Seo:How Search Engines Work

Tuesday, July 1st, 2008

Search engines come in two varieties, human-edited and spider indexed. The two major human-edited search engines (or directories as they are properly called) are the Open Directory Project (dmoz.org) and Yahoo. Search engine optimization is lost on the human-edited directories. Because humans will write your title and description for your site when they place it in their directories, using both objective and subjective methods, you have no control in the SEO-world over how your website will rank in these directories.

In both DMOZ and Yahoo, you can suggest a title and description, but most often your words will be rewritten by an editor and placed in their directories according to criteria of which you will not be privy to knowing. One of the big differences between DMOZ and Yahoo is that DMOZ is free and Yahoo is a paid inclusion. With both search directories there is the possibility of not being included, but as stated before DMOZ is free and with Yahoo, if you are not included, no refund will be given.

The only types of search engine in which you have some control are the search engines, which use spiders (sometimes called robots) to read, index and rank your site. The robots (and this is plural because some search engines like Google have several) are basically software applications that travel the Internet by following links and finding websites to read and add to their databases. These robots will travel to your website if you submit your site directly to them (hand-submit) or indirectly submit (through another software submission service or application) or fail to submit (they will follow incoming links to your sites also).

Once the robot finds your site and indexes it, it will move along to other sites from your outbound links. When you site is indexed, then another process takes place and this is the process of determining your ranking for specific keyword or key-phrase searches performed upon the search engine. All of the major search engines that use robots to index websites also use complicated algorithms for determining the page rank of your site. The search engine algorithm software looks at the title and description of the website along with keyword density and prominence to name a few to see which keyword or phrase your site is optimized for (if any). Certain weight is given for each of these components and the page is ranked accordingly.

The advantages of the spider-driven search engines over the directories are that first, search engine robots will continue to index your site on a regular basis whereas the directories basically will stick with the same title and description for the life of the website. Second, a webmaster or SEO professional has control over the optimization process in relation to the search engines, whereas in the directories, optimization is mostly irrelevant. Third, the volume (and popularity) of people using the search engines far outweighs the volume using the search directories. This means that yes, the major search directories are important places to submit your website to, but the major search engines are an absolute necessity.

How Google Data Centers Work

Friday, June 20th, 2008

If you didn’t already know Google has many data centers that run their index at any given time. They use different data centers to show different results. Some one on the East coast might see different results than someone on the West coast. Even using the next button on Google might take you to a different data center. Google decides what data center provides what result at any given time. If someone is aware of the different Google data centers IP address’s then they can poll each data center separately.

With the upcoming Big Daddy update Google has said that they are targeting these types of algorithmic changes:

* Canonicalization - How the engine decides what url’s reside in the engine.

* 302 redirects - Some developers have tried to spam the engines by serving keyword rich pages.

* Duplicate Content - Would be the same information at different locations.

My printer will not print what should I do?

Friday, June 20th, 2008

If your printer isn’t printing and it’s a new printer you’ve just taken it out of the box, first of all, look if it’s plugged into the computer. If the printer is plugged into the computer, the next thing to check is if it’s got power - is it plugged into a power outlet? If those things are plugged in, check if the software is loaded so that your computer can recognize the printer. If the printer still doesn’t work, call the manufacturer or take it back to the store and switch it out. If it’s an old printer, look to see if there’s still ink in there. If the lights are flashing and it’s telling you to replace the ink, that’s what you have to do. If there’s still ink left in the printer and it’s not printing, chances are it’s time to get a new printer.

How Does PageRank Work in google?

Thursday, June 19th, 2008

1. PageRank is only one of numerous methods Google uses to determine a page’s relevance or importance.
2. Google interprets a link from page A to page B as a vote, by page A, for page B. Google looks not only at the sheer volume of votes; among 100 other aspects it also analyzes the page that casts the vote. However, these aspects don’t count, when PageRank is calculated.
3. PageRank is based on incoming links, but not just on the number of them - relevance and quality are important (in terms of the PageRank of sites, which link to a given site).
4. PR(A) = (1-d) + d(PR(t1)/C(t1) + … + PR(tn)/C(tn)). That’s the equation that calculates a page’s PageRank.
5. Not all links weight the same when it comes to PR.
6. If you had a web page with a PR8 and had 1 link on it, the site linked to would get a fair amount of PR value. But, if you had 100 links on that page, each individual link would only get a fraction of the value.
7. Bad incoming links don’t have impact on Page Rank.
8. Ranking popularity considers site age, backlink relevancy and backlink duration. PageRank doesn’t.
9. Content is not taken into account when PageRank is calculated.
10. PageRank does not rank web sites as a whole, but is determined for each page individually.
11. Each inbound link is important to the overall total. Except banned sites, which don’t count.
12. PageRank values don’t range from 0 to 10. PageRank is a floating-point number.
13. Each Page Rank level is progressively harder to reach. PageRank is believed to be calculated on a logarithmic scale.
14. Google calculates pages PRs permanently, but we see the update once every few months (Google Toolbar).
