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.
Enable GZIP Compression
This is a good practice to give the user content in compressed form.
We've detected 394.96 Kb of content that could be compressed.
By compressing content you can achieve the size of ~ 98.74 Kb
(saving 296.22 Kb). This would accelerate the page loading speed and would positively
impact the bandwidth savings in New York University.

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.

Avoid 301 & 302 Redirects
Redirect allows you to make website or page available under many URLs. Webmasters use redirects
when their sites change domain name, several websites are merged into one, document is moved too
a new location, etc.
Using a redirect delays content obtaining. Any delay negatively affects on the user experience.
We've detected that page has 1 redirects before page components start loading.
The following list contains some of these redirects:
http://www.nyu.edu/content/nyu/en/admin/alerts.response.home.html redirects to http://www.nyu.edu/admin/alerts.response.home.html
Try to reduce the number unnecessary redirects.
Specify image dimensions
The browser needs to know the actual dimensions of image (width and height) to quickly render webpage.
We have detected that the 7 images has no width and height.
If you do not specify the width and/or height, then in order to
correctly display the image browser needs to download it and only then
put on the screen. Otherwise, there is a chance browser will display
elements under the picture inappropriately as well as the possible
presence of "jumping" effect of the page content (until the page load
is finished).
We provide below example of how to define the image /common/images/home/arrowsRight.gif dimensions:
| 401. |
|
<img src="/common/images/home/arrowsRight.gif" title="Next Slide" alt="Next Slide" width="IMAGE_WIDTH_HERE" height="IMAGE_HEIGHT_HERE"> |
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.
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:
| 77. |
|
<a class="offLeft" href="#contentWrapper">Skip to Content</a> |
We suggest you to remake it in this way:
| 77. |
|
<a class="offLeft" href="#contentWrapper" title="york university">Skip to Content</a> |
Of course, you can (and should) use more proper phrase instead of the "york university" that describes the link
#contentWrapper.
Number of links on the page
Try to avoid a large number of links on the page. Our robot
have found 143 links on this page. Google recommends
to keep the number of links fewer than 100.
