To understand the complexity of seo you should already know that Google uses over 200 ranking factors in their algorithm to determine which of the pages is relevant and worth increasing in search rankings. In the following we will dedicate interesting articles to the main factors that are integrated in the Google algorithm.
1. Domain Age: In this video, Google’s Matt Cutts states that:
“The difference between a domain that’s six months old versus one year old is really not that big at all.”
In other words, they do use domain age. But it’s not that important.
2. Keyword Appears in Top Level Domain: Having a keyword in your domain name doesn’t give you the SEO boost that it used to. But it still acts as a relevancy signal.
3. Keyword As First Word in Domain: A domain that starts with their target keyword has an edge over sites that either don’t have that keyword in their domain (or have the keyword in the middle or end of their domain).
4. Domain registration length: A Google patent states:
“Valuable (legitimate) domains are often paid for several years in advance, while doorway (illegitimate) domains rarely are used for more than a year. Therefore, the date when a domain expires in the future can be used as a factor in predicting the legitimacy of a domain.”
5. Keyword in Subdomain: Moz’s expert panel agrees that a keyword appearing in the subdomain can boost rankings.
6. Domain History: A site with volatile ownership or several drops may tell Google to “reset” the site’s history, negating links pointing to the domain. Or, in certain cases, a penalized domain may carry the penalty over to the new owner.
7. Exact Match Domain: Exact Match Domains may still give you slight edge. But if your EMD happens to be a low-quality site, it’s vulnerable to the EMD update.
8. Public vs. Private WhoIs: Private WhoIs information may be a sign of “something to hide”. Googler Matt Cutts is quoted as stating:
“…When I checked the whois on them, they all had “whois privacy protection service” on them. That’s relatively unusual. …Having whois privacy turned on isn’t automatically bad, but once you get several of these factors all together, you’re often talking about a very different type of webmaster than the fellow who just has a single site or so.”
9. Penalized WhoIs Owner: If Google identifies a particular person as a spammer it makes sense that they would scrutinize other sites owned by that person.
10. Country TLD extension: Having a Country Code Top Level Domain (.cn, .pt, .ca) can help the site rank for that particular country… but it can limit the site’s ability to rank globally.
