As the cost of paid search campaigns steadily rises, natural search programs provide
lower cost-per-click than paid search programs, affording them the second highest
returns of any marketing strategy.
Spend on search engine optimization (SEO) will grow at a compound
annual growth rate of 15% over the next 3 years to $5.1 billion by the end
of 2014, according to Forrester Research1. Why? Having mastered paid
search initiatives, online marketers are strategically increasing their
SEO budgets, sharpening their focus on optimizing traffic from natural
search to generate more targeted clicks at a much lower cost. This SEO
whitepaper covers four fundamentals for optimizing your site for web
search engines, along with several techniques for measuring the ROI of
your efforts, so that you too can start taking your natural Website traffic
to a new level.
SEO: TRUSTED, EFFECTIVE, LOW-COST
Optimizing your Website’s content and architecture for the major web search engines, such
as Google, Yahoo!, and Bing, is no longer optional for operating a successful web property.
Although driving traffic and more qualified customers from natural search is mission
critical – impacting up to half or more of a Website’s total traffic – many companies have not
yet implemented what are known to be the fundamentals of search engine optimization (SEO).
Why should SEO matter to your online business strategy – and your customers? The
compelling statistics below make the case.
HIGH RANKINGS, HIGH TRUST
With more than 100 billion searches each month2, people have come to rely on web search
engines as trusted sources of information. Experience has taught them that the highest
ranking links provide the most relevant results for their needs, increasing the number of
searchers who never look beyond the first one or two results3.

1. COMPELLING WEB CONTENT – THINK OF YOUR AUDIENCE
As with any online user experience, it is important to target your audience and keep your
message customized to their needs. Whether they are shopping for products, reading
articles or blogs, or watching online video, your customers expect content that is relevant to
them at that moment. And, believe it or not, web search engines have done us all a favor by
recognizing and rewarding sites that help Internet searchers quickly find the most relevant
information they desire.
WHO YOUR CUSTOMERS TRUST Not surprisingly then, some of the most important practices that can improve your SEO
performance are key activities around content creation and presentation.

and reviews – because they represent a comprehensive and robust experience for human

indexed and seen by spiders.
ADD THE VOICE OF YOUR CUSTOMERS
Expanding on the point above, not only do search engines like user-generated content (such as
reviews, recommendations, and customer ratings) for its depth and freshness, but consumers
like this content too, because they tend to trust the opinions of other people like them6.

Dedicating time and resources to constructing meaningful title tags for each page
of your Website is one of the most important SEO practices you can implement.
SKIP THE TRICKS
Web search engines are sophisticated enough to detect “black hat” schemes. One such
unsavory trick is “cloaking,” which involves making spider-centric text invisible to humans
by using a white font on a white background.
By writing more readable, succinct, and persuasive copy, and surrounding site visitors
with relevant and meaningful content, you will soon find not only higher natural rankings
coming your way, but also you will convert more browsers to paying customers.
2. METADATA AND URL STRUCTURE – FIRST IMPRESSIONS COUNT
It seems simple enough – if you make a good first impression on web searchers, more of
them will click through to your Website.
Within the architecture of your Website, you get three chances to immediately connect
with searchers and spiders and give them insight into what they can expect to see when
they click through on your search result. The better you prepare these three “signals,” the
greater your search credibility will be.
Search engines recognize that page titles, or metadata title tags, are what people see first, so
they put more weight on them in their ranking algorithms. And the more human-readable
your titles are in natural search results, the more you increase the likelihood of click-
through. Dedicating time and resources to constructing meaningful title tags for each page
of your Website is one of the most important SEO practices you can implement.
Title Tags: Construct Meaningful and Accurate Descriptions
Bon appétit! A search on Google for “lemon cake” displays a link to Foodnetwork.com as the first result. The page
content doesn’t disappoint when you click through to a targeted landing page with not only a lemon cake recipe,
but also related recipes, user comments, videos, and links to purchase just the right type of cake pan.
ENDECA TECHNOLOGIES | 4 SEO Fundamentals to Boost Natural Search Traffic 5
When developing your title tags, follow these guidelines that are known to help SEO rankings:
> Assign a unique title to each Webpage (URL) on your site.
> Make sure the title gives an accurate description of page content and contains your
> Be brief. Most web search engines will cut your titles off after 80 characters, so try to
keep them four to five words.
META DESCRIPTION TAGS
These tags do not appear on your actual Webpage. Instead, they are short, 155-character
descriptions that display on the search results page (SERP). Description tags are critical
for enticing visitors because they tell people what to expect when they click through to your
Website. However, keep in mind that they do not impact your SERP rankings for particular
When developing meta description tags, follow these guidelines:
> Each Webpage should have a unique and different description. Don’t just copy and
paste descriptions that generalize your Website’s content.
> Re-use keywords from your title tags; this reinforces those words as relevant terms.
> Keep it short. Search engines such as Google cut off descriptions that are longer than
two sentences (typically 25-30 words).
Meta Description Tags: Tell People What to Expect
WYSIWYG What you see is what you get when you click through to the lemon cake landing page on Foodnetwork.com.
The brief yet welcoming meta description invites me to give the recipe a try.
Like site content, title tags, and meta description tags, how you construct your URLs is
important to both the search engines and your customers.
When choosing a format for your dynamic URLs, follow these simple guidelines:
ENDECA TECHNOLOGIES | 4 SEO Fundamentals to Boost Natural Search Traffic 6
> Ensure that each Webpage corresponds to exactly one URL; multiple URLs pointing
to the same page may be interpreted by search engines as an attempt to artificially
increase the size of your Website. This issue is of particular concern for dynamic sites,
which provide an excellent end-user experience but may result in separate URLs for
every possible navigation path (such as “Blue Sweater + Cashmere + $100-$200” and
“Cashmere + $100-$200 + Blue Sweater”). Consolidate duplicate dynamic URLs into
a single, canonical URL that corresponds to the Webpage.
> Use no more than three dynamic parameters. Search engines can interpret these
highly parameterized URLs, but they are hard for humans to read and remember.
> Include keywords that are consistent with the content, title tag, and meta description
tag of the Webpage.
URL Structure: One-to-One Correspondence
/Exactly what you need, right here/ Armstrong Commercial Flooring helps tell customers searching for a very
particular tile – blue biobased tile, to be exact – by signaling to them what they’ve find when they click with a clean
URL structure: /biobased-tile/blue.
A final word on metadata: Content, URLs, and description tags should be optimized for
three or four keywords or keyword pairs (preferably three; four only on pages deep in
the hierarchy) in order to achieve optimal rankings. Be aware that search engines do not
process information like humans so if they see the same keyword in multiple places it tells
them “this site must be about <insert keyword>.”
Tuning metadata tags and URL structure is critical to building strong SEO, but can be
extremely time-consuming if done manually. Use automated utilities wherever possible to
save time and get consistent results.

3. TARGETED LANDING PAGES – GIVE A WARM WELCOME
With more natural site traffic, you have an opportunity to offer a personal welcome to
visitors as they arrive on your site. The challenge is that many traditional Websites are
built on a taxonomy that drills into category/sub-category pages, but does not go further.
On these sites, few pages are built from the intersection of product attributes that people
are searching for on the web, limiting the entry points on a site for visitors. For example,
you might have a page that displays products at the intersection of “Brand” and “Category”
but not necessarily for the complete criteria of a visitor’s search, which would be at the
intersection of “Gucci-Shirts-Blue-Formal-Button-Down-Collar.”

Source: Chris Anderson, The Long Tail: Why the Future of Business is Selling Less of More
These “long-tail” queries7, usually about 2-4 words long, are particularly high value because
they contain more information about exactly what the visitor is looking for. Think of these
targeted landing pages as “side doors” to your Website – pages within your site that search
engines (as well as other links such as blog entries and Twitter posts) will find, bypassing
the home page of your Website for more relevant content. The faster these side doors can
make visitors feel like they are at the right place for their information needs, the more likely
it is that the visitor will convert. And not only do these keywords contain more specific
information about the intent of the searcher, but they are also not as heavily contested by
pay-per-click efforts, so you have a better chance of grabbing a top ranking. Below are some
tips for creating these side doors.
BREAK OUT YOUR PRODUCT ATTRIBUTES
It’s not enough to have product attributes buried in your product details pages. Wherever
you can, break out product attributes as metadata and create unique pages at all the
intersections of these attributes in order to highlight the numerous products that share
those attributes. As a result, your pages will rank highly for the very specific, long-tail
searches that include these attributes. While a tedious manual process, this can be done in
an automated way with some search engine technologies.
ENDECA TECHNOLOGIES | 4 SEO Fundamentals to Boost Natural Search Traffic 8
Know your top 100 to 500 keywords and measure how your results-page rankings
change over the course of your initiative. If you’ve implemented targeted landing
pages, make sure to track how much traffic comes through long-tail “side doors.”
DROP SOME BREADCRUMBS
As outlined in the previous section, title tags are crucial to making a good first impression on
new visitors from natural search. By adding breadcrumbs that show the product attributes
represented on all of your pages, you can use these to automatically populate page headers
and title tags throughout your site, ensuring that even long-tail pages are keyword-rich.
Targeted landing pages improve engagement and conversion because they provide more
relevant content specific for any given search, whether from a web or on-site search engine.
4. SITE MAPS – PREVENT SPIDERS FROM OFF-ROADING
Now that you’ve done the essential on-site work, it’s time to put your site “on the map” for
even greater visibility. It is important to know that search engine spiders take their time
recognizing pages – particularly when encountering new content. And, they may initially
only crawl one or two levels deep for fear of getting “lost,” indexing only part of your site
and leaving thousands of pages out of search engine results pages.
A sitemap acts as a guide that leads spiders to important content within your Website,
ABOVE THE CRAWL OF DUTY encouraging them to crawl deeper, index more pages, and expose more of your content to
searchers. When optimized properly, a sitemap can also help search engines by including

CRAWL OF DUTY, APRIL 2009 landing pages. A good sitemap generator should eliminate any duplicate URLs too, which
otherwise will dilute your rankings.
DON’T FORGET TO INDEX DYNAMIC PAGES
If you have billions of dynamic pages created by an on-site search engine, you need to
indicate to spiders which intersections of product attributes are the most valuable so they
can prioritize their indexing. You probably have a map for your static pages – don’t forget
about the dynamic ones.
REDIRECT USERS TO NEWER PAGES
As you update products and content on your Website, preserve rankings and inbound links
by implementing 301 redirects from old pages to new pages. These redirects help spiders
log changes of address, signaling that there has been a permanent move and that all visitors
should be forwarded to the new URL.
While search engines will (eventually) find your sitemap on their own, it is a good idea
to push an XML and HTML sitemap to the major web search engines on a regular basis,
ensuring accurate and more frequent indexing as your site is updated.

ROI FOR SEO – HOW MUCH BANG FOR YOUR BUCK
Just by getting started with the four SEO fundamentals outlined above, you will see an
automatic increase in the amount of natural search traffic that comes to your site. But, if
you own the SEO strategy at your company, it’s important to understand what it took to
climb higher on the search results page and how to find ways to climb even higher.
Business owners who contributed budget to optimize your Website for natural search will
want to know that they are getting a good return on their investment. Thankfully, there are

The Longtail: Why the Future of Business is Selling Less of More, Chris Anderson, New York: Hyperion, 2006.
Although the Long Tail theory has come under fire in the past few years, when it comes to web search queries the theory holds
strong. Below are a few sources pointing to statistics that long tail traffic regularly produces over half of search traffic to large
sites: Wired Blog Network, “Google’s Long Tail”, Feb 12, 2005, Read Write Web, “Google’s Udi Manber”, June 21, 2007, Hitwise
Intelligence, “Sizing Up the Long Tail of Search”, Nov 2008.
Making balanced recommendations on how to invest in the long tail, Anita Elberse in her article entitled “Should You Invest
in the Long Tail” (Harvard Business Review, July-August 2008, page 98) advises online retailers to not put all their eggs in the
“long tail” basket, and to still acquire and manage customer by using their most popular products. However, “if the goal is to
cater to your heavy customers, broaden your assortment with more niche products. [Her] research shoes that even when online
assortments of [products] are enormous, and thus even the most frequent customers could easily satisfy their appetites with
products in the top decile, those customer are disproportionately active in the tail. They want a wide assortment, so offering one
helps attract and retain them.”
