In order to optimize your site, you need to make sure you are including the keywords that you want to rank for multiple times throughout your site. Also, ensure your site has complete and up-to-date contact information, that you’re using appropriate meta tags, and that you include pertinent business information as text—not text on images that Google can’t search.
If you find any broken links on topically related websites, you can immediately contact the website owner and inform him about it. Since you will do him a favor by pointing out a broken link, you can also kindly request a replacement with a link to your relevant resource. Of course, the replacement – your article – must be informative and useful for their audience.
You should build a website to benefit your users, and any optimization should be geared toward making the user experience better. One of those users is a search engine, which helps other users discover your content. Search Engine Optimization is about helping search engines understand and present content. Your site may be smaller or larger than our example site and offer vastly different content, but the optimization topics we discuss below should apply to sites of all sizes and types. We hope our guide gives you some fresh ideas on how to improve your website, and we'd love to hear your questions, feedback, and success stories in the Google Webmaster Help Forum1.
Many small businesses fail to write clear, concise headlines on their websites. Headlines are a big ranking factor for Google and other search engines. Because headlines are big and important looking, many small business owners are tempted to write clever or fun headlines, but this is a mistake. Instead, write headlines that convey a single who, what, where, when, or why statement that summarizes the content that follows. Imagine someone only reads the headlines—will they understand the content on your page? Clearly written headlines will help your readers and search engines understand your content.
Reviews are important to your small business because having reviews—especially positive reviews—is a ranking factor on Google. People are also more likely to click and visit your business if it’s listed with a lot of good reviews. To get reviews, start by asking your loyal customers and even your staff to leave reviews on major sites such as Google and Yelp.
Expertise and authoritativeness of a site increases its quality. Be sure that content on your site is created or edited by people with expertise in the topic. For example, providing expert or experienced sources can help users understand articles’ expertise. Representing well-established consensus in pages on scientific topics is a good practice if such consensus exists.

Having large groups of content that all revolve around the same topic will build more relevance around keywords that you're trying to rank for within these topics, and it makes it much easier for Google to associate your content with specific topics. Not only that, but it makes it much easier to interlink between your content, pushing more internal links through your website.

When Googlebot crawls a page, it should see the page the same way an average user does15. For optimal rendering and indexing, always allow Googlebot access to the JavaScript, CSS, and image files used by your website. If your site's robots.txt file disallows crawling of these assets, it directly harms how well our algorithms render and index your content. This can result in suboptimal rankings.

Take your competitors’ SEO work and apply it to yourself. For example, when writing your meta titles and descriptions, look at your competitors’ paid ads on Google for your keywords. Do they all mention a word or phrase (“complementary” or “free estimates,” for example)? Try using those to improve your titles and descriptions. After all, they spent money testing theirs out.
If you are using Responsive Web Design, use meta name="viewport" tag to tell the browser how to adjust the content. If you use Dynamic Serving, use the Vary HTTP header to signal your changes depending on the user-agent. If you are using separate URLs, signal the relationship between two URLs by tag with rel="canonical" and rel="alternate" elements.
Next, log into Google AdWords and click “Tools” > “Keyword Planner.” Once you’re on the Keyword Planner menu, click “Search for new keywords using a phrase, website or category.” Complete the form that appears; to start with, search for your type of business and location. For example, if you own a hair salon in Chicago, you would want to enter “hair salon Chicago.”
