Even if you tend to speak broadly of the "engines", you can actually distinguish between 2 different systems for Web search:

Directory

Can be defined as catalogs of sites: the human personality, on the basis of external reporting, select sites and classifies them according to a classification tipo.L 'inclusion in the category can be either a fee or free. Typically, to increase their databases, directories use as a second source engines which bind agreements: hence the inclusion in some directories may be important to improve the positioning engine that reference (for example, Dmoz be helping the ranking on Google). Popular directories are Yahoo, Virgilio, Arianna, Dmoz.

Motors

Can be defined as a database of pages of sites. On some engines you can apply to have the sites, in most cases, this integration is due to the passage of a crawler that scours the web following the chain of links starting from the pages already in the database. Therefore, the work of an engine is divided into 3 phases:

Analysis of the Web through the use of spiders (or robots or crawlers). It 'important to know that spiders can be treated as a browser by reading ability is very limited compared to modern ones: therefore, an engine not read all the graphic portions of a site, Flash animation (even if you are carrying out experiments in this regard), the JavaScript code, the parties in ASP or PHP.

Cataloging the pages obtained in a manner which may vary from one engine to another.

Response to user requests. To provide a response to a request, the engine must be able to assess the relevance of pages than requested: extrapolated from the database files that contain the keyword entered by the user, it is established relevance through proprietary algorithms that are increasingly refined over time . Ultimately the results are given in the SERP (Search Engine Result Pages and pages of search engine results). Among the best known search engines and Google is certainly used. Search engines are used most Italians Free and Virgil, however, merely repeat the results of Google.

How and why to be found in Engines

The Web now represents a vast reservoir of information and statistics confirm that users rely primarily on search engines to navigate and locate pages of interest. From this simple consideration shows how important it is to appear in search engine results (SERP) for keywords identified. Realistically, getting a good ranking on this page requires a significant long-term strategy, more or less detailed and complex in relation to what you are willing to invest and the objectives they want ottenere.Le choices and activities that contribute to making and maintaining visible site on a motor are numerous and varied but among these one should look at:

The choice of keys

For "key" is the word or group of words that the Navigator as part of search string on search engines. To select the keys to work can proceed as follows:
Apply a first list of keys that appear to be related to the topics covered in the site. A good tip is to stretch the list to try to imagine what words users might use to search the site in question, another strategy is to try to identify which keys are optimized for the sites of direct competitors.
Analysis on the statistics provided by some search engines to identify and prioritize key most wanted, and thus can generate more traffic.

Use Google suggestions tool to expand the list with keys attached.

Optimization

Optimization refers to activities undertaken to ensure that the pages of a site will appeal to search engines and, consequently, are firmly positioned on specific chiavi.Innanzi everything you need to order the keys identified in order to obtain a pyramid with the key incima More importantly, the second level a group of 2 or 3 keys slightly less important, and so to descend to the base with all the remaining keys and somehow connected. Each page of the site will be optimized for one keyword, the most important and should be slightly optimized for keys on the second level of the pyramid. Considering the whole site is important that there are many pages optimized for the key to the first level and fewer pages optimized to get the keys to the second level as the main keys. At this point you must use the keys to the composition of tags, meta tags and content.

Tags <Title>

Represents a major element for positioning on a page: for example, when performing a search, Google looks at first the contents of the tag <Title> trying to compare its contents with those words in the text and links pagina.Dunque of a good Title should:

• consist of 2 / 4 words and not exceed, however, 60 characters;
• contain the most important key without being exactly equal to the key;
• be consistent with the page and not be the same throughout the site.

Meta Tags <Description>

In many cases, appears along with the Title on the results page (SERP) and statistics show that clicks on the first positions are influenced by their description and how this is able to attract your attention, in relation to its interests. Good Description must:

• be composed of a meaningful sentence, contain the most important key and some second level;
• be consistent with the page and not be the same throughout the site;
• be able to attract attention and give relevant information.

ALT attribute
The ALT attribute TAG <IMG> need to provide alternative text that can be used in all situations where the element <IMG> same can not be displayed, for example, due to improper loading, or because you are browsing through text-based browsers or screen reader.Mentre images are not taken into account by the engines, the alternative text associated with them are considered to all effects as integral parts of the text.
For the purposes of web site, the alternative text should not be a simple description of the image but have the same function that the image has in the context of pagina.Ai optimization purposes, the ALT attribute must:

• be composed of a meaningful sentence;
• have the same issue of page;
• must all be different;
• if possible, should be relevant to the image and the image file name;
• at least one page, must contain the main key, most of the main keys should be put to a halt.

Attribute Title

The title attribute of tag <A> need to provide a text that is displayed in the tooltip that appears when you hover your mouse over the link. The purpose of this note is to make clear to you what happens by activating the link: opens a new window is proposed. PDF file, ecc.Ai purpose of optimizing the site, the title attribute of links should:
be composed of a meaningful sentence; be relevant to the page pointed to by links;
if possible, must have the same theme of the page, must all be different;
at least one page, must contain the main key;
most of the main keys should have a title attribute that contains.

Meta Tags <keywords>
Originally important as the abuse that has been made, is not so regarded by Motori.Un good Meta Tags <keywords> should:

• hold the master key of the page;
• contain some of keys of the second level;
• contain only words in the visible text of the page or in the ALT images;
• be three or four key phrases at most, separated by commas.

Pictures
The images help to define the topic of a page and in any case, may be themselves the result of a ricerca.Per images should:

• choose a name that relates both to the image of the page;
• if possible, should contain the name of the master key;
• each image should be named differently and contain different keys;
• follow as indicated above for the clause ALT,
• insert the image into a text that treats the same subject;

Out-bound links

We define link out-bound links from that page of a site link to pages on other sites: are very important for placement since that increase the relevancy of a topic.

And 'likely, in fact, that the links between pages bind themselves in relation to allowing surfers to extend their research

• in a pertinente.Nel create out-bound links you should follow these general rules:
• each page should contain a pair of outbound links from the site, up to 5 or 6;
• pages should link to the theme;
• links must have an alternative text themed episode page and, if possible, with that from which the link;
• group of outgoing links, at least one should contain the main key of the page;
• the title of the link must be themed episode page and, if possible, with the start page;
• links should be monitored regularly, to remove those that link to pages that no longer exist;
• if possible, should be some link in the page text, in part related to it;
• bet never penalized sites or spam-engine.

The texts

Only the pages are the most important factor in relation to placement. Each page should cover one topic in order to increase relevance to the topic. The text of the page must clearly be significant, including the size, consisting of at least 250 words, but better still 400 or 500 words. Keys identified should be included within the text but must pay attention to their number of repetitions (key density): keys to a single word should have a density of 10%, two key words, instead of around 15 - 20%. It 'important that especially the most important key to have a good number of repetitions but it is equally important not to exceed in repeating the same key (key stuffing). The site, overall, there must be a number of pages devoted to the most important key than those devoted to less important keys.
