Web Promotion
If you have a web site you will no doubt want people to be able to find it. Your web site is your shop window for the rest of the world. Ask yourself the following:- do you want your shop in a prime position? looked at by thousands? can you afford not to? Search engine optimisation is what you need in order to get anywhere online.Search Engine Optimisation
Search Engine Optimisation is something of a black art in the internet industry but put simply it is the practice of adjusting the web pages so as to make it Search Engine Friendly.
What is a web spider and how does it work to place my site in search engines?
The explanation from Wikipedia, the online encyclopedia (extract below), clarifies some points but does show the difficulties faced when you optimise your web pages for search engines.
If you manage to reach the end of the article, you will appreciate the problems you will have to deal with when you enter the realms of search engines, optimisation and marketing. (Also bear in mind that this the extracted version of the entry - there are another 800 words which explain how these systems work).
SEO (search engine optimisation) and SEM (search engine marketing) are very specialised areas and, unless you have a lot of time to spare, probably best left to specialists in the field.
A web spider is a program which browses the World Wide Web in a methodical, automated manner. Spiders are mainly used to create a copy of all the visited pages for later processing by a search engine, that will index the downloaded pages to provide fast searches. (also known as a web spider or web robot) is a program which browses the World Wide Web in a methodical, automated manner. Other less frequently used names for web crawlers are ants, automatic indexers, bots, and worms (Kobayashi and Takeda, 2000).
In general, it starts with a list of URL's to visit. As it visits these URL's, it identifies all the hyperlinks in the page and adds them to the list of URL's to visit, recursively browsing the Web according to a set of policies.
There are two important characteristics of the Web that generate a scenario in which web crawling is very difficult: its large volume and its rate of change, as there is a huge amount of pages being added, changed and removed every day. Also, network speed has improved less than current processing speeds and storage capacities.
The large volume implies that the crawler can only download a fraction of the web pages within a given time, so it needs to prioritise its downloads. The high rate of change implies that by the time the crawler is downloading the last pages from a site, it is very likely that new pages have been added to the site, or that pages have already been updated or even deleted.
Given the current size of the Web, even large search engines cover only a portion of the publicly available content; a study by Lawrence and Giles in 2000 showed that no search engine indexes more than 16% of the Web. As a crawler always downloads just a fraction of the web pages, it is highly desirable that the downloaded fraction contains the most relevant pages, and not just a random sample of the web.
This requires a metric of importance for prioritising web pages. The importance of a page is a function of its intrinsic quality, its popularity in terms of links or visits, and even of its URL (the latter is the case of vertical search engines restricted to a single top-level domain, or search engines restricted to a fixed web site).
Designing a good selection policy has an added difficulty: it must work with partial information, as the complete set of web pages is not known during crawling. The ordering metrics tested were breadth-first, back link-count and partial Page rank calculations. One of the conclusions was that if the crawler wants to download pages with high Page rank early during the crawling process, then the partial Page rank strategy is the better, followed by breadth-first and back link-count.
However, these results are for just a single domain. Focused crawling: The importance of a page for a crawler can also be expressed as a function of the similarity of a page to a given query. They also noted that the problem of web crawling can be modeled as a multiple-queue, single-server polling system, on which the web crawler is the server and the web sites are the queues. Page modifications are the arrival of the customers, and switch-over times are the interval between page accesses to a single web site. The explanation for this result comes from the fact that, when a page changes too often, the crawler will waste time by trying to re-crawl it too fast and still will not be able to keep its copy of the page fresh.
Explicit formulas for the re-visit policy are not attainable in general, but they are obtained numerically, as they depend on the distribution of page changes. Web crawlers are a central part of search engines, and details on their algorithms and architecture are kept as business secrets. When crawler designs are published, there is often an important lack of detail that prevents others from reproducing the work.
There are also emerging concerns about "search engine spamming", which prevent major search engines from publishing their ranking algorithms.
