3. SEO resource vs PPC resource Why SEO is more important • Q4 is coming; PPC ROI goes down, bids up, competition everywhere. • Direct-To-Merchant deals more difficult to land. • Google disabling “routing/jump” pages. Return of the Portal • Still use PPC, but reinvest spend on your brand. • Build portal, do it properly. • Free natural traffic is extra revenue. • Add to favourites, email capture. • Campaign deals, CPM/CPC hybrids. • Tangible asset.
4. Writing for Search Engines – On Page SEO Well crafted content is good for: • Human beings • Accessibility AND • Search Engines You don’t need to compromise. RELEVANCY RELEVANCY RELEVANCY
5. Body Text • The initial content, the first 2-3 paragraphs, is the MOST IMPORTANT. Especially the first 150-200 characters. • Keyword Phrases (used by your target user/market) presented consistently and logically throughout body text will boost rankings. • When possible, Keyword Phrases should be used at the start, or near to the start of paragraphs. • Ideal target is 200 – 300 words per page.
6. Things you may not know. • The Title tag has a stronger weight with regards to Googles ranking – BUT – Google will try to match keywords and phrases in the Title tag with links and text in the page. • Title tag should be varied to reflect each page. First 60 characters are the most important, title tag should be no longer than 15 words. • Keyword density of around 2-7% is recommended (won’t trip filters). KD = “Keyword Count” divided by “Total Words” x “100”. • Keyword frequency (repetition) of around 3-7 times per 100 words is recommended. • Keyword prominence – words at the beginning of a page, paragraph, header are assigned a greater value than those at middle or end. • Keyword proximity – the distance between 2 related terms, the shorter the difference the better the page will rank for that phrase.
7. Links and Attributes – Off Page SEO • Links are your currency on the web and are your net worth. • Not all links are equal, a reciprocated PR4 guest book link is not the same as an on topic PR4 link from an authority site. • Focusing on one aspect of a link (PR, anchor text, placement) neglects the understanding each link can have on your rankings.
8. Links and Attributes – Off Page SEO • Links have different qualities, weightings and attributes. • The weightings change making links worth more or less each update. • If you drop in rankings you may not have been penalised, just have less of the “in-currency”. • Important as you need to know what links to go after as they right links can take a long time.

One for your technical team. • MOD_REWRITE for Unix/Linux based systems. • ISAPI_REWRITE for Windows based systems. Check with your host if you are able to install these modules, if not, you will need to change hosts.
11. Robots.txt Robots.txt – A text file that you place on your server which instructs search engines spiders to NOT crawl a page on your site. Always use on the following pages: Pages under construction, CGI-BIN, Redundant information. Always use a robots.txt file even if its empty. Here is an example: User-agent: *
