If a keyword phrase contains another keyword phrase (eg. "one two three four five" → "one two three"), does improving SERP ranking for the shorter phrase "one two three" (using backlinks) automatically improve SERP ranking for the longer keyword phrase "one two three four five"?
Assuming the phrase is: "android phone battery exchange and repair"
You are in luck. Any of these keywords should perform well on their own or in small phrases. As well, the phrase would not be inappropriate for a page title either.
I tend to recommend a slight modification of the headline read order method. It just plain works though you will need to play around with the various elements to fine tune it to your purposes.
First Steps: For each page, and you can use a spread-sheet for reference if it helps, create a list of the top 2-3 most important keywords for the page. In another list, create the next 3-7 (or more if it applies) keywords for the page. That is it. One list with just a few most important keywords and another list with additional important keywords.
This will seem out of order, but it is not.
Title Tag: Each page
title tag should contain your 2-3 most important keywords for the page. In your case, it appears that your entire phrase can work just fine. The
title tag should be conversational and compelling. Your
title tag should not exceed about 50 characters, though the limit is 512 pixels. Your
title tag may need to be shorter if you have more wide characters such as W, Q, M, D, etc. Do not make a
title tag that is too short. If you create a good
title tag that is good in length, Google will use it as the SERP link. This is what you want.
Description Meta-Tag: You will want to create a
description meta-tag that is conversational and compelling. You want to shoot for two lines. Three lines is fine too, but one line is likely too short. Your
description meta-tag should have your most important keywords along with a few or more additional keywords. If done well, your
description meta-tag will be used for your SERP snippet. But this only happens if you can anticipate search terms and use the bulk of them in your
description meta-tag. Do not get carried away. Your
description meta-tag should never be a copy of your
title tag. I also discovered that a
blockquote tag can be substituted for a
description meta-tag as the SERP snippet. However, do try and make your
description meta-tag work first, and if you decide that a
blockquote tag is a good idea for your site, try and tune it for additional keywords not covered in the
H1 Tag: You will want to create a
h1 tag that is similar to your
title tag but not identical. It should not appear to be a copy or a close copy of the
title tag. Think in terms of a headline. What is the headline for the content? The
h1 tag should have the same most important keywords you used in your
title tag plus a few more. If your
title tag is not used for the SERP link, often, the
h1 tag will be if done right. Think in these terms. So make the
h1 tag conversational and compelling.
Other Header Tags: You will want to create
h3, and not likely but possibly,
h4 tags and so on. Generally, most pages do not use more than
h3 tags so do not get carried away. Each additional header tag should use your other important keywords plus your most important keywords used differently. In this case, you will be targeting keywords from your additional important keywords list. For example: MyPetCo Nutritional Dog Food (title) and The Best Nutritional Pet Foods For Your Dog (header).
Each paragraph immediately following any header tag should also contain as many of the header tag keywords as is natural to do. Make sure you write naturally.
h1 tag supports
title tag, the
description meta-tag supports both the
title tag and
h1 tag, and each paragraph immediately following supports the header tag.
All links that you create should vary quite a lot. Think conversationally. I create three types of links: page title links, keyword or keyword phrase links, and a headline link based upon the
h1 tag. You will want to create links for all three cases. However, when creating keyword or keyword phrase links within content, make sure you vary the keywords you use as much as possible. One, two, three, or five keywords is fine. Just make sure that the links that you create are natural in nature and fit within the content and page and are appropriate for the page that you link from and to. This is important. You will want to make your links seem organic and one way to do this is if the vary. Of course, truly organic links are always the best. These are the links that others make to your site.
This is the general idea behind the headline read order plus I added one of my own secrets. (Ssshhhhh! Don't tell anyone- it is just between you and I.) SEO is really simple, however, you will need to tune things a bit. No one gets it right the first time, but after a short while, you will get a feel for what works best for your site. One trick is to use the Google Webmaster Tools > Fetch as Google Tool to get a feel for how a SERP link and snippet might look. One warning however. What you will see in the tool does not always match what actually happens in the wild. It is close though. It will help you to visualize your SERP link and snippet and make it as compelling as you can which is the point. If the SERP link and snippet is not compelling, no-one will click on it. You will want to play around with this too.
