How Search Engines Work with Spider

It is important that you understand how search engines work and exactly how to present information to the person conducting the search and that is how you have raised your website to the attention of potential customers.

In a very simple, as you know is the spider program a robotic system used by the search engine to index web sites. When filling out the submission page to put forward your site to a search engine, the search engine spider to index your site as a whole. The spider visits the website, read the same content, Meta tags and also follow the links on the site to see the other websites where visitors are concerned. After this spider gets all the information you have gathered together and placed in a central repository where it is indexed. Due to the fact that some spiders will only index pages of your site so it is not advisable to create a website with too many pages.

Occasionally the spider to visit the site to see if anything has changed and the moderators of the search engine dictate how this regular review takes place. A spider can index up to a million pages every day is like a book, in which there is a table of contents, followed by the actual and all references and links to other websites found through search. Some examples of search engines are AltaVista, Excite, Google and Lycos.

The search engine locates the requested information by looking through the index compared with the World Wide Web. Since not all search engines use the same algorithm, are search engines produce a variety of results.

The keywords and their frequency and location are one of the things a search engine algorithm looks for in a website, but is also excellent to take the artificial keyword stuffing, also known as spamdexing. The algorithms analyze the way the links to other web pages that allows the search engine to identify what the page is about when the keywords of the linked sites are not different from the original page. 

When you enter a phrase or word, the engine will search its database and return results in an order that is determined by its own algorithm.

So how do they get all that information at the beginning?

Spiders (spiders)

Search engines use spiders use to gather information from websites . Spiders crawl the web sites to collect data and follow the links on the pages. The spiders crawl the Internet almost continuously, collecting new and updated pages of the Web to keep up to date results.

Data Processing

The data extracted spiders are treated differently by the various search engines. Search engines put the 'weight' in different components of a web site and how it fits into the Web . In this way determine the order in which sites should appear in search results (the pages containing the search results are commonly called SERPs - search engine result pages).

Entering

Most search engines update their databases at least once a month with information gathered by their spiders. This is important to know when you have a website relatively new - if you put your web site for the first time in the network at the end of a 'screen' and the spiders will not find it, you'll have to wait until the next update for joining the database. Once the website goes into the database will still take one or two more updates before the new web site is stabilized in the search results.

How Search Engines Work ?

How Search Engines Work ? The automated robots search engines, sometimes called "Spiders" or "crawlers" are seekers of web pages. They work? That is what they actually do? Because they are so important? 

You must think all the fuss about indexing web pages to be added to the databases of search engines, robots are great and very powerful. Error = (. The robots of search engines have only basic functionality as in the beginning was the browsers in terms of what can be understood in a web page. Like early browsers, robots can not do certain things. Robots do not understand frames, Flash movies, images or JavaScript. They can not enter password protected areas or to click on the buttons you have on your website. 

As robots working the search engines? 

Think robots and automated programs for information retrieval, traveling on the web to find information and links. When you have a website to a search engine on the website of "Submit a URL", the new URL is added to the robot's queue of websites to be visited in the next raid. Even if you do not submit directly a page, many robots will find your site because of links to other websites pointing to your site. This is one reason why it is important to increase the link popularity. 

When they arrive at your website, the automated robots first check whether you have a robots.txt file. This file is used to tell the robot which areas of your site are off limits to them. 

Robots collect links from each of the pages they visit and then follow these links to other sites. Thus, they essentially follow the links from one page to another. All World Wide Web is made up of links, the original idea was that you could follow links from one place to another. This makes it move like robots. 

The "headaches" about indexing pages online comes from the designers of search engines who invent different methods to evaluate the information retrieved robots. 

When it is added to the database search engine, information is available for search queries. When a user in a search engine from a query, we made a number of quick calculations to ensure that this engine only valid set of results and thus give the visitors the most relevant answer to your query. 

You can see which pages of your website have been visited by search engine robots looking at server logs or the results of your log statistics program. Having identified the robots, it will show when they visited your site, what pages they visit and how often they visit. Some robots are easily identified by their names user agent (user agent names) as Google's "Googlebot", others are a little darker, like Inktomi "Slurp". 

In addition to identifying individual robots and counting the number of visits, the statistics can also show aggressive bots and you wish not to visit your website. In the resources section at the end of this newsletter, you will find sites that list names and IP addresses robors search engine can help you identify them. 

As you read the pages of your website? 

When a robot visits your site, he studies the visible text of the page, the contents of several labels your page source code (title tag, meta, etc..) And the hyperlinks on your page. The robots use the words and the links to find that this is your page. There are many factors used to find out what interests you. Each robot uses its own algorithm to evaluate and process information. Depending on how prepared the robot in the search engine, information is indexed and then delivered to the database engine. 

The database engine is updated several times. Once you are in the database engine will keep visiting regularly to pick up any changes to your site and ensure they have the latest information. The number of times they visit depends on how you have configured their visits, which may vary for each search engine. 

Sometimes bots can not access the websites they are visiting. If your site is not running or is experiencing a tremendous amount of traffic, the robot may not be able to access your site. When this happens, you do not index it again, this depends on the frequency with which the robot will visit your website. In most cases, robots can not access your site, then try again, hoping that by then your site can be accessed.

What is Search Engine Optimization (SEO)

Search engine optimization (SEO)

In general, users do not make much use of the lists of favorites or bookmarks that provide browsers and systems rarely directly type the URL of the page you want to go, because he might not know it. 

"Doing a good SEO is critical ... but the key is to provide quality content." 

Given this dynamic, web positioning strategies are key. Since other hand, a search after less than 40% of Internet users reached the second page of results provided by a search engine, and only 10% check until the third. This is where it is clear the need to get visibility and get it you need to think like searchers to communicate better with them. 

Google, Yahoo, Bing and company order their results through mathematical algorithms to subject to analysis hundreds of factors. Each company uses a different formula and not the idea to decipher. 

The answer lies in the SEO. SEO is the acronym for "search engine optimization" (Search Engine Optimization) or "search engine optimizer" , which gives us a series of clues and techniques to interpret the way they operate search engines. 

1. Content

What you see vs. users. what search engines see. Users can watch and / or read web pages but search engines can only read the programming code with which they are developed and, even today, still can not read them all equally, for example Flash has recently joined Google results but can not be optimized as HTML. 

Graphics, sound and video are part of a page that search engines can not decipher, for this reason that the positioning work is based on HTML tags and text. 

2. Indexability

This concept refers to the ownership of the page to be properly indexed by search engine robots, allowing them access to every corner, making browsing and showing all its contents clearly. 

"The meta tags 

The Meta Tags are code found in the header and is not visible on the screen when displaying the page. There are several types of Meta-Tags and they do a description of the content and features we want that search engines take into account. 

Meta Robots : This tag is only necessary if you want that page is not indexed in search engines.

Meta Description: This tag is important because it allows us to make a more profound than in the title, which we refer to the page content.

Meta Keywords: Perhaps the most important, she put the key words through the schools want this page to be found on search engines. Any other Meta tag is considered by most search engines, only for some very specialized. It is noteworthy that Meta tags are not a magic solution to position a page in search engines, you need to use all the techniques to get good results.

In conclusion, the main goal HTML tags to keep in mind for a good positioning are: 

- Title. 

Before entering into any other topic or trick of positioning, it is important to define the titles of our pages, which should refer only briefly to the content of the page to which you are assigning, taking care to include the most important word describe the page or section to which we refer. 

- Description. 

Small individual description or abstract of the document as a meta tag that summarizes briefly and concisely the main content of the document that may appear below the title in the "SERP's" (pages of search engine results). 

- H1, H2, H3, Hn ... 

Correspond to the holders of any website, so that the text you include in this tag will be taken into account to know the content of the page. Its importance depends on the number that accompanies them, H1 being the most important and so on up to H6. You should only use one per page level and is not very useful beyond the H4. 

"The relevance 

Relevance is an important point, this means that any word used in the title and meta tags of the page in question should be included within the text content of the page. It is noteworthy that some practices are penalized by search engines such as using hidden text and word lists. 

"The URL 

You must try to be as descriptive as possible and semantically also facilitate the proper indexing of the document. As an example: www.nombreempresa.com / activity-main.html 

To strengthen the content of the site and improve your search engine ranking is important that labels and URL seen before with the same content. 

"The photographs 

They are read by search engines, but you can rename them or give them descriptive attributes to facilitate indexing. A picture of a cat whose name is "12345.jpg" will not be very descriptive, but if you change it to "gato.jpg" will be indicated to the search engines what that picture is. You can also add the ALT attribute very important for accessibility of documents and for proper indexing, with a description of the photo, in this case ALT = "a gray cat," and that will also serve people with disabilities visual acquainted with them. 

"The outgoing links 

They are also an important factor in the confidence that generates a site. Always try to add value to the user through the content with outbound links. Since your users can not navigate all the available web pages, your site becomes a benchmark with unique content and a number of resources that extend and complement the information. 

"The map 

Finally, your site should include a file sitemap.xml , a map of your site to facilitate proper indexing by search engines. 

3. Keywords

One of the most crucial factors in the management of the natural results are the key words, as in any book we are informed of the contents of the page to be text, are perfectly understood by search engines, you should avoid using text as: "Home Page", "Home," Name of the Institution. "Search engines are the main gateway to cyberspace. A person who wants to find a page on the Internet, usually done through a search engine. 

All positioning campaign must begin with the analysis of keywords or keywords for which you want to optimize the website. Keywords are defined as those words like "hotel" or strings of words such as "hotels in Barcelona" and your choice will depend on the content of your campaign objectives and finally, the target or target you want to go .

Keywords (keywords). The basis of all search engine ranking are the key words, for according to the words that we include on our site, we store the search engines. So choose the best keywords for the site is one of the great challenges of SEO. The typical procedure to select and find keywords is that once chosen the theme on which we write, we do an investigation of possible keywords; through research on the topic to see what kind of concepts and words are the that are more related to it and then brainstorm ideas related words (can be through a tool like Google for keywords ). Once you've identified several key words then check the frequency with which they are searched and choose according to your target market and the competition for that keyword. It should be noted that the term "keyword" does not necessarily refer to a word and in most cases refers to sentences. 

Optimisation. Once you have the list of keywords that are going to use you should try to make the best use optimizing your content via tags , as the title (title), headings (h1, h2, h3, ...) and the description (mini-summary of your page). 

Authority. The way you show the search engines that our site is relevant, is through the sites we link. Do other sites link to us is what is known as link building . In addition, since the content is not sold alone is important to promote related sites, portals and social networks and eventually cultivate relationships with other bloggers and your own readers as it is they who can help you promote you by word of mouth.
