This article will be primarily useful for novice optimizers, because more advanced and so should know everything about them. In order to use this article with maximum efficiency, it is advisable to know exactly which words need to be raised to the right positions. If you're not exactly sure about the word list yet, or use the keyword suggestion service, it's a little confusing, but you can figure it out.

Important! Rest assured, Google understands perfectly well that ordinary users will not use them and only promotion specialists resort to their help. Therefore, Google may slightly distort the information provided.

Intitle operator:

Usage: intitle: word
Example: intitle: website promotion
Description: When using this operator, you will receive a list of pages, the title of which contains the word you are interested in, in our case it is the whole phrase "site promotion". Note that there must be no space after the colon. The title of the page is important for ranking, so be responsible for writing your titles. Using this variable, you will be able to estimate the approximate number of competitors who also want to be in the leading positions for this word.

Inurl operator:

Usage: inurl: phrase
Example: inurl: calculating the cost of search engine optimization
Description: This command shows sites or pages that have the original keyword in their URL. Note that there must be no space after the colon.

Inanchor operator:

Usage: inanchor: phrase
Example: inanchor: seo books
Description: Using this operator will help you see pages that are linked with the keyword you are using. This is a very important team, but unfortunately search engines are reluctant to share this information with SEOs for obvious reasons. There are services, Linkscape and Majestic SEO, that are willing to provide you with this information for a fee, but rest assured, the information is worth it.

Also, it is worth remembering that now Google pays more and more attention to the "trust" of the site and less and less link mass. Of course, links are still one of the most important factors, but trust plays an increasingly important role.

Good results are obtained by a combination of two variables, for example intitle: promotion inanchor: site promotion. And what we see, the search engine will show us the main competitors, the title of the page of which contains the word "promotion" and incoming links with the anchor "site promotion".

Unfortunately, this combination does not allow you to find out the "trust" of the domain, which, as we have already said, is very important factor... For example, a lot of old corporate sites don't have as many links as their younger competitors, but they do have a lot of old links that pull these sites to the top of the SERPs.

Site operator:

Usage: site: site address
Example: site: www.aweb.com.ua
Description: With this command, you can see a list of pages that are indexed by the search engine and which it knows about. It is mainly used to find out about competitors' pages and analyze them.

Cache operator:

Usage: cache: page address
Example: cache: www.aweb.com.ua
Description: This command shows a "snapshot" of the page from the moment when the robot visited the site the last time and, in general, how it sees the content of the page. By checking the page cache date, you can determine how often the robots visit the site. The more authoritative the site, the more often robots visit it and, accordingly, the less authoritative (according to Google) site, the less often the robots take pictures of the page.

The cache is very important when buying links. The closer the page's caching date is to the link purchase date, the faster your link will be indexed by the Google search engine. Sometimes it was possible to find pages with a cache age of 3 months. By purchasing a link on such a site, you will only waste your funds, because it is quite possible that the link will never be indexed.

Link operator:

Usage: link: url
Example: link: www.aweb.com.ua
Description: Link operator: searches and displays pages that link to specified address url. This can be both the home page of the site and the internal one.

Related operator:

Usage: related: url
Example: related: www.aweb.com.ua
Description: The related: statement displays pages that the search engine thinks are similar to the specified page. For a person, all the resulting pages may not have anything similar, but for a search engine it is.

Info statement:

Usage: info: url
Example: info: www.aweb.com.ua
Description: By using this operator, we will be able to obtain information about the page that is known to the search engine. This could be the author, publication date, and more. Additionally, on the search page, Google offers several actions at once that it can do with this page. Or, more simply, he will suggest using some of the operators that we described above.

Allintitle operator:

Usage: allintitle: phrase
Example: allintitle: aweb promotion
Description: If we start our search query with this word, we get a list of pages that have the entire phrase in the title. For example, if we try to search for the word allintitle: aweb promotion, we will get a list of pages, in the title of which both of these words are mentioned. And they do not have to follow each other at all, they can be located in different places in the header.

Allintext operator:

Usage: allintext: word
Example: allintext: optimization
Description: This operator searches for all pages that contain the specified word in the body of their text. If we try to use allintext: aweb optimization, we will see a list of pages in the text of which these words are found. That is, not the whole phrase is "optimization aweb", but both words and "optimization" and "aweb".

Any search for vulnerabilities on web resources begins with intelligence and information gathering.
Intelligence can be either active - brute-force files and directories of the site, launching vulnerability scanners, manual browsing of the site, and passive - searching for information in different search engines. Sometimes it happens that a vulnerability becomes known even before the first page of the site opens.

How is this possible?
Search robots, non-stop wandering the Internet, in addition to information useful to an ordinary user, often record what can be used by cybercriminals in an attack on a web resource. For example, script errors and files with sensitive information (from configuration files and logs to files with authentication data and database backups).
From the point of view of a search robot, an error message about an sql query execution is plain text, inseparable, for example, from the description of products on the page. If suddenly a search robot came across a file with the .sql extension, which for some reason ended up in working folder site, then it will be perceived as part of the content of the site and will also be indexed (including, possibly, the passwords specified in it).

Such information can be found by knowing stable, often unique, keywords that help separate “vulnerable pages” from pages that do not contain vulnerabilities.
A huge database of special queries using keywords (so-called dorks) exists on exploit-db.com and is known as the Google Hack Database.

Why google?
Doors are targeted primarily at google for two reasons:
- the most flexible syntax for keywords (shown in Table 1) and special characters (shown in Table 2);
- the google index is still more complete than that of other search engines;
