QUALITY OF A WEB-SITEhttp://googlewebmastercentral.blogspot.com/
“More guidance on building high-quality sites”Friday, May 06, 2011 at 11:22 AM

SCENARIO
SITE-TRUST Would you trust the information presented in this article?
10
#1 : SEMANTIC WEB FOR WEBMASTERS
Sem WEB is a “web of data”
EXAMPLE: Dublin Core metadata record can describe physical resources such as books, digital materials such as video, sound, image, or text files.
11
#2 : SEMANTIC WEB & SEARCH ENGINES
1) Related content into SERPS2) No exact keyword matching!
12
SEMANTIC WEB & SEARCH ENGINES
Google tries to “guess” relevancy of documents using some semantic features
13
LATENT INDEX SEMANTIC
From exact KW matchings to semantic domains
Semantic Domain
What this page is really about ?
Find related terms to a main keyword
14
FACING BLACK BOX
Semantics → give real sense to your contentsExpose relevant data (i.e. price and essential
features of products you sell)
15
APPROACHES
Semantics → spread keyword on page using contextual associations (i.e. cheap car is often used car)
Expose relevant data → integrate HTML with microformats
16
“SEMANTIC” BACKLINKS
SEO = just “inflate” your PR → reducted impact, narrow vision
Automated backlinks (little blogs, random forums, paid links, …)
Semantic-backlinks example:
Comment a site / Be cited by a site pertinent and contextual
FAST & FAST & BADBAD
SLOW & SLOW & GOODGOOD
17
TIPICAL PROBLEMS• Spam• Similar Articles• Content Farms• Duplicate Contents...
18
TIPICAL PROBLEMS• ...Well-knows competitors take the lion's share• → Many researches with:
– Bad Precision – Bad Recall
19
Query entity detection
Search engine receives a search query, determines whether the received search query includes an entity name, and determines whether the entity name is associated with a common word or phrase. Generate a link to a rewritten query or include a restrict identifier associated with the entity name (US Patent 7,536,382)
http://www.makebeliefscomix.com/Comix/
GOOGLE PATENT
20
DON'T REPEAThttp://mdrseo.com
– “echo back” effect - i.e. similar low-quality contents about same topic:
I evaluate X about Y
We think X about Y
I (!) suppose X about Y
WE ARE SURE: X=Y
21
SEO
• Documents• Links
22
SEO → SEO++
• Documents → data, things, entities• Links → “relationships”
page
entity
sem-rel
23
THE PRICE TO PAY
• Extend keyword using semantic domains
– Microformats → little-impact HTML changes
24
WEB 3.0• RDF = “general method for
conceptual description of information that is implemented in web resources”
• µF = re-use existing HTML/XHTML tags to convey meta-data and other attributes in web pages and/or RSS
25
REMARKS
– QUALITY ≈ TRUST concept– Latent Index Semantic– Relevant details to search engines:
• Microformats– Avoid “echo back” effects
26
my-site.com/index.php?sect=4&p=2
SEMANTIC URL = “human-readable”
27
my-site.com/index.php?sect=4&p=2
e-commerce.com/buy-php-mysql-hosting buythis.net/hosting/cheap
SEMANTIC URL = “human-readable”
28
SEMANTIC URL = “human-readable” easily remembered; navigational structure; intuitively manipulated; more durable; more bookmarked; may improve security!
29
REMARKS GOOGLE DOESN'T USE EXACT MATCHING
Example: buyshoes.com/cheap-buy/low-cost-shoes KEYWORD STUFFING
IS NOT USEFUL FOR USERS → NOT USEFUL FOR SEARCH ENGINES
30
titledescriptionURL
URLs ARE NOT ALL...
“When searchers scan through search engine listings what usually they read?”
43%: descriptions 30%: titles 21%: URLs
http://yourseoplan.com
31
OPTIMIZING TITLE/DESCRIPTION
Semantically related means:
Taking into account THE MOST STRICTLY LINKED UP terms
32
INTRODUCING: LONG TAIL
Searchers often use too generic stems (i.e. hostel, site-builder)
In others cases people tends to be more specific (i.e. london cheap hostels, free site-builder mac)
33
THE LONG TAILLong tail addresses usually many specifical keywords (niches)

51
WHY SHOULD GR BE USEFUL FOR SEO?
• Universal Product Catalogue
• SERP quality improvement
• Well-known format
52
hReview is a microformat for publishing reviews of books, music, films, restaurants, businesses, holidays, etc.[1] using (X)HTML on web pages
It uses HTML classes and rel attributes

hReview
http://wordpress.org/extend/plugins/wp-customer-reviews/
53
hReview + Google
• Properties– fn (formatted name)– Reviewer (GameSpot)– Date (Nov 3, 2009)– summary– description– rating ( )
• Individual Review• Review-aggregate
54
hReview into HTML markup
By default, Google assumes that your site uses a 5-point scale, where 5 is the best possible rating and 1
is the worst.
55
Review-aggregate: example
http://www.google.com/webmasters/tools/richsnippets
56
Another example: Google Recipes
57
WHY SHOULD hReview BE USEFUL FOR SEO?
• Increase word-of-mouth (visits)
• SERP quality improvement
• Well-known format

THE LAND OF THE UNICORN...?
If everyone would subscribe to such a system and create good metadata for the purposes of describing their goods, services and information →
• it would be a trivial matter to search the Internet for highly qualified, context-sensitive results
60
CRITICISM: “metacrap”
http://www.well.com/~doctorow/metacrap.htm
• There's more than one way to describe something• Dishonesty: emphasize my high-scoring axes && de-
emphasize my low-scoring axes
“A leopard can't change his spots”
61
FAQ
• Microformats “ignored” by Google?– Not Visible to users (i.e. display:none)– Wrong Sintax– Low Relevance– Crawler not yet updated – ...patience ;)
Mmm... no microformats shown in Google...???
62
4-STEP SEO++
• Semantic KW research• Semantic-URLs• GoodRelations for improving your e-
commerce site• Give user the chance to review/vote your
contents (software, services, … )
63
LOOKING AT THE FUTURE
• Naturally adapting semantics in Twitter (µBlogs)• LinkedData: "recommended best practice for
exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web”
• SPARQLE http://en.wikipedia.org/wiki/SPARQL
