History data is found for this test!
Changes found in history for 5 months. First date: Feb 2022.

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 Safe Browsing
The site is secure.

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.

PR-CY Rank
History data is found for this test!
Changes found in history for 3 months. First date: Feb 2022.

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.

Robots.txt
Robots.txt file found. The site is allowed for indexing.

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:

  1. to remove duplicate content;
  2. to hide unwanted information;
  3. to limit the indexing speed.

  • 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:

SSL-certificate
The site is accessible via HTTPS. The certificate is valid until 06/21/2025.

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.

Updated 03/24/2025 21:07
WWW redirect
Redirection is configured.

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.

Updated 03/24/2025 21:07
HTML loading speed
2.17 sec - faster than 9% of tested sites.

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.

Updated 03/24/2025 21:07
404 page response code
Great, received code 404.

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.

Updated 03/24/2025 21:07
Link from 404 page
Link from 404 page found.

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.

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.

Page Encoding
Encoding specified in head is UTF-8
Encoding specified in html is 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" />

Domain age
3 years
Young and new domains are poorly promoted in highly competitive topics. The history of the domain and site is also important. Old domains with a bad history are difficult to promote. Search engines love old, topical domains with a good history (no filters, spam, black SEO, etc.).

Expiration Date

Length: 0 characters. Found: 0 tags.

**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.

Keywords density (without stop words)
4.24%

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.

Adult content

Not found.

Description:

The service searches the words on sites that can be classified as pornography. Search engines are struggling with showing 18+ content, so they remove sites with pornographic materials from the ranking for other requests.

Even if you have not posted such materials on the site, they may appear as a result of a hacked site or in the comments.

What to do:

  • do not use words, images and videos of a pornographic nature;
  • check ads on your site, switch off showing 18+ ads if they are shown by default;
  • check users’ reviews and comments;
  • if you link to another site, make sure that there is no adult content and links to such sites.
