Alt attributes are a way to describe images to search spiders simply because
search spiders cannot see them. It is not only an opportunity to add more
content (with keywords) to your site, but it also helps your images to be
searchable on Google. For best results, all images should also have distinct
filenames.
Alt tags were originally designed to be displayed as an alternative text to
an image in cases when an image cannot be displayed in a browser. Also, alt
tags are displayed when users rest their mouse on the image.
2. Title Tags
A title tag describes an online document and has the most SEO power for
establishing keyword relevance on the page. The Title tag appears at the
very top of a browser or tab window, in search result pages, and external
websites.
At 59 characters or less (including spaces), the title tag should include a
few relevant keywords and a company or brand name. Important keywords should
be placed at the beginning of the title tag. It is recommended to avoid
using stop words such as "the," "is," "can," "and," "but," "while," "that,"
"we," etc. that have no keyword value.
3. Meta Descriptions
Meta tags give search spiders a summary of what the page is about. Meta
descriptions play an important role in search results and gaining users
click-through. Google sometimes uses this summary to display in search
result pages (SERPs) and highlights keywords relevant to the search query.
The optimal length of meta description is between 159 characters and should
include keywords that are relevant to the title tag and content. Consider
this an opportunity to advertise the content of your page to searchers.
Ideally, each page should be optimized around one main key phrase that
should be included in your title tag, meta description, and content.
4. Sitemap.xml
Google uses Sitemaps to learn about a website's structure, which allows a
better crawling of your site. Creating a Sitemap ensures that search spiders
know all the pages of your site that may not be discoverable through the
normal crawling process.
Sitemaps are also used to provide metadata about specific types of content
on your site such as video, images, mobile, and news. Sitemap.xml files
reside in the website main directory and have to be submitted to Google
using Google Webmaster Tools.
5. Robots.txt
In addition to Sitemaps, a robots.txt file is used to instruct search engine
robots about access to your site. Before accessing pages of a site, search
spiders check the robots.txt file to see if it restricts them from accessing
certain pages. You only need a robots.txt file if the directory of your site
includes content that you don't want search engines to index. The robots.txt
file resides in the main directory of your site.
6. Rich Snippets and Microdata
High ranking on the search engine result pages (SERPs) is no longer the only
problem to solve with website optimization. When searchers glimpse through
result pages they look for additional relevant information to their query
before they click-through. Rich snippets provide searchers with that
information and help them quickly decide if the content that exists on a web
page is relevant.
To implement rich snippets web developers have to add additional HTML markup
to a website. One of the most used markups is microdata. Using simple HTML
tag microdata allows you to indicate specific type of information: reviews,
people, products, businesses and organizations, recipes, events, music and
video content.
7. Code Restructuring
Though search algorithms have changed dramatically since their original
inception, search spiders still don't search deep into a site and don't
spend much time on any given page. With this in mind, code restructuring of
some pages is still a valid addition to any advanced SEO techniques. Web
developers restructure a page (without affecting a page layout) in a way
that places content higher in the code. This helps spiders quickly find
relevant information.
The above advanced SEO techniques will significantly improve your website's
online visibility, but that's not the limit of SEO optimization that can be
done to a website. A website can be further optimized for better usability
with accesskeys (use of keyboard shortcuts), tabindex (use of tab key to
navigate through a page), and web accessibility for people with
disabilities. It might sound like unnecessary optimization, but everything
that makes a website more human friendly is highly valued by search engines.
