SEO

Title Tag

ACM Digital Library

Length: 19 character(s)

?


Your HTML title tag appears in browser tabs, bookmarks and in search result pages.

Make your title tags clear, concise (50-60 characters) and include your most important keywords.

Check the title of your website

Meta Description

www.acm.org - The premier society in computing brings you the Computer Portal.

Length: 78 character(s)

?

Great, your meta description contains between 70 and 160 characters (spaces included).

A good meta description acts as an organic advertisement, so use enticing messaging with a clear call to action to maximize click-through rate. They allow you to influence how your web pages are described and displayed in search results.

Ensure that all of your web pages have a unique meta description that is explicit and contains your most important keywords (these appear in bold when they match part or all of the user’s search query).

Check your Google Search Console account (Click 'Search Appearance', then 'HTML Improvements') to identify any issues with your meta descriptions, for example, they are too short/long, or duplicated across more than one page.

?
This is a representation of what your Title Tag and Meta Description will look like in Google search results.

Search engines may create their own titles and descriptions if they are missing, poorly written and/or not relevant to the content on the page and cut short if they go over the character limit. So it’s important to be clear, concise and within the suggested character limit.

Headings

We did not find HTML headings (<H1> to <H6>) on this page.

?

HTML header tags (or simply header tags) differentiate between headings, subheadings and the rest of the content on the page.

Your website either does not currently use HTML header tags or is using too many. Use keywords in your headings with your most important keywords in the top level, and be sure to maintain the <H1> to <H6> hierarchy.

While it is important to ensure every page has an <H1> tag, never include more than one per page. Instead, use multiple <H2> - <H6> tags.

Add the important keywords in <H> headings

This Keyword Cloud provides an insight into the frequency of keyword usage within the page.

It's important to carry out keyword research to get an understanding of the keywords that your audience is using. There are a number of keyword research tools available online to help you choose which keywords to target.

Keyword consistency is the use of keywords throughout the different elements of the webpage. Consistent keyword use helps crawlers index your site and determine relevancy to search queries.

The table above highlights the most frequently used keywords on your page and how consistently you're using them.

Be more consistent with your keywords

Alt Attribute

We found 31 images on this web page.

16 ALT attributes are empty or missing.

  • http://dl.acm.org/images/blanks.gif
?

Alternative text allows you to add a description to an image. Since search engine crawlers cannot see images, they rely on alternative text attributes to determine relevance to a search query. Alternative text also helps makes an image more likely to appear in a Google image search and is used by screen readers to provide context for visually impaired users.

It looks like you're missing alt text for several images on your page. Check the images on your website to make sure accurate and relevant alternative text is specified for each image on the page.

Try to minimize the number of alt text characters to 150 or less (including spaces!) to optimize page load times.

Set a name for all your images

Discovered Pages

213,352    213,352
?

This is the number of pages that we have discovered on your website.

A low number can indicate that bots are unable to discover your webpages, which is commonly caused by bad site architecture & internal linking, or you're unknowingly preventing bots and search engines from crawling & indexing your pages.

Make sure your website's XML sitemap is present and you have submitted it to the major search engines. Building backlinks to your website's internal pages will also help bots to discover, crawl and index them, while building authority to help them rank in the search engines.

Check Google™ Search Console under 'Google Index' and 'Crawl' to keep track of the status of your site's indexed/crawled pages.

Write more content

IP Canonicalization

Yes

?

Good, your website's IP address is forwarding to your website's domain name.

To check this for your website, enter your IP address in the browser and see if your site loads with the IP address. Ideally, the IP should redirect to your website's URL or to a page from your website hosting provider.

If it does not redirect, you should do an htaccess 301 redirect to make sure the IP does not get indexed.

Robots.txt

?

A robots.txt file allows you to restrict the access of search engine crawlers to prevent them from accessing specific pages or directories. They also point the web crawler to your page’s XML sitemap file.

Your site currently has a robot.txt file. You can use Google Search Console's Robots.txt Tester to submit and test your robot.txt file and to make sure Googlebot isn't crawling any restricted files.

Add a robots.txt file

XML Sitemap

Missing

?

XML sitemaps contain the list of your URLs that are available to index and allows the search engines to read your pages more intelligently. They can also include information like your site’s latest updates, frequency of changes and the importance of URLs.

Your site is currently missing an XML sitemap. We recommend you generate one for your site and submit it through both Google Search Console and Bing Webmaster Tools.

Make sure to only include the pages you want search engines to crawl, so leave out any that have been blocked in a robots.txt file. Avoid using any URLs that cause redirects or error codes and be consistent in using your preferred URLs (with or without www.), correct protocols (http vs. https) and trailing slashes. You should also use your robots.txt file to point search engine crawlers to the location of your sitemap.

Add and Optimize your XML sitemap

URL Rewrite

Warning! We've detected parameters in a significant number of URLs.

?

Clean URLs are important for both human usability and SEO. They let users know what page they're on and help search engines determine if the page is relevant to a keyword search.

Right now your site's URLs use unnecessary elements like parameters. We suggest you rewrite your URLs to make them less complicated. Keep your URLs simple and use the page's most important keywords. Clean URLs are also useful when shared on social media as they explain the page's content.

Rewrite your URLs and clean them up.

Underscores in the URLs

We found underscores in this URL and/or in your in-page URLs.

  • http://dl.acm.org/browse_dl.cfm?linked=1&part=affil&coll=DL&dl=ACM&CFID=560865722&CFTOKEN=44215617
  • http://dl.acm.org/browse_by.cfm?type=all&by=pub&CFID=560865722&CFTOKEN=44215617

  • http://dl.acm.org/ocr_review_main.cfm?CFID=560865722&CFTOKEN=44215617
?

Using underscores in your URL makes it hard for search engines to determine your site's relevance to a search. Google sees hyphens as word separators while underscores are ignored. So the search engine sees www.example.com/green_dress as www.example.com/greendress.

We've detected underscores in your URLs. Change underscores to hyphens to maximize your SEO.

Blocking Factors

Flash: No

Frames: No

?

Great, you aren't using Flash or frames on your site.

While it often looks nicer, Flash content can't be properly indexed by search engines. Maximize your SEO efforts by avoiding Flash.

Search engines also have problems with frames because they can't crawl or index the content within them. Avoid them if you can and use a NoFrames tag when you can't.

Blog

We have not found a Blog on this website.

?

In a crowded digital marketing world, content is king. Publishing your content on other sites is beneficial, but publishing it on your own site is much more effective. One of the best ways to do this is through a blog.

We recommend you start a blog to engage with your audience and improve your online visibility to attract qualified traffic from a variety of new sources. Use our tips to get the most out of your blog.

If you don't think a blog would work for your site or business, consider publishing other forms of evergreen content such as guides or whitepapers.

Mobile-friendliness

Poor    Poor

This website is not optimized for Mobile Visitors

Mobile CSS

Mobile Redirection

?

Mobile friendly websites make it easy for users to complete their objectives and common tasks and use a design or template that is consistent across all devices (uses responsive web design).

Google released a new mobile ranking algorithm that expanded the use of mobile-friendliness in its mobile search rankings. With almost half of all Google search queries originating on a mobile device, it is important to make sure your mobile site is optimized for these users.

Mobile Rendering

dl.acm.org on an iPhone
dl.acm.org on an iPad
?

80% of adult Internet users now have a smartphone. You should definitely be optimizing your website to render on the most popular mobile devices.

Touchscreen Readiness

Make the most important buttons/links large enough to be tapped easily.

?
Touchscreen readiness is an important aspect of your site’s mobile friendliness. Your tap targets should be at least a 48 pixels in height and width with at least 32 pixels of extra space on all sides. You can further improve your User Interface by adding size and density buckets to accommodate varying device sizes and screen densities.

Mobile Compatibility

Perfect, no embedded objects detected.

?
Great, your website does not embed any special types of web content, such as Flash, Silverlight or Java, so your content can be accessed on all devices.

Font Size Legibility

This web page’s text is too small for legibility on mobile devices.

?

The text on your homepage is too small, impacting your mobile friendliness. To fix this, first make sure your viewport is configured. You can do this using our Mobile Viewport criteria below.

Next, implement the recommendations below:

  • Use a base font size of 16 CSS pixels.
  • Use sizes relative to the base size to define the typographic scale.
  • The general recommendation for spacing between characters is 1.2em.
  • Restrict the number of fonts used and the typographic scale.

Mobile Viewport

This page does not specify a viewport, or the viewport is not well configured.

The content fits within the specified viewport size.

?

The viewport is an element of a page’s responsive design. It’s the area of a webpage visible to the user and varies between devices.

It looks like your page could be missing a meta viewport.

Use the meta viewport tag in the <head> to set the viewport to the device’s screen size. It should look like this: <meta name=”viewport” content=”width=device-width, initial-scale=1.0”>.

Mobile Speed

Average    Average

Optimize images

Leverage browser caching

Eliminate render-blocking JavaScript and CSS in above-the-fold content

Prioritize visible content

Enable compression

?

Like with desktop, the time it takes a mobile page to load is an important mobile ranking factor. Your mobile/responsive website must deliver and render the “above the fold” content in under one second.

Since mobile device CPUs are less powerful than desktop CPUs, speed tips that reduce CPU consumption (for instance JavaScript Parse time) need to be addressed first.

See Google's PageSpeed Insights Rules for more information on how to improve each of the elements in this section.

Mobile Frameworks

No mobile frameworks have been detected.

?
Mobile or responsive frameworks are an important part of website optimization as they assist developers in creating applications which are applicable to multiple devices.

Usability

URL

dl.acm.org

Length: 3 character(s)

?

Keep your URLs short and clean and avoid long domain names when possible.

A descriptive URL is better recognized by search engines. A user should be able to look at the address bar and make an accurate guess about the content of the page before reaching it (e.g., http://www.mysite.com/en/products).

Keep in mind that URLs are also an important part of a comprehensive SEO strategy. Use clean URLs to make your site more "crawlable" by Google™.

Resource: Search for a good domain name. If no good names are available, consider a second hand domain. To prevent brand theft, you might consider trademarking your domain name.

Favicon

Great, your website has a favicon.

?

Favicons are the small icons that appear next to your site’s name or URL in a browser. They can be displayed in the address bar, a browser tab title or bookmarks. Make sure it is consistent with your brand.

Here is a way one company used a special favicon to improve user experience.

Add a Favicon

Page Size

58.8 KB (World Wide Web average is 2 Mb)

?

Two of the main reasons for an increase in page size are images and JavaScript files. Large page size contributes to slow page speeds so try to keep your page size below 2 Mb.

Tip: Use images with a small size and optimize their download with gzip.

Load Time

0.11 second(s) (560.01 kB/s)

?

Your website is fast. Well done.

Site speed is an important factor for ranking high in Google™ search results and enriching the user experience.

Resources: Check out Google™'s developer tutorials for tips on how to to make your website run faster.

Monitor your server and receive SMS alerts when your website is down with a web monitoring service.

Language

Declared: English

Detected: English

?

Great, your declared language matches the language detected on the page.

Make sure your declared language is the same as the language detected by Google.

Tips for multilingual websites:

  • Define the language of the content in each page's HTML code.
  • Specify the language code in the URL as well (e.g., "mywebsite.com/fr/mycontent.html").

Declare the language used

Structured Data Markup

No Structured Data Markup has been detected

?
Structured Data Markup is used to generate Rich Snippets in search engine results. It is a way for website owners to send structured data to search engine robots; helping them to understand your content and create well-presented search results.

Get the most out of Google's rich snippets for content types such as: Reviews, People, Products, Businesses and Organizations, Recipes, Events, Videos and Music. If your website covers one of these topics, then we suggest that you annotate it with Schema.org using microdata.

Speed Tips

Warning: your website’s speed could be slightly improved.

Perfect, your server is using a caching method to speed up page display. 

Too bad, your website is using nested tables, which can slow down page rendering.

Too bad, your website is using inline styles.

Perfect, your website has few CSS files.

Perfect, your website has few JavaScript files.

Too bad, your website does not take advantage of gzip.

?

Website speed has a huge impact on performance, affecting user experience, conversion rates and even rankings. ‪‬‬By reducing page load-times, users are less likely to get distracted and the search engines are more likely to reward you by ranking your pages higher in the SERPs.

Conversion rates are far higher for websites that load faster than their slower competitors.

See Google's PageSpeed Insights Rules for more information on how to improve each of the elements in this section.

Analytics

We didn't detect an analytics tool installed on this website.

?

Web analytics let you measure visitor activity on your website. You should have at least one analytics tool installed, but It can also be good to install a second in order to cross-check the data.

Popular Analytics Tools Include: Google™ Analytics, Quantcast™, AdobeAnalytics™, Piwik™, chartbeat™, Clicky™, ClickTale™, etc.

W3C Validity

Invalid: 905 Errors, 1,385 Warning(s)

?

W3Cis a consortium that sets web standards.

Using valid markup that contains no errors is important because syntax errors can make your page difficult for search engines to index. Run the W3C validation service whenever changes are made to your website's code.

Fix the errors in the code syntax

Doctype

XHTML 1.0 Transitional

?

The Doctype is used to instruct web browsers about the document type being used. For example, what version of HTML the page is written in.

Declaring a doctype helps web browsers to render content correctly.

Encoding

Great, language/character encoding is specified: ISO-8859-1

?

Specifying language/character encoding can prevent problems with the rendering of special characters.

Directory Browsing

No

?

Great! Your server prevents visitors from browsing your directory by accessing it directly, this is excellent from a security standpoint.

Server Signature

No

?
Turning off your server signature is highly recommended to ensure the security of your website.

SSL Secure

Great, your website is SSL secured (HTTPS).

Your website's URLs do not redirect to HTTPS pages.

Your headers are not properly set up to use STS.

The SSL certificate expires in 8 months.

The certificate issuer is DigiCert Inc.

?
Modern websites tend to be SSL secured (HTTPS) as it provides an extra security layer while logging in to your Web Service. In 2014, Google™ announced that an HTTPS (vs HTTP) website would receive an extra boost in their ranking.

While switching to HTTPS, make sure your site remains optimized and see to it that your website will still run quickly. Follow these best practices for a smooth transition:
  • Use a serious issuer to purchase your SSL certificate
  • Redirect all of your HTTP pages to the HTTPS version of your website
  • Use a Security Token Service (STS) in your headers
  • Renew your SSL certificate every year, before it expires
  • Make sure that all of your content (CSS, etc.) is linked to HTTPS
  • Update your XML sitemap to ensure the URLs include HTTPS and update the robots.txt file to reference this version
  • Register the HTTPS website in Google & Bing Search Console/Webmaster Tools
