Links externos (inbound links)

Los links externos hacia tu site (inbound links) son muy importantes para google. Estos son links desde paginas externas que linkan hacia tu site. Estos pueden traer visitantes a tu web y cuando estos links son basados en el mérito y puestos libremente, les dan señales a google que tu web es importante.

Otras señales como la relevancia del contexto o contenido, o la posición geográfica, como muchos sabeis, dan mas importancia a estos links externos y por tanto afectan al PageRank, uno de los muchos factores que afectan al algoritmo de google. Estos links normalmente vienen de forma natural si tienes contenido de calidad.

Como afectan los links

Imaginemos que tengo un portal con un contenido relevante. Entonces recibirá varios links desde otras webs. Que links son más relevantes? La imagen siguiente lo explica claramente.

Inbound links are links from pages on external sites linking back to your site. Inbound links can bring new users to your site, and when the links are merit-based and freely-volunteered as an editorial choice, they're also one of the positive signals to Google about your site's importance. Other signals include things like our analysis of your site's content, its relevance to a geographic location, etc. As many of you know, relevant, quality inbound links can affect your PageRank (one of many factors in our ranking algorithm). And quality links often come naturally to sites with compelling content or offering a unique service.

How do these signals factor into ranking?

Let's say I have a site, example.com, that offers users a variety of unique website templates and design tips. One of the strongest ranking factors is my site's content. Additionally, perhaps my site is also linked from three sources -- however, one inbound link is from a spammy site. As far as Google is concerned, we want only the two quality inbound links to contribute to the PageRank signal in our ranking.

Given the user's query, over 200 signals (including the analysis of the site's content and inbound links as mentioned above) are applied to return the most relevant results to the user.




So how can you engage more users and potentially increase merit-based inbound links?

Many webmasters have written about their success in growing their audience. We've compiled several ideas and resources that can improve the web for all users.

Create unique and compelling content on your site and the web in general
Start a blog: make videos, do original research, and post interesting stuff on a regular basis. If you're passionate about your site's topic, there are lots of great avenues to engage more users.

If you're interested in blogging, see our Help Center for specific tips for bloggers.

Teach readers new things, uncover new news, be entertaining or insightful, show your expertise, interview different personalities in your industry and highlight their interesting side. Make your site worthwhile.

Participate thoughtfully in blogs and user reviews related to your topic of interest. Offer your knowledgeable perspective to the community.

Provide a useful product or service. If visitors to your site get value from what you provide, they're more likely to link to you.
For more actionable ideas, see one of my favorite interviews with Matt Cutts for no-cost tips to help increase your traffic. It's a great primer for webmasters. (Even before this post, I forwarded the URL to many of my friends. :)
Pursue business development opportunities
Use Webmaster Tools for "Links > Pages with external links" to learn about others interested in your site. Expand the web community by figuring out who links to you and how they're linking. You may have new audiences or demographics you didn't realize were interested in your niche. For instance, if example.com noticed external links coming from art schools, they may start to engage with the art community -- receiving new feedback and promoting their site and ideas.

Of course, be responsible when pursuing possible opportunities in this space. Don't engage in mass link-begging; no one likes form letters, and few webmasters of quality sites are likely to respond positively to such solicitations.

The main takeaway is that many of the business development techniques that are successful in human relationships can also be reflected online for your site.
