Site-level parameters
Description:
It is impossible to know how many pages Google correctly indexed on the site. The search engine does not maintain a database by URLs.
The approximate number of pages in the search results will be shown by the site operator, which we rely on. The number can be distorted by pages that are banned from indexing in robots.txt, but hit the search results because of external links to them.
The “Indexing Status” section in Google Search Console will show a slightly more correct number, but this data can also be distorted by the filters’ application.
Google scans websites to find infected resources, phishing pages, and other issues that degrade the search results and user experience. With this information, the search engine warns users about unsafe sites. If a site is deemed dangerous, Google might downgrade or remove it.
Additional Information:
Rank — 48 / 100
The button shows the current PR-CY rank indicator and allows you to quickly go to the analysis of the website.
Description:
PR-CY Rank is a rating for assessing the prospects of sites as donors for link building. We analyze traffic and trust parameters while forming the rating, as well as the link profile of the site.
Influence - the potential of the site's influence on promotion. If the influence is weak, then both the negative effect (if the rating is low) and positive (if the rating is high) will be weak, and vice versa. The influence potential is based on the size of the site's regular audience.
Link factor - calculation is based on the ratio of incoming and outgoing links to the site, values of Trust Rank, Domain Rank, etc.
Traffic factor - calculation is based on the volume and dynamics of traffic (negative dynamics spoils the rating, positive dynamics - increases).
Trust Factor - analyzes many parameters, such as "ICS", the part of search traffic in total traffic, adaptation for mobile devices and many other factors recognized by search engines as significant for ranking.

For successful indexing of the page by search bots, the HTTP response code of the server must be 200.
Additional Information:

- List of status codes
Description:
A robots.txt file is a list of restrictions for search robots or bots that visit a site and crawl information there. Before crawling and indexing your site, all robots go to the robots.txt file and look for rules.
The robots.txt file is located in the root catalogue of the site. It must be available on the URL: pr-cy.io/robots.txt
There are several reasons to use a robots.txt file on your site:
- to remove duplicate content;
- to hide unwanted information;
- to limit the indexing speed.
At least one sitemap has been found and is available.
Description:
A Sitemap file is a file with information about the pages on the site to be indexed. With this file you can:
- tell search engines which pages of your site need to be indexed;
- find out how often the information on the pages is updated;
- understand which pages are most important to index.
Additional Information:
For the promotion of commercial sites, the confidentiality of the exchange of information between the server and visitors is important. This increases the loyalty of potential customers to the resource, increases the level of trust, affects the conversion and growth of positions in the search results for almost all requests.
Description:
Technically, domains with www and without www are two different resources; search engines index and rank them separately, and links will have different weights. This can lead to:
- Decrease in search results
- Filter, because a search engine may mistake one site for a duplicate of another;
- Problems with authorization on the site and other functionality that uses cookies;
The problem is solved by a 301 redirect and an indication of the main mirror to the search engines. From the website promotion point of view, a domain without www is better, because it is not a third-level domain, and its length will always be shorter.
Download speed directly affects behavioral factors: the faster the download, the fewer bounces. The Google robot visits slow sites less often. This affects the effectiveness of promotion, such sites are rarely indexed. Loading speed is one of the main factors in Google ranking.
Description:
While requesting a non-existent page, the server should return a 404 error which is"page not found."
If the server is set up incorrectly and a 200 error returns, then the page exists. In this case, search engines may index all pages of the site with errors.
Set up the site in such a way that while requesting non-existent pages a 404 response code "page not found" or a response code 410 "page deleted" appear.
Description:
During requesting a non-existent page, the server displays a standard page with a 404 error. For the users’ convenience we recommend making a unique 404 page and adding a backlink to the site on it.
Statistics systems on the site take into account traffic, refusals, viewing depth and many other indicators. They help to track the effectiveness of promotion and advertising campaigns.
We found 1 site with same tag.
The test shows active and previously unplugged counters of statistics systems and related sites. This information can be useful if a competitor has projects unknown to you, the statistics of which are managed from one account so you can find them.
If something goes wrong in your counters, you can also find it out.
Sometimes Web studios independently install counters on clients' sites and manage them from the same account as the counter of their site. You can analyze the studio's website and, thanks to this test, find out who its clients are.

Encoding "UTF-8"
Description:
Due to incorrect encoding, site content may be displayed incorrectly. In addition to the fact that visitors will not like it, the site will not be indexed or will get under the search engines filter. We recommend using UTF-8 encoding to display the text on the site pages correctly. In some CMS, for example, Wordpress, files are written in this encoding, AJAX also supports only UTF-8.
Don't forget to include the encoding in your meta tags: <meta charset="UTF-8" />
Don't forget to prolong your domain name. It’s better to involve auto-renewal with your registrar. After the end of the domain registration, there is a chance to lose access to the domain.

**Description: **
Description is a tag that is used to describe a page for a search engine crawler, users do not see it. It should describe the content of the page correctly, because search engines often use the text from the Description to compose a snippet. It is better to place the keywords to the top, the text should not be repeated in other parts of the page. In the page code, the tag is placed between <head> and </head>. The optimal text size in the Description tag is 150-300 symbols for Google and up to 160 symbols for Yandex. It does not influence on SEO directly, while CTR depends on a good description.
The H1-H6 headers are responsible for the structure of the page's content. You need to highlight them in the layout to help the reader navigate the text. Headings are important for search engine promotion because search engines use them to determine what is on the page and how relevant it is. Arrange headers according to hierarchy and do not link to them.

Keyword density is one of the qualitative indicators of text, it shows the frequency of repetition of words in a document. "Keyword stuffing" is equal to the proportion of repeated words to the entire volume of the text.
A high level of Keyword density is considered to be 8%. Such texts are often hard to read, they are spammed. The pages they are hosted on have a high percentage of failures. A site with a lot of texts with a high Keyword density may receive sanctions from search engines.
Normal Keyword density is 4-6%. Almost all classical literature has this level of Keyword density.

External links are the links from you to another site. Try not to refer to resources with incorrect information that do not relate to your topic, choose useful and authoritative ones. Do not put too many external outgoing links and do not post them on your homepage. Selling the links negatively affects promotion.
Description:
With the help of internal links, you can influence the weight redistribution between individual pages of the resource, referring to more significant sections or articles. This weight redistribution is called linking and is used as part of internal site optimization.
Internal links influence behavioral factors - they simplify navigation and help the user to get to the necessary section faster.
