Hey Sammy, I would always advise against buying traffic, social followers, or anything else in that area. It mostly ends up being a vanity metric without business benefits. It’s always better to earn the traffic by creating a valuable, high-quality website and marketing it properly. When you do that, you attract the kind of visitors who are interested in what you have to offer, which is usually better for the bottom line.
When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.
If you're looking to upload an image to a blog post, for example, examine the file for its file size first. If it's anywhere in megabyte (MB) territory, even just 1 MB, it's a good idea to use an image compression tool to reduce the file size before uploading it to your blog. Sites like TinyPNG make it easy to compress images in bulk, while Google's very own Squoosh has been known to shrink image file sizes to microscopic levels.
Achievable: Make sure you're grounding your goal in reality. Sure, you can't control a massive Google update, but using the history of your sales and competitive data, you can make some inferences. You also need to make sure you have agreed-upon goals. Get buy-in before you set the goal in stone, leveraging the thoughts from the leaders, merchandisers, analysts, and anyone who might be able to provide insight into the likelihood of hitting your goal.
What is the leadership like? What kind of culture do they cultivate? In smaller companies, the leaders tend to influence the culture. In larger companies, unfortunately, this can get lost. But if you have access to the leadership, spend some time learning about their vision. It should match up to the company's core values, but sometimes there are more gems locked in their minds.
Lastly, it's important to remember that paralysis by over-thinking is a real issue some struggle with. There's no pill for it (yet). Predicting perfection is a fool's errand. Get as close as you can within a reasonable timeframe, and prepare for future iteration. If you're traveling through your plan and determine a soft spot at any time, simply pivot. It's many hours of upfront work to get your strategy built, but it's not too hard to tweak as you go.
