Graph Milestones

Milestones indicate the approximate date when the Web server was moved from one location to another. We specifically did not perform measurements at the time of the move (DNS requests may receive a different IP for the same domain from different locations, where the testing servers are located). Therefore we have the graph with two or more segments. It's a data measured before and after webserver was moved to the new location.

Why the low latency is important with this site as an example

To display this website browser needs to download 8 objects. Though modern browsers use parallel connection now, we'll simplify the conditions and calculate the time spent by the browser for these sites in a single-threaded mode. Time required to establish HTTP connection only: + preparation of the webserver response. Number 3 in the formula is a three phase of a TCP connection: sending a SYN request from the client to the server, sending ASK + SYN from the server to the client and the ASK sending from the client to the server. Though we can not calculate the time for a webserver response, the total time for sending and receiving requests for each of the object will be: Of course, modern browsers use several simultaneous connections to download content from a domain (from 2 to 8 at the time of writing this document). And in some browsers the number of connections can be set manually (Opera). But, if you impose these data on the first site Dota-utilities.com from the latency table for the city Mountain view, it turns out that the difference in time only for the sending and receiving requests to the web server could be: 0.1 sec. Sure, making such calculations must always take into account the audience site, and always make an accent on the fact that the server should always be so geographically closer to the primary audience as it possible. Also we recommend to pay attention to an article about importance of the latency on our site.

Page Speed Test

   

Page Speed

Page Speed is a key factor in the website speed estimations (along with DNS lookup speed and website latency). Speed of the page loading, sophisticated subdomains usage for static content (images, css), optimized code (html, js), hosting on fast servers with good latency to its audience leads to good results and, ultimately, to a good website profitability.

While conducting tests we emulate a visit your website using the browser Firefox 3.5.6. Test results of the page loading listed in this table:

Ways to improve website performance

Once the document (website's main page) has been downloaded, we analyze it. It allows us to give webmasters some recommendations on how to optimize page load speed. We analyze the internal and external factors.

Keep Components under 25K

Users often visit web site using a mobile phone. Even the most modern and advanced gadgets have some limitations. For example an iPhone browser do not cache page components bigger than 25K. So you should strive to ensure that scripts, CSS-styles, etc. are less than 25K.

Alternate text for the images.

As you may already know, search engine that indexes your pages, do not have eyes. And all content you are trying to display on your site is just HTML & CSS code, images, Flash, etc for the robots. It is It's extremely important to describe each of the objects more datailed using ALT, TITLE and other tags.

Our robot has determined that the google.com.vn page has 1 images, which has no tag ALT. Tag ALT is a text field, that specifies an alternate text for an image. But not only. Search engines consider this tag as a supplemental result for assessing the content of your page entirely. Do not ignore it!

For example your page has this code:

10.

<img src="/textinputassistant/tia.png" style="position: absolute; cursor: pointer; right: 5px; top: 4px; z-index: 300;" onclick="var s=document.createElement('script');s.src='/textinputassistant/0/vi_tia.js';google.append(s);" height="23" width="27">

We recommend you use rich img code in that place:

10.

<img src="/textinputassistant/tia.png" style="position: absolute; cursor: pointer; right: 5px; top: 4px; z-index: 300;" onclick="var s=document.createElement('script');s.src='/textinputassistant/0/vi_tia.js';google.append(s);" height="23" width="27" alt="kinh doanh">

P.S. We used keyword for this image that seemed to us most important for your page. But you can go ahead and give to each of 1 images an ALT text. This problem requires responsible approach. No need to put the same text at alt tag of the all images. Imagine that the pictures do not show and try to make sure that users understand what is shown on the picture based on the alt tag

Using H1 tag

Show main content of the page clearly. One of the most important internal website ranking factors is the H1 tag. It's a title of the document and the most powerful keyword, actually. Our robot did not find the h1 tag on the page.

Content Semantics

We suggest you along with important and well-known tags like Title & H1 use also H2, H3, H4, H5, STRONG tags. Each page can (and should) highlight not only the main topic, but also complement the semantic core of the page and the whole site with the secondary keywords. For example, if the main topic of the page is dedicated servers, there is a probability that page has a blog about managed dedicated servers. If so try to highlight the title of the block by using tag <H2>, and an information that you provide this service in the United Kingdom highlight with H3 tag and so on. Thus try to highlight every important fragment of the information on your page with tags like STRONG, H2, H3, etc. We did not find H2 tags, H3 tags, H4 tags, H5 tags, STRONG tags on the page

Use the TITLE for A tag

As we have already mentioned, search engine bots can not see the site like a people do it. They more focused on the descriptions of certain page elements. That's why we strongly recommend use TITLE operator in the "A" tag. This operator not only describes the page referenced by the page more detailed, but also takes part in the page describing. For example, you have the link on your website:

10.

<a href="http://www.google.com.vn/imghp?hl=vi&tab=wi" onclick="gbar.qs(this)" class="gb1">Hình ảnh</a>

We suggest you to remake it in this way:

10.

<a href="http://www.google.com.vn/imghp?hl=vi&tab=wi" onclick="gbar.qs(this)" class="gb1" title="hình ảnh">Hình ảnh</a>

Of course, you can (and should) use more proper phrase instead of the "hình ảnh" that describes the link http://www.google.com.vn/imghp?hl=vi&tab=wi.
