Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
Create a spreadsheet to monitor your results. It’s a good idea to make a note of the post’s original post date, original word count, the date updates were made, and the new word count. Also note the number of post views during the 30 days prior to your changes, along with a summary of changes made and any other important metrics you want to track. Check your traffic after 60 days to see if traffic has increased.
That's why it's necessary to always stay abreast of developments in the SEO world, so that you can see these algorithm updates coming or you can determine what to do once they’ve been released. The WordStream blog is a great resource for SEO updates, but we also recommend Search Engine Land and Search Engine Roundtable for news on updates. Glenn Gabe of G-Squared Interactive is also a great resource for analyzing the causes and impact of algorithm updates.
Keyword Relevance – It’s critical to choose keywords to optimize for based on how relevant they are to your products or services. If your keywords are not intrinsically relevant to what you're offering on your website, the traffic the search engines feed your website will not be delivered a relevant message. Thus, they will be unable to complete the “search and reward cycle.” You see, searchers seek relevance and without it you're unlikely to convert them into customers.
I simply make the point that this research is still being influenced by what works for search. This is a mistake. For example, there are some topics that don’t need 2,000 words to provide the reader with in-depth value. So, if you take a topic that only requires 1,000 to cover it well and stretch it to 2,000 words, what do you think will happen with your user engagement?
Using this data can help you identify additional “buyer” keywords to target and what keywords to stop targeting. Keyword research, content marketing, and link building are things that you need to constantly be doing, even when you reach the top of the search rankings. Many businesses think that they can slow down these efforts once they reach the top, but easing up on your SEO strategy will see your competition take over the top position if you are not continually improving your search engine optimization effort.
For those unfamiliar with the extensive list of technical jargons, or otherwise lack experience in the industry, the intricacies of web development can be confusing at best and desperately overwhelming at worst. If you are a business owner, you are more than likely trained in practices directly related to running your business rather than, say, how to best impress and conquer Google rankings.
