In a recent SEO blog post, I referenced a few important SEO tasks to start with when optimizing a new website. One of those tasks is to upload an optimized robots.txt file to the root domain of the site.
The below graphic explains that concept a bit more.
Another important concept in SEO is the site ranking formula created by Google, called the Google PageRank. Basically, what the PageRank indicates is the overall authority a website holds on the Internet.
As you can see from the graphic below, the majority of websites on the Internet rank from 1 to 5. PageRank of higher than 5 is very much above average and only the most influential and credible sites on the Internet, such as Ebay.com, ESPN.com, and the mighty Google.com, make it into the 7 to 10 ratings because it takes exponentially more time and effort to make it to that level.
PageRank is very important from an SEO perspective because it gives us all an indication as to how much equity a website has built up, based on domain age, high-quality inbound links, traffic volume and quality, etc. If you'd like to see how well your website is doing online, check out your Google PageRank (keep in mind that a rank of 3 to 5 is average...anything above that is very hard to achieve).
FUN FACT: PageRank wasn't actually named for the obvious...that it is an indication of where a website/page ranks on a scale of 1 to 10. It was named after Larry Page, co-founder of Google, as mentioned in the infographic from another recent SEO blog post.
Lastly, but certainly not least, is a graphic that describes the SEO concept of "Long Tail Keywords". Long tail SEO keywords are very valuable to a successful SEO campaign because they are the most efficient keywords to target.
As you can see from the graphic, competition and cost for keywords is highest when the keyword phrases are very short and broad (e.g. "shoes"). As you begin to target more descriptive keyword phrases (e.g. "red Nike mens running shoes"), you begin to achieve higher efficiency because of the low cost and competition while increasing the probability of conversion.
If an online user is searching for running shoes, they are more often than not going to refine their search by typing in more descriptive phrases until they find the results they want. Once the user finds the relevant results they want, they click on a listing and go to a website where they are more likely to convert because they are satisfied with the search results.
The difficulty is that there are many more long tail keywords to target which is why the initial keyword research is so important. Finding the most efficient long tail SEO keywords to target is an essential part of a successful long-term SEO campaign.
