Search Engine Factors (SEO)
I inspired myself to write about this list of 10 search engine factors (SEO), that is to say, those what search engines (SE’s here on) consider to make its mathematical calculations and give as result the ranking/position of every website in its listings. Obviously there are confidential data that these corporations are not going to disclose never for free competition and privacy reasons; this besides the fact that they’ve been modifying them (the importance of each factor) because of bad use that users/webmasters did in the course of the last years.
It’s worth mentioning that these factors are under my personal appreciation, which I have experienced and may change in the course of time, this doesn’t mean they are completely true. I am going to subtitle/classify all factors into 2 groups: primary and secondary.
Primary Factors
1. Website Title: it’s no one secret to anybody that SE consider this factor as very important, specially Yahoo and Bing. The title is all content that is into tags of your HTML code, within it should contain your most important keyword. Taking as sample that mine would be “Texas Real Estate”, a title could be..
<title>Texas Real Estate | Other keywords here </title>
2. Incoming Backlinks: this is the heavyweight factor to Google than the rest of SE’s. Quality more that quantity links from the different websites that “point to” or “link to” your site, is what Google considers most important. What do I mean by quality? For example, a link from New York Times or Washington Post is more important that one from Peter Smith blog; and about quantity? the more links better…
The conditions that a optimum backlink needs to have are:
- Be a “dofollow” link, i.e. that the link doesn’t have the HTML tag rel=”nofollow”
- Have an adequate structure, i.e. the main or secondary keyword contained into that link.
For example, an adequate link for using to my blog (and I’d like to be backlinked), using the keyword “e-commerce blog” would be:
<a href="http://ovalencia.com/en/">E-commerce Blog</a>
3. Headers: they’re the famous <H1> and <H2> HTML tags, and have as a main function to stick out subtitles or keywords relevant to the paragraph that comes after. It’s not known if the SE’s give more importance to, whether H1 or H2, is a long discussion topic; I guess nobody can asseverate respecting to SEO but approximations about how it does work.
Into these headers is advisable also to include the main keywords of your website, the same that should be before the main content section or paragraph, as follows:
<H1>Texas Real Estate</H1>
<H2>Texas Apartments</H2> or <H2>Texas Houses</H2>

1) Physical Products Sale: consists on commercialization of real products (tangible), through online shopping carts, an intermediary or similar.
