Howdy, Moz fans, and welcome to another edition of Whiteboard Friday. We are back with our final part in the One-Hour Guide to SEO, and this week talking about why links matter to search engines, how you can earn links, and things to consider when doing link building.
Let’s get real for a moment: As much as we hear about positive team cultures and healthy work environments in the digital marketing space, many of us encounter workplace scenarios that are far from the ideal. Some of us might even be part of a team where we feel discouraged to share new ideas or alternative solutions because we know it will be shot down without discussion. Even worse, there are some who feel afraid to ask questions or seek help because their workplace culture doesn’t provide a safe place for learning.
The Short Version: Don’t obsess over Domain Authority (DA) for its own sake. Domain Authority shines at comparing your overall authority (your aggregate link equity, for the most part) to other sites and determining where you can compete. Attract real links that drive traffic, and you’ll improve both your Domain Authority and your rankings.
Unless you’ve been living under a rock, over a rock, or really anywhere rock-adjacent, you may know that Moz has recently invested a lot of time, research, and money in a new-and-improved Domain Authority. People who use Domain Authority (DA) naturally want to improve their score, and this is a question that I admit we’ve avoided at times, because like any metric, DA can be abused if taken out of context or viewed in isolation.
At Wall Street Oasis, we’ve noticed that every time we focus on improving our page speed, Google sends us more organic traffic. In 2018, our company’s website reached over 80 percent of our traffic from organic search. That’s 24.5 million visits. Needless to say, we are very tuned in to how we can continue to improve our user experience and keep Google happy.
We thought this article would be a great way to highlight the specific steps we take to keep our page speed lightning fast and organic traffic healthy. While this article is somewhat technical (page speed is an important and complex subject) we hope it provides website owners and developers with a framework on how to try and improve their page speed.
Quick technical background: Our website is built on top of the Drupal CMS and we are running on a server with a LAMP stack (plus Varnish and memcache). If you are not using MySQL, however, the steps and principles in this article are still relevant for other databases or a reverse proxy.
Ready? Let’s dig in.
5 Steps to speed up the backend
Before we jump into specific steps that can help you speed up your backend, it might help to review what we mean by “backend”. You can think of the backend of everything that goes into storing data, including the database itself and the servers — basically anything that helps make the website function that you don’t visually interact with. For more information on the difference between the backend vs. frontend, you read this article
Step 1: Make sure you have a Reverse Proxy configured
This is an important first step. For Wall Street Oasis (WSO), we use a reverse proxy called Varnish. It is by far the most critical and fastest layer of cache and serves the majority of the anonymous traffic (visitors logged out). Varnish caches the whole page in memory, so returning it to the visitor is lightning fast.
Step 2: Extend the TTL of that cache
If you have a large database of content (specifically in the 10,000+ URL range) that doesn’t change very frequently, to drive the hit-rate higher on the Varnish caching layer, you can extend the time to live (TTL basically means how long before you flush the object out of the cache).
For WSO, we went all the way up to two weeks (since we were over 300,000 discussions). At any given time, only a few thousand of those forum URLs are active, so it makes sense to heavily cache the other pages. The downside to this is that when you make any sitewide, template or design changes, you have to wait two weeks for it to arrive across all URLs.
Step 3: Warm up the cache
In order to keep our cache “warm,” we have a specific process that hits all the URLs in our sitemap. This increases the likelihood of a page being in the cache when a user or Google bot visits those same pages (i.e. our hit rate improves). It also keeps Varnish full of more objects, ready to be accessed quickly.
As you can see from the chart below, the ratio of “cache hits” (green) to total hits (blue+green) is over 93 percent.
Step 4: Tune your database and focus on the slowest queries
On WSO, we use a MySQL database. Make sure you enable the slow queries report and check it at least every quarter. Check the slowest queries using EXPLAIN. Add indexes where needed and rewrite queries that can be optimized.
Use HTTP2 server push to send resources to the page before they are requested. Just make sure you test which ones should be pushed, first. JavaScript was a good option for us. You can read more about it here.
We’ve arrived at one of the meatiest SEO topics in our series: technical SEO. In this fifth part of the One-Hour Guide to SEO, Rand covers essential technical topics from crawlability to internal link structure to subfolders and far more. Watch on for a firmer grasp of technical SEO fundamentals!
