The A record maps a domain name to an IPv4 address, while the NS record specifies authoritative name servers for a domain. The MX record identifies the mail server responsible for receiving email messages for a domain. Additionally, the TXT record allows for the association of any text information with a domain name. These records play a vital role in ensuring proper communication and connectivity across the internet.

SEO Analysis

SEO analysis involves examining the performance of a website, including titles, descriptions, keywords, and website speed. It also includes identifying popular keywords and researching competitor websites to understand their strategies. The analysis aims to optimize the website's visibility and improve its ranking on search engines.

Title Tag:
Free Javascript challenges online | JSchallenger

Length: 48 characters

Title tags are usually best kept short, within 50-70 characters. It's important to note that search engines will typically read the entire title tag even if it exceeds 70 characters, but there is a chance they may cut it off or disregard it.

Meta Description:
JSchallenger. Free Javascript challenges. Learn Javascript online by solving coding exercises. Javascript for all levels. Solve Javascript tasks from beginner to advanced levels.

Length: 178 characters

What is the issue about?
TThe description is too long or too short. Search engine crawlers only show the first 150-160 characters of the description in the search results page, so if a description is too long, searchers may not see all of the text. If a description is too short, the search engines may add text found elsewhere on the page. Note that search engines may show a different description from the one you have authored if they feel it may be more relevant to a user's search.

How to fix?
Change the description in the tag in the page source to be between 25 and 160 characters in length.

Meta Keywords:

No meta keywords found.

In the realm of search engine optimization, the meta keywords tag has become a relic of the past due to its potential for misuse, ultimately leading major search engines to disregard it in their ranking algorithms.

Keywords Cloud:

A crucial factor in search engine optimization is keyword density, which refers to the proportion of a particular keyword present in the text of a webpage. In order to achieve high rankings on search engine results pages, it is essential to maintain the appropriate keyword density for your primary keyword.

In SEO, the primary focus is placed on keywords within the content. The title of the page holds the highest importance, followed by heading tags such as h1, h2, and h3. The h1 heading should be the largest on the page, while the h2 heading should be slightly smaller, and the h3 heading even smaller. This hierarchical structure is crucial for optimizing search engine rankings.

Image Alt Attribute:
16 images found in your page, and 12 images are without "ALT" text.

What is the issue about?
The tag does not have an ALT attribute defined. As a general rule, search engines do not interpret the content of image files. The text provided in the attribute enables the site owner to provide relevant information to the search engine and to the end user. Alt text is helpful to end users if they have images disabled or if the image does not properly load. In addition, the Alt text is utilized by screen readers. Make sure that your Alt text is descriptive and accurately reflects what the image represents and supports the content on the page.

How to fix?
Use the <img alt> attribute to write descriptive content for the image: <img source='pic.gif' alt='Accurate and descriptive keyword text that represents the image.' />.

Website Speed Test (Desktop):
0.01 seconds

Website speed is a measurement of how fast the content on your page loads. Website speed is one of many factors involved in the discipline of search engine optimization (SEO), but it is not the only one. In a recent study, the average load time for a web page was 3.21s.

CO-Hosted

CoHosted refers to a situation where multiple domain names (websites) are using the same IP address to point to their respective web servers. They could be owned by different individuals or organizations and may serve entirely different purposes.
