Recientemente, alguien escribió un post en el foro, preguntando cuáles eran los factores mas importantes a tener en cuenta a la hora de seleccionar una agéncia de marketing online.
Se refería a temas SEO y SEM.
Hoy he estado leyendo un post (en inglés) que, entre otras cosas, presentava una série de preguntas clave a realizar a cada agencia de cara a poder realizar una buena selección.

También conocido como el protocolo de la exclusión de robots o protocolo de robots.txt es un método para evitar que ciertos bots que analizan los sitios webs u otros robots que investigan todo o una parte del acceso de un sitio web, público o privado. Los robots son de uso frecuente por los motores de búsqueda categorizar y los sitios webs del archivo, o por los webmasters para corregir su código fuente.
Un archivo robots.txt en un sitio web funcionará como una petición que especifica que determinados robots no hagan caso a archivos o directorios específicos en su búsqueda. Esto puede estar, por ejemplo, fuera de una preferencia por aislamiento de resultados del Búsqueda avanzada, o de la creencia que el contenido de los directorios seleccionados pudo ser engañoso o inaplicable a la clasificación del sitio en su totalidad, o fuera de un deseo que un uso funciona solamente encendido ciertos datos.
El protocolo, sin embargo, es puramente consultivo. Confía en la cooperación de los robots del sitio web, de modo que marca un área de un sitio fuera de los límites con robots.txt no garantice aislamiento. Algunos administradores de sitios web han intentado utilizar el archivo robots.txt para hacer de algunas secciones privadas de un sitio web invisibles al resto del mundo, pero el archivo está necesariamente disponible en forma pública y su contenido puede ser visto fácilmente por cualquier persona con un navegador web.
No hay cuerpo de los estándares o RFC oficial para el protocolo de robots.txt. Fue creado por consenso en junio de 1994 por los miembros de robots que enviaban la lista (robots-request@nexor.co.uk). La información que especifica las piezas que no deben ser alcanzadas se especifica en un archivo llamado robots.txt en el directorio a nivel superior del Web site. Los patrones de robots.txt son emparejados por comparaciones simples de la subsecuencia, así que el cuidado se debe tomar para cerciorarse de que los directorios de la concordancia con el modelo tienen “/” del final carácter añadido, si no todos los archivos con nombres comenzando con esa subsecuencia emparejarán, más bien que apenas ésos en el directorio previsto.
Ejemplos:
- Este ejemplo permite que todos los robots visiten todos los archivos que se encuentran almacenados en el código raíz de la página web porque el comodín “*” especifica todos los robots:
User-agent: * Disallow:Cabe destacar que el comodín (*) significa “ALL” o en lo sucesivo en español “TODOS”
- Este ejemplo les niega el acceso a todos los bots (implementando el comodin [*], en todos los archivos almacenados en el directorio raíz:
User-agent: * Disallow: /Cabe destacar que el comodín (/), le niega el acceso la entrada al bot.
- El siguiente es un ejemplo que dice todos los subdirectorios que incluyan el comodín (/), deben de ser bloqueadas solamente, y exceptúa a todos los demás archivos que no contienen un comodín, para su revisión:
User-agent: * Disallow: /cgi-bin/ Disallow: /images/ Disallow: /tmp/ Disallow: /private/
Os adjunto un resumen interesante de las Q&A del último PubCon. Como siempre… interesante.
Site Verification Files and Meta Tags
Several webmasters asked, “Is it necessary to keep the verification meta tag or HTML file in place to remain a verified owner in Webmaster Tools?” The answer is yes, you should keep your verification file or meta tag live to maintain your status as a verified owner. These verification codes are used to control who has access to the owner-specific tools for your site in Webmaster Tools. To ensure that only current owners of a site are verified, we periodically re-check to see if the verification code is in place, and if it is not, you will get unverified for that site. While we’re on the topic:
Site Verification Best Practices
If you have multiple people working on your site with Webmaster Tools, it’s a good idea to have each person verify the site with his or her own account, rather than using a shared login. That way, as people come and go, you can control the access appropriately by adding or removing verification files or meta tags for each account.
You may want to keep a list of these verification codes and which owner they are connected to, so you can easily control access later. If you lose track, you can always use the “Manage site verification” option in Webmaster Tools, which allows you to force all site owners to reverify their accounts.
Subdomains vs. Subdirectories
What’s the difference between using subdomains and subdirectories? When it comes to Google, there aren’t major differences between the two, so when you’re making that decision, do what works for you and your visitors. Following PubCon, our very own Matt Cutts outlined many of the key issues in a post on his personal blog. In addition to those considerations, if you use Webmaster Tools (which we hope you do!), keep in mind that you’ll automatically be verified for deeper subdirectories of any sites you’ve verified, but subdomains need to be verified separately.
Underscores vs. Dashes
Webmasters asked about the difference between how Google interprets underscores and dashes in URLs. In general, we break words on punctuation, so if you use punctuation as separators, you’re providing Google a useful signal for parsing your URLs. Currently, dashes in URLs are consistently treated as separators while underscores are not. Keep in mind our technology is constantly improving, so this distinction between underscores and dashes may decrease over time. Even without punctuation, there’s a good chance we’ll be able to figure out that bigleopard.html is about a “big leopard” and not a “bigle opard.” While using separators is a good practice, it’s likely unnecessary to place a high priority on changing your existing URLs just to convert underscores to dashes.
Keywords in URLs
We were also asked if it is useful to have relevant keywords in URLs. It’s always a good idea to be descriptive across your site, with titles, ALT attributes, and yes, even URLs, as they can be useful signals for users and search engines. This can be especially true with image files, which otherwise may not have any text for a search engine to consider. Imagine you’ve taken a picture of your cat asleep on the sofa. Your digital camera will likely name it something like IMG_2937.jpg. Not exactly the most descriptive name. So unless your cat really looks like an IMG_2937, consider changing the filename to something more relevant, like adorable-kitten.jpg. And, if you have a post about your favorite cat names, it’s much easier to guess that a URL ending in my-favorite-cat-names would be the relevant page, rather than a URL ending in postid=8652. For more information regarding issues with how Google understands your content, check out our new content analysis feature in Webmaster Tools, as well as our post on the URL suggestions feature of the new Google Toolbar.
Moving to a new IP address
We got a question about changing a site’s IP address, and provided a few steps you can take as a webmaster to make sure things go smoothly. Here’s what you can do:
Change the TTL (Time To Live) value of your DNS configuration to something short, like five minutes (300 seconds). This will tell web browsers to re-check the IP address for your site every five minutes.
Copy your content to the new hosting environment, and make sure it is live on the new IP address.
Change your DNS settings so your hostname points to the new IP address.
Check your logs to see when Googlebot starts crawling your site on the new IP address. To make sure it’s really Googlebot who’s visiting, you can verify Googlebot by following these instructions. You can then log into Webmaster Tools and monitor any crawl errors. Once Googlebot is happily crawling on the new IP address, you should be all set as far as Google is concerned.
To make sure everyone got the message of your move, you may want to keep an eye out for visits to your old IP address before shutting it down.
Proxies
A few webmasters were concerned that proxy services are being indexed with copies of their content. While it’s often possible to find duplicate copies of your content in our results if you look hard enough, the original source is most likely going to be ranked higher than a proxy copy. However, if you find this not to be the case, please drop us some URLs in the Webmaster Help Group. There are many Googlers including myself who monitor this group and escalate issues appropriately.
Ultimamente estamos deployando una estratégia de Adwords a nivel Europeo, y hemos detectado algunas diferéncias muy, muy relevantes.
Almenos, son diferéncias que de haberlas sabido… nos hubieran modificado algunas prioridades
De hecho, me quadran a la perfección con un cuadro que vi en algun site, con las previsiones de inversión en publicidad en toda la zona “Western Europe”.
Para que os hagais una idea… Francia era una de nuestras primeras prioridades… pero claro: Hemos podido comprobar (y coincide con estas previsiones) que es uno de los paises con mas competéncia !!! (a parte del todo poderoso uk, claro).
En fin: Una información muy interesante.
Si pretendeis entrar en Francia, UK y/o Alemania –> Guardaros un buen budget, o no hareis nada de nada.
Sin embargo… Italia, y otros paises menos “desarrollados” permiten inversiones mas controladas.
Espero que os sirva !!! (Ojala lo hubiera tenido yo antes)
Este post es solo para aquellos que les interese saber como Google tiene organizado uno de sus Datacenters (el que tienen en Oregon).
Se basa en 3 edificios, un espacio de parking bastante grande… y un dimensionamiento electrico (en cuanto a capacidad espectacular !!!).
El plano es originario de Harper’s Magazine. Me ha parecido interesante.
La verdad es que una buena estrategia de “link building” no es fácil de implementar.
Requiere tiempo, esfuerzo, paciencia…. y lo mas importante: sentido común.
Lo que si es importante antes de empezar… es tener en cuenta varios factores que pueden ayudar a:
Os dejo los “top 10″ factores que, a mi entender, son importantes de interiorizar.
1. Buy links from websites which exercise editorial integrity.
Google themselves recommend webmasters submit to Yahoo! Directory, which is nothing more than buying a link.
From Google’s Webmaster Guidelines:Submit your site to relevant directories such as the Open Directory Project and Yahoo!, as well as to other industry-specific expert sites.
A few directories I recommend: Yahoo!, DMOZ, V7N Directory, Aviva and Umdum.
When evaluating whether or not you should buy a link from a website - whether it be a web directory, or any other site - browse a few pages or more. If they sell links to Viagra sites or debt consolidation sites, even though the site at hand has no connection to those topics, then it’s fairly obvious that the website owner is not exercising editorial integrity. Buying links there could trip a filter.
2. Vary Your Anchor Text
A good rule of thumb is to never buy the same link twice. If you are targeting “web hosting”, you can vary your anchor texts like so: web hosting provider, reliable web hosting, quality web hosting, PHP web hosting, affordable web hosting, etc.
One of the easiest filters for a search engine to put in place is one which detects and devalues links with identical anchor texts.
3. Buy Non-Keyword Links
One of the hardest things for the simpleton SEO to do is to buy non-keyword links. If only he could see for himself the rewards of those SEO’s who buy non-keywords links.
But of course, anybody can see those rewards. Just do a search on Google for the keyword of your choice, and then analyze the backlinks of the websites in the top ten. You’ll most likely discover that a surprising majority of those links do not contain keywords.
Click here. <- A fine example of a non-keyword link.
Domain authority rules the SERPs. It has for some time now. Don’t think of links for web pages; think of links for the domain and for establishing domain authority.
4. Avoid Site-wide Links
Footer links aren’t necessarily evil. They just don’t help as much as you might think, and footer links can trip those pesky link spamming filters.
5. PageRank Zero Can Pass Link Weight
Yes, PR0 pages can still pass link weight. In one test, I linked to a webpage with a made up word as the anchor text, from a PR0 page. On the basis of the PR0 link, the linked-to page outranked the linking page on Google.
6. Avoid Automated Link Spamming
People are lazy. Search engines love it.
Automated link spam such as referral log spam, blog comment spam and automated web directory submission to hundreds or thousands of web directories; these all have one thing in common. Automation. They most often duplicate spam and create patterns that are easily detected and devalued by search engines.
Sure, I know it’s tempting, but don’t do it. You might as well just send Google a certified letter confessing to your spam.
7. Image Links And ALT Text
Don’t forget about image links and the attached ALT text. From my experience, image links are not subject to all the scrutiny and filters that text links are subjected to. And ALT text is treated the same as the anchor text of a text link. Yummy.
8. A Link On A Page Is Not The Same As A Link On A Page
Search engines have the ability to see pages like a human would. Google is able to evaluate links with regard to their placement on a web page. Links that are placed in the footer or in an area that is unlikely to be seen by a human visitor carry less weight than links that are placed above the fold.
9. Do NOT Rent Links
One of the first things Google started looking at when they began being more critical of links is the age of those links. Links appear to not pass full link juice in the beginning. It’s like a link is on probation. Once that link stays where it’s put for a while, then it;s given full credit. Or I should say, the web page it links to is given full credit.
Rented links should not form the basis of your link popularity. Permanent, stable links should account for 75% or more of your link profile.
10. Google Tells You Where To Get Links
Do you want to rank for web hosting? Get links from these sites, especially those first ten.
Google has patent’s for algorithms which rerank results based on links within the initial subset, and Google shows you that initial subset.
In Summary
Links remain the most important part of any search engine marketing campaign. Links are SEO. The difference between link building in 2002 and link building in 2007 is that the search engines are better equipped to evaluate those links, and this forces website owners to up their game.
Keep building links, just be smart about it.
