2. Basics

2.1. Search Engines
Before we start talking about search engine optimization need to understand how search engines work. Basically, each form consists of 3 parts:

    The crawler (or spider). This part of the search engine is a simple robot that downloads web pages in a site and crawl looking for links. Then, open and download each one of these links to track them too. The crawler visits the web site periodically to find changes in the content and modify their ranking according to these. Depending on the quality of a web site and frequency of content updates that may occur from say once a month to several times a day for news sites high popularity.

    The crawler does not rank web sites himself. Instead, it simply passes all websites tracked to another search engine module called the indexer.

    The indexing. This module stores all the pages crawled by the spider in a large database called the index. Think of it as the index of a book, find a word and see what pages they mention it. The index is not static, it is updated each time the crawler finds a new page or back a track already in the index. Since the volume of the index is very large, it is common to take time to make any changes to the database. So we can say that a website has been traced, but has not yet been indexed.

    Once the web site with all its content has been added to the index, the third part of the browser begins to work.

    The creator of rankings (or the browser software). This part interacts with the user and waits for a consultation. Then check millions of pages indexed and is all relevant to that query. The result is sorted by relevance and finally displayed to the user.

    What is relevant and how it can determine whether a page is more or less relevant to a query? Here comes the tricky part: the ranking factors ...

2.2. Terminology
Here are the basic terms you need to know. All others will be explained by the wayside.

Anchor Text
This is simply the text of a link. Suppose you have a link like this:

<a href="seo-faq-tutorial.htm"> The Basics of SEO - a complete guide <a>
The link would look like:
The basics of SEO - A Complete Guide

The text "Fundamentals of SEO - A Complete Guide" is in this case the "anchor text." Anchor text is the key parameter in a link building strategy. Always make sure that the anchor text of a consistent link to the topic of this page. If your site is about dogs, not an anchor text link that says "Cats." Obviously can not control each and every one of the links on the web, but at least it should make all the links from your own site with proper anchor text.

Incoming Link
... Or external link is a link That points to your site. is a link pointing to your site. The more you have, the better. But in particular there are many exceptions to this rule, so read the external optimization section page for details.

Keyword
One or more words that describe the topic of a website or page. In fact, we should distinguish between keywords and key phrases, but in practice all called SEO keywords. For example, the keywords on this page: FAQ SEO, SEO tutorial, etc.

Long and short Keywords
This is easy. The keywords are words and short phrases and common general as "rent a car", "seo", "buy a toy," "personal loan" and others. The long, however, describe an item accurately, "bmw lease new york", "seo florida, buying a teddy bear", etc. The more precise a keyword, less popular, fewer people writes this exact query into the search box. But the other side of the coin is, as each query is fairly straightforward, once a visitor arrives at your site from a query into a search engine and see what you're looking for, is very likely that visitors will soon become a client. This part is very important! long queries are not very popular, but the rate of conversion of such queries is much higher than for short ones.

SERPs
You may have heard this term, but did not understand what it was. SERP means "Search Engine Result Page (Search Engine Results Page). If a user types a query and press Enter you will be redirected to the SERP. Then you can click one of the results to open that website. Obviously, the results shown at the top get a lot more visitors than on pages 2, 3 or below. This is the real purpose of SEO: make a web site development in the SERP.

Snippet
This is a short description displayed by a search engine SERP listing. The snippet is usually taken from a Meta Description tag, or can be created automatically by a search engine based on the contents of a page.

Landing Page
The landing page is a page open when a visitor arrives at the site by clicking on a SERP. Here's a sample query:

Free Monitor for Google


In this case, the page www.cleverstat.com / en / google-monitor-query.htm is a landing page for the query "google monitor. "

Link juice
This funny term indicates the value that goes from page to page through a link between them. To be precise: the linked page (acceptor) gets a link juice from the binding site (donor). The more link juice flowing to a page, the higher will be in the ranking. Imagine a page that is worth 10 dollars, this would be the value of that page. If a page has 2 links, then each one costs $ 5, and that is the amount of link juice going to the linked page. If the first page has 5 links, each one spends $ 2 then only the initial link juice. Here's a simple example to illustrate this concept:

 Link juice explanation. $5 value links.
Each link passes a value of $ 5




Link juice explanation. $2 value links.

Each link passes a value of only $ 2

This means that the more links the page to have less value B wins every page linked from the page A. Obviously, the real value of the link juice is not measured in dollars.

Nofollow Links
The nofollow link is a link that search engines should not continue. To make a nofollow link needs the following code:

<a href="somepage.html" rel="nofollow"> Any text anchor </ a>

Google does not follow nofollow links and no link juice passed through those links. You can read more about nofollow links here.

Link Popularity
This term designates the amount of incoming links pointing to a site. Popular sites are more links. However, the number of incoming links is only half the issue. Read the section on external optimization page below to learn more.

Keywords Abuse
When you put a long list of keywords on a label, that is abuse of keywords. For example, a title tag for this page might be: <TITLE> SEO guide, FAQs, SEO, SEO tutorial, faq best seo, seo techniques, seo strategy guide </ TITLE>, etc. This would be the abuse of keywords. Instead, the current title of this page (the one you are reading now) is quite natural and adequately describes its contents. Do not use keywords abuse because a) does not work, b) is a bad practice that can affect your rankings.

Robots.txt
Robots.txt is a file that aims to tell the search engine spiders when they crawl or not to allow the site's content. It is a simple txt file in the root folder of your website. Here are some examples:

It blocks the entire site for GoogleBot:
User-agent: Googlebot
Disallow: /

It blocks all files in a folder except for all crawlers myfile.html:
User-agent: *
Disallow: / folder1 /
Allow: / folder1/myfile.html
