Facebook ads contain links back to your business’s page. Even if the goal of your ads is to get people to click on a link that takes them off of Facebook, there’s a chance they’ll go directly to your Facebook page to learn more about you. If your page is empty or outdated, that’s where their curiosity ends. If you’re spending the time and money to advertise on Facebook, make sure you follow through with an up-to-date Facebook page.
The objective of (SEM) is to drive traffic to your website with the intent of converting those visitors into customers. With SEM, it is important to have your business site listed near the top of the search engine rankings since very few internet users will actually look at search results beyond the first couple of pages. SEM can be divided into two categories: organic and paid. Both are important.
Page and Brin founded Google in 1998.[22] Google attracted a loyal following among the growing number of Internet users, who liked its simple design.[23] Off-page factors (such as PageRank and hyperlink analysis) were considered as well as on-page factors (such as keyword frequency, meta tags, headings, links and site structure) to enable Google to avoid the kind of manipulation seen in search engines that only considered on-page factors for their rankings. Although PageRank was more difficult to game, webmasters had already developed link building tools and schemes to influence the Inktomi search engine, and these methods proved similarly applicable to gaming PageRank. Many sites focused on exchanging, buying, and selling links, often on a massive scale. Some of these schemes, or link farms, involved the creation of thousands of sites for the sole purpose of link spamming.[24]
Together is better! For many businesses, the best approach is a mix of both organic and paid search results. The advantage of this approach is that organic rankings give a business credibility and evergreen search results. Paid search (PPC) provides immediate top-of-the-page listings and greater click through rates, i.e., sales, when consumers are ready to purchase.
The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. The Yahoo! Directory and DMOZ, two major directories which closed in 2014 and 2017 respectively, both required manual submission and human editorial review.[39] Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links[40] in addition to their URL submission console.[41] Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click;[42] however, this practice was discontinued in 2009.
I'm thinking about "less to do" (linking-social media) sites with physical products … Amazon and other merchants. And adding a PPC campaign instead of using social media and constantly toiling away building links and writing articles. Is there an easy way to get sites like this to rank while profiting with some paid traffic? Your opinion on this dilemma .. SEO vs PAID traffic or both would be much appreciated.

Google is moving into more and more aggressively commercial spaces, like jobs, flights, products, all of these kinds of searches where previously there was opportunity and now there's a lot less. If you're Expedia or you're Travelocity or you're Hotels.com or you're Cheapflights and you see what's going on with flight and hotel searches in particular, Google is essentially saying, "No, no, no. Don't worry about clicking anything else. We've got the answers for you right here."
Another tip you can use is just reach out to the prior agency and say something like the following: “We realise you were using link networks for our website which has resulted in a Google penalty and loss in business. Can you please remove my website from any link network you have built?”. If the prior agency is decent, they will remove the links from the network.
This means that each organic search visit is worth $7.35. Chances are, you’ll spend WAY less than that to generate that one visit. How’s that for some rock-solid ROI? You can get even more specific with this by looking at the organic search traffic for a particular keyword. By extension, you can calculate the ROI of that keyword. You can begin to see how this can ramp up your SEO game.

The Google, Yahoo!, and Bing search engines insert advertising on their search results pages. The ads are designed to look similar to the search results, though different enough for readers to distinguish between ads and actual results. This is done with various differences in background, text, link colors, and/or placement on the page. However, the appearance of ads on all major search engines is so similar to genuine search results that a majority of search engine users cannot effectively distinguish between the two.[1]
