Important Mobile Ranking Factors in 2017
Mobile First Indexing
Large File Sizes Weigh Down Your Mobile Site
The average mobile web page is 2.5MB in size. This means the
data alone takes 13 seconds to download on a fast 3G
connection. To make mobile sites faster, start by -
Minimize the Number of Fonts
Optimizing Images and reducing their size
Paring Down JavaScript File Sizes
Prioritize Above the Fold Content
Above the Fold
Below the Fold
“Element load order can make or break your page”
Instead of loading all elements together, prioritize the
resources that show above the fold.
Too many large file requests and ad tech requests
will slow a page down and harm the user experience.
Assess your ad-related calls to remove low
performing monetization partners
Server Requests Create Mobile Web Traffic Jams
Since every server request adds load time, you should review
each request on your site to understand the benefit it provides.
For this, here’s a 3 point check list -
Are you properly balancing synchronous (sequential) and
asynchronous (simultaneous) server requests?
Are ad set ups causing too much delay?
Are too many analytics trackers being used?
Optimizing For User Experience – Behavior Flow
Analysing the number of steps/clicks to the converting page
Think about the goal of your mobile site or app. Are you trying
to drive engagement, mobile commerce, registrations, calls, or
visits?
Flow of Traffic From One Page to Another
Looking at the Drop Off Rate at Different Pages
Check out the Top Mobile Content and Searches in Analytics
Optimize Mobile User Experience
“The more steps you have in your mobile experience, the more likely a user is to make an error or leave.”
For example, if a customer has just
filed a claim, they're presented with
its status and a click-to-call link to
contact their agent.
The result was a remarkable seven-
fold increase in claim submissions
and a 35% rise in the start-to-finish
rate for claim submissions
Display click-to-call buttons Put the calls-to-action
For Example, if a customer has
scrolled down to the bottom,
he has an option to click on
the call-to-action.
By Using a fixed call-to-action
on mobile Basecamp was able
to improve its CTR by 20%
Optimize Mobile User Experience Contd..
Take advantage of the built-in GPS capabilities
of smartphones
Zillow, anticipated needs by implementing a GPS-based
search feature on its mobile site and app to allow house
hunters to find listings nearby in just a few taps.
The result was more homes being viewed per session.
Load Time Really Matters
Walmart’s mobile site were confronted with a blank screen
for 7.2 seconds before content was loaded. So, the
company reduced page load time to 2.9 seconds.
For every second of improvement and experienced up to a
2% conversion rate increase.
Optimize Mobile User Experience – Other Points
Use Schema.org structured data
Because of the limited screen space, a search result with rich snippets is even more likely to stand out
than on a desktop.
Optimize titles and meta descriptions
Remember that you're working with less screen space when a user searches using a mobile device. To show off
your best work in SERPS, be as concise as possible
Design for the fat finger
Touch screen navigation can lead to accidental clicks if your buttons are too big, too small, or in the path
of a finger that's trying to get the page to scroll.
Mobile Usability Report – Google Webmasters
Mobile Usability Errors:
• Small font size
• Touch elements too close
• Viewport not configured
• Flash usage
• Fixed-width viewport
• Content not sized to
viewport
The tool will show you common usability issues with your mobile site, so that you can fix them and improve your mobile experience
for your users.
Mobile-friendly sites turn visitors into customers
Local SEO is Going Mobile
Mobile users search local - 88% of smartphone users

actively use local searches to research products and form the
right purchasing decision
Local search results = higher purchase rates - 18% of local
searches on a smartphone resulted in a purchase within one day

directories like the yellow pages through to mentions
on social media platforms. Keep your information
consistent so Google can trust it.
Get reviews, and you will reap any potential (likely small)
ranking benefits.
Mobile AMPlification
“Google’s mobile search
results, AMP pages are
indicated with a small
grey circle with a white
lightning bolt”
Google’s Accelerated Mobile Pages Project (AMP) is an open source
project geared toward enabling content to load instantly for mobile
readers
AMP’s lightning fast loading of content on a mobile
device is accomplished by:
• Pre-rendering the content while limiting the use of
JavaScript that publisher sites can use
• And caching content so Google doesn’t have to fetch
page content from the publisher’s server
According to Google, AMP cut down load time between 15% and 85%, in initial tests.
Why AMP ?
Faster Loading Pages for
Mobile Users
Increased Visibility/CTR
for Publishers & Sites
Improvement in
Rankings
AMP improves mobile friendliness. Thus, it
is highly likely that an AMP site will be
ranked higher than slower/Non AMP sites.
Click through rates improve for AMP
pages as search results will stand out &
users will seek quicker loading times.
Businesses that adopt AMP could help to
drive mobile abandonment rates down and
increase conversions.
Implementing AMP – 6 Points To Keep In Mind
Maintaining Two Versions Of a Page
Maintain at least two versions of any article page: The
original version of your article page that users see, and
the AMP version of that page.
Site template Modifications
It is also likely that you will have to rewrite your site
template to accommodate some restrictions. All CSS in
AMP must be in-line and be less than 50KB.
Image Tag
Multimedia must be handled specially. For example,
images need to utilize the custom amp-img element.
Video Tag
A custom tag must be used to embed locally hosted
videos via HTML5, called amp-video. There is a separate
extended component, amp-youtube for YouTube videos
Implementing AMP – 6 Points To Keep In Mind (Cont.)
AMP HTML Code
In order for Google to detect the AMP version of your
article, the original article page must include the following
tag:
<link rel="amphtml" href="http://www.example.com/blog-
post/amp/">
Structured Data
The AMP Discovery page also mentions that some
platforms that support AMP will require Schema.org
meta data to specify the content type of the page.
Schema.org meta data “is a requirement to make your
content eligible to appear in the demo of the Google
Search news carousel.
To remain competitive in mobile marketing, brands need to be able to measure how well they are helping
prospects complete their desired actions.
AMP-enabled content can help brands meet customers during “micro-moments”
Implementing AMP
I want-to-buy moments
I-want-to-go moments
I-want-to-do moments
AMP in Search
“I want to do” moments “I want to go” moments“I want to shop” moments
AMP For E-Commerce – User Journey: Step-1
“AMP is a natural fit for e-commerce because AMP makes webpages fast, and fast pages help with purchase
conversions” - Google
Users often start their journey from a site’s home page or a product
category page. These are great pages to AMPlify first
The content is typically static and available products are showcased.
Browsing Category Pages
AMP For E-Commerce – User Journey: Step-2
Landing On Category Page
User arrives at an AMP’ed product page after clicking on an item from a
featured listing on our e-commerce site’s home page.
AMP can help you create a rich beautiful page to showcase your product.
Add bold hero images and videos using the <amp-carousel> and <amp-
video> elements.
For sections with more detailed requirements or extended descriptions, use
the <amp-accordion> tag. In addition, enable users to share product links
with the <amp-social-share> element.
AMP For E-Commerce – User Journey: Step-3
Exploring Related Products & Converting
We know that users often change their mind and that sometimes the
initial product they are looking for isn’t the one they want, so let’s
show them more products.
With AMP, there are multiple approaches to show related products.
One approach is to statically publish a list of related products.
Another approach is to generate the list on the fly. To do so, just use
<amp-list> to fire a CORS request to a JSON endpoint which supplies
the list of related products.
The final piece of the puzzle comes in when the user is ready to make the purchase and taps on “Buy”. This is likely to be the
point of transition from an AMP-only environment to full HTML. Ensure that transition is as fast and consistent with the
experience they have had so far.
Few More Points AMP
• With AMP, you have to use a streamlined version of CSS.
• You are only permitted to use the JavaScript library that AMP provides – since you’re not
in control, you may experience lazy loading. This might be the only downside to AMP.
• For AMP sites to work every time, they must be properly validated
• No forms are allowed on AMP pages.
• For better experience, custom fonts have to be specially loaded.
• To avoid quirky-looking images, make sure to declare height and width.
• Use AMP-approved extensions if you want to have videos on your page.
