2 types of links in the SERP
SERP – Search Engine Results Page
- Sponsored – advertised ranked by how much money is paid for targeted keywords.
- Organic – indexed by web bot based on content, keyword relevance and popularity. People trust the free listings more than sponsored results. Learned that these are more accurate. Free results create a much higher click through rate.
Organic indexing uses algorithmic technology in the form of web bots or web crawlers. Crawler software moves site to site indexing content to be listed in the SERP.
Crawler based technology
- Spider or crawler visits the site and indexes content, then moves on to another site through the sites links
- Spider delivers the info it sees to the data base
- Data base ranks info according to programming (each company different)
- Search algorithms are used to match user query to ranked data
- List, tree, sql (sequel), informed (most are a combo and prop.)
- Then results are ranked for user (order of the results)
Each engine uses different programming for their spider. That is why the same search on different engines produces different results.
Crawlers Index Conent in Several Ways
- Page Content – prominence of content (domain name, title, headline, top of page content)
- Frequency & Relavancy of keywords
- Popularity – inbound links from other popular sites (like sitting with the popular kids in school makes you more popular) as well as click through percentage (how many users actually click on the link in the index. Off page factors (becoming more popular for search technology because the developer does not have as much influence. Search engines trying to counter web optimizers.
No two search engines conduct cfp indexing the same way
Popularity – Ranking
Page rank is an algorithmic process invented by Larry Page that judges the popularity of of a page comparatively. Higher page rank increases prominence of listing within the SERP. The higher the page rank of the site linking to you the more valuable.
- Page Rank uses a logarithmic scale from 0 – 10 1 – 2 is easier than 2 – 3
- Google looks at the number of links that points to the page and their rank.
- Some links carry more weight and importance than others
- Links from pages that have less links are better than pages that have more
- Pages on your site pass page rank to one another as well. (important because of web wide tasking)
- Trusted sites such as cnn and others that you cannot control, that have your links carry more value
- Linking within social media networks will also improve popularity
Choosing Targeted Keywords:
Keywords are the root of all success with search engines
- Start with a list of all possible key words or key phrases
- Access Server Log Files – Log files contain keyword search info
- Use host provided stat analysis such as urchin, awstats, webtrends and analytics
- Use Wordtracker
- Ask customers, clients & associates what keywords they would use to find the site
- Look at the competition
- Scan through list and find common misspellings and add to list (estimated that 25% of all queries are misspelled)
- Add both singular and plural versions of terms
- Don’t worry about case, SE not case sensitive
- Keyword phrases are more effective – users use more phrase based search
- Use questions within content to match user query
- Be as specific as possible – ex “European Bike Tours” instead of “bike tours”
- Be careful of using trademarked phrases such as ipod, itunes etc
Domain Names
How domain names affect SE Placement:
- Google likes keywords in anchor text pointing to your site
- SE’s assume domain names are relevant to keywords
- Improves chances of humans clicking on your links
- Use hyphen between the words to make it easier for the SE and user
Customer friendly domains:
- Short
- Memorable
- Easy to type
- .com
SE Friendly:
- Long
- Keyword Rich
- .biz, .net & country specific
Excluding files from search indexing
Place a text file at the root named robots.txt – used to inform search agent of files that should not be indexed.
User-agent: * (used to get the bots attention)
Disallow: /images/
Disallow:/ *.jpg
Disallow:/ *.gif
Disallow:/ *.swf
Also disallow password protected and other secure areas that would block indexing.
Also place meta data in head of document to guide search engine:
ex – <meta name=”robots” content=”noindex, nofollow” />
