SiteSpeedLab Overall Website Rating for this website
Based on our speed test results table and considering features of the current webserver location (United kingdom, Welwyn garden city), we concluded
overall This website speed rank is 83. That means 83% of the sites from the Welwyn garden city are slower for visitors than this website.

It is important to understand that you can't evaluate website speed without considering website audience location. You should evaluate the speed of the site considering location of your primary audience (visitors), and not just from abstract tests from various points of the planet. There is a chance that your website is quite slow for visitors from German but pretty quick for Australian users at the same time. Based on a primary audience location data Site Speed Laboratory maintains objective rating. Test servers located in the United Kingdom and Usa are more useful and important to Tesco.com because the shares of each country are 90.70 and 1.40 percent respectively.

You should not overestimate the importance of the website speed factor. Google has more than 200 ranking factors and website speed is just one of them.

Content-Type's Weights by Hosts
 
 
Downloading page itself is the final stage of the testing. Actually, this is the last stage, after which page is displayed completely for user. The download speed depends on many factors. Main factors are the following: the width of the bandwidth up to the domain, the number of simultaneous download threads, speed of the server, a distance between user and domain web server. Recent measurements have shown the speed of page download for this domain is 162.366Kb/s (which is better than 83% of all sites in this region).

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 tesco.com page has 3 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:
730.   <img src="/homepages/default/i/right.top.png" height="90" width="128">
We recommend you use rich img code in that place:
730.   <img src="/homepages/default/i/right.top.png" height="90" width="128" alt="home shopping">


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 3 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

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:
457.   <a id="hp_topaccess" href="/access/" name="hp_topaccess">Visually impaired? Find out about our accessible grocery web service</a>
We suggest you to remake it in this way:
457.   <a id="hp_topaccess" href="/access/" name="hp_topaccess" title="online grocery shopping">Visually impaired? Find out about our accessible grocery web service</a>
Of course, you can (and should) use more proper phrase instead of the "online grocery shopping" that describes the link /access/.

Number of links on the page

Try to avoid a large number of links on the page. Our robot have found 186 links on this page. Google recommends to keep the number of links fewer than 100. More information about this topic you can find in Google Webmaster Guidelines and in the post "How many links per page?" by Matt Cutts (head of Google’s Webspam team)
