Search engines rank sites to help their users such as yourself find the best, most relevant sites. They take time to examine and index your site, and thus it takes time for SEO to increase or links listed to change. They know what the "tricks" are. Keep in mind it depends on a variety of factors including content, descriptions, link-backs, host, URL, and more!
Note: When you switching to and from websites (content or URL), your SEO may be refreshed as well, so you may have to work on these elements again.
1. Use Relevant Content Only
Google changed its algorithm and instead of focusing on just keywords, higher rankings are awarded to sites with more relevant content. Focus more on building websites for your users/visitors, and not for search engines.
2. Connect your domain! (Pro & Limited)
Your domain is the best keyword to search for your site. Connecting yourname.com or yourcompany.com will take you a long way. Here's how to do that.
If you won't be upgrading, don't worry, your http://page.strikingly.com URL has good SEO and loads quickly as well! Read more.
3. Actively share your site on other websites.
A huge part of search engine ranking comes from backlinks and traffic. That means the more sites that link to your site, and the higher the quality of those sites, the better your search engine ranking will be.
Start posting your site on blogs, forums and social media! Create a Google Plus profile, if relevant. Include your URL in your LinkedIn profile, email signature and other networks. Find the places where people are interested in what you do and share!
4. Complete page descriptions.
Go to Settings -> Basic Info -> Site Description. Your description should be a few sentences long, and you should have several keywords that categorize your site or business. However, be careful not to include keywords just for the sake of increasing your ranking, as many search engines demote this behavior (keyword stuffing) and rank you lower.
Good description: "Johnny's Bakery is a gourmet bakery and confectionery based in the Mission in San Francisco. We started in 1965 and we've been offering delightful breads, cakes, pies, and cookies to happy customers ever since!"
If you have multiple pages, you can also add meta descriptions for each page. Learn more here.
5. Write a descriptive title.
The title is the text that shows up in the title bar in the viewer's browser. This is like the front door of your page. Make it attractive! "Johnny's Bakery - Freshly Baked Everyday in San Francisco" is much better than "Johnny's Shop."
6. Add keywords to your headings.
Headings are the big text boxes that are located throughout your site. Titles are important for SEO because search engines give additional weight to heading text. So, it's better to add descriptive text in the headings. For instance, "About Johnny's Bakery" is better than "About" as a heading for your "About" section.
7. Add descriptions to all the images.
Since search engines don't understand images, they look for image descriptions. An image description will help search engines index your image, which helps index your site. These are the same as adding "alt" tags in HTML.
NOTE: Try to keep your image sizes under 200KB. The best size for website images (desktop and laptop) is around 50KB. This will improve performance and experience! The image quality is best if you compress it on your computer, prior to upload.
