Internet Marketing is an extremely new industry.

Search Engine Optimization

15. Besides the Big 5, keep an eye out for Tumblr and Instagram. Depending on your industry, these niche sites could be where you put the most of effort and time to reach a relevant audience.
16. The 6 major “investment” areas for SEO are: crawlability, site structure, on-page optimization, content development, links and social media. – Duane Forrester at Salt Lake’s Search Marketing Event.
17. Content isn’t everything; there’s still a lot more to SEO that simply involves technically optimizing your site and existing assets).

Social Media

Images

33. Don’t forget about images on your product pages and blog posts. Visual cues help the reader digest written content and stay on the page longer.
34. If you’re an eCommerce website, consider placing a “pin it” button on every single one of your products for Pinterest. It’s done wonders for Sephora.
35. Place this link in your browser and replace “YourWebsite” with your website to see which of your images are on Pinterest: http://pinterest.com/source/YourWebsite (or your competitors…)
36. Pinterest just rolled out Analytics for their site, in preparation to monetize. First you need toverify your business account. Switch to the new look. Click on the Anlaytics tab and viola!
37. Pinterest boards rank in Google, not individual pins. Make your boards as specific as possible and add as much content that relates to that topic as you can.
38. Pinterest and Instagram contests are great, but make sure your end goal is relevant followers; not just “new” followers.

Content

66. Bloggers should take note, and act a little bit more like Kanye West.
67. Context (noun): The parts of a written or spoken statement that follow a specific work or passage, usually influencing its meaning or effect. Context is everything in internet marketing.
68. Check your Google Analytics and see which of your blog posts perform well. There might be opportunity to update and re-publish them. (Like we did with 71 Chrome Extensions for Blogging & SEO).
69. Slideshare is a great way to breathe new life into your best content by repurposing it in another format.
70. Google can crawl Slide shares for links, which is why they can be a powerful part of your content/ link-building strategy.
71. We live in a digital world where a lot of information is re-packaged but in a different way. If you’re repurposing ideas, you better make them your own.
72. When commenting on blog posts, G+ Communities, etc. actually adding to the conversation goes a lot farther than a simple, “good post.”
73. Search engines REALLY DO respond to unique, useful content.

Ingredients for Great SEO

First things first, I really like chocolate milkshakes. (There, I said it… No turning back.) I think they are delicious and no two are exactly the same. (Unless you buy two from same place, then they’re more or less exactly the same.) Though some are chocolat-ier and some are creamier than others, a chocolate milkshake is still a chocolate milkshake. Unless you go to Wendy’s, then it’s called a Frosty and it's delicious. 

On-Page SEO (AKA the Ice Cream)

• Having a Unique Page Title is very important to SEO as well. If every page is titled the same “Home | Best Potato Salad” or “Blog | Best Potato Salad,” it can limit your site from being ranked for multiple keywords.
• Page format and style are additionally an important factor in SEO. A best practice is to design a clutter-free page with the most valuable information above the fold, or invest in responsive web design If your page features a large amount of ads above the fold, it is likely to get dinged in the search engine results page (SERP).
• Writing Unique Meta-Keywords and Meta-Descriptions are essential to gaining a higher click-through-rate. Most search engines no longer use this Meta-Data in their algorithm for results, but it will help you draw people into your site. A common mistake I see is that people use the same Meta-Keywords and description on every page. (“Our Potato Salad is the Best Freakin Potato Salad you’ve ever had, period!) Make your description unique, but relevant to every page. As far as length, you’ll want to keep your Meta-Keywords to 70 characters or less, and your Meta-Description to 150 characters or less.   
• Placing Alt Text on any images you have on your page will help those images appear in the Image SERP. The text should be relevant to the picture.
• Using proper header tags throughout your page (H1, H2, H3, etc.) shows the search engine bots a level of importance. The title of your page should be in H1 format, giving it the highest importance. The subtitle should be in H2.
