This allows search engines to keep track of how many external pages link to each page. Usually, the more incoming links a page has, the higher it will be ranked in search engine results.

Commonly spider webs' geometry is oriented perpendicular to the plane of the net—prey bearing impact occurs in the capture spiral portion of the web. The spiral strands are better impedance-matched to the radial strands in the out-of-plane direction and transmit more energy to them in these modes [17].Feb 14, 2021

Spider orb webs are multifunctional structures, the main function of which is to dissipate the kinetic energy of the impacting prey, while minimizing structural damage. There is no single explanation for their remarkable strength and ductility.Aug 10, 2016

Instead of boards, spiders produce silk threads to build their webs. The silk is produced in silk glands with the help of the spider's spinnerets. ... When a spider begins a web, it releases a silk thread. It anchors the thread to some object — a branch, a corner of a room, a doorframe — wherever it builds its web.

The orb weaver spiderweb is crafted in a way that not only allows it to capture prey but also to maintain structural integrity. The web must withstand the pressure of insect landings and the strain from escapes.Sep 1, 2021

A "software spider" is an unmanned program operated by a search engine that surfs the Web just like you would. ... The software spider often reads and then indexes the entire text of each Web site it visits into the main database of the search engine it is working for.Apr 24, 2000

The spider name dates back to the 1800s, when a horse-drawn carriage was the main mode of transportation. ... There were cargo-bearing carriages, people-movers, and lightweight, less cumbersome carriages which, thanks to their looks, came to be known as spiders.May 14, 2018

The anatomy of spiders includes many characteristics shared with other arachnids. These characteristics include bodies divided into two tagmata (sections or segments), eight jointed legs, no wings or antennae, the presence of chelicerae and pedipalps, simple eyes, and an exoskeleton, which is periodically shed.
