Tip # 1 – post as often as you can
Regular blog posts not only keep your existing readers engaged, they also attract new readers and search engines.
Search engines index pages on their own schedule. There is nothing site owner can do to change their schedule, other than regular site updates.
When search engines see that your content changes daily and not weekly or monthly, they’ll start visiting your pages more frequently.Tip # 2 – keep it relevant to your niche
You can write on any subject, as long as you keep it relevant to your niche subject. This will help others, who land on your pages, get an idea of what your specialty is, and help search engines get relevancy right. This will also help you to establish yourself as an authority in your field.Tip # 3 – don’t try to sell
Don’t plaster your store name all over your blog post and don’t promote yourself in every sentence. If you write your posts as sales copy, you will lose readers. Also, you won’t get as many inbound links. People tend to avoid linking to blogs, that try to sell to their readers. Tip # 4 - provide unique quality content
Your content has to be unique and it has to provide value to your readers. Offer free tips, advice, share your experience, discuss news, related to your subject etc. Great content will increase your chances of being found by search engines. They constantly look for fresh content and will rank you well, if they find you relevant.Tip # 5 – use your keywords
Google feeds on good keyword-rich content. Decide on target keywords before you write a post. Ensure you use important keywords in the title of your blog post. Use your keywords throughout your content, but don’t just keep repeating them over and over. Ensure you use other semantically similar words.
When adding an image to your blog post, make sure you use descriptive words to name that image, like “silver-ring-flower-shape.jpg” and add an Alt tag for this image like “Flower shaped handmade sterling silver ring.” Not only you can see what each image represents without opening it. That will also help search engines understand what each image is about. That will strengthen the relevance of your post.Tip # 6 – provide enough copy
Search engines like copy and long articles. Human readers don’t always like long articles. So what you need to do as a blogger, is to strike a balance between the two.
If your blog post is only a sentence or two long, you will not be able to inject enough keywords in the copy to optimize it for search engines. If you can’t communicate relevancy to search engines, they will not include it in their search results. This means you’ll never have a big reach with that post, so why bother writing it? Not many people will find it.
Having a lot of images in the post doesn’t help either. Search engines can’t see them. So don’t replace copy with images, if you care about SEO.
