What is search engine optimisation?
Search engine optimisation still is the most effective method for companies to reach their customers. Search engine optimisation refers to all activities aimed at increasing visibility for your website, brand, products and services on Internet search engines. Search engine optimisation in the U.K. and most of Europe typically targets the main search engine used by over 90% of Internet users – Google.
The science of search engine optimisation
Owing to its extreme popularity, SEO for Google has become a science in itself. Optimising content requires a thorough understanding of how search engines work. It also requires a good understanding of what you should not do to raise your organic search ranking, since Google is now smart enough to detect when a website is trying to spam the search algorithm to raise its own profile.
Why do you need SEO?
Search engine optimisation is an online marketing strategy that involves designing, writing and coding your entire website with the intention of enabling search engines to index your site easily and rank it higher for keywords relevant to your business.
Search engine usage
Over 49% of business professionals use the internet as their primary source of information. Over 60% of internet users discover new businesses and websites through search engines. That means on any given day millions of searches are being performed online. Optimising your website for search engine visibility increases the probability that web searchers will visit your website.
Obtaining search engine and directory listings
Certain search engines, such as Google crawl through interlinked web pages, build lists of words and phrases found on each web page and discover new sites through links on these pages. For spider-based search engines the best way to get indexed and listed is by optimising your site and then making sure other sites that are already listed link to yours.
Other search destinations such as Yahoo! are based on directories that are compiled by human editors and have lists of websites indexed with the site title and description. The only way to get listed on a directory is to closely follow their submission guidelines and submit your website using their online submission form. Optimising the header section of your HTML pages is most important to get properly listed on most directories.
Search engine rankings
Merely getting listed and indexed on a search engine is no longer enough to bring you business. Google has over 8 billion websites in its index. For your website to shine out and rank high for relevant searches, it is imperative that you optimise it for those keywords.
Search engine optimisation endeavours to design web pages with the intention of getting them to rank higher on the search engine results pages. Without optimisation, you site will more likely than not be lost among the millions of other sites.
What are the most effective keywords?
Ranking number one on Google does not necessarily mean you will suddenly receive a flood of visitors and new customers. You need to rank at the top for keywords that are actually searched for by your visitors.
A lot of marketing executives and companies make a mistake commonly known as “me marketing”. They assume that what they think, feel and want is what their customers will want too. The most common transference of this syndrome in the world of search marketing is when companies claim that they have their SEO work sorted because they already rank number one on Google for their own company name!
So what is a an effective keyword or search term?
An effective keyword or phrase is one that is a popularly searched for by Internet users. There is no set value or limit above which all keywords can be deemed effective. The number of relevant searches per month varies by industry. In the travel industry, searches for certain phrases can be carried out by the tens of thousands per month only in the UK. By the same token, certain industries might consider ten or twenty searches per month to be effective. The important thing to remember when qualifying a search term’s effectiveness is that it should be searched for by your target market, and is more popular than similar related terms.
e.g. “search engine optimization” is searched for by over 15,000 visitors on the Overture network each month. Whereas “search engine optimizer” is searched for by only 200-300 visitors. Obviously, the former is the more effective search term in this case, and should be what an SEO company optimises its pages for.
Checking whether your selected keywords are effective
Google offers a very useful keyword tool inside AdWords to help you select the most effective keywords for your campaign, which would ensure maximum click-throughs and traffic for your site. The AdWords Keyword Planner allows you to enter a series of search terms, and then produces a comprehensive list of similar words and more focused search terms that you could use to expand or focus your targets.
How to optimise web pages for search engines
Optimising web pages for search engines and directories is not very different than developing web pages for human visitors. The main objectives remain the same – clean design, easy navigation and good content. In fact, when search engines rank pages they try to follow the same system of evaluations as most online searchers would.
Optimising ordinary HTML pages
HTML pages consist of two main section, a header and a body. Good search engine optimisation involves optimising both the header and the body for search engine spiders and human editors.
Optimising the HTML header
The header is the section that lies between the <HEAD> and </HEAD> tags. For search engine optimisation purposes, the three main components of the header that need optimisation are:
- TITLE: Lies between the <TITLE> and </TITLE> tags. Should provide a brief descriptive title for the page. No more than 60 characters.
- DESCRIPTION metatag: Should provide a 2-3 line objective description of the page. No more than 250 characters.
- KEYWORDS metatag: A list of comma-separated keywords. Very few search engines pay any attention to this tag nowadays.
Optimising the HTML body
The body is the part of the HTML page that lies between the <BODY> and </BODY> tags. This is the most important part of the web page, in that it is the part that is immediately visible to your visitors and hence is also the part that search engines pay most importance to when ranking your site. The main components of the body that count towards search engine ranking are:
- Text: The visible text on your web page is the single most important factor for search engine optimisation. Special weight is given to formatted text, such as headings, bold text, bulleted text and text contained in links.
- Internal links: The internal links connecting various pages in your website are important for both search engine spiders and visitors to navigate through your site. Links must be easily accessible and intuitive to follow.
External links and page popularity
Google and many other search engines measure the importance of a web page by the number of external sites that link to it, the number of visitors that click through to it and the time they spend on your site.

How to build links
Link building is one of the most challenging parts of search engine optimisation. Google pioneered the concept of determining the importance of a website from the number of external web pages that link to it. Nowadays many other search engines pay a degree of importance to the number of inbound links to your web pages. What makes link development difficult is the fact that you have little, if any control over it.
Good links and bad links
Not all inbound links are equally important. Links from websites that themselves have many inbound links, i.e. more ‘important’ websites, are considered more valuable than links from sites with few inbound links of their own. However, all inbound links are good. Care should be taken when joining link farms and other such schemes which require you to link back to them. You are never penalized by search engines for any inbound links, but can be penalized by search engines, and even considered to be a spam site if you have too many irrelevant outbound links from your websites to other sites that are known by the search engines to be spammy.
Links from online directories
The Yahoo! directory and dmoz (Open Directory Project) are the web’s leading directories for information. Getting your site listed on both of them is important as they both serve as very reliable points for other search engine spiders to find your site and crawl through it. Links from Yahoo! and dmoz are also important from a link building perspective as they both provide links to your site from a very highly ranked website.
In addition to Yahoo! and dmoz, you should also get your site listed on many other online directories as well as directories that provide information specific to your business and industry.
Links from related websites
Industry associations, partner companies, other companies in the same field that are not direct competitors, and websites providing information relating to your business and industry are all viable options to approach for links to your website. In these cases you could also provide links back to their website from yours as a courtesy, without worrying about being penalized by search engines, since these links would, in all probability be relevant.
What is Google Webmaster Tools?
Google Webmaster Tools, formerly known as Google Sitemaps, allows webmasters to authenticate ownership of their site and then manage certain aspects of their site’s listings on Google Search.
Webmasters can also add XML sitemaps / feeds of their website layout. This XML sitemap is submitted directly to Google, and is an efficient way to help Google spider and index large websites that might be hard to navigate.
Google Webmaster Tools can be used to inform the search engine spider of the addition of new web pages or updates on a website. The spider accordingly crawls the site and updates its index to reflect the latest changes on the site on its search results.
Who should use Google Webmaster Tools?
All webmasters who would like to improve their ranking on Google and reflect the latest version of their site on the search engine results pages should use Google Webmaster Tools.
Since May 2006 the tool includes a range of additional features such as crawl stats, query stats and page analysis, which make it very useful for search engine optimisation. Features of the tool inclue:
- Web Crawl: Identifies HTTP errors, broken links, unreachable URLs and restricted URLs
- Mobile Web: Identifies CHTML, WML and XHTML crawl errors that might affect how your website is crawled and viewed by Google Mobile
- Indexing Tools: Includes robots.txt analysis and preferred domain setting for sites with multiple domains
- Query Stats: Lists the top search queries and top search queries that are clicked to access your website
- Page Analysis: Provides a review of the keyword content of your site and links to your site as seen by the Google spider.
How much does it cost?
The Webmaster Tools service is absolutely free for anyone to use, so long as they have a Google account and can verify ownership of the site.
