(upbeat music) As search engines analyze your page during the crawling process, they look at specific aspects of your content. When we say content, we mean the hypertext markup language, or HTML, of your page. Search engines look at the source code that the page is based on. Your browser interprets that code and displays what you actually see, but the search algorithm sees things that aren't displayed by the browser. Things like the head section of the HTML code, which includes the title tag, the meta-description of the page, meta tags that give instructions to the search algorithm, and hidden information. The part of the page that displays in the browser contains certain key HTML code signals. These include head tags, for example, H1, H2, H3, tables, image alt tags, and keywords. Keywords are the most obvious and talked about of the on-page SEO factors, but a search keyword is seldom just one word. It's often a multi-word phrase that a searcher uses to find what they're looking for. Keyword means any type of search phrase whether it's single or multi-word. Let's look at the factors that define on-page SEO. When scanning the HTML code, search engines look for the page's focus keyword in several locations. The title tag in the head section of the page, the meta description in the head section, the URL of the page, the H1 head tag, which is the most important head tag, other head tags in the first paragraph and in the last paragraph. By scanning these items, the search engine learns what the page is about. A repeated keyword tells the search engine that this keyword is the main focus of the page. It also considers synonyms and various reordering of the main keyword. The more variations it finds that make sense, the more it reinforces that keyword as the page's focus keyword, but there's a limit. If the search engine sees the keyword repeated in an unnatural way, it will penalize the page. If a human would notice it's overused, it's likely the search engine will, too. How do you make sure the focus keyword is clear to search engines? Just write normally and focus on readability for humans first. A well-written page will naturally reuse the keyword and its variations. The locations where you'll want your keyword are: The title tag, the URL, the first sentence on the page, the last sentence on the page, the first H1 tag, and internal links from other pages on your site to that page. Knowing some HTML will be very helpful as a search engine optimizer. You'll often wanna look under the hood at the source code of your site and your competition sites to check for various on-page elements and HTML tags that are important to SEO. The goal of an online marketing tactic may not always be to sell something. Other key performance indicators, or KPIs, could be important to your business. Sometimes intermediate actions indicate buying intention, even if they don't indicate bottom of the funnel intention. For example, if someone is just beginning their search for a solution to a problem, top of the funnel, we still want to attract them to our page. Maybe we'll entice them to join our marketing funnel with an email signup and get them to remember us. This could be an opportunity to pre-sell with credibility and trust that might get them to come back when they are ready to buy. Keyword research is about finding the best possible keywords that will have a higher search ranking. It'll help to use keywords that have high demand but low supply. Fewer sites are optimized for that keyword but a lot of searchers want it. How do we find those keywords? There are some tools available, like Google Keyword Planner, Semrush, Moz Keyword Explorer, SOOVLE, and Ahrefs Keyword Explorer. Some of these tools are free, but some charge a monthly subscription. Another topic of SEO discussion is long-tail keywords, which are more specific and usually longer than more common keywords. Long-tail keywords get less search traffic but will usually have a higher conversion value. They're more specific to a searcher's intent. They allow you to gradually get more traffic to your site and be found by new and specialized audiences. A good source of long-tail keywords is the Google keyword suggestions you get when you do a search. This Google feature shows search suggestions when you are entering a key phrase. Often, these are the long-tail phrases you're looking for and indicate Google has already shown a preference for these phrases. Here's what that section looks like when you search. Suggested keywords help your content resonate with your audience for successful search engine optimization. Website navigation gives search engines their first links involved with your site. Here's an example of the HTML code for an on-page hyperlink. The first part is where the link leads on the internet, the URL of the page, and the second part, called the anchor text, is what the user sees in the browser or perhaps in an email. Search engines follow these links when crawling a page and also keep track of the wording in the anchor text.
