How SE works?
It operates in the following order:
Web crawling
Indexing
Searching
Web Crawling
A Web crawler is an Internet bot that systematically browses the World Wide Web,
typically for the purpose of Web indexing.
A Web crawler may also be called a Web spider, an ant, an automatic indexer, or a
Web scutter.
Web Crawling

Indexing
: collects, parses, and stores data (keywords or keyphrases) to facilitate
fast and accurate information retrieval.
Searching
: is the activity of obtaining information resources relevant to an information
needed from a collection of information resources.

You have a website,
but are you SEARCHABLE?
Search Engine Optimization

of affecting the visibility of a website or a web
page in a search engine's "natural" or unpaid
(organic) search results.

}
Organic Search results
Purpose of SEO
1. Brand awarenessA web site having a high ranking means
more people see the name of the
company and become familiar with the
company and its products.
2. Targeted TrafficSearch engine optimization brings
paying customers to your door step as
they enter your websites by using
relevant keywords/phrases into the
search engines.
3. Long term cost benefit Once you have achieved a good ranking
for a specific keyword, you will not pay
for the traffic it generates. Although it
has a higher entry cost, long term, its
very cost effective.
4. Brand credibility There is a higher level of brand trust
when a visitor finds you organically.
They are more likely to bookmark your
site, spend more time reading your site
and return as a customer.
5. Your competitors Keeping ahead of your competition in
the organic search results can help
boost the perceived position of your
company in your marketplace.
Optimization
On- Page SEO
Title Tags
The title tag tells search engines what the page is about and that the
page on your website is relevant for that keyword or keyword
phrase. Title tags should be unique for every page.
In search results, search engines will highlight your keyword phrases if a
user has searched for those terms. This increases visibility and clickthrough rate.
Example of Title tag in SERP
Best Practices:
• Your title tag should be written like this: Primary Keyword – Secondary Keyword | Brand Name
• Use a dash in between your keyword phrases and a pipe at the end before your brand name
• Avoid duplicate title tags
• Keep title tags at 66 characters or less in length, including spaces
Meta descriptions
Meta descriptions should include a compelling description on which a
user would want to click on. Much like title tags, the SERPs will highlight
keywords that the user searched for, increasing the likelihood of the user
clicking through to your website.
Example of Title tag in SERP
Best Practices:
• Write compelling meta descriptions
• 150 to 160 characters is the recommended length
• Avoid duplicate meta descriptions
• Do not use quotes or any non-alpha characters (Google, cuts them out of the meta description)
Content with Targeted Keyword Phrases
With the latest Google Panda updates, it is extremely important that your
content is unique and relevant.
If you have multiple pages with the same content (or if you have your
content on other people’s websites), you will run the risk of getting
penalized by Google and your search rankings will suffer.
Best Practices:
• Create content that is extremely relevant for that keyword phrase
• Use your keyword phrase 4 times within your content
• Use multiple variations of that keyword phrase – singular and plural versions,
abbreviations, acronyms (SEO vs. search engine optimization) and synonyms
• Include links from other pages within your website that point back to this page
• Create unique content for every medium (press releases, blogs, guest blog posts, etc…).
Example of Web Content with highlighted keywords
Website’s Meta data
Header Tags and Keyword Phrases
A header tag, also known as an H1 tag, is much like the subject line of
your web page. You should only use your keyword phrase once in the H1
tag.
This should be included on a page to which you are trying to drive
unique traffic to. You can also use H2 tags (second header) if there are
multiple sections.
Best Practices:
• Use your keyword phrase once in your H1 tag
• Use H1 tags on pages you are trying to drive unique traffic to (SEO page)
• Use H2 tags if there are multiple sections
Example of an
H1 tag being
optimized for
‘nfc reader’:
header tag 
Internal Page Linking with Anchor Text
Internal linking refers to a link on a page that points to another page on
the same website. Internal linking is important because it helps
strengthen those keywords internally for those pages, it allows users
(and search engine robots) to navigate through the website, and it tells
the search engines that the page is relevant for that keyword phrase.
Example of how to use anchor text in your internal links:
Best Practices:
• When linking to another page on the same site from within content, select good anchor
text (keywords) to use in the actual link and do this often.
Image ALT Tags and Filenames/Image
Optimization
An alt tag is essentially the name of an image. All images should use
appropriate alt tags. Not only are alt tags good for search engines; they
are also good for accessibility.
Example of image in a website with an alt tag.
Best Practices:
• Name all of your images in a way that describes what they are
• Use dashes between the words, rather than underscores ( purple-hat.jpg rather than
purple_hat.jpg)
• Do not use non-alpha characters in your image or file names (so no %, &, $, etc…)
How to Optimize Images
Find the right
images
Use the most
relevant and highquality image.
Make sure the
image matches
the content of
your page.
Use
keyword(s) in
the file name
Update your
image’s alt
attributes tag:
Use descriptive
text.
Using a keywordrich filename
helps search
engines determine
relevance.
<img
src="/img/contactle
ss_acr122_big.png"
alt="ACR122U USB
NFC Reader"
border="0">
Don't scale
the image via
HTML
Making an image
smaller or bigger
by using height
and width
different from the
image size is bad
for website
performance (and
image quality).
Create separate
files for different
image
sizes instead.
Make Content Easy to Read
This is not a huge factor in search engine rankings, but will help your
users easily scan your content and find the keywords they are looking
for.
You should use bolding and bullet points to set apart words in the text,
and this further tells the engines what is important on the page.
Best practices:
• Paragraphs should be roughly three sentences long. Extremely long sentences will lose
the users’ attention
• Use bullet points and bolding to break up large blocks of content. Users tend to scan
content looking for keywords
• Do not overuse bullets and bolding
Meta Keywords
Keywords or key phrases are the search terms someone types into a
search engine, when they are looking for certain information.
Why do KEYWORDS matter?
People are constantly using keywords whether they are in search of a specific
product or just browsing to conduct personal research.
XML Sitemaps
is an xml page on your website that incorporates a list of links in every
single page on your site.
It can also detail the hierarchy of pages on your site.
Sitemap content/code:
Note:
Without a quality sitemap, pages that are buried more than a couple of clicks from the
home page will take longer to get indexed and in some instances, Google (and other
search engines) may not index them at all.
Robots.txt
A Robots.txt file complements your XML sitemap by providing search
engine crawlers with instructions on how to read and index your website.
Robots.txt tells search engines which pages to index and which to skip, so that private
information stays protected.
Example:
Inside ACS’ robots.txt file…
Not indexed by Google
SEO Friendly URL
SEO-friendly URLs are purely structural URLs that do not contain a
query string:
[e.g., www.example.com/?p=578544]
but use keyword-rich naming conventions instead:
[e.g., www.example.com/products/smartcardreader]
Optimization
Off- Page SEO
Off-page SEO is all about building online authority –
trust and reputation – for your website.
It has been defined by the quantity, quality, and
relevance of links to your website that establish your
SEO authority and ultimately influence your search
results ranking.
Link Building
Is the practice of building inbound links to help give your website
authority.
WHY SEARCH ENGINES CARE ABOUT LINKS?
The number of backlinks is one indication of the popularity or
importance of that website or page.
Search engines’ major ranking factors that is put into consideration :
Search Engine Signals
SERP ranking
The Wrong Way to Build Links
• Spamming
• Buying a massive number of links
• Publishing low-quality article
• Over-using one article
Social Media

conversations with your audience.
Social media signals are
search engines’ signals as
natural ranking factors.
a. Bookmarking
A social bookmarking service is a centralized online service which
enables users to add, annotate, edit, and share bookmarks of web
documents.
b. Sharing

receive content.
c. PR

indexed by all major search engines.
Press release is a good tool for reputation management and search
engines’ ranking factor.
c. Interaction

opinions. If you can engage with visitors to your site, they will hang around for
longer. And the longer they hang around, the better exposed they are to your
brand.
Example of ACS’ social media account enhancing customer engagement by interaction:
c. Blogging
Content marketing, article writing or blogging is critical to your online visibility.
It generates search engine traffic by providing inbound links and can get you
leads for your business.
Example of ACS’ blog with inbound links to acs.com.hk:
c. Visual Content

data or knowledge intended to present complex information quickly and
clearly.
Example of a top ranking infographic from visual.ly with inbound link to the author’s blog:
