Your portfolio must be complete: profile, services, experience, examples of work, etc. Think carefully about the content and how you organise it.
Use the software's layout formatting functions to define: headings, sub-headings, bold text, etc. Search engines analyse the layout of the words to decide on their importance compared to the rest of the page. A word's importance depends on how it has been formatted: Heading > Sub-heading > Bold text > Standard text, combined with the proportion of each type of text on the whole of the page: the less bold text there is on a page, the greater the importance attributed to each word in bold compared to the rest of the text (the same applies to headings). If you use bold for all your text, it will end up highlighting nothing.
By optimising the content for your visitors, you are also optimising it for the search engines.
If you insert a link on page A to page B and use "actor CV" as the link text, this will improve the listing of page B in search engines for searches using "actor" or "cv" as search terms. Do not use "Click here" or an URL address for your links; use the title of the destination page as the link text.
This type of link :
By filling in a title for every image/photo on your website you improve accessibility for the visually impaired that use screen readers and you also improve your ranking in search engines.
The title must describe the image by taking into account the context: it must not reuse information already published on the page (title of the gallery, description underneath the image etc.)
Getting a site listed involves submitting it to website directories and exchanging links with other sites. Links towards your portfolio bring you direct and indirect visitors by increasing the popularity* of your portfolio with search engines.
The search engine will scan and record (index) every page on your site in its database. Subsequently, it will return to regularly update its information by re-recording the pages (the more popular* the site, the more frequent these updates). Search engines move from site to site and page to page, so if your portfolio is listed in the Artfolio directory, it will automatically be recorded by the search engines.
The search engine looks at page CONTENT and POPULARITY* to define its ranking (position) in the results.
*Popularity: The more internet links there are towards your portfolio, the more popular your site is considered to be by search engines. The greater a site's popularity, the better its ranking. Your position in the search engine rankings is thus dependent on your presence on other sites. The greater the popularity of a site, the greater the popularity that it confers on its links. However, the number of links on a page also has an effect on the amount of popularity that is conferred: the fewer the number of links, the greater the amount of popularity that is transferred to each of them.
To improve your popularity, you can submit your portfolio to web directories, exchange links with other sites or simply "harvest" natural links.
DMOZ is the most popular website directory.
In contrast to search engines :
Exchanging links (or reciprocal links) involves adding a link to another site (partner) in exchange for a return link to your site.
The link's context is important. A link will get a better ranking in search engines if the linked pages have a similar subject matter. Preferentially select the sites that are likely to interest your visitors (having a subject that is similar to yours).
Add a few words within the link text to improve the listing of your partner sites for these key words.

Patrick - Fashion photographer
Your home page is often the most popular page as this is the page towards which most of the links to your site point. If you put your external links (partners) on the home page, you will "dilute" the popularity that the page confers on your internal links (CV, News, etc.). It is therefore recommended that you place your external links on a page dedicated to your partnerships.
An interesting content will provide you with "natural links" (discussion forum, blogs, etc.).
Getting listed requires a lot of time. When done well, a good quality listing will avoid useless contacts (and appointments). By taking care with getting listed, you maximise your chances of being contacted by people who are interested in your work.
