For some, the word “optimization” conjures up thoughts of complicated mathematicsand data analysis. It can seem like one of those things that only a true “data geek” could ever hope to understand.

At its core, however, the science of optimization is really quite simple: It’s all about making improvements. It’s about taking what you already have and then — through experimenting and measuring — figuring out ways to make it even better.

Below are some best practices you can implement and experiments you can run for optimizing your social channels.

## Use the Proper Image Dimensions for Social Profiles and Posts

If you don’t pay attention to the dimensions of the images you’re uploading and sharing, you could end up with unpleasant cropping or distorting. This is especially true when it comes to social media cover photos.

To ensure your social profiles showcase your brand and business in the best possible light, stick to the recommended image dimensions (in pixels) that the social networks provide. Here’s a list of dimensions for Facebook, Twitter, LinkedIn, Google+, Pinterest, and YouTube. All dimensions are given as width x height.

• Cover photo: 851 x 315
• Profile picture: 160 x 160 (upload as 180 x 180)
• App icons: 111 x 74
• Timeline: 504 x height is up to you (shared image), 484 x 252 (shared link)
• News feed: 470 x 394 (shared image), 470 x 246 (shared link)

• Header image: 1252 x 626, 1500 x 500 (redesign)
• Profile picture: 250 x 250
• Image in feed: 1024 x 512

• Banner image: 624 x 220
• Logo: 100 x 60
• Link Thumbnail: 100 x 100

• Cover photo: 1010 x 608 (recommended), 480 x 270 (minimum), 2120 x 1192 (maximum)
• Profile picture: 250 x 250
• Image post: 4:3 aspect ratio (800 x 600 minimum)

### Pinterest

• Board cover: 217 x 147
• Preview image: 51 x 51

• Banner image: 2560 x 1440 (TV), 2560 x 423 (desktop), 1546 x 423 (mobile)

## Test Post Frequency to Find Your Sweet Spot for Each Network, will help Optimizing Your Social Media Channels

The data shows that for Facebook, posting once every two days was the optimal frequency for generating Likes. For Twitter, tweeting between 1 and 4 times per hour proved to be the most effective frequency (as determined by the average clickthrough rates of tweeted links).

While these numbers can serve as great reference points, it’s important to remember that your ideal posting frequency will depend on how many overall posts are filling the feeds of your social followers and subscribers.

For example, if the majority of your Twitter followers only see around 20 total new tweets in their feeds every hour, and you tweet at a rate of four times an hour, that amounts to 1 in every 5 of the tweets they see coming from you. Seems a little spammy, right? By learning about your follower and subscriber base — and testing different post frequencies — you can mitigate social “spamminess” and optimize for engagement and lead generation.

Here’s a simple strategy for determining your optimal post frequencies. First, for each network you’re testing, schedule your posts apart by two hours, and stick to that posting frequency for a week. During that time, make sure to keep an eye on your key social metrics (Likes, shares, clickthrough rates, leads generated, etc.).

The following week, reduce the buffer time between your posts to an hour and a half, and see if (and how) that reduction in post frequency affects your metrics. Continue to reduce the buffer time between your scheduled posts week over week, and through some simple analysis, you can hone in on the post frequencies that maximize the metrics you want to optimize for.

## Figure Out the Best Times to Post

In addition to having calculated ideal post frequencies, Zarrella looked into the best days and times to post to various social media channels.

For example, his data showed that when it comes to expanding your reach on Twitter, 5 p.m. is the best time to tweet. (That’s when the highest percentage of retweets occur.) For Facebook, noon and a little after 7 p.m. are the two top times for maximizing your reach, as those are the two times of day when Facebook shares spike.

Ultimately, however, there are many different studies that all point to different ideal days and times for posting. So, as was the case with post frequency, you’ll need to do some testing to figure out your ideal post times.

To start, open up your social media publishing tool and sort your past posts by the number of clicks they’ve received. By scrolling through this list, you should be able to identify any prominent trends related to post timing. For example, if you see that seven of your top ten most-clicked LinkedIn posts were shared between 1 p.m. and 2 p.m., that’s a good indication that 1-2 is your LinkedIn posting “sweet spot.”

## Integrate Social With Your Other Marketing Channels

For the sake of organization  your marketing channels don’t live in silos: They’re all interconnected.

When it comes to social media, this interconnectedness is especially apparent (and important). Here are a couple of tips to help you integrate social with your other marketing channels.

If you haven’t done this already, stop what you’re doing and get on it! Google Authorship ties your Google+ profile to your blog posts, which allows Google to display information (e.g. your name, profile image, and the number of circles you’re in) next to your posts when they appear in search engine results pages (SERPs).

While marketers continue to quantify the benefits of setting up Google Authorship, many have found it has a positive effect on clickthrough rates and page views.

### Incorporate social sharing and follow buttons into your emails and thank you pages.

Your blog isn’t the only channel that can benefit from having social buttons. By incorporating these buttons into your emails, you can help drive more opens, clickthroughs, and conversions, and — more generally — you can make it clear to your contacts that there are other places where they can engage with you on the web (e.g. Facebook, Twitter, LinkedIn etc.).

Thank you pages are another easy-to-overlook location where adding social buttons can make a difference. These are the pages where people actually download or access your content after filling out one of your landing pages.

While we recommend removing all navigation links (including social buttons) from landing pages to make sure people focus on filling out the forms, with thank you pages it’s a different story: Visitors have already submitted their contact info, so if you can convince them to share your content, awesome! Just make sure that when you set up your social sharing buttons, they point to a landing page (and not the thank you page itself).
