Knowledge Base

Ideally, your Title tag should be less than 60 characters.

Meta Description

Meta Description :


Your site does not have a meta description.

Knowledge Base
A meta description is an HTML and XHTML element that describes your page to search engines. While the perceived (and real) importance of meta data has depreciated, the attribute still plays an important role in SEO rankings.

Meta descriptions can be any length, but search engines generally truncate snippets longer than 160 characters. It is best to keep meta descriptions under 150 characters.

Meta Keyword

Meta Keyword :


Your site does not have any meta keywords.

Knowledge Base
Although many SEO experts will tell you that keywords are no longer relevant for SEO, the effort to add keywords is so minimal that we continue to advise that keywords be used as part of your SEO.

Keyword Usage

The most used keywords do not match your meta keywords.

Knowledge Base
Keyword consistency means having the keywords or sets of keywords that you want to rank for in searches spread over all the elements of a particular web page.

This should not be confused with keyword density. Keyword density means the number of times a keyword is featured in the website content and this practice is no longer a deciding factor in improving the search ranking of your website.

Keyword consistency, on the other hand, is a logical consideration for ranking high in search results, given that the keywords chosen for a particular web page indicate the category or topic of the page, and this is what search engines are looking for.

Total Words

Total Words : 1143

Knowledge Base
Unique words are uncommon words that reflects your site features and informations. Search engine metrics are not intended to use unique words as ranking factor but it is still useful to get a proper picture of your site contents. Using positive unique words like complete, perfect, shiny, is a good idea user experience.

Stop words are common words like all the preposition, some generic words like download, click me, offer, win etc. since most used keyword may be a slight factor for visitors you are encouraged to use more unique words and less stop words.

Text/HTML Ratio Test

Site passed text/HTML ratio test.

Text/HTML Ratio Test : 35%

Knowledge Base
The ideal page's ratio of text to HTML code is between 20% to 60%. A result of less than 20% it means you need to write more text on your web page while if more than 60% your page might be considered as spam.

Knowledge Base
Heading tags, as their name suggests, are used to differentiate the headings and sub-headings of a page from the rest of the content. These tags are also known to webmasters as HTML header tags, head tags and SEO header tags. The most important heading tag is the H1 tag and least important is the H6 tag.

The H1 is the most important tag and it should never be skipped on a page. Search spiders pay attention to the words used in the H1 tag and it should contain a basic description of the page content, just as the page title does.

robot.txt

Your site has a robot.txt file.

Knowledge Base
When search engine spiders crawl a website, they typically start by identifying a robots.txt file at the root domain level. Upon identification, the crawler reads the file directives to identify directories and files that may be blocked. Blocked filed can be created with the robots.txt generator; these files are, in some ways, the opposite of those in a website sitemap, which typically includes pages to be included when a search engine crawls a website.

Sitemap

Your site has a sitemap
Location: http://amdstone.vn/sitemap.xml

Knowledge Base
Sitemaps are a list of pages on a website that is accessible to all users. An XML sitemap is a way for website owners to tell search engines about all the pages that exist on their website and which links on your website are more important than others along with how frequently you update your website.

While sitemaps do not boost your search rankings, it allows search engines to better crawl your website and every website should have one.

Also keep these things in mind:
1) Sitemaps must be less than 10 MB (10,485,760 bytes) and can contain maximum 50,000 urls. if you have more uls than this create multiple sitemap files and use a sitemap index file.
2) Put your sitemap in your website root directory and add the url of your sitemap in robots.txt.
3) sitemap.xml can be compressed using grip for faster loading.

GZIP Compression

GZIP Compressed Size : 9 KB


GZIP compression is enabled.

Knowledge Base
GZIP is a generic compressor that can be applied to any stream of bytes: under the hood it remembers some of the previously seen content and attempts to find and replace duplicate data fragments in an efficient way - for the curious, great low-level explanation of GZIP. However, in practice, GZIP performs best on text-based content, often achieving compression rates of as high as 70-90% for larger files, whereas running GZIP on assets that are already compressed via alternative algorithms (e.g. most image formats) yields little to no improvement. It is also recommended that, GZIP compressed size should be <=33 KB

URL Canonicalization Test

Site failed URL canonicalization test.

Canonical tags make your all urls those lead to a single address or webpage into a single url. Like :
<link rel="canonical" href="https://mywebsite.com/home" />

Server Response Time

In our test, your server responded in 0.25 seconds. There are many factors that can slow down your server response time.
Please read our recommendations to learn how you can monitor and measure where your server is spending the most time.

Minify CSS

Compacting CSS code can save many bytes of data and speed up download and parse times.
Minify CSS for the following resources to reduce their size by 10.3KiB ( 18% reduction ).

  • http://amdstone.vn/publics/css/style.css could save 9KiB ( 19%reduction )
  • http://amdstone.vn/publics/css/responsive.css could save 1.2KiB ( 13%reduction )

Minify HTML

Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
Minify HTML for the following resources to reduce their size by 2KiB ( 24% reduction ).

  • http://amdstone.vn/ could save 2KiB ( 24%reduction )

Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 16.3KiB ( 57% reduction ).

  • http://amdstone.vn/publics/scripts/js.slide.js could save 12.6KiB ( 82%reduction )
  • http://amdstone.vn/publics/scripts/jshover.js could save 3.7KiB ( 29%reduction )

Render-blocking JavaScript and CSS

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Render-blocking JavaScript

  • http://amdstone.vn/publics/scripts/jquery1.4.js
  • http://amdstone.vn/publics/scripts/js.menu.js
  • http://amdstone.vn/publics/scripts/jshover.js
