, alt tags, images and even other non-HTML content such as PDF documents word processing and more.

How does a Crawler – In general, the crawler gets a list of URLs to visit and shop. The scanner does not rank the pages, only comes out copies stored or transmitted to the engine Search for later index and rank according to various aspects. However, to accelerate the process of some caterpillars is associated with indexer. So when tracking Indexing is also (as a tracer of Khonz.com )

search crawls are also sufficiently smart to follow the links on pages. It is possible that these links as they find them, or were saved and later visit. While Only the search Khonz.com Bangladesh website so you do not follow the link to new domain, just simply follow the link same domain.

To date, literally dozens of crawlers regularly indexing the web. Some are specialized crawlers – such as image indexers, while others are more general and therefore more well known.

Some of the most popular trackers including Googlebot (Google) MSNBot (MSN), Slurp (Yahoo!) And RoyCrawler (From Khonz.com). There is also the Teoma crawler (Ask Jeeves), as well as an assortment of other engines crawlers, such as shopping engines, blog search engines and more.

Generally, when a crawler comes to visit a site, requesting a file called "robots.txt". This file tells the crawler Search the archives that can be ordered, and what files or directories is not allowed to visit.

The file can also be used to limit access spiders specific to any or all of the site, and also can be used to control how many times the crawler visits the site, by limiting its speed or times when the crawler can visit. (Yahoo! S Slurp and MSNBot support the "Crawl Delay" directive which tells crawlers decrease in tracking).

It is imperative that the site has a robots.txt file as a crawler but assume it is okay to index the site if there is no such file.

Another thing you can noted, as the reports sees your web server log, is that some browsers are Many Different times and in different configurations.

Yahoo! Slurp s, example emulates many different hardware platforms – from Windows 98 to Windows XP, and many different browsers, from Internet Explorer to Mozilla. RoyCrawler of Khonz.com also works and – emulating different operating systems and browsers, but only support Unicode font is not based on any embedded font.

They do this to ensure support – after all, search engines want to be sure that most of its users to find a site that can be used. Therefore, as a design tip, you should test your site against hardware platforms and browsers as well. You do not have to use the variety that search engines use, but must be tested against Internet Explorer, Netscape and Firefox. In addition, you should try your site on other platforms like Mac or Linux just to ensure compatibility.

You may also notice when reviewing their reports, that crawlers like Googlebot will visit several times and ask the same page (s) repeatedly. This is common crawlers that also want to be sure the site is stable and also to measure the frequency of page change.

If their site goes down temporarily when a crawler visits repeatedly like this, do not worry. The crawlers are smart enough to leave and come back later and try again. However, if they continue to find the site down, or slow to respond, they may choose to stay outside for longer periods, or index the site more slowly. This can negatively impact the performance of your site in search engines. RoyCrawler (of Khonz.com) remove a page if the page can not be accessed by the end of a month.

As time passes, it is expected that these spiders to be even more advanced. Because the new authoring technology is available, or new options Indexing is available, the search crawlers will be adapted. Remember, the goal of all search engines is to have the most complete index of files found on the web. This means they want to be able to index more than web pages.

Just as you are designing your site, make sure to keep crawlers in mind. Do not build your website for crawlers – build for users – but be sure to test it thoroughly to allow crawlers to see what they want without obstacles and roadblocks. Remember – the crawler is the best friend of the owner of the site.
