(spread across a number of pages) which lists something like 1,000 restaurants in a large city with contact details and a web link to each of those restaurant’s home page. Given that the outgoing links are relevant to my content, should I or should I not be using REL=nofollow for each link given the massive quantity of them? How will my ranking for pages containing those links and pages elsewhere on my site be affected if I do or don’t include REL=nofollow for those links? My fear is that if I don’t use REL=nofollow, Google will assume my site is just a generic directory of links (given the large number of them) and will penalize me accordingly.
In both versions of my model, I used the total of my initia esitimate to check my math was not doing south. After every iteration, the total Pagerank remains the same. This means that PageRank doesn’t leak! 301 redirects cannot just bleed PageRank, otherwise the algorithm might not remain stable. On a similar note, pages with zero outbound links can’t be “fixed” by dividing by something other than zero. They do need to be fixed, but not by diluing the overall PageRank. I can maybe look at these cases in more depth if there is some demand.
Say I have an article on a blog with 5 links in the editorial copy — some of those links leading back to other content within the blog that I hope to do well. Then I get 35 comments on the article, with each comment having a link back to the commenters’ sites. That’s 40 links in all. Let’s say this particular page has $20 in PageRank to spend. Each link gets 50 cents.
Matt, this is an excellent summary. I finally got around to reading “The Search” by John Battelle and it was very enlightening to understand much of the academia behind what led to the creation of Backrub.. er Google.Looking at how many times the project was almost shutdown due to bandwidth consumption (> 50% of what the university could offer at times) as well as webmasters being concerned that their pages would be stolen and recreated. It’s so interesting to see that issues we see today are some of the same ones that Larry and Sergey were dealing with back then. As always, thanks for the great read Matt!
And if you really want to know what are the most important, relevant pages to get links from, forget PageRank. Think search rank. Search for the words you’d like to rank for. See what pages come up tops in Google. Those are the most important and relevant pages you want to seek links from. That’s because Google is explicitly telling you that on the topic you searched for, these are the best.
After that, you need to make a choice about how to construct an online presence that helps you achieve that goal. Maybe you need to set up an e-commerce site. If you’re interested in publishing content to drive awareness and subscribers, look into setting up a blog. A simple website or landing page with a lead capture form can help you start developing your brand and generating traffic. A basic analytics platform (like Google Analytics, which is free) can help you start to measure how you are tracking towards your initial goal.
So, as you build a link, ask yourself, "am I doing this for the sake of my customer or as a normal marketing function?" If not, and you're buying a link, spamming blog comments, posting low-quality articles and whatnot, you risk Google penalizing you for your behavior. This could be as subtle as a drop in search ranking, or as harsh as a manual action, getting you removed from the search results altogether!
I dont know if Google gets its kicks out of keeping Search Engine Marketers and Webmasters jumping through hoops – or if they are in cahoots with the big SEM firms – so that they get this news and these updates before the average guy on the street. Either way, they are seriously getting a bit too big and powerful and the time is RIPE for a new search engine to step in and level the playing field.
The SEO industry changes at an extreme pace, every year marketers evolve their strategies and shift their focus. However, backlinks remain just as crucial of a strategy as when they were first created. Currently, backlinks are a very common phase in the world of SEO, and if you are involved in the industry, you know backlinks are vital to a website’s performance.
