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 click-through rate.

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 nameAvoid duplicate title tagsKeep 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.

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)Slide24

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?

header tags & 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.Slide27

Best PracticesUse your keyword phrase once in your H1 tagUse H1 tags on pages you are trying to drive unique traffic to (SEO page)Use H2 tags if there are multiple sections
on-page
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.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.
internal page linking with anchor textSlide31
on-page
Example of how to use anchor text in your internal links:
on-page
Best PracticesWhen 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.
on-page
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.
alt tags, filenames and image optimizationSlide34
on-page
How to optimize imagesUse the most relevant and high- quality image.Using a keyword-rich filename helps search engines determine relevance.Use descriptive text.<img src="/img/contactless_acr122_big.png" alt="ACR122U USB NFC Reader" border="0">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.
on-page
Best PracticesName all of your images in a way that describes what they areUse 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…)
on-page
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.http://www.acs.com.hk/sitemap.xml
xml sitemapsSlide37
on-page
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.
xml sitemapsSlide38
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.

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]

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 phraseUse your keyword phrase 4 times within your contentUse multiple variations of that keyword phrase – singular and plural versions, abbreviations, acronyms (SEO vs. search engine optimization) and synonymsInclude links from other pages within your website that point back to this pageCreate unique content for every medium (press releases, blogs, guest blog posts, etc…).
content with targeted keywords
on-pageSlide43
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’ attentionUse bullet points and bolding to break up large blocks of content. Users tend to scan content looking for keywordsDo not overuse bullets and bolding
