One of the factors that affect the positioning of a website is the internal structure of the same. We will detail a guide to follow step by step, to obtain an excellent optimization on-page of our site: 1) keywords in the URL: containing the url keyword to optimize. (For example, if we want to optimize the keyword flower shop online in santiago and is our web site, the url of the page to optimize should be 2) keywords in the domain name: following the previous example, it would be better to hire the florist-online-in-santiago.com domain or floreriaonlineensantiago.com or have multiple domains pointing to the same site. (3) Key words in the Title tag of the page’s code: fundamental is that the title of the page contains the or key words that we’re optimizing. The same length should be between 10 and 60 characters long and should not contain special characters. (4) Keywords in the Description metatag of the code of the page: although it is estimated that Google ignores its content to index a site, it is the description that appears on our site in a search result. It should contain less than 200 characters. (5) Keywords in the Keywords metatag of the code on the page: it should contain less than 10 words, and each word must appear somewhere in the body of the web page, so that Google does not penalise us for irrelevance of the keyword. (6) Density of the keywords in the text on the page: between 5 and 20% (all key words / total words of the page). (7) Each word density key individually: between 1% and 6% (each keyword / total words of the page). (8) Keywords in H1, H2 and H3 tags: keywords should appear in the body of the page between those tags. (9) Source of keywords: in larger, bold, italic is another of the recommendations. (10) Prominence of keywords: how much further up in the contents of the web page appears, better. ((11) Key words in the tag alt of images 12) key words in links to other pages of the site (anchor text) 13) all internal links on the page should be valid: this tool can be used to check them: 14) Links to external sites: only have links to good external sites. Do not link to links-farms. (15) External Links have to be valid. (16) Less than 100 external links in total. (((17) Domain name extension: in order of most to least status for Google: .gov, .edu, .org, .com, .info 18) each page size: should not exceed 100 KB 19) frequent content updates: Google loves this. ((20) Age of the site: when more old best 21) age of page vs. age of the site: more new pages in sites more old, have a more rapid recognition by Google.
