What is URL Redirect ? How You can Earn using redirect URL'S ?

URL redirection, also called URL forwarding, is a World Wide Web technique for making a web page available under more than one URL address. When a web browser attempts to open a URL that has been redirected, a page with a different URL is opened. Similarly, domain redirection or domain forwarding is when all pages in a URL domain are redirected to a different domain, as when wikipedia.com and wikipedia.net are automatically redirected to wikipedia.org.



URL redirection is accomplished for different reasons: 

For URL shortening; 

To forestall broken connections when website pages are moved; 

To permit various space names having a place with a similar proprietor to allude to a solitary site; 

To direct route into and out of a site; 

For security assurance; and 

For unfriendly purposes, for example, phishing assaults or malware appropriation. 

Comparative area names 

A client may mistype a URL, for instance, "example.com" and "exmaple.com". Associations regularly register these "incorrectly spelled" areas and divert them to the "right" area: example.com. The addresses example.com and example.net could both divert to a solitary area, or site page, for example, example.org. This strategy is frequently used to "save" other high level spaces (TLD) with a similar name, or make it simpler for a valid ".edu" or ".net" to divert to a progressively conspicuous ".com" area. 

Moving pages to another area 

Site pages might be diverted to another area for three reasons: 

a site may want, or need, to change its space name; 

a creator may move their individual pages to another area; 

two sites may consolidate. 

With URL diverts, approaching connects to an obsolete URL can be sent to the right area. These connections may be from different locales that have not understood that there is a change or from bookmarks/top choices that clients have spared in their programs. The equivalent applies to web search tools. They regularly have the more established/obsolete space names and connections in their database and will send search clients to these old URLs. By utilizing a "moved for all time" divert to the new URL, guests will in any case end up at the right page. Additionally, in the following web search tool pass, the web index ought to recognize and utilize the more current URL. 

Logging active connections 

The entrance logs of most web servers keep itemized data about where guests originated from and how they perused the facilitated webpage. They don't, be that as it may, log which joins guests left by. This is on the grounds that the guest's program has no compelling reason to speak with the first server when the guest taps on an active connection. This data can be caught in a few different ways. One way includes URL redirection. Rather than sending the guest directly to the next webpage, joins on the website can direct to a URL on the first site's area that consequently diverts to the genuine objective. This procedure bears the drawback of the postponement brought about by the extra solicitation to the first site's server. As this additional solicitation will leave a follow in the server log, uncovering precisely which connection was followed, it can likewise be a protection issue.[1] a similar procedure is additionally utilized by some corporate sites to actualize an explanation that the ensuing substance is at another site, and hence not really associated with the enterprise. In such situations, showing the admonition causes an extra deferral.

Post/Redirect/Get

Post/Redirect/Get (PRG) is a web advancement configuration design that forestalls some copy structure entries if the client taps the revive button in the wake of presenting the structure, making an increasingly natural interface for client specialists (clients). 

Gadget focusing on and geotargeting 

Sidetracks can be viably utilized for focusing on purposes like geotargeting. Gadget focusing on has gotten progressively significant with the ascent of versatile customers. There are two ways to deal with serve versatile clients: Make the site responsive or divert to a portable site rendition. On the off chance that a versatile site variant is offered, clients with portable customers will be naturally sent to the relating versatile substance. For gadget focusing on, customer side sidetracks or non-cacheable server-side sidetracks are utilized. Geotargeting is the way to deal with offer restricted substance and naturally forward the client to a confined variant of the mentioned URL. This is useful for sites that intended interest group in more than one area or potentially language. Normally server-side sidetracks are utilized for Geotargeting yet customer side sidetracks may be a choice too, contingent upon requirements.[2] 

Controlling web crawlers 

Sidetracks have been utilized to control web crawlers with deceptive expectations, e.g., URL seizing. The objective of deceiving diverts is to drive search traffic to presentation pages, which need more positioning force all alone or which are just remotely or not in the least identified with the hunt target. The methodology requires a position for a scope of search terms with various URLs that would use slippery sidetracks to advance the searcher to the objective page. This strategy had a recovery with the uprise of cell phones and gadget focusing on. URL seizing is an off-area divert technique[3] that misused the idea of the web crawler's dealing with for transitory sidetracks. On the off chance that a brief divert is experienced, web crawlers need to choose whether they allot the positioning an incentive to the URL that introduces the divert or to the divert target URL. The URL that starts the divert might be kept to appear in list items, as the divert shows an impermanent nature. In specific situations it was conceivable to abuse this conduct by applying brief sidetracks to well-positioning URLs, prompting a substitution of the first URL in query items by the URL that introduced the divert, in this manner "taking" the positioning. This technique was generally joined with slippery sidetracks to re-focus on the client stream from the indexed lists to an objective page. Web search tools have created proficient advancements to identify these sorts of manipulative methodologies. Significant web indexes typically apply unforgiving positioning punishments on locales that get discovered applying strategies like these.[4] 

Controlling guests 

URL redirection is some of the time utilized as a piece of phishing assaults that confound guests about which site they are visiting.[5] Because current programs consistently show the genuine URL in the location bar, the danger is reduced. In any case, sidetracks can likewise take you to destinations that will in any case endeavor to assault in different manners. For instance, a divert may take a client to a website that would endeavor to fool them into downloading antivirus programming and introducing a Trojan or some likeness thereof. 

Evacuating referrer data 

At the point when a connection is clicked, the program sends along in the HTTP demand a field called referer which shows the wellspring of the connection. This field is populated with the URL of the current website page, and will wind up in the logs of the server serving the outer connection. Since touchy pages may have delicate URLs (for instance, http://company.com/plans-for-the-following arrival of-our-item), it isn't attractive for the referrer URL to leave the association. A redirection page that performs referrer covering up could be installed in every outer Url, changing for instance http://externalsite.com/page into http://redirect.company.com/http://externalsite.com/page. This strategy likewise disposes of other possibly delicate data from the referrer URL, for example, the meeting ID, and can lessen the opportunity of phishing by showing to the end client that they passed a reasonable door to another site.
